Low Capacity Community
GSM Networks
Delivering Affordable, Compact GSM
Solutions to Meet Low Capacity Requirements
Experience shows that traditional high
capacity, large scale wireless networks are too costly
and time consuming to deploy in areas considered too
small, too remote, too low-density or too poor for
cellular services. interWAVE's unique solution enables
GSM network deployment to be viable in these
markets.
interWAVE's portfolio is designed to offer a
low entry cost and highly scaleable solution that
satisfies low capacity coverage requirements using GSM
technology. interWAVE's technology enables operators to
open up new revenue opportunities by quickly and cost
effectively deploying standalone GSM networks in
community areas. interWAVE offers competitive solutions
for start-up network configurations from 100 to 200,000
subscribers. As subscriber demand increases, the initial
deployment can easily expand into a system that is
capable of supporting more subscribers.
A Common Hardware Platform for all GSM
Functionalities
 The core of
interWAVE's GSM solution is our Network-In-A-Box™ (NIB).
The NIB is a fully integrated solution for small
capacity requirements, combining both radio and
switching capabilities in a cabinet that is not much
larger than a standard PC tower. Based on an expandable
architecture, this hardware platform can scale from a
NIB to a network requiring multiple Mobile Switching
Centers (MSC/VLR/HLR), Base Station Controllers (BSC),
and Base Transceiver Stations (BTS). All GSM
functionalities can be either incorporated in a single
cabinet or housed in their own separate
cabinets.
A standard interWAVE's WAVEXpress
configuration (MSC/HLR/VLR, BSC & BTS), as
represented in the diagram below, can support up to 5
BSC, 16 BTS or 30 Transceivers (TRX). It can
inter-operate with existing network infrastructures. Its
standard interfaces allow seamless network integration
to other cellular networks and wireline telephone
networks through ISDN, ISUP, R2 and MAP
interfaces.
During the expansion phases, the initial
investment remains protected. As the network grows
beyond the capacity of a WAVEXpress configuration,
multiple configurations can be incrementally built out
and linked together to form a stand-alone GSM
network.
Key Benefits to the Operator
Because of its unique architecture,
interWAVE's wireless GSM networking solution delivers
unparalleled value and provide the following
benefits:
- Provides low entry cost GSM products.
- Accelerates return on investment: interWAVE's
technology provides operators an incremental "build as
you grow" approach, allowing network growth as
opportunity demands.
- Offers scalability. Operators must be able to
scale their networks to meet constantly changing
demands. The scaling flexibility of interWAVE's
products allows operators to quickly expand their
networks, adapt to market needs (capacity on demand),
and aggressively grow their business, with minimum
financial risk.
- Allows seamless integration to existing wireless
and wireline network infrastructures.
- Allows unmatched speed of deployment and operation
based upon a fully functional compact solution with a
common hardware platform for all GSM functionalities.
Deploying and activating a complete GSM network in an
aggressive timeframe gives operators rapid time to
market - a key advantage where multiple service
providers are competing for the same subscriber base.
- Offers a migration path to GPRS and 3G
technologies.
