Singtel to launch Voice-over-Wi-Fi in August

This is in line with the positive result of its Heterogeneous Network (HetNet) trial.

Singtel will launch a Voice-over-Wi-Fi service in August, following the positive results of its Heterogeneous Network (HetNet) trial. 

The HetNet trial was conducted in collaboration with the Infocomm Development Authority (IDA) Singapore at crowded places in  the Jurong Lake District (JDL) such as malls, MRT stations, HDB neighbourhoods, and onboard a bus earlier this year. HetNet was also deployed at Marina Bay Sands, foodcourts, Nex, VivoCity, and Changi Exhibition Centre. 

The trial found that Singtel's mobile users could make "uninterrupted" voice calls and text over Wi-Fi in areas that are technically challenging for mobile signals, as their devices transitioned between mobile and Wi-Fi networks, without the need of an installed app.

In a press statement, Singtel said this will allow mobile users to call or text over Wi-Fi in locations such as basements and buildings above 20-storey high. The HetNet can also support the Internet of Things (IoT) to provide 24 by 7 connection to a real-time air quality sensing device tracking PSI and carbon dioxide levels. 

"We are encouraged by the positive results from the HetNet technology trials. Ninety percent 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. We will use the lessons from the trial to work with our industry partners to further enhance the experience of Singapore mobile users," said Gabriel Lim, co-Managing Director of IDA.

"In the near future, with millions of connected devices fueling data demand, ensuring a consistent experience for multiple mobile customers across different locations is paramount. With pervasive connectivity and higher data capacity set to become the norm, it was important for us to conduct a HetNet trial to gain further insights. Given our positive trial results, we are ready to support IoT with our networks and provide Singtel mobile users with high-quality voice calls and SMS island-wide," said Yuen Kuan Moon, Chief Executive Officer, Consumer Singapore at Singtel.

The VoWiFi service will be available at any accessible Wi-Fi hotspot, Singtel Premium Wi-Fi, and Wireless@SG locations.
