Comsat extends IP network wirelessly

A broadband IP satellite networking terminal from Comsat Corp. of Bethesda, Md., can extend WANs without wire lines.

Users can set asymmetrical transmission speeds ranging from 300 Kbps to 4 Mbps. The terminal's IP multicasting ability and bandwidth on demand suit it for applications such as video, database updates and software distribution.
