Core Viewpoint - The article discusses how a metal box can enhance the speed of data migration between mobile phones by blocking external electromagnetic interference and optimizing internal electromagnetic coupling between the devices [1][3]. Group 1: Technical Explanation - The metal box can block external electromagnetic interference, allowing for tighter near-field electromagnetic coupling between the phone antennas, which increases the effective antenna area and reduces external interference signals [1]. - The OPPO ColorOS team mentions that dynamic optimization at the protocol layer can automatically adjust to higher frequency bandwidths under less interference, particularly with the latest WiFi 7 communication protocol [3]. Group 2: Methods to Improve Data Migration Speed - Using public Wi-Fi can lead to bandwidth congestion, which slows down the migration process. It is recommended to check the number of devices connected to the same network [5]. - Wi-Fi interference can be minimized by understanding the characteristics of different Wi-Fi frequencies. For instance, 2.4GHz Wi-Fi can be interfered with by devices like microwaves and Bluetooth, while 5GHz Wi-Fi has weaker wall penetration and requires proximity to the router for optimal speed [6][9]. - High CPU load during data migration can cause the phone to overheat and throttle performance, which can slow down the process. Additionally, low battery levels may lead to automatic performance restrictions [9].
