In the global telecommunications supply chain, building physical cellular base stations is an elite club. For decades, telecom giants like Ericsson, Nokia, and Samsung have dominated public radio access networks (RAN) worldwide. While India became one of the largest mobile data markets on Earth, virtually all underlying macro telecom hardware and baseband silicon relied on foreign design IP. The Sahyadri base station represents an indigenous technical milestone in this space, specifically targeting tactical, private, and localized cellular networks. Before Signaltron built the system hardware, founder Himamshu Khasnis co-founded Signalchip in BLR in 2010 (alongside Rajesh Mundhada) to address the core component of cellular design: silicon. Unveiled in 2019, the Agumbe chipset family was presented as India’s 1st indigenous chipset family for 4G/LTE and 5G NR modems. The portfolio includes the SCBM3412 (a single-chip LTE modem with integrated baseband and RF), the SCBM3404 (a 4×4 LTE baseband chip), the SCRF3402 (an LTE transceiver), and the SCRF4502 (a 2×2 transceiver for 5G NR). Operating as a fabless semiconductor company, Signalchip designed the microarchitecture, baseband signal processing engines, and RF layout in BLR, while contracting commercial foundries overseas for physical wafer fabrication. In 2019, Khasnis set up Signaltron as a system-level venture to build complete field-ready network hardware powered by this silicon. Unlike conventional macro networks that require separate, rack-mounted Baseband Units (BBUs), Remote Radio Heads (RRHs), and external cooling infrastructure, Signaltron integrated these components into an outdoor small-cell enclosure. Weighing 7-8 kg in a ruggedized, IP67-rated weatherproof housing, the Sahyadri 4G Network in a Box consolidates the traditional stack into a compact footprint. Driven by the SCBM3412 SoC for radio frequency and baseband processing, the enclosure executes the integrated NIB software stack, combining the Radio Access Network (RAN) with embedded Evolved Packet Core (EPC) and IP Multimedia Subsystem (IMS) functions on the box. It can be wired into a standard backhaul network / operated in standalone NIB mode, creating a local 4G communication bubble without requiring a live external backhaul link. While the Sahyadri platform demonstrates end to end indigenous design capability, its real world rollouts target specific tactical niches rather than replacing mainstream public macro networks: - The Indian Army procured 20 units of the Sahyadri 4G NIB via the Government e-Marketplace (GeM) following technical field trials. This marked the 1st induction of a complex cellular system running on Indian-designed silicon. - The platform has seen vendor-reported pilot deployments on BSNL's network for off-grid rural connectivity. - Signaltron later claimed Telecommunication Engineering Centre (TEC) type certification for a Sahyadri base station running on Agumbe silicon, highlighting it as a regulatory milestone for a telecom platform driven by an Indian-designed chip. Major multinational vendors continue to supply the vast majority of India's commercial macro-cellular infrastructure. Signaltron's deployment operates as a domestic design-to-box success within private LTE, tactical military communication, and small-cell niches. Bharat is rising. 🙏🙏
