StarHub will offer Voice over Long Term Evolution(VoLTE) services
next year promising clearer calls for its 4G users.
VoLTE enables customers to make high-definition(HD) voice calls
over a 4G network by allowing more speech information sent at
broader frequency range and over twice the bandwidth as compared to
standard voice calls. This results in natural-sounding and
significantly clearer phone conversations with reduced background
noise, StarHub said.
The company currently provides HD voice calls over 3G. Each time a
StarHub 4G user answers the phone, he switches to a 3G network for
HD calls. But with the 4G VoLTE, he can answer a HD call and
simultaneously check the Internet at 4G speeds should he need
to.
Major mobile handset manufacturers will roll out more phones that
support 4G VoLTE next year, StarHub said, The telco is believed to
be the first in South-east Asia to make such a phone call. VoLTE
has already been used in South Korea and the United States. StarHub
currently has over 440,000 4G subscribers and islandwide coverage
for its 4G networks.
