Bangalore: The Bharat Electronics Limited is developing a light-weight, cost-effective software-driven communication radio that can operate on any frequency band.

The software-defined radio, as this device is called, can operate on Very High Frequency, Ultra High Frequency, High Frequency and L-band, which otherwise need different radios.

The radio can also work with any legacy radio.

"It (software-defined radio) will change the way communication is managed in a battlefield situation", said I V Sarma, Director (R&D) of the defence electronics company under the Ministry of Defence.

In these radios, hardware blocks would be replaced by software ones. So, a software will do the job of a hardware Circuit Board.

"A software today can generate a waveform which is equivalent to a modulated signal," Sarma said, adding, "Every hardware element in the radio is getting replaced by a piece of software".

"Entire radio can be designed using quite a lot of software", he said, adding, there will only be hardware to run the software and to amplify power.

BEL, which has supplied close to 2 lakh radios (earlier versions) to the Defence Forces till date, expects to demonstrate the Army-version of the software-defined radio in March and come out with the ones for Air Force and Navy within a year from then.
