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.

Clients connect to
the strongest RF
signal causing
some APs to be
overwhelmed
Clients connect
where they want
without taking
network conditions
into account
Often prefer 2.4 GHz
which is slower and
interference prone
4
APs are not evenly
loaded by client
count or throughput
2.4 GHz
5 GHz
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.

Some students break

Clients remain stuck
to their original AP

5 GHz
5
Break out students
SNR drops
significantly
Highest bandwidth
students are
operating at the
lowest data rate
Static students see
degraded
performance.
As users move, their client often does not adjust. This results in poor throughput, dropped
calls, etc. for the user and his neighbors.

With knowledge about all of the available APs, their utilization and the clients,
ClientMatch optimizes overall network performance for improved scalability and
throughput.

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
