5.8GHz remote station construction scheme
1. Description of Remote Station
The remote station (RU) communicates with the central base station (AP) wirelessly, and connects to the local LAN through the 100 / 10Base-T Ethernet interface. Each user can share bandwidth with other users via an Ethernet switch or router to improve the efficiency of the entire network. At the same time, it is easier to deploy in the network.
1. The remote site (CPE) equipment includes: outdoor RF units that provide RF functions and can send and receive wireless signals, indoor units that provide Ethernet power, routers and switches used to connect users of different networks, UPS power supply, parabolic directional antenna RF cable and SSTP twisted pair.
2. The outdoor unit (ODU) adopts waterproof design, which can adapt to the outdoor temperature change of -30 ℃ ~ 60 ℃.
3. The indoor unit (IDU) is an Ethernet power supply, including a data interface and a power module.
The structure of the remote station (CPE) is shown below

Second, the device configuration
The standard configuration of a remote station (CPE) includes: outdoor unit, indoor unit, Ethernet switch, UPS power supply, SSTP twisted pair and parabolic directional antenna.
The standard configuration products included in the cabinet of each remote station equipment are:
1. Outdoor radio frequency unit (ODU), 1 set;
2. Indoor power supply unit (IDU), 1 set;

4. Description
The number of remote station (CPE) equipment varies according to the number of users in each sector, and each remote station (CPE) corresponding to each sector of each central base station (HE) deploys at least one set of equipment.
Electric Fan referred to as fan, also known as fan, fan fan, is a motor-driven fan rotation, to achieve the air to speed up the flow of household appliances, mainly for cool Jieshu and circulation of air. Widely used in homes, classrooms, offices, shops, hospitals and hotels and other places.
The fan is mainly composed of fan head, fan blade, net cover and control device and other components. Fan includes motor, front and rear cover and shaking head blowing mechanism. The main components of the fan are: AC motor. Its working principle is: power coil in the magnetic field in the force and rotation. Electric energy into mechanical energy, and because of the coil resistance, so inevitably part of the energy to be converted into heat.
Common household fans are essentially axial fans, that is, the flow of wind parallel to the fan axis of rotation.
