Working from home has risen vastly over the past year, and this trend looks to be here to stay. While a user may ignore occasional blips in their “for fun” internet, working from home requires a new level of network performance. Ensuring Wi-Fi® Quality of Service (QoS) is arguably the most important component of such performance, and Wi-Fi CERTIFIED QoS Management™ is now able to provide the reliability that working from home requires.

The importance of Wi-Fi QoS Management™ when working from home

Wi-Fi is becoming one of the most important approaches for connecting devices to the internet. Consumers are demanding that operators provide a high quality Wi-Fi experience when it comes to Wi-Fi connectivity across all devices. In particular, work-from-home, or telework, has emerged as a vitally important application supported by Wi-Fi. There is a growing need for operators to manage and ensure mission critical telework traffic over Wi-Fi, and residential connections should be managed to ensure connectivity and performance that enables productive employees. Wi-Fi CERTIFIED QoS Management has now emerged to ensure telework traffic is prioritized, resulting in an improved work-from-home experience for employees.

The technology driving Wi-Fi QoS Management

Wi-Fi CERTIFIED Wi-Fi Multimedia™ (WMM®) provides the over-the-air mechanisms to support traffic prioritization, including prioritization of work from home traffic. While WMM can prioritize telework applications to ensure their service quality, it did not provide the capabilities to link the Wi-Fi layer with the IP or application layers for residential Wi-Fi.

Wi-Fi CERTIFIED QoS Management simplifies the prioritization and management of latency-sensitive traffic in Wi-Fi networks by enabling IP data flows to be classified and mapped to one of four QoS access categories defined by WMM. This helps ensure that traffic for real-time applications and services is inserted into queues with higher priority, resulting in a better experience for end-users.

Wi-Fi QoS Management supports Differentiated Service Code Point (DSCP) mapping, which is a marking in the IP packet headers for managing network priority and QoS across the network. Wi-Fi QoS Management can classify traffic and map flows into DSCP code points, whereby work-related flows are identified and assigned to high priorities. Wi-Fi QoS Management then enables configuration mapping of the IP-layer DSCP markings to WMM categories, allowing for prioritization and ensuring QoS on Wi-Fi. The essential component of priority across the Wi-Fi link is enabled by Wi-Fi QoS Management. In addition, Wi-Fi QoS Management can similarly support Mirrored Stream Classification Service (MSCS) to ensure QoS of work applications on client devices across the Wi-Fi link.

Solutions available to harness benefits of Wi-Fi QoS Management

Solutions such as ASSIA Equipe are coming to market to harness the benefits of Wi-Fi QoS Management for employees working from home. This Wi-Fi management platform runs on Wi-Fi gateways and Wi-Fi extenders in conjunction with a cloud-based management system and a smartphone application that the employee interacts with. Equipe collects and analyzes many Wi-Fi performance-related parameters to determine and optimize “Workput”—an AI model that learns the true impact of an individual’s connectivity for telework. Ensuring work from home prioritization for Telework QoS is crucial to high Workput.

The use of Wi-Fi QoS Management by such solutions enables operators to take a great step forward by prioritizing critical workflows to support telework as a service. For instance, Equipe can use Wi-Fi QoS Management to assign high priority and support end-to-end QoS of Workput flows across the network, particularly across the crucial Wi-Fi link. It is Wi-Fi QoS Management’s ability to support prioritization of these flows that makes it so critical to telework, enabling employees to enjoy a high quality work from home experience.

In many households, Wi-Fi is shared between time-sensitive, performance-oriented work flows and more casual traffic. Wi-Fi QoS management enables mission-critical applications to meet their delay and quality requirements, ensuring the now-pervasive needs of telework can now be fully supported.

