tody began shipping its new Wi-Fi transceiver designed to "dramatically" increase the effective signal range of the AirPort and AirPort Extreme Base Stations. The company says the new 27db Transceiver will add up to 1/2 mile line-of-sight. It transmits a more powerful signal as well as uses a LNA (low noise amplifier) to increase the receiver sensitivity. The 27db transceiver operates on all 2.4GHz, Wi-Fi systems. The transceiver is Wi-Fi compliant, supporting both 802.11g and 802.11b and allowing the maximum power output of 500mW allowed by the FCC: Apple wireless products have RF output of 30mW. The product can also be added to any Mac desktop that has Apple's AirPort and AirPort Extreme cards. The $150 kit comes with mounting brackets, adapter cable, wall mounted power supply and (optional) utility software CD.
