WiSig Networks designs 5G Open RAN infrastructure, device-side systems and cellular IoT silicon, from the chip to the protocol stack, engineered and proven in India.
Incubated at IIT Hyderabad and backed by India’s multi-ministry R&D ecosystem, we build the radio, the baseband, the device stack and the silicon. That is why they work together rather than merely interoperate.

Navabeam, our 32TR ULPI radio, the 5G base station, NB-IoT silicon and an end-to-end Release 15/16 device stack.

ULPI moves uplink processing into the radio unit. OTFDM rethinks where the reference signal sits in the symbol. Both started as research at IIT Hyderabad.
Our technology
Outdoor sites carrying live traffic across India, from a hospital campus in Hyderabad to a village that had no broadband.
See where it runsThe same radio and baseband are configured differently depending on what the network has to do. Each of these starts from the products above.
Fixed wireless where laying fibre does not pay for itself. Uplink reach decides how many households one site can actually serve.
