3 Hong Kong has announced the successful completion of 5G outdoor network trials in the 3.5-GHz and 28-GHz spectrum bands ahead of the commercial availability of the technology.
The company said it believes it was the first mobile operator in Hong Kong to complete a live outdoor 5G trial broadcast. The test was conducted at a trial cell site in Causeway Bay.
3 Hong Kong received an indoor 5G test permit for the 3.5-GHz band in August 2017, and completed a number of initial trials by the end of that year. In May, the company secured a temporary permit to conduct 5G trials in the 26-GHz and 28-GHz millimeter wave bands.
Another temporary permit for outdoor and indoor trials in the 3.5-GHz band was granted in June, and the company achieved 2Gbps network speeds during an earlier trial using 100MHz of spectrum in this band.
3 Hong Kong said the test results indicate that 3.5-GHz band coverage – when used in conjunction with the new 5G technology named Massive MIMO, can be comparable to the coverage afforded over LTE using the 1800-MHz band.
The design of 5G networks will use a combination of mid-band spectrum such as 3.5-GHz for a wider coverage area, and millimeter wave spectrum for high speeds
"3 Hong Kong took the initiative to carry out end-to-end trials in various 5G bands in preparation for a new era of mobile communications,” commented Kenny Koo, CEO of 3 Hong Kong's parent company Hutchison Telecommunications Hong Kong Holdings (HKHTH).
“We welcome the government’s decision to allow various of its premises to accommodate 5G base stations, and we hope the application and approval processes can be simplified and accelerated to help Hong Kong’s 5G development.”
