WiSig Networks has completed multi-site PoC validations of its full-stack 5G Open RAN platform — Massive MIMO radio, cloud-native baseband, and standalone core. Following 2.5 years of structured C-DOT qualification testing and 22+ live field sites, the platform is now entering extended operator validation prior to commercial scale deployment.
WiSig Networks builds global-standard 5G Open RAN infrastructure from the ground up — from silicon to system software. Designed and engineered in India, incubated at IIT Hyderabad, and backed by India's multi-ministry R&D ecosystem, we have completed the journey from laboratory research to advanced pre-commercial validation, now preparing for operator-led commercial deployment.
Our portfolio spans the complete 5G Standalone ecosystem: O-RAN compliant Massive MIMO radio units with patented ULPI technology, cloud-native baseband, indigenous 5G core, and India's first NB-IoT system-on-chip. Every product is certified, field-hardened, and engineered for carrier-grade operation.
Channel estimation and equalization performed entirely within the radio unit. Only equalized user data layers traverse the fronthaul — minimizing bandwidth requirements while maximizing cell-edge uplink performance. Optimized for cost-sensitive FWA deployments.
DMRS-based beamforming in O-RU with equalization at O-DU. Both data and reference signals traverse the fronthaul, enabling interference suppression, joint multi-cell coordination, and maximum flexibility for dense urban deployments.
In August 2025, AT&T, Ericsson, and Fujitsu announced the first Open RAN call using ULPI-class technology — a major global milestone. WiSig has built the actual hardware from the ground up: a complete 32T32R Massive MIMO ULPI radio with patented global IP (India + USA), fully compliant with 2025 O-RAN specifications. Engineered to meet global carrier-grade benchmarks and designed to compete with leading international vendors upon commercial rollout.
Flagship O-RU with patented ULPI technology. SU-MIMO and MU-MIMO beamforming with up to 16 spatial layers. Powered by Altera Agilex FPGAs. Production-grade, weatherproof outdoor enclosure.
ULPI-compliant DU-CU baseband platform with indigenous 5G SA core. Fully integrated, jointly optimized, and validated end-to-end through extensive field trials.
Hardened outdoor and indoor CPE terminals optimized for 5G FWA. Pole-mounted with custom software stack. Purpose-built for rural broadband and campus deployments.
Fixed Wireless Access for unserved and underserved areas. ULPI technology extends uplink cell-edge coverage, potentially reducing site density requirements in rural deployment scenarios. Validated in live PoC at Chimnapur village smart classroom.
