M1 trials HD VoWiFi over HetNet technology

03 May 2016

Singapore's M1 has launched the nation's first public native HD voice over Wi-Fi (VoWiFi) trial using HetNet technology.

The trial service supports calls to and from fixed numbers without having to use a separate calling app, and allows for two-way mobility between Wi-Fi and mobile networks for seamless handover.

M1 is using smart network prioritization technology to ensure quality voice calls over Wi-Fi even during periods of heavy network usage.

The operator is working with the Infocomm Development Authority (IDA) of Singapore on the deployment as part of the authority's HetNet Trials initiative.

The service is currently available to HetNet Trials users at M1's Wi-Fi deployment sites in the Jurong Lake District. The company has deployed six HetNet hotspots throughout the district, at locations including train stations and bus interchanges.

In addition to VoWiFi, M1 is working with IDA on the trial of Wi-Fi services on public buses.

Last month mobile operator 3 Hong Kong launched a premium voice over Wi-Fi service that supports the use of up to five devices, including smartwatches tablets and PCs, along with a smartphone connected to the same account.
