Over the course of the last 32 Years, I have witnessed and conducted maintenance on countless wireless links. My experiences have shown that many links are not properly aligned. In the beginning, we had to do the math to figure out what the Receiver Signal Level (RSL) should be. Now, we just need to plug in the numbers using link planning software. As helpful as this may be, it is only part of the process. Both antennas need to be aligned vertically and horizontally to achieve the correct RSL. It is estimated that 40% of the antennas deployed are misaligned. This statistic is not shocking news to me and I believe there is truth in that number. If you think you have a problem with your wireless link, please consider giving Caltuck a call to rectify any RSL discrepancies that can cause intermittent transmission.
