 While the 900 MHz models and the early 2.4 GHz models operated on one fixed frequency, the later 2.4 GHz cards as well as some 2.4 GHz WavePoint access points had the hardware capacity to operate over ten channels, ranging from 2.412 GHz to 2.484 GHz, with the channels available being determined by the region-specific firmware.For security, WaveLAN used a 16-bit NWID (NetWork ID) field, which yielded 65,536 potential combinations; the radio portion of the device could receive radio traffic tagged with another NWID, but the controller would discard the traffic.DES encryption (56-bit) was an option in some of the ISA and MCA cards and all of the WavePoint access points.
