Quick Guide to Wireless Standards
There are three main wireless standards,
802.11b = 11MBits/s (The original standard, also known as WiFi)
802.11a = 54MBits/s
802.11g = 54MBits/s
A 802.11b wireless network card can talk to an 802.11g wireless card/access point at 11MBits/s.
A 802.11g wireless network card can talk to an 802.11b wireless card/access point at 11Mbits/s.
A 802.11a wireless network uses a different frequency range to the others and in not compatible with 802.11b and 802.11g.
Many wireless manufacturers now incorporate all three standards into their network hardware, allowing users to roam to any wireless network. (Always check the specification of hardware before purchasing)
Performance of a wireless network depends on the distance the radio signal has to travel.
Short distance gives you the maximum transfer rate, the greater the distance the slower the speed.
If the signal has to travel through walls the performance is also reduced.
802.11b and 802.11g typically have a greater range than 802.11a, but this is dependant on the hardware manufacturer.
Hope this is of help to someone.
