ViaSat and Verso Complete Interoperability Tests; LinkStar VSATs, Verso NetPerformer Offer Efficient and Cost-Effective GSM Satellite Backhaul

Share Article

ViaSat, Inc. (NASDAQ:VSAT) and Verso Technologies have successfully tested a satellite backhaul system for GSM mobile communications that can cut the cost of GSM backhaul through more efficient use of satellite bandwidth. The system combines ViaSat LinkStar(R) satellite communications networking and Verso NetPerformer(R) technology. The satellite GSM backhaul system was successfully tested in a GSM network in Papua New Guinea for Telikom PNG Ltd. Following the successful trial, Telikom PNG is planning to roll out 50 GSM over satellite remote sites throughout Papua New Guinea.

The system packetizes network traffic and dynamically assigns bandwidth based on voice and signaling volumes. Satellite backhaul links have traditionally used a fixed amount of bandwidth in an always-on mode whether traffic is flowing or not. GSM operators using the ViaSat/Verso system can now cost-effectively expand their coverage to broader service areas where terrestrial or satellite backhaul was not economical before.

The new backhaul system uses ViaSat LinkStar MF-TDMA satellite communications technology that includes advanced bandwidth allocation techniques to assign satellite bandwidth on-demand and Quality of Service features that prioritize calls and data traffic. Bandwidth allocation reduces bandwidth requirements by enabling several backhaul circuits to share a smaller pool of bandwidth. Verso NetPerformer converts the GSM traffic to an efficient IP packet-based format, reducing bandwidth requirements by as much as 50% without affecting call voice quality. In addition, Verso NetPerformer IP routing and acceleration, and legacy voice and data compression enables new services such as Wi-Fi/WiMAX hotspots to share the same network infrastructure.

Incorporating the latest DVB-S2 waveform, LinkStar(S2) VSATs offer up to 30% greater bandwidth efficiency - substantially reducing network operating costs. ViaSat also includes an S2 receiver in its LinkWay(S2) mesh-architecture remote terminals, so customers can integrate both types of terminals into the same S2-capable LinkStar hub system, enabling powerful and flexible hybrid star/mesh network architectures.