With the release of the fourth Wi-Fi 6 system from Calix, service providers now have a fully modular, upgradeable Revenue EDGE System with a 10-year plus lifespan that will simplify systems integration and deployment, significantly reducing CAPEX and OPEX, while establishing a “digital storefront” in subscribers’ homes

SAN JOSE, CA – May 11, 2021 – Calix, Inc. (NYSE: CALX) today launched the new GigaSpire® BLAST u6x, giving broadband service providers (BSPs) the only Wi-Fi 6 system capable of delivering up to 10 Gbps Internet services while providing the ultimate flexibility to seamlessly and cost-effectively upgrade subscribers’ access technology today and in the future. Now shipping, the GigaSpire BLAST u6x is the fourth system in the GigaSpire BLAST family, and is the world’s first Wi-Fi 6 system with options for five different WAN SFP connections to accommodate a wide range of deployment scenarios: 1 and 10 Gigabit Ethernet and GPON—with Active Ethernet and XGS-PON capabilities scheduled for later this year—covering future subscriber network deployment scenarios for upwards of a decade. The fully modular design and integration with the real-time analytics insights of Calix Support Cloud helps BSPs dramatically simplify the deployment process, shorten installation time, and minimize inventory issues—significantly reducing both CAPEX and OPEX.

 

Powered by the Experience Innovation Platform, the GigaSpire BLAST u6x is fully interoperable with the end-to-end Revenue EDGE solution, including the CommandIQ® mobile app and value-added services in EDGE Suites. By deploying the GigaSpire Blast u6x, a service provider establishes a “digital storefront” in subscribers’ homes from which it can easily generate new revenue streams through exciting new services such as home network security while delivering ultimate Wi-Fi performance.

 

As the latest addition to the GigaSpire BLAST family, the GigaSpire BLAST u6x supports multiple access technologies, allowing BSPs to future-proof their subscribers’ networks and protect their investment. The GigaSpire BLAST u6x offers BSPs unique ways to grow their business and excite their subscribers, including:

 

  • Complete flexibility: The swappable optical modules enable BSPs to seamlessly upgrade subscribers’ access technology without having to replace the entire Wi-Fi system (eliminating the need to recreate or re-establish the SSID and other settings), dramatically simplifying the installation process and delivering up to a previously unreachable 10-year lifespan, ensuring the longevity of the system. Furthermore, the lifecycle of every GigaSpire system is future-proofed by enabling new technologies, such as Wi-Fi 6E, through the addition of a low-cost mesh satellite—eliminating the need for BSPs to perform “rip-and-replace” upgrades in the future.
  • Operational simplicity: Because the carrier-class GigaSpire BLAST u6x runs on the Experience Innovation Platform, BSPs that have already deployed other GigaSpire BLAST systems do not need to worry about integrating a new system into their network. This significantly reduces time to market—from months or years to days.
  • Revenue-generating, loyalty-building applications: Like the three other GigaSpire BLAST systems, which are also powered by the Experience Innovation Platform, the GigaSpire BLAST u6x provides a BSP-branded storefront in the subscriber’s home. These services, which are all part of the Revenue EDGE, allow subscribers to benefit from value-added services such as enhanced parental controls, home network security, device protection plans, and the world’s most advanced smart home connected cameras through the Calix partnership with Arlo technologies—all ensuring that the BSP’s brand grows stronger each day.
  • Leading security: The latest integrated hardware security with WPA3 protocols, along with software that is regularly updated and the world’s only deployment of carrier-class physically unclonable functions (PUF), delivers a safe and secure subscriber experience.

GigabitNow, based in the state of Washington, has been a Calix customer for four years, deploying managed Wi-Fi in California, Oregon, Washington, and soon, in Massachusetts. The company has since upgraded to GigaSpire BLAST systems to develop community fiber networks and invested in the rest of the Revenue EDGE solution to excite subscribers with an unmatched experience.

 

“For GigabitNow, the GigaSpire BLAST system has been an excellent choice for our network deployment strategy due to its built-in management features, exceptional coverage, and powerful software platform,” said Dan Sivils, chief operating officer for GigabitNow. “We’re thrilled by the launch of the GigaSpire BLAST u6x, which will allow for easy upgrades to 10G services and fewer systems to install at the subscriber’s location, reducing installation costs—it’s a win for our subscribers and us.”

