Cisco Clean Air

• Provides continual, system-wide discovery without performance impact

• Accurately identifies source, location, and scope of interference

• Takes automatic action to avoid current and future interference, with full history reporting

• Cisco AP 3700/2700 provides complete visibility over 80 MHz 11ac spectrum

Client Link 3.0

• ClientLink uses multiple transmit antennas to focus transmissions in the direction of the client

• In the mixed-client networks, optimizes overall network capacity by helping ensure that 802.11a/n and 802.11ac clients operate at the best possible rates, especially when they are near cell boundaries.

• Client agnostic since Multiple Antennas Design Work for All Clients

256QAM Heat Map: Cisco vs. Competition

ClientLink 3.0 YouTube video:

• http://www.youtube.com/watch?v=0q_shbSpOIA

• ClientLink 3.0 helps the Cisco AP achieve 256 QAM with m9 rate

• Cisco’s 11ac AP has a significant 256 QAM advantage over the competition 11ac AP

• The Test:

Use a MacBook Pro (3ss) and record the data rate in 40+ locations in a cubicle environment while running traffic to the client.

Upgrading to 802.11ac APs - 1:1 or another survey?

Question: If I replace my Access Points with a newer 802.11ac Access Point do I have to resurvey? Is

the spacing the same between 11n and 11ac?

Answer: 11ac builds upon 11n, and cell sizes are similar!

Access Points have always had

similar heat maps – There will

always be slight differences but

the goal is to maintain uniform

coverage with less retries. It is

always a good idea to check

coverage.


Multi-Client Performance Performance

• With 802.11ac, the total bandwidth available to clients is increased to 1.3Gbps, but this is still a shared medium technology.

• An efficient packet scheduler designed for the needs of 802.11ac is needed to keep up with client counts of 60+ per radio.

• Cisco’s AP3700 provides on-radio caching technology which leverages additional RAM for per-client queuing techniques.
