Lets talk about Wifi 5 Routers and key difference with respect to Wifi 6 Routers
|IEEE 802.11aac standard
|IEEE 802.11ax standard
|Only 5ghz band is used as wifi 5
2.4ghz is separate as N network
|2.4ghz + 5 ghz is integrated into single network so you get both bandwidth and coverage auto optimised
|Uses more battery if connected to 5ghz
|Uses Target Wake Time to connect only when required saving battery
|Less no of device can be connected
|Due to OFDMA 50% more devices can be connected to same spec router
|old N/G devices can be connected as 5ghz AC network is separate.
|All devices need to wifi 6 supported to fully use wifi 6 capability. The moment any old device is connected it starts behaving as separate 2.4ghz and 5ghz wifi 5 network router.
|All wifi 5 Wifi 4 wifi 6 devices can be connected
|Only wifi 6 devices for wifi 6 benefits
|cheaper to setup as only router is needed
|costlier as router along with all clients need to be upgraded
|Bss colouring not supported so congestion is formed if too many networks in same place
|BSS colouring supports helps identify from other networks to reduce congestion
Wifi 5 network is almost end of service. While wifi 6 has been extended to wifi 6E where another 6ghz frequency band has been added to support for multi-gigabits speed over wifi networks.