 

Many Calix customers are choosing to exclusively deploy GigaSpire BLAST systems to their subscribers to put their brand front and center in the home, eliminate the support headaches associated with systems purchased at big-box stores, and increase customer satisfaction—in some cases achieving Net Promoter Scores far above the industry average. As a digital storefront in the subscriber’s home, GigaSpire BLAST systems enable BSPs to craft exceptional subscriber experiences with premium service offerings that drive revenue growth. Like the rest of the GigaSpire BLAST family, the GigaSpire BLAST u6x is tightly integrated with all elements of the Revenue EDGE solution, including Calix Support Cloud, Calix Marketing Cloud, the brandable CommandIQ mobile app, and all Revenue EDGE Suites.

 

“Today’s introduction of the GigaSpire BLAST u6x system sets the standard for the industry—with support for multiple access technologies up to 10 Gbps, the GigaSpire BLAST u6x offers unmatched performance, flexibility and a 10-year lifespan that helps customers protect their investments,” said Shane Eleniak, senior vice president, Revenue EDGE products for Calix. “Nearly all our customers are either expanding, upgrading, or building new fiber networks, and we expect this trend to continue for years. They would like to make these important investments without having to worry about the cost and complexity of replacing the entire Wi-Fi system every time they adopt a new technology.

 

“With the u6x, service providers can start off using GPON technology or Ethernet behind an old DSL system, then seamlessly upgrade to XGS PON when they’re ready,” continued Eleniak. “Or they can offer an industry-leading 10 Gbps service with Calix Intelligent Access Edge right out of the gate, leapfrogging the services offered by competitors. No matter the approach, the GigaSpire BLAST u6x enables BSPs to deploy quickly, without extensive integration cost, and allows them to save on CAPEX and OPEX. With the GigaSpire BLAST u6x, we’re demonstrating the value a BSP of anysize can get by partnering with Calix to create a state-of-the-art, simplified broadband business that excites subscribers, establishes their brand as the market leader, and grows the value of their business for their stakeholders.”

Urban spaces are sprouting up like mushrooms, growing beyond their boundaries and presenting completely new challenges in terms of mobility and infrastructure. Mobility as we know it today, with overcrowded streets and poor air quality, is a model that has had its day.

Climate goals aside, urban transport networks are barely keeping pace with the enormous numbers of commuters who move around each day. If we consider Latin America, with the high altitudes of Bolivia’s capital La Paz or the Mexican metropolises, the models being implemented may well inspire urban future-proof mobility concepts for other cities in the long term: Modern cable car systems that traverse many different city plateaus. From the high altitude regions of the Alps, for example, we are familiar with gondolas and cable car systems that are networked with the latest technology. But what requirements does the network have to meet in urban areas?

Up high in Latin America

© Doppelmayr Seilbahnen GmbH

Mi Teleférico, which translates from Spanish as “my cable car,” has connected the Bolivian cities of La Paz and El Alto since 2014. In this case, the Austrian cable car manufacturer Doppelmayr/Garaventa has built the world’s largest urban cable car network. Consisting of ten lines in total, the cable car network offers daily commuters a faster way to reach their destinations. Some sections of the system negotiate up to 666 meters of difference in altitude. It wouldn’t work without the latest technology: For the security-related applications and additional service offerings for passengers, a stable Wi-Fi® network is essential. The requirements of a Wi-Fi for urban cable cars like those in La Paz are extremely tough. On the one hand, the network has to control safety-related applications, such as the intercom system in the gondolas, security cameras and lighting control, as well as the monitoring of the pylons and battery systems. On the other hand, passengers in the gondola expect Wi-Fi with a strong and stable signal. With travel times of up to half an hour, a seamless Wi-Fi network offers even more convenience.

