Sometimes a power splitter is used when a wireless bridge is to have more than two antennas in a wireless surveillance project. So, what is a power splitter? What role does it play and under what circumstances can the power divider be used in wireless monitoring projects?
The power splitter full power splitter can divide one input signal into two or multiple outputs, and in turn can synthesize multiple signals into one output. In a wireless monitoring system, a wireless bridge uses a power splitter to distribute one signal of a bridge output to multiple antennas.
In the wireless monitoring system, when many customers use multiple transmissions to receive video signals, the receiving end can only use omnidirectional antennas to receive signals if the angle is not enough. The gain of the omnidirectional antenna is small, and the transmission distance is also small. Very close. At this time, the power splitter is used to increase the receiving antenna to increase the receiving angle. In this way, the receiving device can save engineering equipment costs, and the transmission distance is much farther than the omnidirectional antenna. In this case, using the power splitter can save investment and save costs.
The power splitter has these advantages. Is it necessary to add a power amplifier to the antenna in the wireless monitoring project? Of course not. The power splitter can be used within a distance of three kilometers. If the power splitter is used in the case of long-distance wireless video transmission, if an output port is not connected to the base station output signal, it must be connected. Matching load (ie load resistance) should not be idling; use the power splitter to increase the antenna gain if the distance transmitted is much lower. However, the use of the power splitter still affects the transmission distance. Since the power splitter is used to divide the power, it will definitely affect the transmission distance. Forming a blind spot: After using the power splitter, the network performance will be reduced, and some blind spots will be formed. Increase the amount of maintenance: Using the power splitter for the operation and maintenance work, a fault node is added invisibly, and the quality of the power splitter directly affects the quality of the network.
In summary, the power splitter should be used under proper environmental conditions, and blind use may cause the entire wireless monitoring system to malfunction. If you are not sure under what conditions, it is advisable to consult a Lean professional.
