Angel's Strategic Partners
The High Altitude Long Operation Network (HALO) can
provide metropolitan broadband wireless services at lower cost, with
increased flexibility and improved quality of service.
In partnership with Angel Technologies Corporation,
Raytheon has developed ground and airborne electronics capable of
providing a record-breaking 52-mbps wireless link between the ground
and Angel's HALO Network testbed aircraft in flight. To send a
100,000-page document over a 28.8 Kbps computer modem takes seven
hours — the HALO Network does the same work in 16 seconds.
The HALO-Proteus aircraft will fly fixed patterns in
the stratosphere (51,000 feet and higher) over major cities, above
commercial airline traffic and adverse weather. With its payload, a
HALO-Proteus aircraft can create a cellular pattern covering an area
that currently requires several hundred cellular towers. With its
large antenna array and network components, the HALO Network can serve
customers throughout an area of thousands of square miles.
Customers will be able to access the HALO Network
unobstructed by buildings and terrain features that affect
ground-based systems, and fill-in coverage when terrestrial
infrastructure is incomplete or missing. In the developing world,
airborne deployment will make wireless telephony services possible. In
developed countries, new broadband data services — including
real-time, high-definition video conferencing; telephone calls;
broadband Internet connections; and large file transfers — can be
accessed at substantially reduced cost and at extremely high speed.
designed the HALO Proteus aircraft owned by Angel Technologies, Inc. This
design will bring major changes
to the specialized area of long-duration high-altitude flight especially for the wireless
communications industry. The inaugural flight of the HALO aircraft, called "The HALO
Proteus," occurred in September 1998. Scaled Composites'
world-renowned designer Burt Rutan. On
October 25 and 27, 2000, the HALO Proteus aircraft
set three unofficial (pending ratification by NAA/FAI) world altitude
records with the Model 281 Proteus aircraft.
The three records were peak altitude (62,786 feet),
sustained altitude in horizontal flight (61,919 feet), and peak
altitude (of 55,878 feet) with a 1000-kg payload.
These altitudes significantly exceeded the existing records in
Class C-1.E, Group III. Takeoff gross weights for the two flights
were 8,962 lb. And 11,319 lb., respectively.
