Caselet Rural Broadband: BSNL Pushes for Common
Wireless Network

B reaching broadband services in rural areas.
harat Sanchar Nigam Ltd has proposed setting up a common wireless network for

The public sector company has suggested that instead of multiple operators setting up a
parallel network, a single network should be set up with support from the Universal
Services Obligation funds.
BSNL’s proposal comes at a time when the Department of Telecom is all set to launch a
scheme to support operators for setting up broadband infrastructure through subsidy
from the USO fund. Under this scheme, two operators will be selected in each circle
through a bidding process.

“The cost of setting up parallel infrastructure by two operators in rural areas shall be
wastage of national resources. It would be better that only one operator is allowed to roll
out the network in rural areas and other operators may use the same network for providing
services in these areas through the Mobile Virtual Network Operator (MVNO) model,”
BSNL has told DoT.
BSNL’s suggestion is similar to the National Optic Fibre Network (NOFN) project being
undertaken by the Government to create a pan-India wired broadband infrastructure. The
Rs 20,000-crore NOFN will be laid by BSNL and the management will be entrusted to a
Special Purpose Vehicle. All the other operators will be able to use this wired network to
reach broadband services to rural areas.
Meanwhile, the Minister for Communications and Information Technology, Mr Kapil
Sibal, on Monday said the proposed national optic-fibre cable network should not be used
by private operators to push their own services but to offer products that benefit the
society at large.
Rural Teledensity
Addressing the curtain raiser conference of ‘India Telecom 2011: m-Powering India’, Mr
Sibal said, “The fact that rural teledensity stands at 36 per cent against the urban teledensity
of 163 per cent shows that the telecom revolution has not reached the people who really
need to be benefited. It should be our endeavour to ensure that this revolution is completed
in an equitable manner.”

11.6 Summary

 WML uses WMLScript to run simple code on the client. WMLScript is a light JavaScript
language.
 WML scripts are not embedded in the WML pages and they need to be compiled into byte
code on a server before they can run in a WAP browser. WML Script is inherited from
JavaScript 1.1 and ECMA Script, Modeled for limited capacity devices, Procedural rather
than object oriented, Uses 32 bit integer.
 WML Script resides within the high-level applications layer of the WAP structure and
adds capabilities for swifter, more advanced and interactive logical operations between
the mobile device and server.
