IS-Wireless (Poland) – Secure 5G Networks for Defence and Communications

A Polish deep-tech company is quietly redefining how Europe builds its wireless networks. IS-Wireless, based near Warsaw, has emerged as a key innovator in secure 5G technology, targeting both defence and demanding commercial applications. Founded by wireless engineers and researchers, the company is developing “sovereign” mobile networks – systems built in Europe, free from untrusted foreign components, and hardened for extreme conditions.

IS-Wireless’s mission aligns with Europe’s urgent quest for strategic autonomy in critical communications: reducing reliance on non-allied suppliers and ensuring that connectivity never falters under pressure. Over the past few years, this little-known firm has been proving its worth through live 5G deployments, patents for novel network architectures, and selection for prestigious NATO and EU innovation programs. It is a prime example of how a European startup can contribute to collective security by marrying cutting-edge tech with strategic purpose, intriguing defence planners and telecom leaders alike.

IS-Wireless is a deep-tech startup founded in 2017 in Poland, specializing in open Radio Access Network (Open RAN) technology for 4G/5G networks. The company’s core products – including its LiquidRAN™ 5G network solution – align with European Emerging and Disruptive Technology (EDT) priorities in cyber-resilient communications and AI-driven networking. IS-Wireless directly contributes to European strategic autonomy by offering a European-grown alternative to Chinese 5G providers.

Its Open RAN solutions allow EU and NATO members to replace or avoid dependence on Huawei/ZTE in critical infrastructure, strengthening the European Defence Technological and Industrial Base. The company supports NATO interoperability and multi-domain operations by adhering to open standards (3GPP, ORAN) and demonstrating seamless integration of its networks for land, air, and maritime deployments. IS-Wireless participates in European and transatlantic innovation frameworks – it holds an EU EIC Seal of Excellence and is a member of NATO’s DIANA accelerator program – underscoring its dual-use value.
