Mobile Internet settings
A low-latency 4G or 5G connection is recommended when using a mobile Internet connection with Web Radio Control server hardware. 3G connections can be used too, but 3G latency is significantly larger, which may interfere with audio streaming.
When choosing a suitable mobile Internet plan, make sure that the plan allows use of a public IP address, as it is required for accessing the Web Radio Control server software over the Internet. A dynamic IP address works well with a Dynamic DNS service — having a static IP address is not necessary.
