[0002] Cable TV network coverage mainly transmits TV signals through wired means, but in certain specific scenarios, such as remote areas or temporary facilities, wireless transmission technology may be considered to expand or supplement cable TV network coverage due to the high cost or impracticality of laying wired networks. In this case, the signal tower can act as a relay station to assist in wirelessly transmitting TV signals to these areas, and, as technology develops, some cable TV network operators are also exploring the integration of wireless technology into their networks to improve the flexibility and coverage of the network. For example, by using signal towers as wireless access points, wireless broadband access services can be provided to users, thus complementing cable TV network services.
