Mobility is an important part of modern communications, in both commercial and military applications. Radio users require mobility, not a fixed communications terminal, and radios that can move with them and operate reliably, often across multiple frequency bands to reach different groups of users.

Persistent Systems, with its modular radio designs and use of Mobile Ad Hoc Networking (MANET) technology, provides mobile radio solutions that are as effective for humans as for machines. These solutions deliver easily integrated radio links for frequencies in L-band (1350 to 1390 MHz), BAS (2025 to 2150 MHz), S-band (2200 to 2500 MHz), and C-band (4400 to 6000 MHz) ranges.

MANET radio technology was developed with the encouragement of DARPA, hoping to create a radio technology that would allow mobile communication anywhere in the world without relying on fixed communications infrastructure (e.g., cellular radio towers). Persistent Systems has developed several lines of MANET radios suitable for human as well as robotic users, such as the unmanned aerial vehicles (UAVs) increasingly used for defense ISR operations.

Its Wave Relay MANET technology can be scaled to create large networks by using multiple hops with high throughput and minimal latency. MANET radios apply internet-protocol (IP) communications techniques, with each radio appearing much like a relay or switch within the network. The radios can send and receive voice over IP (VoIP), video, and high-speed data under demanding conditions to meet the requirements for military applications; versions of the radio can serve a wide range of human and machine applications.
