The range specified on any wireless datasheet is the range under optimum conditions and so not easy to obtain, but here are a few tips to help you get the most out of the system.
- Have you got line of sight, i.e. Can you see the wireless units that are trying to talk to each other from each of their installed positions? If you can you have line of sight, if not the radio waves have to go around corners and your range will be reduced.
- How high is the aerial? Get your aerial as high as you can the further the aerial is from the ground and other objects the more clear space the signals have to propagate into and the better the signal will be. The higher the aerial is the less likely moveable obstructions like plant or Lorries will get in the way.
- Most aerials works best point straight up or straight down normally perpendicular to the direction of transmission; make sure your aerial is pointing the right direction.
