African Mobile Operators Spacefon and Spacetel-Benin Choose NMS Communications' AccessGate to Optimize GSM Networks, Enable New Revenue-Generating Services.

FRAMINGHAM, Mass. -- Largest Mobile Operators in Fast-Growing African Markets to Realize ROI in Days, Not Months

Spacefon, the leading GSM operator in Ghana, and Spacetel-Benin, one of Africa's largest mobile operators, will use NMS Communications' (NASDAQ: NMSS) AccessGate(TM) wireless backhaul optimizer to reduce backhaul expense and bandwidth requirements. Not only will AccessGate (www.nmscommunications.com/solutions/WirelessAccess.html) help Spacefon and Spacetel-Benin significantly reduce backhaul operating expenses, but, equally important, the product will enable them to cost effectively increase capacity in Ghana and Benin, two of Africa's fastest-growing nations.

Network optimization in fast-growing markets such as Africa is critical, as African GSM networks are growing at an annual rate of 50 percent according to Mobile International Magazine, straining existing satellite and microwave links and causing delays for new service rollouts throughout the continent. With AccessGate, operators such as Spacetel-Benin and Spacefon are able to increase radio coverage and the revenue generated on these links without increasing the operational expense of the link.

"With more than 40 million wireless subscribers in Africa and an annual growth rate of 50%, we have no choice but to increase capacity of our GSM networks as quickly and economically as possible," said Joseph Helayel, Technical Manager, Spacetel-Benin. "Our goal is to provide the African continent with modern, efficient and cost effective GSM telecommunications services, and NMS' AccessGate network optimizer helps us do just that."

"NMS has been a terrific partner, working with us quickly to implement a solution to help us meet growth requirements and challenges we faced," said Rajesh Chengta, VSAT Link Director, Spacefon. "As we bring telecommunications service to many who've never had it, we expect it to serve as a catalyst to improve the living conditions of the people in the area."
