Taiwan's **National Communications Commission (NCC)** announced that mobile data services will be significantly throttled across 14 cities and counties in northern and central Taiwan for half an hour. This exercise is part of the annual **Urban Resilience Exercises**, which run concurrently with the **Han Kuang** military drills in mid-August. During the simulation, **4G** and **5G** mobile data speeds will be reduced to approximately 1% of their normal capacity. This drastic reduction is expected to render services like video streaming, video calls, social media, and large file transfers largely unusable. However, essential services such as voice calls, text messages, emergency alerts, and calls to emergency services will remain functional. Authorities have clarified that this is not a complete internet shutdown. Fixed broadband, **WiFi**, landline telephone services, military communications, and other dedicated networks will continue to operate without interruption. The primary objective of the drill is to prepare residents to seek alternative communication channels should mobile data networks become unreliable during an actual crisis. Officials are urging citizens to take proactive measures, including downloading offline maps, utilizing **WiFi** for scheduled online meetings, and establishing backup communication plans with family members. Beyond the communications test, the **Urban Resilience Exercises** encompass a broader range of preparedness activities. These include rehearsing civilian evacuations, expanding emergency medical capacity, and evaluating the use of drones for delivering essential supplies and medical equipment. Taiwan's Ministry of Defense indicated that the outcome of this drill will help determine whether similar exercises should be expanded to other parts of the island. The increased emphasis on resilience reflects Taiwan's growing concerns over potential military conflict, particularly with **China**, and the persistent threat of natural disasters like typhoons and earthquakes, which have previously caused disruptions to undersea communication cables.
