Overview
Your UTM-1 wireless appliance features a built-in 802.11b/g access point that is tightly
integrated with the firewall and VPN.
UTM-1 wireless appliances support the latest 802.11g standard (up to 54 Mbps) and are
backwards compatible with the older 802.11b standard (up to 11 Mbps), so that both new
and old adapters of these standards are interoperable. UTM-1 wireless appliances also
support a special Super G mode that allows reaching a throughput of up to 108 Mbps with
Super G compatible stations. For more information on the Super G mode refer to:

UTM-1 wireless appliances transmit in 2.4GHz range, using dual diversity antennas to
increase the range. In addition, UTM-1 appliances support a special extended range (XR)
mode that allows up to three times the range of a regular 802.11g access point. XR
dramatically stretches the performance of a wireless LAN, by enabling long-range
connections. The architecture delivers receive sensitivities of up to 105 dBm, over 20 dB
more than the 802.11 specification. This allows ranges of up to 300 meters indoors, and up
to 1 km (3200 ft) outdoors, with XR-enabled wireless stations (actual range depends on
environment).
