Radcom won’t name the customer, but the network testing and monitoring vendor said today it has landed its first deal with a U.S. carrier for 3G monitoring solution. A company spokeswoman said the deal is with a Tier I nationwide carrier for its CDMA 1x EV-DO network, meaning the two likely candidates are Sprint and Verizon Wireless.

Radcom will deploy its Cellular Performer monitoring and troubleshooting system initially in five of the unnamed carrier’s markets with plans to bring the solution nationwide by the end of the two-year contract. While no price tag was assigned to the contract, the Radcom spokeswoman said it is a potential multimillion-dollar deal for the vendor.

Radcom’s solution continuously monitors and analyzes signaling, voice and data traffic over the network, setting off multi-tiered alarms when performance quality dips or power levels drop in order to immediately isolate and troubleshoot problem areas. Radcom is also supplying its Performance Analyzer software, which tracks the historical behavior of the network to help with later network overhauls, the revamping of the network footprint and development of new infrastructure.

The deal is Radcom’s first for an EV-DO network and is its second monitoring contract publicly announced with a U.S. carrier--it announced a deal with Dobson Communications for monitoring of its GPRS network last year.
