I would like to know how long it would take to get a
broadband connection for our existing office at Aranari,
Perambalur District, which is about 300km south of Chennai.
Our existing office at the above location already has
a 56K modem connected to a phone line and we have Internet
We also need a broadband connection for faster Internet
access to access our servers in Melbourne, Australia.
Dear Siva Kumar,
Joyjit Chatterjee of Comsat Max has responded to your
query. It's as follows:
It is possible today to provide Internet access anywhere
across the country on a VSAT-based system. The solution
involves installing at the client location a terminal
which comprises a 1.2 meter antenna and associated electronics.
The indoor electronic unit has full routing capabilities
and connects to a single PC or LAN.
The traffic to and from the client location is carried
on a satellite link to our Master Earth Station in New
Delhi which has a thick pipe to the Internet through
VSNL on fiber. We have multiple gateways and offer guaranteed
access to the Net equivalent to or better than 99.5
percent of the time calculated annually.
The advantages of accessing the Internet using VSAT
are, anywhere and anytime availability, high uptime,
and consistent performance. On a dialup link especially
in remote locations, it's impossible to predict how
the last mile would behave. Chances are that the maximum
speed would be 19.2 Kbps or lower, even though the modem
can support a higher capacity.
The costs are as follows:
1. A one time expenditure which includes supply of the
VSAT equipment at site, installation, integration with
client equipment, and activation of the link: Rs 1,35,000/-
Taxes are extra on actual.
64K Internet Bandwidth (1:4 Compression): Rs 2,30,000/-
128K Internet Bandwidth (1:4 Compression): Rs 3,85,000/-
Service tax extra on actual.
It should be possible to activate the link within two
weeks. The most time is consumed by the transportation
of equipment from Mumbai.
VSAT at my institute
I read your article 'Connectivity: The VSAT way' in
the June 2002 issue. The article was very informative
convinced me about the utility of the technology. I
need help from you to make a decision.
I work in an educational institute in Himachal Pradesh.
We have around 70 desktop computers linked through a
LAN in the institute. We want to provide high-speed
Internet connectivity to each desktop for the benefit
of our students.
Please suggest the appropriate connectivity and access
technology for the link. How much bandwidth do you think
I should commission? Do I need to install additional
hardware at my premises, if yes, what will the expense
Dr. R.C. Sharma
Dear Dr R.C. Sharma,
You can get in touch with the VSAT Service Providers
in your city if they have an office in your city, or
in the nearest Metro, New Delhi. As an alternative you
can look for telecom providers for leased line access.
VSAT deployment needs you to install receivers at your
premises. VSATs may have high initial cost but is very
flexible and does not suffer any of the downtime-related
problems of a land line. A leased line is a possible
alternative, in which case you may need to install a
leased line modem/receiver at your premises.
The amount of bandwidth you need will depend on the
capacity and budget. A rough estimate for the 70 workstations
is a fractional T1 line.
Concerned about Internet security
I congratulate you on your informative article on the
different ways to access the Internet. I'll be subscribing
to Internet connectivity from Hathway soon, but have
received reports from users of this service that they
have problems with security.
The users claim that others on the LAN can access their
PCs. If I disable file and printer sharing (in Windows)
and use a firewall like Zonealarm, will my PC be secure,
and will I still be able to access the Internet? What
steps do I need to take to ensure security? Is there
any firewall you recommend for my Windows 98-based PC?
As you are aware, accessing the Internet through cable
presents a string of security hazards. With an always-on
connection like cable you have a static (fixed) IP address.
So if a hacker or some malicious program gets your IP
address, it becomes easy to target your computer.
Since you are an individual (not a corporate user),
the onus to secure your PC is entirely yours. But here
are a few precautions to take:
Install a personal firewall software and configure
Install anti-virus software and update the virus definitions
Disable file and printer sharing in Windows
Set the Internet Security level to medium or high
in Internet Explorer
Whenever Windows offers to save passwords, click 'No'
Clear your Cookies and Temporary Internet Folders
after each surfing session
Don't store sensitive information like credit card
numbers on your PC
There are several personal firewall and antivirus packages
available. Although it's against our editorial policy
to recommend products in this column, my advice to you
is, ask around and go in for a popular product. Ask
about the support offered and the subscriptions program.
This is necessary for keeping your software updated.

I read your article on WLAN Implementations in India,
in the September 2002 issue of Network Magazine. In
countries other than India, one does not require government
approval to use 802.11b WLAN radios, since these utilize
the 2.4GHz unlicensed band of the spectrum.
Around July this year, the Indian government considered
deregulation of indoor use of WLAN equipment based on
the IEEE 802.11b standard. Can you update me on the
latest developments towards deregulation in India? Is
there any source I could go to for checking the exact
Mahesh P. Bhave
The Indian government is yet to pass a resolution on
this. When this does happen, one will not need a license
for setting up an 802.11b WLAN within the same building.
So corporate offices will benefit from this.
Following that, there will be a move to deregulate outdoor
use of 802.11b WLANs, but that is expected next year.
To quote Pramod Mahajan, India's Communications and
Information Technology Minister, "The Indian government
has moved to deregulate indoor use of WLAN equipment
based on IEEE 802.11b standards. A plan to deregulate
outdoor use of 802.11b WLANs is also in the works, but
may take until the end of the year to complete. Also
expected is further deregulation of licensing rules
for the 2.4-GHz spectrum."
