Is any engineering necessary before ordering wireless modem equipment?
Yes. First of all, you must define your radio network properly: 1) Identify where your equipment will be placed and the geographical co-ordinates. 2) Identify the network topology: which points are interconnected. 3) Identify the frequency you will be using, or at least, the band on which it is to be located. 4) Identify the equipment (carrier power, data speed) and aerials (gain and type). 5) Identify the communications protocol and ensure that data speed is high enough. 6) Calculate the radio-link quality: optimal > – 70 dBm at RF port, minimum > – 90 dBm. If you have the information required under points 1) and 2), Farell Instruments’ Technical Support Service can help you define the rest.
