Tactical Networking IP Radio Delivering Ultra-High Data Rates!

The Glocom GR-8520VU VHF/UHF High Capacity Data Radio (HCDR) provides ultra-high data rates of up to 5.5Mbps for the transmission of high-resolution voice, video and embedded Blue Force Tracking (BFT) over a truly decentralized mobile ad-hoc network (MANET).

With frequency coverage from 225MHz to 450MHz, the HCDR offers a modular range of configurations geared to match the specific operational requirements of any mission, including vehicle configurations, as well as both airborne and marine radio sets. Featuring an SDR design that supports various waveforms, the HCDR’s wireless resources are dynamically utilized between the network members, providing end-to-end IP connectivity for voice, video and data.

Modern warfare - With its small form-factor, ultra-high bandwidth and advanced capabilities, the HCDR serves as the backbone for secure data network and Ethernet services in the modern battlefield. The solution is ideal for deployed and maneuvering tactical platforms throughout multiple echelons, from brigade level to platoon level.

Vast data distribution - As requirements for data dissemination continue to rise, the HCDR has emerged as a powerful C4I enabler, with capabilities for voice, BFT, IP data and live multicast video. The HCDR expedites military missions by ensuring agile and secured MANET without hindering tactical operations.

Network-centric communications - The HCDR employs advanced algorithms and ultra-high bandwidth to maximize performance throughout the 150-member network.
