The internet has become a necessity for modern-day life, and there are still many regions where it is either unavailable or unreliable. Microwave internet links provide a solution to this problem by establishing a high-speed internet connection over long distances. Microwave internet links operate by transmitting radio signals between two antennas, creating a direct line-of-sight connection between two points.
Setting up a microwave internet link may seem daunting, but with the right equipment and knowledge, it can be done with relative ease. In this step-by-step guide, we will cover the equipment needed, how to calculate the link budget, and how to set up the antennas and configure the equipment.
Equipment Needed
Microwave radios: Microwave radios are the heart of the link and are responsible for transmitting and receiving the radio signals. They come in various frequencies, ranging from 6GHz to 80GHz, and have different capacities, which determine the amount of data that can be transmitted.
Antennas: Antennas are the physical link between the microwave radios and are responsible for transmitting and receiving the radio signals. There are two types of antennas: directional and omnidirectional. Directional antennas focus the radio signals in a specific direction, while omnidirectional antennas transmit the radio signals in all directions.
Mounting hardware: Mounting hardware is used to secure the antennas to a mast or tower.
Cabling: Cabling is used to connect the microwave radios to the antennas.
Surge protection: Surge protection is used to protect the equipment from electrical surges caused by lightning or other sources.
Calculating the Link Budget
Before setting up the microwave internet link, it is essential to calculate the link budget. The link budget is a calculation that determines the expected performance of the link, including the signal strength, signal-to-noise ratio, and link availability.
To calculate the link budget, you will need to know the following:
Frequency: The frequency of the microwave radios.
Distance: The distance between the two points.
Antenna gain: The gain of the antennas.
System losses: The losses in the cabling, connectors, and other equipment.
Transmit power: The power output of the microwave radios.
Receiver sensitivity: The minimum signal strength required for the microwave radios to receive the signal.
Once you have these values, you can use a link budget calculator to determine the expected performance of the link.
Setting Up the Antennas
Once you have calculated the link budget, it is time to set up the antennas.
The following steps outline how to set up the antennas:
Choose the location for the antennas: The location of the antennas is critical and should have a clear line of sight between the two points. It is also essential to consider the distance between the antennas and the availability of power and internet connectivity.
Install the mounting hardware: Install the mounting hardware on a mast or tower at the chosen location.
Install the antennas: Install the antennas on the mounting hardware and connect them to the cabling.
Align the antennas: Align the antennas to ensure that they are pointing directly at each other. Use a compass to determine the direction of the other antenna and adjust the alignment until the antennas are pointing at each other.
Configuring the Equipment
Once the antennas are set up, it is time to configure the equipment.
The following steps outline how to configure the equipment:
Connect the microwave radios: Connect the microwave radios to the cabling and ensure that they are powered on.
Configure the microwave radios: Access the web interface of the microwave radios and configure them according to the link budget calculation. This includes setting the frequency, transmit power, receiver sensitivity, and other parameters.
Test the link: Once the microwave radios are configured, test the link by sending and receiving data between the two points. This will help you verify that the link is working correctly and that the performance meets your expectations.
Monitor the link: After the link is set up and tested, it is essential to monitor its performance regularly. This includes checking the signal strength, signal-to-noise ratio, and link availability. Monitoring the link will help you detect any issues early and take corrective action.
