Licensed long-range fixed wireless communications are generally utilized when it's important to secure specific frequencies for exclusive use, usually to prevent interference and guarantee reliability across distances for critical operations. Such frequencies are typically purchased or leased by companies which require consistent communication channels that remain unclogged by public traffic, like television broadcasters or cellular service providers. Unlicensed bands are often subject to interference from other devices and are used for short-range communication modes like Wi-Fi and Bluetooth, which is why they are not suitable for establishment of critical communication infrastructures that need exclusivity and guaranteed quality of service over long distances.
