Vodafone has touted the success of tests to trial to Voice over LTE (VoLTE) call services, allowing phone calls to be made over its 4G network.
The test, at its labs in Newbury, showed that it was possible to host calls over the spectrum it uses for its 4G network, offering far higher quality calls than over its exiting 2G and 3G spectrum holdings.
Fergal Kelly, CTO at Vodafone UK said the work underlined its commitment to boost that quality and capabilities of its network.
“Our trial of VoLTE, less than a year after the launch of our 4G network, is the next major innovation, and is hugely important as we continue our work to build the UK’s best network,” he said.
VoLTE calls have long been touted as the next evolution of phone calls but to date little progress has been made bringing this to market. Vodafone said it intends to continue its trials to develop services further, although it stopped short of saying if any live services would be offered.
Rival EE recently announced its intention to bring voice of WiFi calls to its customers, which will allow users to make calls using the native dialer within smartphones. Three and O2 over voice of WiFi calls already, but this is via dedicated apps.
The announcement of the tests comes three months after it revealed it has been working with Huawei on small cell technology developments, in an effort to boost mobile data services by offering high-speed upload and download speeds.
