Communications, page 2-3 Options are: • 802.11 b/g-Use only 2.4 GHz band • 802.11a-Use only 5 GHz band • Auto, 802.11b/g preferred over 802.11a (dual band) • Auto, 802.11a preferred over 802.11b/g (dual band) Note The preferred band, if available, will be used at power-on, but the phone may switch to the less preferred 2.4 GHz band, if available, and the preferred band is lost. Once the phone has connected to the less preferred band, it will not scan for the preferred band if the current band is acceptable, and may remain connected to the less preferred band. Scan Mode Restricted Data Rates • Auto, signal strength (RSSI)-Use strongest signal in dual band environment Auto-Always scans when on a call. If idle and signal strength is sufficient, the phone does not scan. Associating to an AP, page 2-10 Continuous-Always scans. Single AP-Only scans at power on or if the AP connection to the network is lost.
