Protocol-based Broadband Networks --

COMSAT today unveiled linkway.IP(TM), the newest addition to the LINKWAY(TM) family of broadband satellite networking products.

The Internet Protocol (IP) based product is designed for Internet Service Providers (ISPs) to connect local Points of Presence (POPs) and for multinational corporations to create Intranets or Extranets, connecting offices over an IP network regionally or globally. linkway.IP is immediately available.

"There is tremendous market demand for IP-based networking solutions," said Dr. Benjamin Pontano, president of COMSAT Laboratories. "linkway.IP provides a new option for the growing number of companies using IP to connect locations around the world."

The ease of use for linkway.IP offers businesses in both urban and remote areas an efficient and cost-effective networking solution in today's IP environment. linkway.IP works with Very Small Aperture Terminal (VSAT) size antennas, typically 1.2 to 1.8 meters in size, that fit on building rooftops. The product operates at data rates between 300 kbps and 4 Mbps and applies asymmetrical connections, ideal for Internet applications. An auto-commissioning feature also makes linkway.IP easy to deploy.

linkway.IP provides transmission of information to many locations simultaneously using a new IP Multicasting feature. The multicasting feature, combined with LINKWAY's unique Bandwidth-on-Demand capability, will benefit customers who typically need to send information to multiple network locations. This new IP-networking product is ideally suited for such applications as video over IP, routine catalog or database updates, inventory management, software distribution, digital publishing and IP content distribution as well as Web caching and related applications.

"With IP Multicasting, a customer can send information fast and efficiently to many destinations, limited only by the number of participants on the network," added Dr. Pontano. "IP Multicasting makes Internet satellite connectivity more efficient than terrestrial solutions in much of the world. linkway.IP is even more cost effective as the number of sites increases."
