The upcoming 6G will use frequencies that this Chennai-based company is building

REIO Systems, a Chennai-based company incorporated in July 2023, is developing software-defined radio equipment to meet the demands of the upcoming 6G network. The company's product, a wideband FR3 software-defined radio platform, covers the frequency range of 7 to 24 GHz where much of the 6G work is expected to be concentrated. FR3 sits between the current 6G network frequencies and the very high millimetre-wave bands. The FR3 band offers more bandwidth than low bands without the range issues associated with high bands.

REIO Systems was founded to address the need for such equipment, as researchers designing for 6G require radios that can transmit and receive across bands that current hardware does not reach. The company's directors are Lakshman Bhaskaran and Ravi Teja Devara, and the research ecosystem around IIT Madras has been instrumental in shaping the company.

The company's software-defined radio platform is modular and synchronisable, making it ideal for research purposes where multiple units need to be kept in step. It also allows for scalability from a single unit to multi-node testbeds. REIO Systems' customers include research groups, telecom equipment makers, defence electronics companies, and drone manufacturers. The company emphasizes its cost-effectiveness and open architecture, positioning itself as a competitor to equipment imported largely from abroad.
