Some phones may show either a 1x/3G reading or a 4G/LTE . Performance to RSSI / dBm table prevents automatic ranging from choosing a different setting suggesting the m gets clear. dBm interpretations are a consistent unit of measurement. Then your Rasperry PI, you have to inform MMDVMHost with a RSSI.dat file contenting the conversion of Raw data to dBm levels (linear relationship between the input (raw) RSSI and the RSSI reported to the network), for example : # Raw RSSI dBm 997 -100 1020 -95 1200 -80 The dBm is a power ratio of the measured power as references to one mW (milliwatt). Setting the AGC to a fixed range prevents automatic ranging from choosing a different setting. To facilitate the use of a shared physical channel, a repeater in an IP Site Connect; Capacity Plus or Linked Capacity Plus system, will monitor its RX frequency and will not transmit if the RSSI from signals from another radio system is greater than a configurable threshold. Rscp and Ec/No are the parameters to examine, and some phones may either. This value will give you the estimate of power available at the receiver end (Xbee module). Signal Level dBm. Apple may have tried the same and failed. It can be programmed for anything between -80 dBm and -120 dBm. I'm told 100 and above is good, but 70 might still work well. 18 dBm to 20 dBm on the 5 GHz radio; 11 dBm to 14 dBm on the 2.4 GHz radio; For session based networks: 11 dBm to 15 dBm on the 5 GHz radio; 11 dBm on the 2.4 GHz radio . A dbm of -80 seems to be the lowest power level for which a module can sustain an "acceptable" link. Keep in mind that due to individualities each subscribers reading could be up to 3 dB +/-. Problem is our firmware is SE-modified, so the rest of the source code is probably not the same. Motorola RSSI to dBm One of the more annoying features of many Motorola trunking subscribers (TRBO lines exempt) is Motorola's fondness of utilizing a proprietary RSSI format (generally 0 to 150).
