WebThe phase of a radio wave corresponds to how far the signal is offset from a reference point (such as a particular time or another signal). By convention, each cycle of the signal spans 360 degrees. For example, a signal might have a phase shift of 90 degrees, which means that the offset amount is one-quarter (90/360 = 1/4) of the signal.

Web17 feb. 2014 · This is a strange sort of question, as in reality the signal will go infinitely far (effectively) however you are really asking at what distance might a receiver be able to pick up the signal. In testing a 2.4GHz signal with a 100mW omni antenna, the furthest distance I could receive a signal with less than 5% retries (802.11b kit) was 2 miles with a … Web23 nov. 2024 · However, one can try and tailor the transmitter signal to give it the best chance of travelling furthest, and this is where choice of signal frequency is important. Generally, a lower frequency will travel further than a higher, because the latter leaks away quicker via capacitance to ground.
