WGB Wireless Client Support
The WGB wireless client support allows the WGB to retain the connectivity to wireless clients in the
other radio even if it lost its uplink in the current radio.

Point-to-point and Point-to-Multipoint bridging support for 802.11n platforms
The point-to-point and point-to-multipoint bridging is supported on the Cisco Aironet 1040, 1140, 1250
and 1260 Series Access Points (802.11n platforms). The 5 GHz bands support 20- and 40-MHz and the
2.4-GHz bands support 20 MHz.
and 1260 Series Access Points (802.11n platforms). The 5 GHz bands support 20- and 40-MHz and the
2.4-GHz bands support 20 MHz.
The following items are supported for AP1040 and AP1260 bridging:
•
MIMO, short-range bridging (on campus or inter-building bridge deployments), with dipole and
MIMO antennas (line of sight and short range) under 1 Km.
MIMO antennas (line of sight and short range) under 1 Km.
•
20-MHz and 40-MHz 802.11n support.
•
Workgroup bridge (WGB) short-range support.
•
SISO (single-in, single-out), MCS 0-7 and legacy bridge rates (802.11 a/b/g and 802.11n) using one
outdoor antenna.

Note
This is only supported using short range links and is not a replacement for the AP-1240/1300/1400 or
other Bridge products.

The following items are not supported for AP1040 and AP1260 bridging:
•
The distance CLI command; long-range links over 1 Km currently are not supported, so the distance
command is not supported.

Access Points are Transmitting Multicast and Management Frames
Access points running recent Cisco IOS versions are transmitting multicast and management frames at
the highest configured basic rate, and is a situation that could causes reliability problems.
the highest configured basic rate, and is a situation that could causes reliability problems.
Access points running LWAPP or autonomous IOS should transmit multicast and management frames at
the lowest configured basic rate. This is necessary in order to provide for good coverage at the cell's
edge, especially for unacknowledged multicast transmissions where multicast wireless transmissions
may fail to be received.
