WiMAX Forum® Announces First Commercial Global Roaming Trials at WiMAX Forum Global Congress 2009

Aicent aims to play key role in evolution of next generation wireless roaming

AMSTERDAM - June 2, 2009 -- The WiMAX Forum today announced at its second annual Global Congress 2009 in Amsterdam that 14 ecosystem leaders are participating in the first ever commercial WiMAX interoperability and roaming trials. These operators, device manufacturers, equipment vendors, and clearing houses include Aicent, Alvarion, Bridgewater Systems, Cisco, Clearwire, Comfone, DigitalBridge Communications, Intel, iPass, Juniper Networks, MACH, Motorola, Syniverse and Transaction Network Services.

"This trial represents an end-to-end test of roaming over live WiMAX networks and will provide a baseline for establishing roaming services and agreements for WiMAX worldwide." said Ron Resnick, president and chairman of the WiMAX Forum. "Roaming with interoperability is important in order to expand the availability of WiMAX services by enabling users to automatically access networks when traveling outside the geographical coverage area of their home network."

The commercial trial provides another platform for the WiMAX Forum to aggressively position operators and clearinghouses to initiate commercial roaming services which will lead to roaming worldwide. Additionally, the WiMAX Forum provides operators and vendors with all the information needed to understand WiMAX roaming and to launch roaming services at www.wimaxroaming.org, including technical specifications to follow when implementing roaming and a business agreement template to use with other operators.

"The testing of networks and equipment on leading operator networks will demonstrate to all WiMAX operators that they can easily provide roaming services to their customers," said Resnick. "The goal is to demonstrate the WiMAX standard end-to-end roaming implementation that will be replicated by WiMAX operators and clearinghouses worldwide.

This includes WiMAX networks which support roaming services and the roaming back office platforms which track and measure usage for operators to correctly settle accounts with each other." Currently, WiMAX Forum tracks more than 475 WiMAX network deployments in 140 countries. A complete detail of WiMAX networks is available at http://www.wimaxmaps.com
