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.

Refer to the sheet "Information to the User" for regulatory information that may apply in your country/region.

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	■ DSSS-CCK, DSSS-DQPSK, DSSS-DBPSK
	(IEEE 802.11b)
Technique
	■ OFDM-BPSK, OFDM-QPSK, OFDM-
	16QAMOFDM-16QAM ( IEEE 802.11a/g)

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.
