The Need for 5G WiFi – The Panacea

In the post titled “The Need for 5G WiFi – The Media Challenge”, I suggested that the increasing amount of media content and the explosion of networked devices may make the current generation of Wi-Fi inadequate. Let me expand on that thought a little further here before presenting 5G WiFi as the panacea.

The current (4th) generation of Wi-Fi technology also known as 802.11n has largely been deployed in the 2.4GHz frequency band.  This band has limited capacity and is shared with other non-Wi-Fi gadgets/appliances such as baby monitors, microwave ovens, cordless phones and Bluetooth technology based devices such as headsets, computer wireless keyboards and mice, phones etc.    With the medium being shared amongst all these devices, performance takes the back seat, and more so at the edge of the home.  802.11n also supports 5GHz frequency band – a lot cleaner medium than 2.4GHz, but the industry adoption has been very limited largely due to range limitations.

5G WiFi, based on 802.11ac, is the 5th generation of Wi-Fi technology5G WiFi benefits from the 5GHz frequency band. Further, 5G WiFi innovations focus on the pain points of the prior generations especially around media content consumption.   5G WiFi is 3-4 times faster than 802.11N giving us Gigabit wireless speeds. To put this in perspective, this is better than wired USB2.0 speeds and comparable to Gigabit Ethernet speeds.

These increased speeds are achieved through a combination of support for wider channels up to 160MHz [compared to 40MHz in 802.11n], and higher modulations of up to 256 QAM [compared to 64 QAM in 802.11n].  This makes 5G WiFi an ideal option when synchronizing gadgets wirelessly at wired speeds.    Also, 5G WiFi with its industry-specified beamforming technology provides range benefits that enable whole home coverage for media intensive applications such as streaming of HD content.   Together, these innovations help 5G WiFi address the challenges faced by today’s Wi-Fi network in the face of the media challenge.

In summary, 5G WiFi is exactly what the doctor ordered for the next gen in-home mobility experience!!
