One question that keeps persisting with Wifi technology, is what does the A, B, G, and/or N really mean… Â Well, quite simply, it is an identifier of what “model” wireless transmitter you have…
But for the average user, realistically, it’s a starting point on the range of a Wifi installation could have.
- A – indoor 35m (outdoor 120m) Â Â Â Â Speed ~ 20 Mbit/s
- B – indoor 38m (outdoor 140m) Â Â Â Â Speed ~ 5 Mbit/s
- G – indoor 38m (outdoor 140m) Â Â Â Â Speed ~ 22 Mbit/s
- N – indoor ~70m (outdoor ~250m) Â Speed ~ 50-144 Mbit/s
There is very little difference between A, B and G and it is likely that you will find transmitter/receiver quality will play a far bigger role in the range you can actually achieve.
N however, specifically added features that increased the potential range and speed. Â For any new installation, I would suggest Wireless-N technology to be used.
