1. Introduction

On 21 March 2017, the CA promulgated its work plan for making available

additional radio spectrum for public mobile services to meet the increasing

aspirations of service users towards 2020 and beyond. The work plan has identified

a number of frequency bands, including the 3.4 – 3.6 GHz band (“3.5 GHz band”),

the 24.25 – 27.5 GHz band and the 27.5 – 28.35 GHz band (“26/28 GHz bands”),

that can be made available for reallocation to mobile services to prepare for the

launch of fifth generation mobile (“5G”) services.

China Mobile Hong Kong (“CMHK”) opened the 5G Open Lab of CMCC 5G

Innovation Center in Hong Kong on 16 March 2018, and was firstly granted the

trial permits from OFCA to conduct 5G network trials with commercial ready

products at 3.5GHz and 28GHz bands inside the 5G Open Lab.

During the lab trial arranged between 21 May 2018 and 10 August 2018, 5G

outdoor AAUs and 5G NFV core network equipment is set up inside 5G Open Lab

to demonstrate the peak throughput capacity of 5G network by Test User

Equipment (TUE), and end-to-end 5G network connectivity via 5G Customer

Premise Equipment (CPE) for internet browsing.

4.4 Speed test with handset through Wi-Fi connection with CPE

4.5 Basic tests with 5G Core

5 Conclusion

The trial verified the good coverage capability and high data throughput of 5G NR.

Even though the testbed environment contains many metal cabinets which may

result in interference, the RSRP was still able to reach up to -66 to -70 dBm. The

downlink throughput has achieved satisfactory results in the lab environment: 5G

NR with 100MHz of bandwidth at 3.5GHz reached up to 703Mbps and 5G NR

with 800MHz of bandwidth at 28 GHz reached up to 14.3Gbps. Moreover, an end-

to-end 5G network connectivity for internet browsing was demonstrated with good

user experience via a 3.5GHz 5G CPE. Speed test with an existing 4G handset

via the 5G CPE shows a download speed of 326Mbps.

Overall, the trial results served the purpose of showing good data performance of

5G network technology at 3.5 GHz and 28 GHz under indoor lab environment.