Networks at the cutting edge

The implementation of a network over a total distance of 30 kilometers required the setup of a communication system consisting of Wi-Fi access points and directional radio antennas. In La Paz, each cable car pylon and each individual gondola is equipped with a dual-radio outdoor Wi-Fi access point. The altitudes involved demand special hardware for the networks. Thanks to their IP66 protective housing, outdoor access points work reliably in temperatures ranging from -33° to +70° Celsius and withstand the weather with its snow, dust and the cold of the Andes. The APs are equipped with directional antennas to specifically focus the Wi-Fi signal along the path taken by the gondolas. Each gondola is also fitted with an AP that receives the signal and forwards it to the Mobility Communications System (MCS)—in this case a central system designed by LOOP21. The central communication system replaces, among other things, the radio technology required for the alarm and safety system. To ensure seamless wireless connectivity for the communication system, it is particularly important that the directional radio antennas of the OAPs are aligned precisely.

Requirements in airy heights

The demands on a network in urban areas are great: it has to handle long distances, extreme differences in altitude, and different sources of interference from radio networks. And the wireless network is just as scalable as the cable car network itself. New sections of a route can be quickly and easily provided with Wi-Fi and integrated into the overall network.

As a model for the mobility of the future, urban cable cars like those in Latin America are a role model for metropolitan regions that are reaching their limits of their infrastructure. Thanks to modern network technology that combines passenger convenience with important security requirements, future viability is guaranteed.

Wireless technology has been around for more than a century, so why does it feel like wireless devices have only become popular in the last few years? Well… one of the main reasons for that is the need to license frequency bands.

Wireless devices communicate with each other and the environment using electromagnetic waves. Whenever two different devices use the same frequency, much like with Wi-Fi, the information each device captures might interfere with the other. In the past, it was common to “rent” or license a frequency to ensure that you are the only one using it and avoid interference. A perfect example is radio stations. Radio studios license a specific frequency to operate within a particular region. If you turn on the radio to your favourite station while being in a different region, it will most likely not be playing that station.

Licensing frequency bands, although sometimes necessary, can become a significant step back for innovation. It drastically limits the number of technologies that can operate under a specific frequency since there is no point in creating a product you will not be allowed to use or sell.

Fortunately, countries have been increasing the number of unlicensed band ranges. For example, several countries have now opened the use of the 6 GHz band. The proliferation of unlicensed bands has allowed many new technologies to emerge, including personal wireless health monitoring devices.

Wireless health monitoring devices

Some wireless health monitoring devices use a millimetre-wave sensor that generally operates between 24 GHz and 77 GHz and can detect micromovements. They can work as following:

  1. The sensor sends out a wave,
  2. The wave bounces off a surface,
  3. The wave comes back to the sensor,
  4. The system then calculates the millimetric position of that surface.

If the next wave the sensor sends out comes back differently, the system can calculate all subtle position changes. Using sophisticated AI algorithms, these devices are tailored to capture living beings’ micromovements and convert that data into three crucial features:

  1. Movement
  2. Breathing rate
  3. Heart rate

It is essential to understand that wireless health monitoring devices do not fully replace wearable devices such as smartwatches or fitness trackers. It is the solution that fills the gaps with current monitoring systems. Let’s go over some of their pros and cons.

Benefits

  • No wearables – Users do not have to wear any device to have their health measured. In comparison, wearable devices require users to wear them even during sleep.
  • Zero maintenance – Wireless health monitoring devices do not need to be recharged, unlike wearable devices that require the user to charge it weekly or even daily. Once the device is set up, the user can leave it running non-stop.
  • Non-intrusive – People do not like being spied on, and rightfully so. These devices do not have any cameras, allowing the user to feel at ease at all times.
  • One sensor, multiple people – Each person can be uniquely identified based on their micro-movements. The wireless device can identify the people within its range and measure their biodata accordingly.

Limitations

  • Static – The sensor is not mobile. Users cannot carry it around like wearable devices.
  • Range Although its range can be seen as a benefit since it has a much more extensive range than wearable devices, current iterations of wireless health monitoring devices have a range of 3 meters, which can sometimes not cover an entire room.
  • Setup – The device may require a longer calibration time before use. The setup is not a significant limitation, but it is essential to go over its aspects.

