According to GSM 07.07 Section 8.5, convert from dBm to rssi [0..31]: 0 -113 dBm or less 1 -111 dBm 2...30 -109... -53 dBm [ (113 - s)/2 ] 31 -51 dBm or greater To convert from rssi to bars [0..5] 0 -113 dBm or less 1 -111 dBm 2...4 -109... -53 dBm [ ((rssi * 2)/15 + 1 ] 5 -51 dBm or greater For GSM, I believe the number returned is rssi [0..31]. 0 0..3 1..4 4..24 [ rssi/6 + 1 ] 5 25..n -------------------- Jeff Loucks Work 425-284-1128 jeffryl@sproqit.com Home 253-851-8908 jeff.kim.loucks@centurytel.net Mobile 253-691-8812

3.  03/01/2007, 09:13 AM ahhhh, if I convert my RSSI value of 70 to a dBm level, then use that dBm level in the bars equation, on a 1-5 bar scale, a RSSI level of 70 comes to 3.867 bars on a 5 bar phone. Neat equation. Any math-heads reading who want to pull an equation out of that for 4 bar phones? (wait, does my treo go to 5 bars and i've just never seen it? lol)
