Abstract

The invention relates to a WiFi wireless accessing panel, by the deployment of which the interference of the environment to the WiFi can be reduced and the signal coverage scope of the WiFi can be improved. The panel is transmitted to the WiFi wireless point by the Ethernet cable and then is switched to the WiFi wireless signal which reduces the loss of the signal. The invention supports the power over Ethernet for the convenient deployment. The invention also supports the wireless mesh network which optimizes the coverage of the WiFi signal and the choice of the WiFi circuit. The invention supports the extended service set by which the WiFi wireless client can realize the roam by the same SSID.

Description

technical field [0001] The present invention relates to WiFi (Wireless Fidelity) wireless network technology and Ethernet power supply (PoE: Power over Ethernet) technology, in particular to a panel for providing WiFi wireless access. Background technique [0002] WiFi wireless network technology, including IEEE802.11b and IEEE802.11g, provides a technical standard for terminal equipment to access a local area network wirelessly. WiFi works in the 2.4GHz frequency band, and the highest transmission rate can reach 11Mbps (IEEE802.11b) and 54Mbps (IEEE802.11g) respectively. It has the characteristics of convenient deployment, reliable communication, low cost, good flexibility, strong mobility, and high throughput. WiFi enables wireless users to obtain Ethernet-level network performance, speed and availability, and can seamlessly integrate multiple LAN technologies to form a network that can meet user needs to the greatest extent. [0003] However, WiFi technology has the foll...
