Abstract

The invention discloses a method, a device and a system for expanding a POE (Power Over Ethernet) service radius. The method mainly comprises the following steps: adjusting the strength value of a received first network signal sent by former power supply equipment to be the strength value of a second network signal needed by latter power receiving equipment, wherein the strength value of the second network signal is more than that of the first network signal, and according to the strength value of the adjusted second network signal, determining second power supply information required for transmitting the second network signal, adjusting the received first power supply information sent by the former power supply equipment to be the determined second power supply information, and transmitting the adjusted second network signal to the latter power receiving equipment by the second power supply information. With the adoption of the method, the problem that a transmission line is limited because the network signal and the power supply information are easily attenuated when transmitted by a system line is effectively solved, and the service radius of a POE switchboard is prolonged.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for extending PoE service radius. Background technique [0002] The full name of PoE is Power Over Ethernet, which refers to power supply through Ethernet cables, and its reliable power supply distance is up to 100 meters. [0003] PoE technology can be used to centralize power supply for terminals such as IP phones, wireless APs, portable device chargers, card readers, cameras, and data acquisition. For these terminals, it is no longer necessary to consider the indoor power supply wiring problem, and the power supply to the equipment can be realized while connecting to the network, which improves the ease of use and reliability. [0004] The current PoE power supply has a unified standard. As long as the published IEEE802.3af-2003 and IEEE 802.3at-2009 standards are followed, the problem of compatibility between devices from different ma...
