Wirless accessing device

Abstract

The invention discloses a kind of wireless switch-in device which includes central control indoor model and remote switch-in outdoor model, which two are connected by wires. The former model accomplishes the normal function such as base band and middle frequency process, includes signal processing unit, MODEM unit, control unit, input and output unit, power unit and data correspondence interface and net management system interface; the post model includes several radio frequency unit and correspondent receiving and transmitting antenna. The invention has a lot of advantages.

Description

technical field [0001] The invention relates to a wireless access device of a communication system, in particular to a wireless access device for connecting a wireless node or a wireless network to a wired network. Background technique [0002] LAN (Local Area Network) is usually a network composed of different nodes (Node) connected by various physical media (such as twisted pair, coaxial cable, optical fiber). In the present invention, we call this kind of local area network a wired LAN. [0003] WLAN (Wireless Local Area Network) refers to a network formed by connecting nodes through a wireless transmission medium (such as infrared, radio frequency, etc. signals). In this way, the shackles of the wired physical medium of the traditional wired LAN are removed, which is very convenient for MNs (Mobile Nodes) that are often in a mobile state. As a fast and flexible local wireless access network, WLAN can provide high-speed data access services for MNs in hot spots. A typi...

Problems solved by technology

These APs generally have the following disadvantages: the power supply is inconvenient, and the nearby power supply needs to be provided when setting up the AP, but in many wireless applications (such as roofs and walls) there is no corresponding power supply; Once an AP fails, it is troublesome to detect the failure and replace the corresponding AP.
