Cisco Public 19 Understanding Multipath and Beam-Forming Why you want more receivers and Client Link 2.0 802.11a/g/n 802.11n with multiple transceivers increases fidelity creating a more predictable and reliable performance. AP-3600 is dual band with 8 transceivers (4 per band) that’s two additional radios more then the competition The AP-3600 supports three spatial streams with four transceivers for even greater performance and then adds Client Link 2.0 Client Link 2.0 benefits 802.11a/g/n 1-SS, 2-SS and 3-SS clients Cisco ExpoExpo Cisco BRKEWN-3016 © 2011 Cisco and/or its affiliates.

All rights reserved. Cisco Public 22 AP-3600 – Key takeaways • The extra spatial stream with its additional MCS rates improve reliability and performance allowing faster throughput and more data rates choices to be able to shift to. • Support for extra spatial stream as well as Client Link 2.0 an 802.11n beam-forming method with the FOUR transceivers per band (one more than everyone else) results in less retries and more predictable performance. Net result, it increases the overall data rates @ usable distances maintaining a better link at those top speeds • New Macbook Pro and other devices are coming to market with three spatial streams so the faster throughput with the additional spatial stream is finally gaining meaningful traction in the enterprise. Three spatial streams permit MCS16-23 for up to 450 Mbps throughput Cisco ExpoExpo Cisco © 2011 Cisco and/or its affiliates. All rights reserved. © 2011 Cisco and/or its affiliates.

Interworking Service aids network discovery and selection, enabling information transfer from external networks, and enabling emergency services. It provides information to the STAs about the networks prior to association. • Function: Network discovery and selection (NDS) Generic Advertisement Service (GAS) Access Network Query Protocol (ANQP) Interworking Element Provide lightweight support for network selection GAS provides support for other higher-layer network discovery, service advertisement and mobility management protocols • Status: IEEE 802.11u-2011 is a fully ratified IEEE standard Cisco ExpoExpo Cisco © 2011 Cisco and/or its affiliates.
