First, cable data transmission is independent of interference and distance from the device, a problem that laptop owners regularly face when using a Wi-Fi hotspot, USB-connect 20-30% less battery charge of the smartphone compared to wireless distribution, which is critical for long-term operation without an outlet.

Another key advantage is speed and latency, even under ideal Wi-Fi conditions. 5 (802.11ac) lose USB 2.0 In connection stability: the cable provides constant bandwidth without ping jumps, which is important for online games, video conferencing or downloading large files. USB 3.0 (For example, the Redmi Note model 11 Pro+ or POCO F4), speed 400-500 Mbit/s – comparable to wired Ethernet.

Finally, USB-The modem does not require password settings or create vulnerabilities for connecting third-party devices, as is the case with open Wi-Fi networks, which is especially true for corporate laptops or working with sensitive data. The only downside is the need for a physical cable connection, but for stationary PCs or hybrid jobs, this is rarely a problem.
