Vodafone Ziggo completes voice call over open RAN

By Wireless Watch Staff

Vodafone Ziggo of The Netherlands is working with Altiostar and NEC on open RAN tests. The companies have announced the first successful voice call made on an open RAN. The two vendors, which are also part of Rakuten Mobile’s network and are reported to be working with Bharti Airtel (see separate item), integrated their respective products with general purpose hardware.

“We are delighted to work together with NEC towards the first live Open RAN site,” said Ruud Koeyvoets, a Vodafone Ziggo director.  “The introduction of the technology enables us to introduce new suppliers, such as Altiostar, giving us greater flexibility when rolling out our mobile network. We’re proud to be pioneering the development of Open RAN and will be monitoring the performance of this pilot.”

NEC also announced that it is working with Analog Devices (ADI) to design a 5G Massive MIMO radio/antenna unit for Rakuten, using ADI’s fourth generation wideband RF transceiver solution, which integrates quad-channel transmitters, receivers and digital pre-distortion (DPD) in a single chip. The radio is software reconfigurable and covers all sub-6 GHz 5G bands.
