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.

Scaled Composites 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' founder is 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.
