Radio Characteristics
The Aironet Client Card uses a radio modulation technique known as
Spread Spectrum Transmission or SST. This modulation technique pro-
vides high data bandwidth and excellent immunity from interference and
multipath effects.
Two versions of the Radio Module are offered which differ in their fre-
quency band of operation:
Aironet PC1200 - 900 MHz band (902 - 928 MHz range).
Aironet PC2200 - 2.4 GHz band (2.400 - 2.485 GHz range).
Data is transmitted over a half-duplex radio channel operating at data
rates up to 860 kb/s (PC1200) and 2 Mb/s (PC2200).
Radio Ranges
The Aironet Client Card Radio Module is used in indoor wireless Radio
Networks. The radio range achieved depends on the following:
Data Bit Rates - Better receiver gain at lower data bit rates
Lower bit rate links have an advantage over higher bit rate links. There
is a decrease in receiver threshold as the radio data rate increases. The
maximum radio range is achieved at the lowest workable data bit rate.
Antenna Type and Placement - Increased range with antenna height
The key to maximizing range indoors is to place the Access Point
antenna above obstacles such as cabinets, shelves, etc. An antenna
mounted on the ceiling provides excellent coverage.
