1.ISM = Industrial, Scientific, and Medical.

2.OFDM = orthogonal frequency-division multiplexing.

3.DQPSK = differential quaternary phase shift keying.

4.DBPSK = differential binary phase shift keying.

5.QAM = quadrature amplitude modulation.

6.CCK = complementary code keying.

7.CSMA/CA = carrier sense multiple access with collision avoidance.

8.ACK = acknowledgement.
