Random 802.11n Observances
The 802.11n amendment allows for up to 4x4 MIMO. That's 4 transmitters and 4 receivers working at the same time. Due to cost, nobody is building a 4x4 system. Instead, we're seeing 2x2 on the cheap stuff, 2x3 on the higher-end client radios and the lower-end APs, and 3x3 on the higher-end APs. More transmitters and receivers means better quality: better reception, higher throughput, the works. Always look for 2x3 stations and 3x3 APs whenever possible. Continue reading...
