IS-Wireless Tech Stack

OpenRAN-based private 5G/6G for defense and industrial operations

Telecommunications Warsaw | Eindhoven | Tallinn 51–200 employees Founded 2017 Privately Held

IS-Wireless builds LiquidRAN-based private 5G and 6G networks for military and industrial environments where commercial infrastructure fails. The stack is deeply telecommunications-native—O-RAN, 3GPP, LTE/5G protocol stacks, NVIDIA A100 GPUs, and simulation tools (ns-3, USRP, QEMU)—with no cloud-native bloat. Active projects span 6G research, OpenRAN blueprints, and ultra-resilient network deployments; hiring is engineering and research-heavy (10 of 13 tracked roles), signaling a technology-first roadmap focused on protocol implementation and emerging standards rather than sales expansion.

About IS-Wireless

IS-Wireless designs and deploys private 5G and 6G networks optimized for defense and Industry 4.0 use cases—tactical communications, autonomous systems, real-time AR, and mobile command units. Headquartered across Warsaw, Eindhoven, and Tallinn, the company operates at the intersection of OpenRAN standardization and proprietary LiquidRAN technology. The product surface includes radio access network (RAN) architecture, core network components, network orchestration (MANO), and digital twin platforms for planning and optimization. Current pain points center on building ultra-resilient connectivity in resource-constrained environments, rapid base-station recovery, and global customer identification—gaps that reflect both technical and go-to-market maturity.
