BEL bags order for Software Defined Radios; Will they be game changers for Indian military?

Bengaluru-based defence public sector undertaking (PSU) Bharat Electronics recently bagged fresh orders worth Rs 732 crores from the Indian armed forces.

This latest haul of orders spans across a wide range of defence equipment and services, including Software Defined Radios, tank sub-systems, communication equipment, missile components, financial management software, cybersecurity solutions, and various upgrades, spares, and services.

Among all these orders, the Software Defined Radios (SDRs) have emerged as the real star of the show.

SDRs aren't just any regular radios being supplied to the armed forces. They represent a significant milestone in India's journey towards self-reliance in defence technology, commonly known as 'Atmanirbhar Bharat' in defence manufacturing.

What makes these SDRs truly special is that they are the first fully indigenous radios that have been jointly designed and developed by BEL in collaboration with the Defence Research and Development Organisation (DRDO).

This partnership between a leading defence PSU and India's premier defence research body has resulted in a product that is entirely homegrown, from concept to production.

The significance of these orders goes beyond just the monetary value. For a country that has traditionally relied heavily on imports for critical defence equipment, having a fully indigenous communication system is a matter of strategic importance. These Software Defined Radios are not being manufactured in some foreign factory under license. They are being designed, developed, and manufactured right here in India, by Indian engineers and technicians, using Indian expertise and know-how.

What is a Software Defined Radio?

So what exactly are Software Defined Radios, and why are they creating such a buzz? “In simple terms, these are next-generation communication devices that use software to perform functions that were traditionally handled by hardware components. Think of them as smartphones compared to old landline phones. The beauty of SDRs lies in their flexibility and adaptability. Unlike conventional radios that are locked into specific frequencies and protocols, these software-based radios can be reprogrammed and updated to work across different communication standards. This means the same radio can talk to multiple types of equipment without needing separate hardware for each,” explained defence and space analyst Girish Linganna.

Globally, several leading defence firms have been developing military SDRs for years. Companies like L3 Harris, BAE Systems, General Dynamics, Thales, and German firm Rohde & Schwarz are among the major international manufacturers producing these advanced systems. Rohde & Schwarz, for instance, has delivered over 1,000 software-defined radios for F-16 aircraft integration, demonstrating proven operational capability in demanding military environments.

“The ongoing Russia-Ukraine conflict has particularly validated the critical importance of secure communications on modern battlefields. Ukrainian forces have regularly targeted Russian soldiers using commercial-grade radios and unsecured cell phones, exposing the fatal vulnerability of inadequate communication security. This real-world battlefield experience has reinforced why militaries worldwide are investing heavily in advanced SDR systems that can resist electronic warfare and jamming attempts while ensuring uninterrupted secure communications,” added Linganna.

One of the most practical advantages of these SDRs is their interoperability with existing and legacy radios currently in use with the Indian Army. This is crucial because the armed forces cannot simply throw away all their existing communication equipment and start from scratch. The new SDRs ensure a smooth transition between old and new technologies, allowing gradual modernisation without disrupting current operations. It's like having a bridge that connects the old and new worlds of military communications.

Defence experts point out that for the Indian Army, these cutting-edge technology radios will be game-changers in the field. They ensure secure, real-time communications, which are absolutely vital in modern warfare. In today's network-centric battlefields, where information flows faster than ever and decisions need to be made in split seconds, having reliable and secure communication can make the difference between victory and defeat. These SDRs will enable our soldiers to communicate seamlessly with each other, coordinate complex operations, and respond swiftly to emerging threats, all while keeping their conversations protected from enemy interception.

For India as a whole, this development carries immense significance. It reduces our dependence on foreign suppliers for critical defence communication equipment. It creates high-skilled jobs for Indian engineers and technicians. It builds our technological capabilities and expertise in advanced defence electronics. Most importantly, it ensures that in times of crisis or conflict, our armed forces won't be dependent on external sources for essential communication equipment or its maintenance and upgrades.
