Cisco Cisco Aironet 1250 Series Access Point 정보 가이드
“With more and more education-related apps coming in, we believe this functionality
has to be migrated to the wireless network, so our students can make use of it at no
extra charge,” says Martin van der Walle, team networking and telephony manager at
Tilburg University. “We also have to be prepared for the future, where large numbers
of students in large classrooms use their mobile device to participate in lectures.”

Solution
Having reviewed potential solutions, the university chose the newest Cisco wireless
solution, just after the technology was announced. The university thus became the
very first European organization to implement the solution, either within the academic
community or outside it.

Based on the latest 802.11n wireless local area networking standard, the Cisco
Aironet® 3600 access points offer 4x4 radio links, enabling three spatial streams,
and are equipped with Client Link 2.0 for fast Internet connections. The solution also
brings the unique benefits of Cisco CleanAir™ technology, an innovative solution to
the difficulties faced by many wireless network operators in resolving interference
issues quickly.

Cisco® CleanAir technology provides continual, system wide discovery without
affecting performance. Its built-in self-healing capability accurately identifies the
source and location of radio interference, and takes automatic action to avoid
disruption. The new access points were coupled with the flexibility and high
scalability of new Cisco CT-5500 Series Wireless Controllers. “Cisco has very
sophisticated wireless access points with a specially developed chipset,” says van
der Walle. “The latest Cisco CleanAir technology with network self-healing means
more data throughput, along with multicast capabilities too. This is supplemented by
full management, reporting, and analytical facilities.”

After calling in a Cisco systems integrator to conduct a spectrum analysis across
the campus, Tilburg began implementing the solution early in 2012. It started
by replacing 350 existing access points before adding a further 150, mainly in
classrooms and other areas with a high user density. The longer-term aim is to shift
users from the 2.4 GHz waveband to 5 GHz, where the ICT team anticipates being
able to create more nonoverlapping channels.

Results
The Cisco solution is bringing benefits to users, both staff and students, and to
the Tilburg network team. Cisco CleanAir technology and its network self-healing
mechanism are especially useful when looking for sources of interference somewhere
on the campus, which until now had been a costly and time-consuming exercise.
the Tilburg network team. Cisco CleanAir technology and its network self-healing
mechanism are especially useful when looking for sources of interference somewhere
on the campus, which until now had been a costly and time-consuming exercise.
“For instance, we have equipment in some buildings that produces low-level
microwave radiation, which disturbs the wireless signal in surrounding rooms,” says
Broos. “It’s easier to pinpoint the exact nature of a problem when users complain
of intermittent connectivity. CleanAir makes it possible to work around the source
of interference, so it costs us less time to find out where the interference is located
and how to prevent it.” Tilburg University will also achieve more cost savings by
helping enable voice over IP (VoIP) on smart phones or laptops equipped with
soft phones. Downloading Session Initiation Protocol (SIP) software to such end
user devices will allow calls to be made over the university’s infrastructure rather
than mobile networks.
