What Sigma Wireless Technologies does

Sigma Wireless Communications Ltd is a Dublin-headquartered mission-critical communications systems integrator founded in 1991, serving enterprise and government customers across Ireland, the UK, and broader Europe. Following a 2025 merger with US-based Day Wireless Systems, the company operates as a wholly-owned subsidiary within the DWS portfolio, combining local European domain expertise with DWS's 55+ years of global resources. The business holds ISO 9001, ISO 14001, and ISO 27001 certifications, with offices in Dublin and Cork.

The company's product portfolio spans analogue and digital two-way radio, DMR/PMR systems, TETRA digital radio, body-worn cameras with push-to-talk over cellular, CCTV with video analytics, thermal imaging, microwave radio, SCADA, off-air repeaters, distributed antenna systems (DAS), voice recording systems, lone worker solutions, cellular paging, FRMCS (Future Railway Mobile Communications based on 5G), and national 4G/LTE private mobile networks. Technology is largely delivered through tier-one partnerships with Nokia (5G, FRMCS, private LTE), Motorola (MOTOTRBO), Jotron (Ricochet voice recording), TRBOnet (lone worker and control room), and DAS specialists Axel Wireless, Stella Doradus, and idDAS. Named reference customers include ESB Networks (national 4G/LTE private mobile network with Nokia), the Irish Aviation Authority (air traffic control tower), HSE (private 5G for digital transformation), and TETRA Ireland.

The business generates revenue through a combination of enterprise and government system sales, professional services for design and installation, and recurring maintenance contracts. Pricing is quote-based and tailored to deployment complexity, typically structured as multi-year contracts. The go-to-market is direct enterprise and government sales with sector-specific engagement targeting public safety, defence, aviation, maritime, utilities, rail, healthcare, data centres, and industrial verticals. The company does not publicly disclose revenue, and growth signals are anchored in post-merger geographic expansion, new product introductions, and active hiring rather than disclosed financial metrics.
