MetroPCS Selects TrueCall for LTE Network Visualization and Optimization

Understanding Subscriber Experience Critical For New Deployment

Berkeley, California – February 1, 2012 – Newfield Wireless® announced today that MetroPCS Communications, Inc. has acquired a nationwide license for the use of TrueCall® network visualization and optimization software for its LTE network. This announcement builds on a long relationship between the two companies related to TrueCall on the MetroPCS CDMA network as well as for model calibration services.

“MetroPCS understands the power of visualizing customer experience and optimizing our network in real time,” said Ed Chao, senior vice president corporate engineering and network operations for MetroPCS. “This becomes even more important when rolling out a new technology, new devices and as we evolve our network. We rely on the visibility TrueCall provides us – whether it’s a traffic snapshot of an entire market or the experience of a single LTE subscriber.”

TrueCall’s ability to deliver real-time status of LTE sessions provides operators with a window into their 4G network to measure network/device performance and overall subscriber experience. It delivers an end-to-end network view (RAN and core) in real-time based on individual sessions. With an intuitive user-friendly interface, TrueCall is capable of drilling down to each individual LTE session. The application is vendor agnostic and scalable to an operator’s network size and associated budget.

“We’re pleased to be supporting the MetroPCS network evolution to LTE,” said Marc Bensadoun, chief executive officer, Newfield Wireless. “The ability to visualize – and optimize – subscriber experience is a powerful advantage in the quest to retain existing customers and grow market share during the transition to LTE.”