Potential Use Cases

Sleep Monitoring

Wireless tech is the best solution for sleep monitoring. It can sense the necessary information to measure sleep quality (movement, breathing, heart rate), and it does not provide any discomfort to the user since it is contactless.

Telehealth

Due to the COVID-19 pandemic, up to 40% of American citizens avoid visiting a medical care center for non-COVID-related concerns [1]. This has led to a drastic increase in telehealth appointments. In Canada, 60% of medical visits became virtual in 2020 [2].

Wireless health monitoring devices add another component to online appointments by providing doctors with their patient’s biodata (with the proper. A great use case is a doctor checking their patients’ breathing data throughout the night and quickly spotting any irregularity, such as sleep apnea, affecting 26% of adults in the US [3].

One of NASA’s space suits now has two Wi-Fi clients and three Wi-Fi antennas.

NASA astronaut Kate Rubins wore a Wi-Fi® enabled helmet camera during an extravehicular activity on 28 February 2021 to demonstrate a high-definition live video streaming application. Rubins and NASA astronaut Victor Glover were attaching brackets so that new-technology solar panels could be added to the solar arrays. The crew inside the International Space Station cabin were able to see the video on a laptop, while the support team on the ground also used the video to coach the pair through a grueling procedure that was beleaguered by two stuck bolts and a damaged glove. NASA refers to the camera by a stacked acronym, it is the High Definition Extra-Vehicular Mobility Unit (EMU) Camera Assembly, or HECA.

Although eight access points (APs) now provide service outside of the space station, Rubins and Glover needed to work together at the farthest port-side end of the space station’s main truss. That is presently about 50 meters from the nearest Wi-Fi infrastructure, and the view is blocked by the station’s solar panels and thermal radiator panels. The nearest infrastructure points consist of antennas outside the space station cabled to an AP inside the space station. Despite the challenges of distance, cables, structural blockage, and roaming, the live high-definition video was available during most of the work, and the camera’s client switched quickly between APs as Rubins changed position and orientation.

While the pair were as far from the airlock as an astronaut can climb, pausing for a routine glove check Glover observed a split in the rubbery coating at the left index finger crease of his glove. It appeared to be a small hole. Any damage to the protective layers of the glove could leak oxygen from his suit. Victor struggled to decide how much damage he was seeing.

“When Kate gets over here, maybe I can show you in the HECA.”

“Yep, and that’s exactly what we were thinking, Ike” mission control replied.

After some high-definition inspection under artificial lighting, the Capsule Communicator (CAPCOM) advised Glover, “Ike, I think we have as good a view of that glove as we’re going to get. Just minimize the use of that hand.”

Victor Glover’s standard definition camera did not convey enough detail for the ground to inspect the damage to his glove. (Source: NASA)

After Kate Rubins moved to use her new helmet camera to inspect damage on Victor Glover’s glove, CAPCOM relayed the decision to continue the spacewalk and “just minimize the use of that hand.” (Source: NASA)

A gradual approach to technology transition

The cameras were delivered to the space station in November 2019 to support servicing of theAlpha Magnetic Spectrometer, but instead remained in storage until the crew had time to retrofit the suits with a package of upgrades. In November 2020, the population of the space station more than doubled when the first operational SpaceX Crew Dragon docked with a manifest of four astronauts. And in early February, Rubins assembled a camera, turned it on to make certain it worked, and then installed the first of the cameras onto the “EV1” (red stripes) space suit.

The HECA up-streams live HD video through Wi-Fi for viewing by the crew and on the ground. The HECA HD video is also recorded to internal storage, and segments can be recovered afterward by uploading over Wi-Fi for return-link to the ground.

