Point-to-point wireless links are an excellent way to connect two locations without the need for physical cables.

However, when transmitting signals over water, signal degradation can occur due to several factors. This blog post will explore the challenges of point-to-point wireless links over water and provide some tips for overcoming signal degradation.

What is Signal degradation?

Signal degradation refers to the loss of quality or strength of a signal as it travels from the transmitter to the receiver. This can happen due to several factors such as attenuation, interference, noise, or distortion. The degradation of a signal can result in poor signal quality, data corruption, or even the complete loss of the signal. Signal degradation is a common problem in wireless communication systems, where the signal needs to travel through various mediums such as air, water, or buildings, and encounter various obstacles that can interfere with the signal. To overcome signal degradation, various techniques such as signal amplification, noise reduction, and error correction are used.

Factors Affecting Signal Degradation: Water is a highly reflective medium for radio waves, which can result in signal loss or attenuation. The reflection of radio waves from the water surface can cause multipath interference, resulting in signal fading and fluctuations in signal strength. Water also absorbs radio waves, particularly at higher frequencies, leading to a reduction in signal strength over distance. Atmospheric conditions such as fog or rain can also scatter or absorb radio waves.

Overcoming Signal Degradation: To overcome signal degradation when using a point-to-point wireless link over water, the following strategies can be used:

  1. Antenna Placement: Antennas should be placed in a high location to avoid obstacles and increase line of sight. This can help to reduce signal loss due to multipath interference.

  2. Frequency Selection: Lower frequencies, such as those in the VHF and UHF bands, can penetrate water better than higher frequencies. Selecting a lower frequency can help to reduce signal attenuation over distance.

  3. Proper Calibration: Proper calibration of the wireless link is critical to ensure that the signal is being transmitted at the correct power level. This can help to minimize signal loss due to absorption or scattering.

  4. Diversity Antennas: Diversity antennas can help to overcome multipath interference by receiving signals from multiple angles. This can help to reduce signal fading and fluctuations in signal strength.

Conclusion: When transmitting signals over water using a point-to-point wireless link, signal degradation can occur due to several factors. However, by following the strategies mentioned above, it is possible to overcome these challenges and establish a reliable wireless link.  Proper antenna placement, frequency selection, calibration, and the use of diversity antennas can all help to minimize signal degradation and ensure a stable wireless connection.
