AirMagnet software surveys Europe's first major 802.11n installation

Dimension Data uses 802.11n WLAN Suite to optimize wireless network

SUNNYVALE, Calif., September 29, 2008 - AirMagnet Inc., the leader in

security, performance and compliance solutions for wireless LANs, today

announced that the company's new 802.11n WLAN Suite has been used for

the first time in Europe by Dimension Data, the specialist IT services

and solutions provider.

Dimension Data employed several of AirMagnet's wireless tools and

software to determine the number and positioning of access points needed

to support an 802.11n network being installed in a new office building

for a large telecoms company based in the UK.

AirMagnet is the preferred wireless assessment tools vendor for

Dimension Data's regional service teams in Europe. The AirMagnet tools

are critical to the planning phase of wireless deployments, where

priority applications such as voice require a predictable and accurate

level of wireless coverage.

Peter Ellis, Network Integration Director, Europe at Dimension Data

explains, "Our client required a solution that included the latest types

of wireless access points to give a high standard of coverage for a

potentially large number of Wi-Fi clients and which would be "future

proof".

Ellis continues "We conducted the assessment in May this year with a

Beta version of 802.11n WLAN Suite. In June, a second assessment

confirmed that the installed network was functioning perfectly, as

predicted. We measured a range of parameters during the site survey

including signal distribution, signal to noise ratio, and speed

distribution. The AirMagnet tools provided this information in graphical

format which we presented in a report back to the client."

"By using the AirMagnet 802.11n (draft 2.0) assessment, we were able to

demonstrate to the client the expected throughput of wireless traffic in

its new premises, as well as the enhanced wireless coverage when

compared with 802.11a, b and g protocols. In addition, we had

transmission rates of around 130Mbit/s compared with 54Mbit/s when using

802.11g."

Ellis went on to say "Where it appears that there may be coverage

problems, we employ AirMagnet's Spectrum Analyser to identify issues

such as RF interference caused by non-802.11 signals such as from

Bluetooth which is often present in office environments."

Since 2005, Dimension Data has conducted various site surveys with

AirMagnet tools, including AirMagnet Survey PRO and AirMagnet Wi-Fi

Analyzer (formerly AirMagnet Laptop Analyzer). "The benefit of adding

the most recent releases to our portfolio has paid dividends for both

the European region and our clients" Ellis concludes.
