Full bandwidth for apps, streaming and IoT

Wi-Fi 6 scores in terms of performance, power consumption, roaming, latencies and investment costs. The expansion of the new Internet standard is in full swing.

On the field, the Kansas City Chiefs battle the San Francisco 49ers successfully from one yard line to the next. In the stands of the Hard Rock Stadium in Miami, 62,000 fans follow the action – and at the same time access the WiFi network in the stadium.

70 percent of the spectators used the free internet during the 54th Super Bowl in February 2020 to post pictures and videos on social channels or to let friends participate in the atmosphere in the stadium via messenger. According to the network equipment supplier Extreme Networks, more than 26 terabytes of data were transferred, almost 600 megabytes per end device – and all with conventional WLAN technology. Such a flood of data can quickly push wireless infrastructures to their limits, especially since the amount of data to be transmitted is constantly increasing outside of stadiums or mega-events. Streaming apps and video portals are increasingly in demand – even among mobile users. In addition to social and sports apps, iTunes, Youtube and Spotify were among the most popular apps in the stadium at the Super Bowl.

Performance makes users happy

High performance in web access is now part of everyday life for mobile users, as the Bitkom association found in a study on the future of consumer technologies. This not only puts stadium operators under pressure, but also generally everyone who wants to give their visitors, customers or employees wireless access to high-speed internet. You have to ensure that applications that require high bandwidth can be used smoothly. In addition to streaming and videos, this also includes 4K UHDTV as well as augmented or virtual reality.

In order to satisfy all users, networks with low packet loss and low latency are required. Companies, but also airports, hospitals and government offices or educational institutions such as schools and universities are therefore well advised to modernize their networks and make them more efficient if necessary.

This is where Wi-Fi 6 comes in. At the end of 2019, the Wi-Fi Alliance, an association of more than 300 technology companies such as Apple, Huawei and Microsoft, published the standard Wi-Fi 6 (WLAN-ax). Like the previous Wi-Fi-5 standard (WLAN-ac), Wi-Fi 6 transmits not only the often overcrowded 2.4 GHz band but also in the broader 5 GHz band. In addition, the technology is ready to transmit in the 6 GHz band as soon as this frequency range is released by the Federal Network Agency (BNetzA).

Faster connections ensure that data-driven, extremely power-hungry applications can be used in real time without any disruption. With the new standard, the bandwidth increases enormously according to the manufacturer alliance – theoretically up to 11 gigabits per second. At the same time, Wi-Fi 6 reduces the energy consumption of the end devices.

To ensure that as much of the high bandwidth as possible reaches the users, providers such as Huawei Enterprise have optimized their WLAN technology. In his AirEngine-Wi-Fi-6-
The manufacturer has integrated high-performance 5G technology and artificial intelligence (AI) into products. Compared to earlier models, the new access points not only offer four times the bandwidth, but at the same time four times more users can access the network – without any loss of performance. An intelligent mechanism prioritizes applications (multi-queue), prevents data congestion and reduces network latency from 30 to 10 milliseconds.
