6 05 2008The mask requires that the signal be attenuated by dB, it is often assumed that the energy of the channel extends no further than these limits. Updating is the responsibility of task group For example IEEE 802. 11a and IEEE 802. 11b. The family includes overtheair modulation techniques that use the same basic protocol.

Due to the nearfar problem transmitter can impact receiver on nonoverlapping channel, but only if it is close to the victim receiver within meter or operating above allowed power levels. IEEE THE WLAN STANDARD was original Mbits and Mbits, GHz RF and IR standard 1997, all the others listed below are Amendments to this standard, except for Recommended Practices 802. 11F and 802. 11T. IEEE 802.
One consequence is that stations can only use every fourth or fifth channel without overlap, typically 1, and in the Americas, 1, 5, and in Europe, etc. other European countries are almost as liberal as Japan, disallowing only channel 14, while North America and some Central and South American countries further disallow and July 2007IEEE 802. 11k Radio resource measurement enhancements 2008IEEE 802. 11l reserved and will not be used, can be confused with 802.
