Why is IEEE 802.11A (5GHz) being recommended for wireless communications instead of 802.11B (2.4GHz) or 802.11G?
Answer – There won’t be any available channels in the 2.4GHz band since the other RoboCup leagues use 802.11B and 802.11G for their wireless communications. There are also several advantages to using 802.11A as compared to 802.11B or 802.11G a). The 802.11A at 5 GHz would appear to have a shorter range (as would be intuitive from the frequency), but it can transmit data at a higher bandwidth (54 Mbps using 802.11A vs. 11Mbps using 802.11B). Although 802.11B appears to have great range (100m), bandwidth at that range drops down precipitously (maybe to 1Mbps). An 802.11A network has been setup at the NIST Arenas and tested within its cluttered environment to yield promising results (transmission rate between 48-54Mbps, 40m away from the access point). b). The 802.11A uses a fundamentally different approach to slicing up the frequency range that may actually work BETTER in complex environments. That is, maintain similar ranges while supporting full bandwidth. The 802.11A was also tested,
