Я так делаю. Лучше чтоб у тебя половину полосы попортили, чем всю.
Сигнал/шум выше. Так же? "The 802.11b radio link uses a direct
sequence spread spectrum technique..." Но нас больше интересет:
"The 802.11a and g systems use 64-channel orthogonal frequency
division multiplexing (OFDM). In an OFDM modulation system, the
available radio band is divided into a number of sub-channels and
some of the bits are sent on each. The transmitter encodes the bit
streams on the 64 subcarriers using Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), or one of two levels of Quadrature Amplitude Modulation (16, or 64-QAM). Some of the transmitted information is redundant, so the receiver does not have to receive all of the sub-carriers to reconstruct the information.

T.e. во всех случаях частичное перекрытие лучше, чем полное...
