A long-range microwave interface is a type of wireless communication that uses high-frequency radio waves to transmit and receive data over long distances. A long-range microwave interface typically uses a parabolic antenna, also known as a dish antenna, to focus the radio waves into a narrow beam that can travel farther and with less interference than an omnidirectional antenna, which radiates the radio waves in all directions1.
One of the most common causes of input errors on a long-range microwave interface is the misalignment of the parabolic antenn a. Input errors are errors that occur when the receiver cannot properly decode or process the incoming signal. If the parabolic antenna is not aligned correctly with the transmitter, the receiver may not be able to capture the full strength of the signal, or it may pick up unwanted noise or interference from other sources. This can result in corrupted or lost data, which will increase the input error count23.
To troubleshoot this issue, the junior network administrator should check the alignment of the parabolic antenna and make sure it is pointing directly at the transmitter. The administrator can use tools such as a spectrum analyzer, a signal strength meter, or a path alignment tool to measure and adjust the signal quality and alignment of the antenna24.
The other options are not likely reasons for the input errors on a long-range microwave interface. A long-range microwave interface does not use an omnidirectional signal, so it cannot be jammed or weakened by other sources. The parabolic signal does not depend on the routing protocols used by the network, so it cannot be affected by improper routing protocols.
