COFDM mobile wireless video transmission equipment adopts advanced COFDM modulation technology and MPEG-2 or H.264 image compression technology, which can quickly and stably transmit high-definition audio and video signals in blocking mobile environment. COFDM mobile wireless video transmission equipment has the advantages of high sensitivity, wide coverage, good mobile performance, strong anti-interference ability and diffraction ability, which is widely used in modern wireless transmission field.
Although COFDM wireless image transmission mobile wireless video transmission equipment has advanced performance and powerful functions, in practical application, there are still some factors affecting its transmission distance.
1. Equipment power size
Generally speaking, under certain transmission environment and conditions, the greater the power of the equipment, the farther the transmission distance.
2. Same frequency electromagnetic signal interference
Although COFDM mobile wireless video transmission equipment has a very strong anti-interference ability, but for the same frequency signal interference, its transmission distance will also be affected.
Due to the earth radian, with the increase of distance, there will be a certain gap between the transmitter and receiver. Therefore, in the process of long-distance transmission, the corresponding position should be adjusted according to the altitude.
4. Antenna gain
Theoretically, the higher the gain of the antenna at the transmitting end of the equipment, the longer the transmission distance. When the transmitter adopts the high gain directional antenna, the power density (field strength) in the communication direction can be significantly improved, while the receiver using the high gain directional antenna can significantly improve the signal / noise ratio and the received field strength, thus greatly increasing the communication distance. Pengxinwei technicians will configure appropriate gain antenna for users according to the equipment and application needs of users. Maximize the power of the device.
COFDM mobile wireless video transmission equipment has the ability of diffraction, but diffraction will weaken the transmission signal. Therefore, the more dense the obstacles are, the closer the transmission distance is.
