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. Refer to the sheet "Information to the User" for regulatory information that may apply in your country/region. R-F Frequency Modulation Technique ■ Band 2.4GHz (2400~2497 MHz ) for 802.11b/g/n(draft version) ■ Band 5GHz (5150~5850 MHz ) for 802.11a/n (draft version) ■ DSSS-CCK, DSSS-DQPSK, DSSS-DBPSK (IEEE 802.11b) ■ OFDM-BPSK, OFDM-QPSK, OFDM16QAMOFDM-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.
