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.


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.

5


~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.

2.4 GHz5 GHz


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.

2.4 GHz5 GHz


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
