Cisco Aironet 1140 Series Access PointEnvironmentally Responsible

Efficient power consumption

Only platform to combine the power of

dual radio 802.11n with the efficiency ofstandard, 802.3af Power over Ethernet

Eco-Packs reduce packaging by 50%:

Single easy to open carton for quickerstaging and installation

CD documentation vs printed papersaves over 2200 trees = power to heat65+ homes for 1 year

Turning off radios during off hours cutspower consumption by 50% = saving

thousands of dollars per year. Cisco Take back and Recycle Program

Reduces burden on disposal and landfillfacilities

802.11u Interworking with outside networks

Mostly supports neutralhotspot

Shared WLAN infrastructure provides service to many service

providers

Power efficient client scanning for preferred SPs (Cisco proposal)

Support for unauthenticated emergency call (Cisco proposal)

Media independent handover (802.21) support

Communication of DSCP to COS mapping to client (Cisco proposal)

Server authentication using EAP-TLS to prevent man in themiddleattacks

Recently added support for lightweight network selection

In working group ballot, sponsor ballot 2008, approval 2009

Important to SPs and small hotspot providers

Can extend SP network to much larger footprint
