Persistent Systems builds mobile networking hardware and software for military, first responder, government, and commercial operators who need communications when standard infrastructure fails or doesn't exist. Founded in 2007 as a two-person operation in Baltimore, the company now manufactures its own gear at scale - a deliberate vertical integration that matters in defense supply chains.
The core technology is MANET (Mobile Ad Hoc Network) architecture. The flagship MPU5 radio is designed to route voice, video, and sensor data across contested and congested environments - urban terrain, mountains, maritime zones, underground - where traditional networks either don't reach or get jammed out. Wave Relay® MANET and Cloud Relay™ are the primary system names. Integration points are explicit: UAVs, UGVs, cameras, sensors, and individual operators all mesh into the same network fabric. The company operates the Wave Relay® Ecosystem, a coalition of hardware and software vendors built around their core technology.
Persistent Systems operates from New York City headquarters and targets the military, first responder, and government sectors directly. The company's stated mission - "Network the battlefield. Connectivity drives mission success" - reflects the threat model: denied or degraded communications environments where mesh networking and decentralized routing become operational requirements, not nice-to-haves.
