Like the businesses it supports, the wireless market is seeing a huge amount of transformation. With each generation, Wi-Fi keeps getting faster. Many factors, and increasing demand, are shaping the market, as new generations and modern technologies enter our workplaces, retail spaces and education systems.
At the centre of this is our demand for constant connectivity wherever we are, and it is not just people. The need for machines to be connected to each other is becoming pervasive in our homes, our places of work and on our streets. We’re seeing countless innovations in areas like the Internet of Things, Smart Cities, data consumption, and an increasing demand for constantly available connectivity. Wi-Fi is the gateway to unlocking this next wave of technology.
Worldwide data and video traffic is growing at double-digit rates, driven by an increase in connected devices. In fact, ABI Research predicts that Wi-Fi device shipments will grow to nearly 35 billion by 2022. Data and video traffic also will surge due to increasing per-device data consumption driven by applications like 4K video streaming, virtual and augmented reality and live-stream gaming.
Thankfully, the industry is starting to solve some of the key problems of the connectivity crunch, and a crucial part of this is something called 802.11ax. This standard helps to mitigate a number of challenges that have affected the Wi-Fi user experience in the past.
Driving more connections, more bandwidth, higher quality
The congestion of people, devices and bandwidth-hungry apps makes for challenges that current wireless tech cannot handle. Adding to the complexity of this environment are diversifying device categories and apps, such as instant messaging, IoT control messages and voice-over-Wi-Fi. CTOs need wireless solutions which can overcome these challenges, whether they’re managing wireless deployments in train stations, or building the next generation of smart cities.
Real-world use cases are bumping up against the limits of existing Wi-Fi standards, and the need for 802.11ax to address a wide variety of heterogeneous, high-density scenarios is clear. Companies which can embrace this technology are setting the stage for converged Wi-Fi, IoT and LTE deployments.
Different from other standards in the past, the new 802.11ax has been conceived not to simply increase the throughput of a single connection, but with the ultimate objective to support high-density connectivity, with the ability to support up to a four-fold capacity increase over its predecessor – critical for locations such as stadiums, public venues, train stations, and schools in which video content and applications are central to the curriculum, are examples.
Real world use cases
Although it is far too early to know what teams will be facing off against each other in the 2022 World Cup, it is almost certain that fans attending the World Cup games will be relying on exceptionally high-quality Wi-Fi to support a wide range of devices, applications and experiences. Stadiums and arenas are increasingly becoming tech-savvy with mobile games, apps, social interaction, AR experiences and contactless payment solutions. They need Wi-Fi to underpin this.
It is important to note that stadiums and arenas are among the most challenging locations for wireless technologies, for Wi-Fi and even worse for cellular solutions, due to extreme high-performance requirements in an ultra-high-density environment. Put simply, basic Wi-Fi struggles when supporting 70K+ fans simultaneously attempting to stream 4K video replays of a winning goal or a missed penalty kick. Fortunately, new Wi-Fi standards such as 802.11ax will help stadiums overcome this by significantly enhancing the fan experience.
Network of the future
CTOs need to ensure they are correctly investing in future-proofed networks. This includes ensuring that their networks are ready for IoT devices, no matter what platform or language the devices use, whether its Bluetooth or Zigbee.
With over 35 billion connected “things” expected by 2022, ensuring quality of service in ultra-high-density deployment scenarios with older standards will become increasingly difficult as content like streaming UHD/4K video becomes common. Customers and partners demand more when it comes to their networks. It’s time for CTOs to look for technology that goes beyond the current state-of-the-art to meet the world’s most demanding network requirements while driving down the cost-per-connection.
Whether you’re in hospitality, education, retail or beyond, Wi-Fi opens doors for you to offer a range of exciting new services and support internal operations. This next generation of Wi-Fi will spur this on. 802.11x brings with it improved high density support, enhanced security, multi-gigabit access speed, and much more than basic Wi-Fi. For true visionaries in the C-Suite, there is scope to go beyond what .11ax offers and tackle the big factors which impact experience. 802.11ax isn’t just a technical standard, it will be an enabler of the smart city, hotel, office network and school and retail environment of the future, not too mention, the network of the future.
