Transmission distance: Point-to-multipoint is usually in the form of multiple transmitters and one receiver, and the transmitter is mostly connected to the camera. When using this form, pay attention to the transmission distance, and the transmission distance within 10 kilometers can use point-to-multipoint. The transmission method. More than 10 kilometers, can only adopt the point-to-point transmission mode, so as to ensure the stability of wireless monitoring transmission.
The problem of angle: Wireless bridges have an angle. Point-to-multipoint transmission is also considered in terms of angles, depending on how large the angle of the receiver is to receive the signal in front of it completely. The general angle is 30 degrees, 60 degrees, 90 degrees, 180 degrees, and 360 degrees. Ryan can achieve different requirements through external antennas. If omnidirectional reception is required, the transmission distance should preferably not exceed 1 km.
Broadband problem: To comprehensively consider the pixels of the front-end camera, the required bandwidth, if the pixels are too high, or if the transmitted data is too large, high bandwidth will be required. When designing point-to-multipoint transmission, it is necessary to comprehensively consider the bandwidth. Increase the amount of receiving equipment.
Lian Technology currently has 300M, 800M equipment, how to design a specific program, you can call Leian staff.
Wireless monitoring equipment can be transmitted point-to-point, point-to-multipoint transmission, relay mode transmission. The peer-to-peer approach refers to one transmission, one reception, one-to-one transmission. The front end can be a camera, or multiple ones can be transmitted in one-to-one fashion after the signals are collected through the switch. The point-to-multipoint approach is multiple front-end transmissions and one reception. The relay transmission mode refers to transmission through the establishment of a relay station in the case of blockage. Which point-to-multipoint transmission methods need attention?
