WiSig Networks Unveils Advanced 5G Radio Unit to Boost Connectivity
Barcelona, Monday, 2 March 2026.
WiSig unveiled a “Made in India” 5G radio unit today at MWC Barcelona, featuring patented uplink technology that significantly extends network coverage to remote cell edges.
Technical Specifications and Market Debut
Officially launched today, March 2, 2026, at the Mobile World Congress (MWC) in Barcelona, the new 32T32R Massive MIMO Radio Unit (RU) operates within the n78 band (3.3–3.67 GHz) [1]. This hardware is powered by Altera Corporation’s Agilex™ FPGAs, a strategic choice intended to deliver high-performance signal processing while maintaining energy efficiency [1][2]. The unit is currently being demonstrated live at the Altera booth (Hall 3, Booth #3D5Ex), showcasing its capability to support both ULPI Class A and Class B operational modes [1]. This release positions WiSig alongside other major industry players like NEC and MTI, who are also deploying production-ready systems utilizing Altera’s wideband radio architectures [2].
Enhancing Rural and Urban Coverage
The core innovation driving this release is the patented ULPI (Uplink Physical Layer Improvement) technology [1]. In telecommunications, the “uplink”—the signal sent from a user’s device back to the tower—is frequently the bottleneck that limits coverage range, particularly at the “cell edge” where signals are weakest. WiSig’s implementation of ULPI aims to resolve this by significantly boosting uplink performance, a capability previously seen primarily in academic research rather than commercial production [1]. By extending the effective range of the cell, operators can cover larger geographical areas with fewer cell sites, directly reducing the capital expenditure required for deployment [1]. This architecture is specifically engineered to support 5G Fixed Wireless Access (FWA) across India’s diverse telecommunications landscape, bridging gaps in both rural and urban connectivity [1].
Strategic Collaboration and Future Readiness
This launch represents a significant deepening of the collaboration between WiSig Networks and Altera Corporation. Christian Lanzani, General Manager of Wireless at Altera, noted that combining WiSig’s signal processing with Agilex FPGAs enables programmable solutions that push 5G uplink performance to new levels [1]. Beyond the 32T32R unit, this partnership has also facilitated the development of an 8T8R high-power macro cell, further expanding the portfolio of O-RAN compliant solutions [4]. These platforms are designed to be “Made in India,” complying with local manufacturing requirements while targeting the global infrastructure market [1][4].
