Spirent Spends $25M on Radvision VoLTE Unit

Test and measurement vendor Spirent has agreed to acquire the voice-over-LTE (VoLTE) and VoIP testing assets of fellow T&M vendor Radvision for $25 million, the pair announced on Wednesday.

Tel Aviv-based Radvision is a wholly owned subsidiary of Avaya Inc. , specializing in signaling, multimedia, and IMS for VoIP and VoLTE testing. The company works with chipmakers, mobile device manufacturers, and network operators, and claims to have helped enable the majority of today's voice- and video-over-IP deployments, including VoLTE launches.

Spirent Communications plc was a finalist for both "Best Deal Maker" and "Outstanding Test & Measurement Vendor" in Light Reading's 2014 Leading Lights, in large part for its big push into VoLTE testing. The company says it will use Radvision's toolkit to strengthen its own VoLTE testing, helping operators get off the ground with the 4G voice tech, lessen the impact on battery life and signaling, and add richer communications apps to it.

Avaya will continue to run Radvision's video business unit, but the company's Technology Business Unit (TBU) will join Spirent's Wireless and Service Experience division. (See Spirent Intros Nomad HD for VoLTE.)

Spirent's stock was down slightly, by 0.65%, to $97.30, in Wednesday morning trading. It expects the deal to close in 30 to 60 days and to enhance earnings and cash generation in the first full year.

VoLTE test time I'd like to hear more about what the T&M guys like Spirent have found out from VoLTE testing given all the delays. These first months of deployment in the US will be critical, and I have a feeling there will still be some kinks.
