I would like to connect 200 company locations in remote Indian districts and
share information. The frequency and load of data is not very heavy.
Please suggest a cost-effective solution for connectivity with which data security
can be maintained. Will the use of VSATs be better than a leased line in this
Thank you for the mail.
It is encouraging to see that your company wants to link 200 nationwide locations
and share information.
You can use a leased line to share data across the major locations and the Head
Office. And you can use VSAT for locations in remote areas. Both leased lines
and VSAT are point-to-point links, and thus secure. VSATs are more expensive
than leased lines, but the reliability may be slightly better.
Locations in smaller towns can use dial-ups to connect to the nearest major
town/location from where the data can be passed along a leased line. In order
to secure a dial-up you can use encrypted mail (digital signatures), or sign
up with an ISP for a VPN and remote login through dial-ups.
We hope this will be of help to you. We wish you all the best for your project.
I read the article 'LAN in the sky', written by Soutiman Das Gupta in the November
2001 issue of Network Magazine. The article was quite interesting and useful
Our company has two units, which are at a distance of 1.5 Km from each other.
We want to deploy connectivity links between the locations. Can you please suggest
a technology, that will suit us most? In one unit we need around 30 network
nodes, and in the second, we need around 10 network nodes.
Can you please suggest some names of agents who can provide us their services
in this regard.

Dear Vinay Kumar,
Thank you for writing to us. We are glad that you found the article interesting

In order to connect the two locations you can use RF technology or VSATs.
RF technology: The radio frequency technology uses a line-of-sight beam and
can offer pretty high throughputs in a reliable manner. Krone offers this solution
VSAT: This satellite communication technology is great for remote areas and
offers high throughput too. However it may work out to be expensive. Comsat
Max, HCL Comnet, and HECL are the popular VSAT service providers in India.
We hope this information helps.
Our company uses static IPs at many locations in India. We want to communicate
between our offices with the use of VoIP technology. Every nationwide location
uses PSTN to dial up into the Internet.
Is it possible to use a VoIP solution? If yes, what are the additional components
required to set up the technology in the organization?

Dear Gautam Ashtekar,
Thank you for writing to us.
It is encouraging to see that you wish to use VoIP technology to communicate
between your company locations.
Companies who use VoIP technology for communication between locations typically
use leased line connectivity. In such a case, deploying a VoIP solution is simple
and very cost-effective.
Since you prefer to use PSTN we suppose you do not exchange very high volume
traffic between locations. In that case you must look at the ROI for using a
Even if the use of leased lines do not seem cost-effective today, you can build
the infrastructure keeping tomorrow's needs in mind.
We wish you all the best for your project.
Cost of VSAT
Refer to the article 'Connectivity: The VSAT way' in the June 2002 issue of
Network Magazine. The article says that the cost of VSAT services has dropped
dramatically in recent months. Can you provide an explanation why the costs
have been driven down?
Thank you for writing to us. We are glad that you found the article interesting.
The cost of VSAT services in India has dropped for a number of reasons.
There is increased competition from leased line providers and DSL providers
like Telcos and ISPs. These companies provide bandwidth at lesser costs, forcing
VSAT providers to rethink their pricing strategies.
These companies are penetrating the rural and remote location markets very fast
in search of new opportunity, and to comply with the government's goal of linking
new ground and achieve development.
With the introduction of K-Band VSAT a couple of years ago, there is more
scope for VSAT service providers to provide more bandwidth in a small spectrum.
This helps keep the VSAT service provider's costs low. The service providers
can pass on this benefit to the customer.
I am a regular reader of Network Magazine and I have received a number of benefits
from the information provided by your magazine. Keep up the good work.
Is it possible to feature the LAN architecture of Hindustan Lever Limited in
your publication? I hope that in future you plan to publish an article on this
Dear Sumeet Sinha,
We are glad that you find Network Magazine useful and informative. We have plans
to feature many new organizations in the magazine and Hindustan Lever Limited
is certainly one of them. However, we cannot give you a definite issue month
right away. As soon as we're ready to feature the company we'll let you know
in advance with a mail.
