Centennial Communications Selects Nortel 3G Solution
for Puerto Rico, Virgin Islands

SAN JUAN, Puerto Rico--(CCNMatthews - Jan 11, 2005) -

New Infrastructure to Improve Performance, Expand Capabilities for
Wireless Voice, Data Services

Centennial Communications Corp. (Nasdaq:CYCL), a leading wireless and
broadband telecom service provider in the Caribbean, has chosen Nortel
(NYSE:NT)(TSX:NT) to replace and upgrade its existing wireless network
in Puerto Rico and the Virgin Islands with advanced third generation
(3G) wireless technology.

This new 3G network -- based on CDMA2000 1X technology -- is expected to
increase subscriber capacity and expand service coverage to help address
growing subscriber demand for such wireless data services as mobile Web
browsing, e-mail and high-speed download of videos and graphics.

"Centennial is committed to offering its wireless customers the best
quality and most advanced service options," said Michael J. Small, chief
executive officer, Centennial. "We are strengthening our network
leadership by improving the reach, reliability, performance and
capabilities of our wireless infrastructure, a key differentiator for
our heavy usage wireless customers in this region."

"We are relying on Nortel's superior technology and extensive expertise
in deploying CDMA networks to ensure we have an infrastructure that can
meet the vast demand for wireless voice and data services in Puerto Rico
and the Virgin Islands today, while also giving us the capacity to
continue to grow and expand our service offerings in the future," said
Tom Cogar, chief technology officer, Centennial.

Nortel will deploy both core (switching) and access (radio base
stations, base station controllers) network equipment for Centennial.
The initial phase of the project is expected to be complete by July

"We're excited about working with Centennial to help them enhance the
communications experience of their subscribers with new, sophisticated
wireless services," said Kevin Taylor, vice president, Wireless
Networks, Caribbean and Latin America, Nortel. "Centennial can count on
our world-class technology and our 30-plus years of experience in
deploying advanced, reliable networks in the Caribbean region to help
them successfully complete this and future projects."

Centennial also selected Nortel in 2003 to deploy a CDMA 1X network in
the Dominican Republic.

"Centennial is a valued customer and we look forward to expanding this
relationship, and to continuing to work with them to evolve their
networks cost-effectively so they can provide advanced data services to
their customers," said Richard Lowe, president, CDMA Wireless Networks,
Nortel. "This contract also further enhances Nortel's leadership
position in providing mobile solutions for emerging markets like the
Caribbean and Latin America."

The new network being deployed by Centennial will be fully 1xEV-DO
ready. 1xEV-DO is a broadband radio technology that can support
transmission speeds higher than those currently available using ADSL and
cable modems. EV-DO provides speeds bursting in excess of 2 megabits per
second (Mbps). EV-DO users can expect more than 600 kilobits per second
(Kbps) average throughput -- equivalent to and in some cases better than
fixed broadband -- for high-speed broadband Internet, virtual office,
real-time video, and other data and multimedia services.

Nortel is deploying 1xEV-DO with leading customers around the world,
including Smartcom, Verizon Wireless, Telstra, Pelephone and Eurotel.
Nortel CDMA equipment is designed to support 1xEV-DO through modular
upgrades to existing hardware. This approach provides a cost-effective
and rapid method for bringing to market advanced wireless services and
associated revenues.

Nortel CDMA technology is designed to maximize existing customer
investments and help service providers drive down capital and operating
costs. It supports multiple frequencies, including 450, 800, 1900 and
2100 MHz. Nortel has designed, deployed and launched more than 300
wireless networks in more than 50 countries around the world. Nortel was
the first industry supplier to have wireless networks operating in all
advanced radio technologies (GSM/GPRS/EDGE, CDMA2000 1X and EV-DO, UMTS
and WLAN), and is the only end-to-end supplier of all new-generation
wireless solutions.
