Good Day! If you bought or planning to buy a Wifi Router or any wifi related devices, you might always notice the following:






WIFI b/g/n

So what does WiFi b/g/n/ac/ax means?

It is part of a Standard Specification (IEEE 802) developed by IEEE (Institute of Electrical and Electronics Engineers) which is highly recognized by consumers provider. a/b/g/n/ac refers to the naming convention of protocol, 802.11a, 802.11b and so like. I created a table based on the references on other sites to explained further more.

Protocol Year Released Frequency Max Stream/Speed Rates
802.11b 1999 2.4Ghz ~11 Megabits
802.11g 2003 2.4Ghz ~54 Megabits
802.11n 2009 2.4Ghz / 5Ghz 2.4Ghz: 300Mbps / 5Ghz: 600Mbps
802.11ac 2013 5Ghz 3466.8Mbps  / 1733.2Mbps / 800Mbps
802.11ax 2019 2.4 / 5Ghz / 6Ghz 10.530Gbps / 4.8 Gbps / 2.294 Gbps

Benefits of Latest Wifi Protocol?

If you own a latest gadget or phone and you have latest wifi router with protocol such as 802.11ac or 802.11ac, then you will be beneficial on it, latest protocol provides faster speed rates and has various frequency spectrum selection, unlike in 2.4Ghz (802.11b/g/n) most of the spectrum are taken by other Wifi Router/AP nearby so noise would be very disturbing.

Benefits of Older Phones or Gadgets on Latest Wifi Protocol?

Many user wondering if their older Mobile Phones or Gadget can benefit on latest wifi protocol (ac/ax)?The answer would be No, If you own older phones which was designed for 802.11g or 11n, it might not benefit on latest wifi protocol, hence you will be stuck on the max stream of the chipset of your phone.

Can my 2.4Ghz Gadget or Phone connect to 5Ghz (802.11ac)? 

Answer would be No, they are different spectrum so your gadget or phones might not able to scan and connect on it.
