Efficient Use of Space Segment Is Key to Reduced Costs Welcome to the second edition of Paradise Datacom's
UPLINK, an e-mail newsletter dedicated to providing
the SATCOM market with applications-based information
relevant to the interests of both architects and users
of satellite communications systems.
 The worldwide popularity of GSM communications has
encouraged operators to deploy services in most cities
and increasingly into remote areas. In parts of the
world where the terrestrial infrastructure is non-existent,
GSM has enabled telecom services for the first time.
The only practical way to extend GSM services into
these remote locations has been via satellite.
Global communications suppliers are turning to Paradise
Datacom products to support GSM mobile telephony networks
and to reduce their operating costs by making more
efficient use of space segment. In addition to enhanced
spectral efficiency offered by the Paradise modem,
less obvious benefits can be realized by adding a Paradise
block up-converter (BUC) or BUC/booster with FSK intelligence
to reduce the required number of components, cables,
connectors and associated system complexity. Less hardware
means greater reliability and simplified maintenance.
A number of existing GSM network integrators and operators
around the world have already discovered the unique
features of the Paradise P300 and P310 series modems,
establishing them as the modem of choice for operators
who use satellite links to connect major system elements
(MSC, BSC and BTS) of their wireless telephony networks.
Companies such as interWAVE and TECORE manufacture
GSM products, that when combined with Paradise Datacom
modems and RF components, create a network architecture
that is optimized for applications utilizing satellites.
By de-centralizing the MSC, double satellite hopping
can be eliminated resulting in a higher quality of
service. The integration of GSM and satellite technologies
allows operators to expand their services into under-served
markets far more quickly and cost effectively than
could be achieved by using terrestrial architectures.
More information about how Paradise Datacom is supporting
GSM space segment communications is available in a
new Application Note, “Paradise Datacom Connecting
GSM Networks via Satellite.”
The paper offers examples of how satellite links can
be employed to expand network coverage as well as provide
a manageable and cost-effective way of connecting various
network elements in locations where terrestrial microwave
and fiber optic links are not suitable alternatives.
