Cost Effective GSM for Rural Communities in Brazil Using Next Generation Technology

RIO DE JANEIRO, October 21, 2010 - Aroso & De Laurentis and TriaGnoSys have today announced the formation of
a partnership to provide Brazilian telecoms operators and mobile virtual
network operators with a next generation turnkey solution to provide GSM
services to remote communities in Brazil.

The solution, designed by TriaGnoSys and distributed by Aroso & De
Laurentis, uses both satellite and landline connections to provide a complete
GSM service, including voice, data (EDGE) and SMS. It is also upgradeable to
3G and 4G.

Axel Jahn, Managing Director of TriaGnoSys, said, "There are plenty of
places in rural Brazil where telecommunications infrastructures are either
non-existent or very expensive. Examples include remote communities, mining
oil and gas operations, and environmental protection programmes. We are
providing a realistic, cost-effective solution to fill the gaps: the
equipment involved is straightforward to deploy and the costs to operators,
and therefore their customers, are in line with standard market pricing."

The solution is compatible with Brazilian certification requirements and
the hardware, which comes in a compact sealed housing, is quick and simple to
deploy. The software uses highly efficient compression and optimisation
techniques to minimise costs and is easily scalable should demand increase.
The use of remote switching also reduces costs, particularly for calls within
the local area.

A number of antenna options are available, depending on range, capacity
and coverage requirements. The solution also uses a High Power Amplifier to
extend coverage to several kilometres.

Roberto Aroso, President of Aroso & De Laurentis, said, "Modern
communications have a significant positive impact on economic growth. So by
providing more people with more affordable telecommunications, we are both
helping those communities develop and ensuring our long-term role in
supporting that growth. It is a win-win situation."

As well as supplying the equipment, Aroso & De Laurentis also supplies
on-going support and maintenance.

The solution uses ip.access picocells and the Quortus SoftCore network
solution for remote switching. As well as solution integration, TriaGnoSys
supplies the backhaul and remote management software, and world-leading
compression technology.
