Microwave Communication: Using a Microwave Link

Microwave transmission involves the sending and receiving of microwave signals over a microwave link. This microwave link is made up of a string of microwave radio antennas. They're located at the top of towers at various microwave sites.

Microwave Transmission is Considered a 'Line of Sight' Technology.
Microwave transmission is considered a 'Line of Sight' technology. This is because the proper functioning of microwave transmission requires empty air. The airspace between two point-to-point microwave towers must be clear of mountains, buildings, and other objects. These things can block microwave signals.

Microwave transmission - although long distance - is limited by this need for a clear line of sight. It is also susceptible to attenuation by the atmosphere and rain fade. For these reasons, microwave transmission is only widely used in areas without LAN or other transport methods.

To make sure that any new microwave site will work properly, you need to prepare. Conduct a microwave line-of-site survey to verify whether open space is available between your two locations.

Analog or Digital Options with Microwave Transmission.
Microwave gear can be used to transmit both analog and digital microwave signals. Analog microwave transmission often saves money for microwave site staff. It doesn't require the purchase of any new equipment. You also don't have to train your staff on new transport systems. An extra benefit of familiar analog microwave transmission is that your operators know its exact transport capacity.

Users of digital microwave transmission find it easier to obtain support and gear for their systems. That's because digital transmission is the newer, more advanced form of microwave communication. Increased microwave transmission speed will also allow for more traffic - including remote monitoring data.

Monitoring Your Microwave Transmission Equipment Protects Your Reputation.
You need to monitor all of your mission-critical microwave gear. It doesn't matter what your microwave transmission method is. Monitoring enables you to quickly respond to microwave transmission errors. This quickly brings your network back online to protect your revenues. It also safeguards your reputation with your customers.

Troubleshoot Your Microwave Transmission Using Ring Polling
Microwave sites are most likely found in a ring formation. That's why you can use your network monitoring system to perform advanced monitoring applications. One such technique for determining the locations of problems is ring polling. This troubleshooting technique will also allow you to continue microwave transmission during a break between single sites.

Microwave data is sent from site to site sequentially, and can be sent from either side. This is known as 'backhauling'. During a break, you can continue transmitting data by simply sending messages in two directions. This will also allow you to identify where a problem has occurred. You just need to find the site where the microwave transmission is being stopped.
