Anritsu Co. introduces Voice over LTE (VoLTE) supplementary service test capability for its MD8475A Signaling Tester that includes the ability to confirm operation of services, such as call forwarding and call waiting, under a variety of network conditions. Introduction of these options extends the MD8475A’s VoLTE test capability and builds on the Signaling Tester’s integrated functionality to simulate LTE and IP Multimedia Subsystem (IMS) networks as well as an IMS client, providing a comprehensive test environment for UE manufacturers to verify device functionality.
In the recent IMS/VoLTE Competitive Assessment, ABI Research rates Ericsson as the overall leader with respect to innovation and implementation. Ericsson’s large cache of IMS and VoLTE patents, industry leadership in interoperability testing, and market share firmly places them in the top position. Closely at their heels are Alcatel-Lucent and Nokia Siemens Networks, both of whom have strong portfolios, and in some aspects are superior. Alcatel-Lucent and Nokia Siemens Networks hold dominant positions at the most demanding, leading wave LTE IMS deployments, and Nokia Siemens Networks is ahead with virtualization technology. Additionally, the Huawei and ZTE unique propositions are noteworthy.
Wireline operators have been the largest market for IMS services to date, but due to an increase in the number of mobile IMS deployments, ABI Research forecasts IMS revenues to reach $3.4 billion in the next five years.
Agilent Technologies Inc. announced that the Agilent PXT wireless communications test set is now available for testing voice quality on Voice-over-LTE (VoLTE) 4G phones with the Brüel & Kjær PULSE Audio Analyzer and Head and Torso Simulator (HATS).
