Nortel Wireless Mesh Boosts Broadband for Patmos Islanders

PATMOS, GREECE, Jul 23 (MARKET WIRE) --
The 3,000 plus islanders of Patmos and its thousands of visitors will
soon have the convenience of island-wide free mobile networking delivered
by joint venture Uni Nortel using a Nortel(1) (TSX: NT)(NYSE: NT)
wireless mesh solution. Uni Nortel is a joint venture in Greece between
Nortel and Unisystems, an IT company and leading Systems Integrator.

Patmos, located in the Dodecanese chain of islands in the Aegean Sea, is
a global tourist magnet. The monastery of St. John the Theologian founded
in 1088 is located on the island and is a place of pilgrimage and Greek
Orthodox learning.

The Nortel wireless mesh solution for Patmos - jointly developed in the
Media Lab of MIT and the Nortel Solutions Interoperability Laboratory in
North Carolina - will be launched this summer to provide wireless
broadband and Internet access services across the island. The network
includes user-friendly hotzones and indoor Wi-Fi, all delivered with
minimal capital expense using Nortel's affordable mesh technology.

The Patmos wirefree project was initiated under the leadership of
Nicholas Negroponte, co-founder and former chairman of the MIT Media Lab,
and Michail Bletsas while both were at the Lab. The project is being
implemented by local Internet Service Provider (ISP) 12Net working with
Uni Nortel which is responsible for the commissioning, design and
installation of the network.

Negroponte has a home on Patmos and visits often. In the 1990s his
inability to get Internet access prompted him to set up a local dialup
Internet service provider - ISP 12Net. In 2001, Bletsas, then research
scientist and director of computing at the Media Lab, researched the
possibility of providing broadband Internet connectivity to Patmos.
Bletsas' paper "Wirefree in Patmos" was published in the BT Technology
Journal in October 2004.

"With the support of Uni Nortel and 12Net, the Wirefree Patmos we
envisioned is coming to fruition and the fact that we've used a Nortel
Wireless Mesh Network solution to do this is exciting because we
contributed to its development," says Bletsas.

The network will deliver the benefits of broadband Internet access across
the island and offer access for visitors. This will boost the island's
tourist trade by providing new communications options such as the ability
for visitors to keep up with news from home by watching streaming
videocasts online. In the Patmos school year starting September 2008,
high school teachers and students on Patmos and its surrounding islands
will be able to use the new network to access on-line educational
resources.

"The Patmos network provides affordable wireless access achieved
cost-effectively," adds Kostis Stavropoulos, managing director Uni Nortel.

Initially the Patmos network will use eight core nodes wirelessly
connected with a Nortel Wireless Bridge 7230 and 50 Nortel WP7220 and
WP7215 Access nodes, covering the major area of the island. Nortel was
ranked second in wireless mesh market share by Infonetics (Q4'07).
