Carrier Access Announces Unique Optimization Solution for Wireless Providers

Carrier Access® Corporation (NASDAQ: CACS), a leading provider of wireless and voice integration solutions, today announced its leading-edge, total and complete optimization solution for wireless backhaul. With its FLEXengine(TM) technology and the release of its FLEXengine 2.0 software embedded in its solutions, Carrier Access helps wireless providers not only optimize their networks, but perform optimization across TDMA (time division multiple access), GSM (global system for mobile communication), and UMTS (universal mobile telecom system) simultaneously, delivering a complete solution for all wireless technologies at a cell site.

"There's a lot of interest among GSM and W-CDMA operators in moving from TDM to Ethernet-based backhaul," said Heavy Reading Senior Analyst, Patrick Donegan. "But that isn't a viable near term option for many operators in many parts of their network and for some operators it isn't viable anywhere at all. In these cases, the operators need to look at other ways of optimizing their existing backhaul network and Abis optimization is one of those options."

Carrier Access FLEXengine release 2.0 provides operators with software-defined solutions to save on backhaul costs today and expands IP network bandwidth for media services of the future. It is capable of optimizing wireless backhaul across the generations of wireless transmission technologies (TDMA, GSM and UMTS). FLEXengine circuit bonding techniques are designed to overcome line interference and corruption on microwave links or copper circuits voice quality and call integrity. Network operators are positioned to improve network quality and meet customer expectations of always-on wireless services.

"Network operators are increasingly strategizing about how to save money on their wireless backhaul costs," said David Ratner, senior vice president of wireless products and solutions, Carrier Access. Ratner continued, "Carrier Access delivers a single solution that can drive operational and capital expenditure savings across 2G, 2.5G, and 3G networks, in both vendor-agnostic and vendor-specific modes, making it the most complete solution on the market today."

Additionally, FLEXengine 2.0 is capable of being remotely upgraded to provide new capabilities without requiring hardware changes, such as pseudowire MPLS support to help operators transform their architectures in an evolutionary fashion to all IP networks. FLEXengine 2.0 is the software core of multiple Carrier Access solutions, including the MASTERseries(TM) and Axxius® products, and it is being integrated into the EdgeFLEX(TM) product.
