HAPs - High Altitude Platforms
[attachment=25174]
• The purpose of the lecture is to discuss one of
new technologies of broadband access using
stratospheric platforms
• Some analysts claimed in 2004 that the
stratospheric radio was the only known
technology that can comprehensively target and
cover the $53B remote area cellular market in a
cost-effective manner.
Two aspects
• Humanitarian:
– all people should be offered universal access to
information infrastructures
• Economic:
– Wealthy markets are saturated; to keep business
running needed are:
• New services
– E.g. new multimedia wideband interactive applications
• New markets
– E.g. the “poor” market: 85% of the world’s population
– Or nomadic users market: 15% of the population
What is stratospheric radio?
• A way to keep antenna fixed at stratospheric heights
(~20 km) with multiple applications:
– Civilian Telecommunications Fixed & Mobile:
• Broadband data – Multimedia – Interactive
services - Direct broadcasting – Video on demand
– Emergency - etc. …
– Exploration, Environment, Navigation,
Transportation, Military, …
Powering
• Periodical refueling
– Combustion engine (Gasoline)
– Nuclear engine (Thermoelectric)
• Receiving energy from the earth
– Microwaves
– Laser
• Capturing solar energy (day) + fuel cells
(night)
Stratospheric radio family
– HALE: High Altitude Long Endurance
– HAPS: High Altitude Platform Station
– SHARP: Stationary High Altitude Relay
Platform
– SPR: Stratospheric Platform Radio
– “Stratospheric Satellite”
– All at the altitude 15 – 30 km
