You might think of WiFi technology as a version of Ethernet without wires in the form of a wireless local area network.
WiFi essentials technology can be used to connect two or more than two devices for various purposes like data sharing. There are no needs of wires to connect with internet or to build a network.
With a strong push from 5G and the Internet of Things (IoT), WiFi has had to evolve in order to keep up with all the technological advances around it. In fact, over the past 20 years, WiFi (also known as IEEE 802.11) has gone from 2 Mbps to over gigabit speeds, a 1000-fold increase in throughput. The standard has continuously advanced itself by introducing new protocols such as 802.11n, 802.11ac and 802.11ax (Wi-Fi 6), the current standard.
The newer WiFi essential standards support a higher order of modulation schemes such as 64 QAM, 256 QAM and 1024 QAM. These standards also support transmission of multiple streams to a single client or multiple clients simultaneously.
In addition to increasing peak data rates, efforts have been made to improve spectral efficiency which characterizes how well the system uses the available spectrum.
The WiFi world is now patiently waiting for yet another incarnation of WiFi, WiFi 7, expected to be available in 2023.
Analysts believe WiFi 7 is to WiFi 6 what 5G is to 4G – an architecture so much more evolved that previous versions are almost like a different technology altogether.
WiFi 7 will improve support for applications that require deterministic latency, high reliability and quality of service (QoS). In the enterprise, this will benefit IoT and IIoT applications, such as industrial automation, surveillance, remote control, AV/VR and other video-based applications.
Also known as the IEEE 802.11be standard, WiFi 7 is expected to provide a max throughput up to 40 Gbps, offer improved cloud gaming and 8K streaming.
Even more important, WiFi 7 will be available to handle technological challenges including 5G IoT and 5G Wi-Fi offloading.
Some of the advances WiFi 7 will offer includes 320 MHz bandwidth and more efficient utilization of non-contiguous spectrum as well as multi-band/multi-channel aggregation and operation.
WiFi 7 will also feature 16 spatial streams and Multiple Input Multiple Output (MIMO) protocols enhancements.
