In response to the exponential demand for data services, the Company began to provide 5G network services on June 30, 2020, and continued to actively deploy 5G network. By the end of 2022, TWM was providing 4G/5G dual connectivity mobile broadband services in more than 96% of Taiwan’s administrative regions, with 5G covering over 81.7% of the population.
In addition to the continuous improvement of network coverage in metropolitan areas, TWM’s 5G networks has actively overcome the problems in remote areas and outlying islands. By the end of 2022, 83.9% of rural areas have been provided with 4G/5G Dual Connectivity mobile broadband services, so as to optimize the network quality of users in remote areas and outlying islands.
Three disconnection affected TWM services in 2022. Here is a description of the case and the measures taken to improve the situation:
|03/03||Taiwan Mobile's large-scale power blackout affected some areas where voice and data services could not be provided.||This incident is due to the lack of electricity in the whole area of Taiwan Power. The base station has backup power. Moreover, the base station reduces the load of some signals and reserves the main signal frequency band during an external power blackout. Thus, longer uninterrupted service is maintained.|
|05/14||The Chunghwa Telecom’s submarine cable to Matsu was broken, so Chunghwa Telecom activated microwave backup.||This incident was caused by an obstacle in the submarine cable between Taiwan and Matsu, which caused Chunghwa Telecom to provide microwave transmission backup immediately.|
|06/28||At 9:50 a.m. on that day, the traffic from HiNet was interrupted and it was found in the circuit between Taiwan Fixed Network and Chunghwa HiNet. After urgent repair by Chunghwa Telecom, it was restored at 10:35.||NCC investigated the cause of the incident and the attribution of responsibility, and ordered Chunghwa Telecom to reconfirm before taking action to disconnect the network. In the future, Taiwan Mobile will coordinate with Chunghwa Telecom on a reasonable network protection mechanism in accordance with the instructions of the NCC. In the future, the perfect horizontal connection and re-confirmation mechanism will be introduced on the basis of automatic judgment to take into account information security and user rights.|
