Microsoft deploys Lync in Redmond Campus
“The system averaged 16,000 call records over a thirty day period with greater than 96% toll quality, a fifty percent improvement over the legacy network. The network is delivering Lync services as the designers intended, with full fidelity and end-to-end quality of service.” Victoria Poncini, Microsoft’s IT Technology Architect.

2.4 GHz5 GHz
Class room with ~50 students
Clients connect where they want without taking
network conditions into account
1
Often prefer 2.4 GHz which is slower and interference prone
2APs are not evenly
loaded by client count or throughput
4
Clients connect to the strongest RF signal causing some APs to be overwhelmed
3
Individual clients lack information about the entire network and cannot make the best decisions. This results in an inefficient use of spectrum and a negative user experience.
CONFIDENTIAL © Copyright 2012.Aruba Networks, Inc. All rights reserved
Dynamic Environment
Some students break out to do video
research
1
Clients remain stuck to their original AP
2
Break out students SNR drops
significantly
3
Highest bandwidth students are
operating at the lowest data rate
4
As users move, their client often does not adjust. This results in poor throughput, dropped calls, etc. for the user and his neighbors.
2.4 GHz5 GHz
Static students see degraded
performance.

~50 students with ClientMatch
More clients on 5 GHz for better
throughput and performance
1RF utilization and client to AP signal taken into account
when balancing
2
No more slow clients bringing down the
network
3
With knowledge about all of the available APs, their utilization and the clients, ClientMatch optimizes overall network performance for improved scalability and throughput.

Keeping up with a dynamic environment
Some students break out to do video
research
1
ClientMatch adjusts to changing utilization
2
High utilization clients are balanced across APs to limit
bottlenecks
3
ClientMatch continuously updates connections to optimize the network. Clients are steered as network conditions change including high bandwidth utilization and signal changes.

Airtime Fairness
• Maintains application performance in high density areas (e.g., lecture halls) with scheduled channel access time» Works across heterogeneous clients (Broadcom, Intel, Atheros, etc.) » Works across heterogeneous OSs (XP, Vista, Mac OS, etc.)
• Implemented at RF PHY and Layers 4-7• Provides fair access in the presence of mixed-mode
clients in both 2.4GHz and 5GHz spectrums, and across 11b/g/n and 11a/n clients

When to Move to 802.11ac?
Get your network ready first
• PoE+, Gigabit Ethernet for APs
• RF planning when moving from 11abg
• Faster Mobility Controllers
Move from 11abg and continue to invest in 802.11n for now
• 11n is not going away anytime soon
• 11n client devices are here today, 6x the performance of 11abg
• 11n is at the right price point today
