Huawei and ZTE provided vendor support for LTE-Advanced Pro trials
Sri Lankan mobile operators Dialog Axiata and Mobitel recently carried out trials of LTE-Advanced Pro technology. The test was carried out on its LTE network in partnership with Chinese vendor Huawei, Dialog Axiata said.
“The demonstration established the capability of the network to deliver throughputs in excess of 1 [gigabit per second] on the LTE Radio (Air) Interface, setting a solid foundation for the future evolution of the nation’s 4G services to a technology generation well ahead of neighboring markets,” Dialog Axiata said in a statement.
“Following the ‘4.5G’ technology capability test, Sri Lanka joins a select circle of 20 countries where 4.5G capabilities have been demonstrated,” the operator, which initially launched commercial 4G LTE services in 2014, said.
Mobitel also confirmed it has reached speeds exceeding 1 gigabit per second in its trials of LTE-Advanced Pro technology with partners Huawei and ZTE; tests were conducted in a Mobitel facility.
“Having successfully tested the 4.5G LTE-Advanced Pro technology, Sri Lanka telecom Mobitel is looking forward to commercially deploy the 4.5G services to the nation for further strengthening the evolving [information and communications technology] industry,” Mobitel said in a release. However, the telco did not provide further information on the future launch.

ZTE partners with China Mobile Research Institute to complete 5G high-frequency technology phase test
In other APAC news, Chinese ICT services provider ZTE has completed its prototype verification and performance testing of key “5G” high-frequency technology in partnership with the China Mobile Research Institute in Shanghai.
The joint test verified multiple technical performance indicators, including indoor transmission performance of the 5G high-frequency prototype in the 15 GHz band, single-user peak rate, transmission rate in line-of-sight/non line-of-sight scenarios and indoor penetration loss and coverage. The test achieved a single-user peak rate over 3.7 gigabits per second and service transmission performance for direct wave, reflection and transmission scenarios were deemed good.
“High-frequency communication is one of the key 5G technologies. It takes advantage of broadband transmission to multiply system capacity and can be applied in hot-spot large-capacity scenarios,” the vendor said.
