WiSig Networks, an IIT Hyderabad-incubated company, has opened commercial orders for an India-made 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. WiSig is demonstrating the radio and its complete 5G Standalone solution at Yashobhoomi from October 7 to 10.
The radio has 32 transmit and 32 receive channels and operates on the n78 mid-band frequency. WiSig said other frequency variants are under development. The system supports up to 16 spatial layers for downlink and eight for uplink, according to a company statement.
The device 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 takes place in the network’s distributed unit. WiSig said the technology is intended to address limitations in earlier Open RAN radios, particularly in locations with weaker network coverage.
Massive MIMO, or massive multiple-input multiple-output, uses multiple transmit and receive channels to handle wireless signals. In this device, the 32TR configuration refers to 32 transmit and 32 receive paths. The company’s focus on uplink performance is significant for applications in which users and devices need to send data to the network, including mobile broadband and fixed wireless access.
The radio 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 resulted from years of research in massive MIMO and uplink receiver algorithms at the institute and the company. He said the research received funding from the IIITB COMET Foundation, supported by the Union Department of Science and Technology’s National Mission on Cyber-Physical Systems.
The radio uses Altera Agilex field-programmable gate arrays. Christian Lanzani, general manager for Wireless at Altera, said the company had seen strong operator interest in programmable, uplink-performance-improvement-ready Massive MIMO systems since WiSig unveiled its production MIMO radios at Mobile World Congress 2026.
The commercial-order announcement places the technology at the point where research and demonstrations begin moving towards operator procurement. However, the company has said that bulk shipments are planned for 2027, while the supplied announcement does not specify the operators, order volumes or deployment locations involved.
WiSig’s demonstration at Yashobhoomi will continue through October 10, giving visitors access to the radio and the company’s complete 5G Standalone solution.
