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 2.4 GHz and 5 GHz 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 5 GHz (5150-5850 MHz) (Revision A, 11a Turbo Mode) ■ Band 2.4 GHz (2400-2483.5 MHz) (Revision B, G, 11g Turbo Mode) Direct Sequence Spread Spectrum ■ CCK, DQPSK, DBPSK (Revision B) ■ OFDM-BPSK, OFDM-QPSK, OFDM- 16QAM, OFDM-64QAM (Revision A, G Turbo Mode) ■ ■ ■ The range of the wireless signal is related to the transmit rate of the wireless communication. Communications at lower transmit range 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 signal path of the radio that may either absorb or reflect the radio signal.
