Wireless LAN
Radio Characteristics
Radio Characteristics of Wireless LAN Cards may vary according to:
■ Country/region where the product was purchased
■ Type of product
Wireless communication is often subject to local radio regulations.
Although Wireless LAN wireless networking products have been designed
for operation in the license-free 2.4GHz and 5GHz band, local radio
regulations may impose a number of limitations to the use of wireless
communication equipment.
The range of the wireless signal is related to the transmit rate of the
wireless communication device. Communications at a lower transmission
rate may travel larger distances.
■ The range of your wireless devices can be affected when the antennas
are placed near metal surfaces and solid high-density materials.
■ Range is also impacted due to “obstacles” in the path of the
transmission that may either absorb or reflect the radio signal.
R-F Frequency ■ Band 2.4GHz (2400~2497 MHz ) for
802.11b/g/n (draft version)
■ Band 5GHz (5150~5850 MHz ) for 802.11a/n
(draft version)
Modulation Technique ■ DSSS-CCK, DSSS-DQPSK, DSSS-DBPSK
(IEEE 802.11b)
■ OFDM-BPSK, OFDM-QPSK, OFDM-
16QAMOFDM-16QAM ( IEEE 802.11a/g)
