Feature Description
Note 1: With respect to T
X power, different (higher/lower) RF output power settings may be used for specific
regions, antennas and/or enclosures, in which case recertification may be required.
2: 802.11n Greenfield is not supported. (Greenfield forces 802.11n operation even in the presence of
802.11b/g AP)
3: Dynamic Frequency Selection (DFS) is supported by the hardware. Firmware support for DFS may not be
in initial firmware releases, but will follow in a later firmware release.
4: 802.11n 20 MHz and 40 MHz bandwidth is supported.
5: The availability of some specific channels and/or operational frequency bands are country dependent and
are firmware programmed at the Host product factory to match the intended destination. The firmware
setting is not accessible to the end user of the Host product.
6: Specifications are based on nominal test settings during module production at room temperature.
