In the quote above it is recommended to set the distance to the furthermost client and close clients are not affected. If we just set it once to our max distance and the timeout is longer at shorter ranges would it affect anything? Timeout value is only used if it doesn't receive the ACK. If it is too short it resends the data and waits again. Please let us know how you go with your test.Īnother thought is the coverage is only changing the timeout value before a packet is considered lost. Your idea of creating a table (Lookup table) is good for an individual solution. I am of the opinion that using signal strength alone will not show a true distance. If you use the following and set different distances, example for 2000 metres Figure the maths used in relation to signal strength the rest is easy. Most mobile devices use wifi signal strength to triangulate your position more accurately than GPS. If there was a way to calculate distance approximately would be better. We use a permanent 4klm wifi bridge for our LAN and it averages a return packet time 1.13ms year round. The time for a packet is relational to the distance not the signal level. Setting the coverage to 5 (~2200m) would not work for those only getting 7-800m before RTH.Īnother thought is to send a few ping packets to/from the AC and using the average time to alter the coverage setting. I am sure they all have weak signal strength reported at their max range. Have tried a few examples but can not get it to work for me.Ĭlick to expand.I don't think we should use just signal strength, as we all know different setups get different ranges. This is the equation I have found to work out distance in metres using freq in Mhzĭistance metres = 10 ^ ((27.55 - (20 * log10(frequency)) + signalLevel)/20) I am ok with scripting but I am not a expert with maths! This is where help is needed. If the idea works he may add it into his program. PapaTita may have already looked in this area an I am not going to re-invent the wheel. I have seen others taking the P3S to further than 2250m so a way to use 6 & 7 might get them further. Magic power uses up to class 5 to improve video based on signal strength. Then change the coverage class to the above setting corresponding to the calculated distance. I was hoping to use this calc to get an estimated distance. ![]() I know there is a math equation that calculates distance from the RSSI signal based on frequency. I have not tried them but believe at longer distances the settings will make a difference. The RC will accept any of the above settings. I could not get the RC to accept the auto setting to enable this but I did find The coverage class can be adjusted. I made a comment in another thread on why Magic Power works in FCC areas due to the ack packet timeouts and remembered there was a patch a few years back that enabled auto calculations. I was bored and thought I would do some poking around in the RC.įound the default for wifi distance calcs on mine are disabled. ![]()
