Product Name: SPACEWAYTM North America
Product Description
SPACEWAYTM is Hughes next generation broadband satellite network
that will provide high-speed, two-way communications for Internet, data,
voice, video and multimedia applications. The initial contract includes three
Boeing 702 geostationary satellites built by Boeing Satellite Systems, (BSS)
and will operate in the Ka-band spectrum. The first orbital slot is currently
planned for 99 degrees west longitude.
The spacecraft are the next generation in satellite communications
technology, with approximately 5 to 8 times the capacity of today's
satellites. SPACEWAY will enable a full-mesh digital IP network that will
interconnect with a wide variety of end-user equipment and systems such as
personal computers, servers, local area networks, and home networks. This
broadband satellite network will provide a range of innovative applications,
enterprise-wide, throughout North America.

The SPACEWAY satellites feature innovative, on-board digital processors,
packet switching and spot beam technology. Spot beam technology will enable
the satellite to provide services to small terminals, while on-board routers
will enable mesh connectivity; users of the system will be able to directly
communicate with any other user of the system without requiring connection
through a central hub.
Boeing Satellite Systems is the world's leading manufacturer of commercial
communications satellites and a major provider of space systems, satellites
and payloads for national defense, science and environmental applications.
