Keep up the Shelf Space section
I am a regular reader of Network Magazine and I enjoy reading it. From its
inception, I have been happy with the variety of topics that are covered in
each issue. In the past, I have benefited on several occasions by reading the
neutral and in-depth analyses of various technologies and products.
This time I thought I should let you know about the benefits we derived by reading
the Shelf Space section of the magazines July 2005 issue. The coverage
of WatchGuard Technologies Incs Firebox X Peak range of products and Allied
Telesyns AT-ARW256E wireless bridge/router were especially significant
Our company has been able to take advantage of the content, and we want to congratulate
your editorial team for providing such insightful information.

A wireless cyber cafe
I regularly read Network Magazine, and find the information interesting and
useful. One of my friends wants to set up a cyber cafe with seven PCs and wants
to use wireless technology to connect the PCs.
Can you tell me about the equipment needed?
Dear Vivek Pant,
Here are a few suggestions for your friend:
- Use wireless network adapters on every PC.
- Use a single 802.11x access point at a strategic
location in the room.
- Use a broadband link with facilities for failover.
802.11b provides 11 Mbps shared bandwidth, while 802.11g provides up to 54 Mbps.
For plain vanilla Internet access, 11 Mbps of shared bandwidth for seven PCs
should be enough.
Wireless LAN equipment is available from vendors such as Cisco, D-Link, 3Com
Visiting the nearest computer product reseller or posting a request directly
to the company's Web site would be a good way to start.
A little SIP for better business
I read Network Magazine regularly, and find the articles related to VoIP communications,
which you publish from time to time, quite interesting.
Our organisation has offices in multiple locations across the country. All the
locations have connectivity links through multiple ISPs. There are, however,
no dedicated links present between the head office and branch offices.
I want to set up an infrastructure that will help me reduce the cost of communication
between the various offices of my organisation. I wish to install a Session
Initiation Protocol (SIP) server and use it to communicate between the office
locations without using a PSTN line.
This will be purely an intra-office communication infrastructure. Can you t
ell me if this is legally allowed in India?
It is legal to use VoIP communications between a Closed User Group (CUG). However,
it is important to ensure that the locations in the CUG are registered offices
of the same organisation.
You can choose between the various VoIP protocols that are currently in use,
but ensure that your router supports the protocol as well. Contact the manufacturer
for any hardware plug-ins and technical support.
We also suggest that you contact a consultant who can study your systems and
provide you with more information on the legalities of it.
