Overview
Your Nokia IP60 wireless appliance features a built-in 802.11b/g access point that is tightly integrated with
the firewall and VPN.
Nokia IP60 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. Nokia IP60 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: http://www.super-ag.com.
Nokia IP60 wireless appliances transmit in 2.4GHz range, using dual diversity antennas to increase the
range. In addition, IP60 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).
The Primary WLAN
In addition to the LAN and DMZ networks, you can define a wireless internal network called the primary
WLAN (wireless LAN) network. The primary WLAN is the main wireless network, and it controls all other
wireless network's statuses: wireless networks can be enabled only if the primary WLAN is enabled, and
disabling the primary WLAN automatically disables all other wireless network. In addition, all wireless
networks inherit certain settings from the primary WLAN.
You can configure the primary WLAN in either of the following ways:
Wireless Configuration Wizard. Guides you through the primary WLAN setup, step by step.
See Using the Wireless Configuration Wizard on page 194.
Manual configuration. Offers advanced setup options for the primary WLAN.
