Problems solved by technology
[0003] During the research and practice of the existing technology, the inventors of the embodiments of the present invention found that the CPE has two sets of internal and external antenna systems to meet the needs of different scenarios of users at the same time. Generally, the interfaces of the antenna system are standard configurations , such as 50Ω SMA interface, etc. The external antennas on the market are uneven, and the actual user experience brought by external antennas with different performances will be quite different. When the user end uses an unmatched external antenna, It will lead to poor performance of CPE and unstable signal during signal transmission, affecting CPE performance and thus affecting user experience

The invention discloses an antenna selection circuit structure, an antenna selection method and client front-end equipment, and the antenna selection circuit structure comprises an antenna voltage detection circuit, an antenna selection circuit, a built-in antenna circuit and a radio frequency module, wherein the radio frequency module is electrically connected with the antenna selection circuit,the antenna selection circuit is electrically connected with the built-in antenna circuit, and the antenna voltage detection circuit is electrically connected with the antenna selection circuit. According to the embodiment of the invention, whether an currently accessed external antenna is an antenna matched with the CPE or not can be determined through a specific v voltage ratio; when the CPE detects a preset voltage, the antenna switch is switched from the built-in antenna circuit to the external antenna, and when the CPE does not detect the preset voltage, the antenna switch can always keepconnection with the built-in antenna and prompt that the external antenna is not matched in a user interaction interface; by comparing voltage signals, an antenna line is selected by selecting a switch control pin according to a voltage signal, so that the client can only configure a specified external antenna to the CPE.
Description
technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to an antenna selection circuit structure, an antenna selection method, and customer front-end equipment. Background technique [0002] With the continuous development of communication technology, a large number of terminals such as smartphones, tablet computers, and notebook computers are widely used, and terminals are developing in a diversified and personalized direction, and have increasingly become indispensable terminals in people's life and work. Today, Terminals such as mobile phones and tablet computers have become electronic devices that people carry with them every day. Therefore, in order to provide users with more stable and reliable high-speed broadband services comparable to optical fiber, more and more operators have begun to explore large-scale use of customer front-end equipment ( Customer Premise Equipment, CPE). CPE is actu...