HD video will help with close-out photo-documentation that recently has been performed using a hand-held Nikon D5 or GoPro video. A ground console operator in the Mission Control Center (MCC) using the call sign “CRONUS” can command the video encoder in the new camera to a wide range of streaming rates. CRONUS can also use the camera to take still photos. The crew inside the space station can now display the video on a laptop to help them track the spacewalk as it progresses, and therefore CRONUS can configure the camera to stream to two destination addresses over wireless so that both the crew and the ground can observe simultaneously.

The camera uses a pair of low-profile circularly polarized antennas that are oriented to achieve omnidirectional aggregate coverage rather than overlapped antenna coverage. Low profile antennas on a suit are less likely to snag or break and are therefore preferred as it is not uncommon for the suit to drift against the structure as the astronauts climb, reach, twist tools, or float through narrow openings. The camera supports Wi-Fi CERTIFIED™ ac, also known as Wi-Fi 5. The Wi-Fi client adapter in the HECA is the first client to support Wi-Fi CERTIFIED LocationTM, opening the possibility that someday ground control teams will be able to plot the spacesuit location during critical operations, or that a future suit informatics system can know its own relative location by using the Wi-Fi infrastructure to gauge distances.

The U.S. space suits already had a Wi-Fi client, an engineering data recorder that debuted in March 2019. The EMU Data Recorder (EDaR) live-streams non-critical low-rate telemetry.

Chris Cassidy modeled the prototype high-definition digital helmet camera (round lens on left), as he rehearsed the Alpha Magnetic Spectrometer servicing EVA in 2019. The camera was part of a larger suit upgrade package that waited over a year on-board the space station for the crew to have time to install. Legacy cameras (square lenses on right) continue to provide standard definition video. (Source: NASA)

NASA has deployed eight mixed-vendor Wi-Fi 4 access points to provide coverage outside of the International Space Station. Other external payloads have been stationary, so the suits are NASA’s first mobile outdoor Wi-Fi clients. Some special engineering is needed to increase the agility of the Wi-Fi connection managed by the cameras as they move outside the space station. The activity allowed NASA to evaluate impacts to the network before adding a camera to the second suit.

Wi-Fi was the obvious choice for the HD suit camera. The existing wireless video infrastructure cannot support digital signaling, and the Intel single-board computer selected to perform video encoding already included a Wi-Fi radio. Wi-Fi coverage surrounding the space station is already good, and additional hardware is ready to install as needed to further improve coverage.

Technology, past and future

There was a time before Wi-Fi. The HD camera retired the widest and least-used view among the three selectable analog National Television System Committee (NTSC) standard definition cameras in the legacy system. These helmet cameras appeared on space suits in December 2000, to support the assembly work for the space station. The radio technology for these legacy cameras derives from a terrestrial design that provided cockpit video for NASCAR races during the 1990s. This system is designed to be supported by three infrastructure points on the space station, each point can support a video stream from one space suit. The HECA demonstration comes as the analog system is approaching “end of life.” In fact, the new camera demonstrated far superior wireless coverage when viewed beside the standard definition camera during the activity because one of the legacy infrastructure points had failed and needed to be replaced. The legacy system will continue to operate as the community works through the technology transition.

Space suit live video greatly improves situational awareness on the ground and on the space station, but it is not considered critical. The Russian Orlan suits do not have a helmet camera of their own, but since 2013 have been outfitted with a GoPro to record video and then upload it to the network after returning inside using interior Wi-Fi. The NASA helmet cameras are sometimes used on the Orlan suits, and the new cameras are expected to appear soon on both NASA suits, and the Russian Orlan suits as well.

The current generation of space suit debuted on the Space Shuttle in 1983. As NASA develops the latest statement in celestial fashion for its next walk on the moon, many updates are being incorporated. Expect the functions that Wi-Fi has helped retrofit onto today’s space suits, to be integrated into the next-generation lunar suit design.

