Connectivity solution

Dear Soutiman,
We are a printing company located at Noida. We are looking for a point-to-point connectivity solution that can link our different offices in Noida within a radius of 5-10 kilometers. Can you suggest a solution?

Dear Sumit,
The type of connectivity (terrestrial, wireless) and the amount of bandwidth will depend on what applications you plan to run and how often you want to share data between locations. For example, do you use an application that needs real-time data transfer, or can you manage by sharing data two or three times a day?

You can try the following:

  • An ISDN link (16 Kbps, 64 Kbps)
  • A leased line (64 Kbps)
  • A VSAT link
  • RF links

Head Office connectivity

Dear Soutiman,
We are a small company based in Kolkata with offices in different locations in West Bengal and other states. We are working on an ERP solution and need to connect all the nationwide offices to our Head Office. Can you suggest how a small company like ours with limited resources, can deploy reasonably secure and cost-effective connectivity. You can even suggest a consultant who can guide us in this matter.

Dear Anup Sharma,
It's encouraging to see that you plan to use an ERP and need to connect offices in other locations to your HO.
Between your HO and critical offices (i.e. offices which need to share critical business data throughout the day) I suggest an ISDN link or a DSL cable link. VSNL, BSNL, and Dishnet can help. Later you can apply for a 64K or 128K leased line. Between other offices (which do not need to share very critical business data) I suggest dial-up links to begin with. You can use encrypted e-mail with digital signatures to exchange information in almost real-time. When the volume of data increases you can consider an ISDN link.

WLAN for soho

Dear Soutiman,
I read your article on WLANs in the September 2002 issue of Network Magazine. It talks about the current scenario and future of WLAN in the enterprise. But what about the future of Wi-Fi in the SOHO segment? Is India ready for Wi-Fi? The large hotels and big companies are, but what about small offices with 10-15 PCs and homes with 2-3 PCs?

Copperless Network India

Dear Rahul
Here are the reasons why I think WLANs have not picked up in India in the home and SOHO segment.

  • Low awareness
  • Cost comparison between cabling an office and a WiFi alternative
  • Restriction of bandwidth. As more users are served by an access point, the available bandwidth is shared. In a wired LAN, a switch will provide the same LAN bandwidth to all users.

Small companies may have a mindset that 'wireless' is an excessive expense. And most Indian homes do not have more than one PC as yet. A lot of awareness regarding the benefits of the technology and paybacks in the long run is necessary before the technology kicks off well.
