WiSig Networks, an IIT Hyderabad-incubated company, has opened commercial orders for an indigenous 32TR Massive MIMO radio designed to improve uplink performance and network coverage, with bulk shipments planned for 2027.
The Hyderabad-based company announced the development at India Mobile Congress 2026 in New Delhi on Thursday. It is demonstrating the radio along with its complete 5G Standalone solution at Yashobhoomi from October 7 to 10.
The radio supports Class A and Class B uplink performance improvement under the O-RAN Alliance’s 7.2x standard. In Class A, received signals are processed within the radio unit. In Class B, the processing is carried out in the network’s distributed unit.
WiSig said the technology is intended to address limitations faced by earlier Open RAN radios, particularly in locations with weaker network coverage. The device has 32 transmit and 32 receive channels and operates on the n78 mid-band frequency. The company said other frequency variants are under development.
The radio supports up to 16 spatial layers for downlink and eight spatial layers for uplink. Massive MIMO systems use multiple transmit and receive channels to manage signals between network equipment and user devices. Uplink performance is particularly relevant to the quality of data sent from devices to the network, including during applications that require sustained uploads or two-way connectivity.
The product was first unveiled at Mobile World Congress in Barcelona in March 2026. It is also part of WiSig’s complete 5G Standalone solution, which the company said has been tested for mobile broadband and fixed wireless access.
Prof. Kiran Kuchi, founder of WiSig Networks and a professor at IIT Hyderabad, said the radio was the result of years of research in massive MIMO and uplink receiver algorithms at IIT Hyderabad and WiSig. According to Kuchi, the research received funding from the IIITB COMET Foundation, supported by the Union Department of Science and Technology’s NM-ICPS mission.
The commercial launch places locally developed radio equipment closer to deployment in operator networks, although the company’s announcement did not identify customers or disclose the value of orders. Commercial availability will also depend on operator procurement and network deployment requirements.
The radio uses Altera Agilex field-programmable gate arrays. Christian Lanzani, general manager, Wireless, at Altera, said the company had seen strong operator interest in programmable, uplink-performance-improvement-ready massive MIMO since WiSig unveiled its production MIMO radios at Mobile World Congress 2026.
WiSig’s demonstration at Yashobhoomi will continue through October 10. The company has indicated that bulk shipments of the 32TR radio are planned for 2027.