Ontario-based network operator invests in the Revenue EDGE solution to offer its fiber-to-the-home subscribers an exceptional quality of experience that differentiates its brand from the competition and fuels growth

SAN JOSE, CA – April 22, 2021 – Calix, Inc. (NYSE: CALX) today announced that Canadian broadband internet service provider TekSavvy has selected the Revenue EDGE solution to differentiate its brand and service offerings and deliver an exceptional broadband experience to subscribers on its fiber-to-the-home (FTTH) network. A fast-growing and disruptive force in the Canadian market, TekSavvy will grow its value with the introduction of its Home WiFi Pro offering, a premium-level managed Wi-Fi service that leverages the comprehensive capabilities of the Revenue EDGE. Overall, this investment in the Revenue EDGE will enable TekSavvy to boost levels of subscriber satisfaction and support while elevating its brand, further setting it apart from competitors.

 

TekSavvy FTTH subscribers will benefit from the powerful Wi-Fi 6 connectivity of the GigaSpire® BLAST, which they can control through the Home WiFi Pro Mobile App—the service provider’s branded version of the CommandIQ® mobile app. Soon, TekSavvy will also offer subscribers an enhancement to their experience beyond managed Wi-Fi by adding EDGE SuitesProtectIQ for advanced network security and ExperienceIQ for quality-of-service and parental controls. Calix customers have achieved incredible results thanks to their investment in the Revenue EDGE, including 99 percent adoption of premium Wi-Fi services, 74 percent adoption of the CommandIQ mobile app, and nearly 60 percent adoption of the apps in EDGE Suites.

 

“Our decision to go with Calix is aligned with our track record for always acting in the best interest of our subscribers,” said Charlie Burns, chief technology officer for TekSavvy. “With the Revenue EDGE, we can further differentiate ourselves in the market with a combination of deep insights, powerful Wi-Fi, and a mobile app that puts our brand front and center. We will continue to invest heavily in our subscribers’ experience, exciting them with services they want and need and fostering strong relationships that will grow the value of our business for years to come.”

 

For more than two decades, TekSavvy has delivered award-winning telecom services that prioritize the needs of consumers. As a leading provider offering fiber broadband services to the previously underserved area of Chatham-Kent, Ontario, the company has worked tirelessly to bridge the digital divide—and plans to invest an additional $250 million in broadband infrastructure by 2026. In a market defined by a few large players, TekSavvy is the country’s largest independent internet service provider, presenting critical competition and a high-quality alternative for Canadians coast-to-coast.

 

“TekSavvy is a phenomenal example of an industry disruptor—a smart, outspoken, subscriber-first network operator leading the way by embracing industry best practices and cutting-edge offerings,” said Alan Lieff, vice president of sales for Calix. “We need more service providers willing to deploy aggressively and invest in exciting their subscribers.

The word “diversity” is pervasive, especially when it comes to the workplace, but do we fully understand its importance? Yes, diversity is about everyone getting their fair shot – but it’s also a smart business decision. When the talent pool is larger and more diverse, everyone brings unique perspectives and experience to the table. Better solutions are found. Breakthroughs are achieved. Innovation happens. Everyone wins.

The importance of diversity was illustrated clearly for me while working on a group exercise for my MBA. We were “stranded” in the arctic with a list of 20 items to prioritize in order to survive. First, we did the exercise on our own. Then, we repeated the exercise with a group of people with similar genders and ethnicities. In the third round, we completed the same task with a more diverse group. The results spoke for themselves: the more diverse the group, the better the outcome and the much greater chance of survival. Although the example is anecdotal, research supports the results. Companies that are gender, ethnically and culturally diverse are more likely to financially outperform their industry peers.

Anyone working in STEM knows we have a diversity problem, with women particularly underrepresented. According to Statistics Canada, women made up only 34% of STEM bachelor’s degree holders in 2016, and only 23% of science and technology workers among Canadians aged 25 to 64. What amazing ideas, breakthroughs and collaborative opportunities have we missed out on as a result? Conversely, since STEM jobs are at the forefront of innovation with some of the highest salaries, what fulfilling careers have women been missing out on?

