Wireless Network Considerations

• The WLAN device supports IEEE802.11a (infrastructure mode only), IEEE802.11b, IEEE802.11g, and
IEEE802.11n.
• The WLAN device operates in the 2.4 GHz ISM band and the 5 GHz lower, middle, and upper UNII bands.
• Microwave ovens may interfere with the operation of WLAN devices since they operate in the same 2.4 GHz
frequency range as IEEE802.11b/g/n devices. Interference by microwaves does not occur with IEEE802.11a
radio which operates in the 5 GHz RF band.
• Wireless devices that transmit in the 2.4 GHz range may interfere with operation of WLAN devices in
IEEE802.11b/g/n modes. Symptoms of interference include reduced throughput, intermittent disconnects, and
many frame errors. It is HIGHLY recommended that these interfering devices be powered off to ensure proper
operation of the WLAN device.

Deactivating/Disconnecting the WLAN Device

Deactivation of the WLAN device may be desired in certain circumstances (to extend battery life) or where certain
environments require it (i.e. hospitals, clinics, airplanes, etc.).

Deactivation Using the Wireless On/Off Switch

The WLAN device can be deactivated quickly and
efficiently by toggling the Wireless On/Off Switch to
the Off position. The Wireless On/Off switch has no
effect on non-Wireless LAN models.
