Hybrid and Satellite Communication Networks
A special issue to be published in WIRELESS NETWORKS
published in cooperation with the ACM:
Scope: As attention is focused today on wireless communications, a key
component of the wireless connectivity
fabric is often overlooked. Satellites represent a crucial element of
the global information infrastructure and are
experiencing a quiet technology revolution that will multiply their
capabilities significantly. The recent
launches of OLYMPUS in Europe and the ACTS in the United States
have proven that on-board processing,
bandwidth-on-demand, switchable spot-beams, and the use of the Ka-band
can convert, until now, the passive
"bent-pipe" reflectors to powerful, full-fledged network nodes.
The satellite advantages of ubiquitous coverage,
easy access, large bandwidth, immunity to terrestrial catastrophes,
and relatively low-cost add up to make
satellites indispensable as parts of the worldwide information highway.
The much discussed personal communication systems that are currently under
development, from Motorola's
Iridium to the Teledesics bold constellation concept, demonstrate one
aspect of the envisioned role of future
satellite systems in the mobile communication area.
The main technical bottlenecks that must be overcome to permit
the seamless incorporation of satellites into
modern hybrid networks and their transparent interoperability
with terrestrial links (whether wireless or not)
include:
- The mismatch of bandwidth, error-rate, and propagation
delay properties between satellite and terrestrial links.
- The need for seamless network protocol operation
- The differences among the multiple services anticipated by
such networks in the emerging multimedia markets
- The congestion, access, admission control, and bandwidth allocation problems
- The cost of terminal manufacturing with dual (space/terrestrial)
capabilities
- The regulatory, standardization, pricing, and other commercial and business
issues that impact the operation of such systems.