This is an area I spend a lot of time thinking about, and, in light of International Women’s Day, I hosted a virtual roundtable for the women I work with at Cognitive Systems. I wanted to get their perspectives as women working in tech and kick off an important conversation that should be an ongoing one – not just something we focus on once a year. We need to hear both the good and the bad, and openly discuss our concerns and experiences, so that we can work together to make things better.

Still Room for Improvement

In our discussion, we talked about representation in school, in recruitment and in the workplace. We agreed that progress has been made in education, with more women than ever pursuing degrees in STEM. Unfortunately, we aren’t yet seeing this translate at the same pace into the working world.

One colleague mentioned an important disconnect, observing that women often only apply for a role if they meet 100% of the job requirements, whereas men are less hesitant to apply even if they meet only some of the criteria. In my experience working in tech and reviewing resumes, I’ve found support for this theory. The smaller number of women applicants tend to meet all job requirements. Of course, qualified men apply as well, but there are a lot more who don’t tick every box.

How can we address this in recruitment, so that more women are encouraged to apply? For starters, we can be more deliberate in the way we word job descriptions and promote flexibility in role requirements to encourage a diverse range of applicants. Hiring for specific skills is certainly important, but hiring someone who is motivated to learn and is a good cultural fit is equally important for success.

Another solution is to make best use of co-op programs. At Cognitive, we provide our co-ops with challenging and meaningful work that advances our corporate goals. During our roundtable, one of our students revealed that Cognitive had exceeded her expectations with respect to how she would be treated and the importance of the work she would do. It was disheartening to hear that she had low expectations, but I’m glad we were able to deliver more. By encouraging more young women to apply for co-op roles and leveraging their strengths, we hope they will be excited to continue a career in STEM.

Something else to think about is that not all positions in our industry need to embody traditional ideas of what a “tech job” should be. A company cannot operate solely based on the hard skills of engineering. Developing an idea, product or service is only one part of the equation – many other roles make important contributions that are essential to organizational success. Shining a brighter light on these roles and the soft skills required to perform them should encourage greater diversity in applicants, and not just women.

What do women love about working in STEM?

By increasing diversity in STEM, we are ultimately driving greater success for everyone, and there are many reasons for women to join these industries. My colleagues who participated in the roundtable had some important takeaways to share:

“I like that my work contributes to new ideas that have never been done before. I also like that I’m constantly learning, especially because the tech field is always improving and innovating.” – Safa

“I like being able to directly contribute to innovation and break new ground. Coming up with solutions to make the world a better and easier place for people makes working in tech feel very meaningful.” – Sarmina

“One of the biggest appeals that people might not think of is the creativity involved, every day presents a new challenge and a new puzzle to solve. I am constantly learning, building upon what I know and forced to use my knowledge to solve new problems that have never been tackled before.” – Emilie

“I love that technology is the cross-road between logical and creative. Knowing how something functions and its limitations and then challenging those to create new and exciting things.” – Katie

A few key pieces of advice for women interested in STEM also emerged from our discussion:

  • Don’t be afraid to fail because it’s just part of the process. Fall down, make mistakes, and move forward unapologetically.
  • There is nothing wrong with asking for help.
  • Look for guidance from other successful women in STEM and don’t be afraid to forge your own path.
  • You don’t necessarily need to be an engineer. There are lots of ways to work in STEM outside of traditional “tech” roles.

For increased diversity and inclusion in the STEM workforce, there’s work to be done. Supporting meaningful co-op placements and ensuring hiring practices encourage applicants with diverse backgrounds are small steps we can take today to ensure even more breakthroughs in our future.

I’ll leave you with one quote from our roundtable that really stood out for me:

“I always had a curiosity about the world around me and was inspired by the endless possibilities that STEM offers. With the tools you develop working in STEM you can do anything. Studying STEM means learning how to learn, how to break down a problem, challenge your own assumptions and think outside of the box. Everything you learn just spawns more questions and feeds the hunger within you to keep learning.” – Emilie
