Release Notes for Cisco Aironet Access Points and Bridges for Cisco IOS Release 12.4(21a)JA1
OL-20668-01
New Features
Support for 802.11n Performance on 1250 Series Access Points with Standard
802.3af PoE
802.3af PoE
The Cisco Aironet 1250 Series requires 20W of power for optimum performance of 802.11n on both the
2.4- and 5-GHz bands. This feature allows you to configure one radio to operate using 802.3af. This
allows full functionality under 802.3af on one radio while the other radio is disabled. When you
eventually upgrade to a powering solution that provides 20W of power to the access point, you can
configure the second radio so that both radios are fully functional with 2x3 multiple input multiple
output (MIMO) technology.

Antenna support
This feature provides support for the new antenna, AIR-ANT2451NV-R. This low-profile,
omnidirectional antenna features six elements: a set of three antennas for the 2.4-GHz band and a set of
three antennas for the 5-GHz band. Peak gain is 2.5-dBi in the 2.4-GHz band and 3.5-dBi in the 5-GHz
band. This antenna was specifically designed for use with 802.11n access points to optimize
performance.

ClientLink
Cisco ClientLink is an intelligent beamforming technology that directs the RF signal to 802.11a/g
devices to improve performance by 65%, improve coverage by up to 27% percent, and reduce coverage
holes.
devices to improve performance by 65%, improve coverage by up to 27% percent, and reduce coverage
holes.
Cisco ClientLink helps extend the useful life of existing 802.11a/g devices in mixed-client networks. It
is beneficial for organizations that move to 802.11n and want to ensure that all clients on the network,
regardless of type, are guaranteed the bandwidth and throughput they need.
