In tactical communications and networking—especially for contested and electronic warfare environments—several India-led developments showcase this shift towards Atmanirbhar Bharat and future-ready defence networks.
Indigenous Software Defined Radios (SDRs) and National Standards
A foundational pillar of India’s tactical communication enhancement is the indigenous development of Software Defined Radios (SDRs)—a leap from fixed hardware radios to software-driven, flexible communication platforms capable of rapid waveform updates, adaptive modulation, and broad spectrum use. These SDRs are being developed by the Defence Research and Development Organisation (DRDO) and manufactured by Bharat Electronics Limited (BEL). They support tactical requirements such as Mobile Ad hoc Networking (MANET), enabling real-time, secure, and resilient communication across diverse operational theatres.
To ensure interoperability and future scalability, DRDO spearheaded the launch of the Indian Radio Software Architecture (IRSA) Standard 1.0, a unified national framework that defines software interfaces, standardized APIs, and waveform portability across military platforms. This initiative—co-developed with the Integrated Defence Staff and the three services—lays a strategic foundation for SDRs that can communicate seamlessly across Army, Navy, and Air Force systems, and can evolve via software updates rather than costly hardware replacements.
The induction of these SDRs into the Indian Army represents a landmark in defence self-reliance, marking a transition to flexible, secure, and software-centric tactical communications that can better support networked operations and AI integration on the battlefield.
Tactical Communication Systems (TCS) and Battlefield Connectivity
Complementing SDRs, Indian defence electronics firms are advancing indigenous Tactical Communication Systems (TCS) tailored for operational reliability in challenging environments. For example, BEL has unveiled a TCS prototype designed for secure, encrypted voice and data transmission among dispersed units, enhancing command and control even in rugged terrain where conventional communications may falter.
These indigenous systems emphasize secure networking, robust encryption, and integration with existing and future communication architectures—foundational prerequisites for AI-driven network optimisation and electronic warfare resilience.
