Singtel and Ericsson have demonstrated 1Gbps on the mobile network of the Singapore operator, which plans to offer the service later this year.
Singtel will focus the investment on key high-traffic
locations, but the speed will be available only on certain
Mark Chong, the group’s CTO, said: "As the world
prepares for the 5G era, Singtel is leveraging its spectrum
assets and the latest advancements in mobile technology to
optimise our network usage."
The companies are using Singtel’s newly acquired
spectrum in the 2,500MHz band with quad-band carrier
aggregation (CA) – which means each link uses four
frequency channels at once to increase bandwidth. They are also
using both frequency-division duplex (FDD), which is common to
most mobile networks, and time-division duplex (TDD), a way of
making better use of spectrum resources.
Martin Wiktorin, Ericsson’s country manager for
Singapore, Brunei and the Philippines, said: "Singtel and
Ericsson have a common goal of delivering the best mobile
network in Singapore by seamlessly combining both FDD and TDD
technologies in one 4G LTE network."
Singtel is adding a system called bandwidth-aware CA, that
allows it to manage spectrum more efficiently and enables
smartphones to automatically select the best spectrum band
combination available, enabling optimum speeds. Ericsson and
Singtel estimated that this will give existing subscribers a
20% increase in speed.
Wiktorin said: "Singtel subscribers will be able to enjoy
higher speeds with bandwidth-aware CA, which also allows
network providers to manage spectrum utilisation more
Singtel said that following the successful trial, it will
progressively roll out the new technology at key high traffic
locations such as Orchard Road, Raffles Place, Tanjong Pagar
and Clarke Quay. Handsets supporting the 1Gbps speeds offered
by quad-band FDD/TDD CA are expected to be available from the
second half of 2018, it added.
