SINGAPORE: Singtel will roll out Singapore's first commercial Voice-over-WiFi service in August, the telco announced on Tuesday (Jun 21).
The service will allow users to make voice calls and text messages over WiFi in areas that are challenging for mobile signals, such as basements and buildings over 20 storeys high. On the service, smartphones will transit seamlessly between mobile and WiFi networks, as long as the user is at any accessible WiFi hotspot, such as homes, Singtel Premium WiFi and Wireless@SG locations.
Singtel said this rollout comes after positive results from its Heterogenous Network (HetNet) trial conducted at the Jurong Lake District, which was a collaboration with the Infocomm Development Authority of Singapore (IDA).
The trial also "demonstrated the readiness of Singtel’s HetNet to support IoT (Internet of Things) in providing, for example, reliable, 24/7 connection to a real-time air quality sensing device tracking PSI and CO2 levels – only one of its kind in Southeast Asia," Singtel said.
“We are encouraged by the positive results from the HetNet technology trials," said Mr Gabriel Lim, co-Managing Director of IDA, adding that "90 per cent of the trial users enjoyed a better mobile experience, with faster download and upload speeds."
"They also enjoyed better connectivity, smooth transitions between wireless and cellular networks, and more enjoyable mobile surfing experiences at crowded areas such as train stations," he added. "We will use the lessons from the trial to work with our industry partners to further enhance the experience of Singapore mobile users."
Users may take part in the trial and provide their feedback until the end of June.
