LinkStar VSAT modem

Linkstar VSAT terminal DVB, Channel Master antenna, New Japan Radio

LinkStar™ is the star-based VSAT system for service providers, ISPs, and corporate network managers who are seeking a system based on DVB standards. LinkStar's edge is in its dynamic bandwidth allocation that makes it more efficient and faster than other TDMA systems. Terminals can transmit data to the network hub at speeds up to 1.15 Mbps, with data downloads of up to 60 Mbps, satisfying bandwidth-intensive applications using IP data.

LinkStar offers several benefits:

• The highest return channel rate on the market
• Rate-based operation that increases your data throughput
• Guaranteed information rates for each network location
• Lower-cost terminals because fewer hardware components are needed and volumes increase as markets expand
• DVB standards based for compatibility worldwide

LinkStar can operate over C- or Ku-band frequencies, and is scalable to small or large networks. A Web-based NMS makes it simple to operate and easy to configure.

LinkStar Broadband Applications:

• Internet access
• Digital media streaming
• Videoconferencing
• Distance education
• File transfer
• Multicasting
• Virtual private networks
