Is moving from a cabled to wireless network a sensible option?
In response to a query on the UKRiders list regarding the downside of wireless networks, Morgan Killick of
ESP Projects, Sheffield and Marcus Pennell of SCIP, Brighton made the following points:
• Do a Wi-Fi survey of the area using NetStumbler (www.netstumbler.com) or similar because Wi-Fi can be
subject to interference/cross-talk from other Wi-Fi transmitters.
• Wi-Fi just isn’t as reliable as cabling because the signal tends to fluctuate and may drop out. This makes
Wi-Fi unsuitable for networking desktop computers, servers and using data intensive applications like a
database.
• 802.11g is half duplex (it can’t send and receive data at the same time); 802.11n can but is more
expensive.
• Wi-Fi signal degenerates through thick brick walls in older buildings and modern pre-stressed concrete in
modern buildings. But Wi-Fi access points can be daisy-chained to extend the signal into difficult areas.
• Consider the security implications of introducing Wi-Fi. WEP security (Wired Equivalent Privacy) is
relatively easy to hack; WPA (Wi-Fi Protected Access) is better than but still not as secure as cable.
• Bear in mind that cabled networks are faster and more robust than wireless networks – this makes them
better suited networking desktop computers, servers and using data intensive applications like a database.

Readers with long memories might recall an article in the Circuit Rider special
issue of Computanews 119/120 in August 2002 entitled ICT support in the
community sector – the “BrisCIT” vision. In the article, Nick Plant of the
University of the West of England described how his students were helping
provide ICT support to the voluntary sector in Bristol. In this follow up, Nick
brings us up to date on the scheme, and lessons learnt.

of key pointers “Planning an ICT
project for a volunteer (or indeed

However, some IT work is best
