Radio that transmit dynamic frequency selection (DFS) are in this UNI band

255 MHz wide and spans from 5.470 GHz to 5.725 GHz

Delay spread is too great, data from the reflected signal may interfere with the same data stream from the main signal

Series of bits that are referred to as chips need only 2 MHz of frequency space, the 11 chips will require 22 MHz of frequency carrier space

As many as 9 of the 11 chips can be corrupted, yet the receiving radio will still be able to interpret the sequence and convert them back into a single data bit

Transmits across 52 separate, closely and precisely spaced frequencies, often referred to as subcarriers

In OFDM, a forward error correction (FEC) that allows the receiving system to detect and repair corrupted bits

OFDM uses _______________ and _____________ phase modulation for the lower ODFM data rates

2.4 GHz ISM band, distance between channel centre frequencies

DSSS and HR-DSSS channel width

2.4GHz, distance between non-overlapping channel center frequencies
