Der TechMode bei Sony Ericsson ist eine Art Netmonitor in abgespeckter Form. Man bekommt CH, C1, LAC, Sprachcodec und 6 Nachbarzellen angezeigt.

Mit *585*0000 und dann "Anrufen" bzw. *585*0000# "Senden" drücken wird der Techmode aktiviert.
Auslesen kann man dann die Daten über die Shortcuttaste (die direkt über dem Joystick) und dann Techmode anwählen; oder über Menü - Optionen - Verbindungen - Mobilfunknetze.
Durch längeres Drücken der Zurücktaste wird der Techmode verlassen. Ganz kann man ihn mit #585#0000# und dann "Senden" deaktivieren (bzw über die Shortcuttaste und dann "Anw.Ende").

Getestet bei: K750i (D750i auch!), V600i, K700i, K500i

Hinweis: Bei gebrandeten Handys kann es sein das es nicht funktioniert!

Hier eine kleine Erklärung zu dem SE TechMode:

GSM Channel ------------------------- A BBB CC -DD EEEEF GG HHHH I JJJ K LL MM NNN OO PP QQQ RR SSSS TTT -TT UUU -UU VVV -VV WWW -WW XXX -XX ZZZ -ZZ In stanby mode shows only bold marked parameters. A - Current type of service: * B - BCCH - Broadcast Control CHannel - Standby Mode * S - SDCCH - Standalone Dedicated Control CHannel - Used fo registration, autorization and refreshing status. * F - Frequency Hopping - TDMA frames are transfered at different frequencys. * T - TCH - Transfer CHannel - Data transfer/Speaking Mode. BBB - Number of current channel: * 001...124 - GSM 900 (124 channels) * 512-885 - DCS 1800 (374 channels) * 974...1xxxx - EGSM 1900 * 9999 - No Signal. CC - Number of current channel on a current BS (Base Station) -DD - Recieve level (RxLevel): -40dBm...-117dBm. -40dBm is the strongest signal. EEEE - Cell ID F - Cell Sector Number GG - DTX HHHH - seems like another channel (?) I - Timeslot number: 0...7 One of the eight channels which are used to transfer TDMA traffic. On 0 channel is transfered control information: BCCH, SDCCH, etc. Other channels are used for traffic. JJJ - Transmitter signal level, 0...34 dBm K - Bit Error Rate - number of errors, 0...7. 0 - No errors. When more than 5, sound is being lost frequently. RxQual table 0---BER < 0.2 (%) 1---0.2 < BER < 0.4 2---0,4 < BER < 0.8 3---0.8 < BER < 1.6 4---1.6 < BER < 3.2 5---3.2 < BER < 6.4 6---6.4 < BER < 12.8 (Half of packets are lost here) 7---12.8 < BER LL - Timing Advance. 0...63. With this parameter it is possible to calculate distance to BS using the following formula: L=1.11 x TA/2, where L is the distance to BS, TA - Timing Advance. In GSM standard max distance from BS is 35.2 km, so one number here is rouhly 550 m. Timing Advance: 0; 1; 2; 3; 4; 5...63 Distance to BS: <550 m; 550-1100 m; 1100-1650 m; 1650-2200 m; 2200-2750 m; 2750-3300 m ... 35.2 km. MM - No Info. 0...31 (maybe it is number of lost packets) NNN - Rate of speech codec: * HR - Half Rate * FR - Full Rate * EFR - Enhanced Full Rate OO - No Info. 0...95 (seems like RxQual) PP - No Info. 0...83 QQQ - Network Country Code (NCC) RR - Operator Code (MNC) SSSS - Local Area Code (LAC) TTT -TT UUU -UU VVV -VV WWW -WW XXX -XX ZZZ -ZZ Numbers & Rxl of the best alternative channels. -------------------- GSM AMR -------------------- --- --- --- D ---- U ---- -- yinyang.gifY ZZZ - - The first three lines are same as GSM Channel, the last two are different. yinyang.gifY - C1 (Correction 1) ZZZ - C2 (Correction 2) the fewer the difference between C1 and C2, the better. The best is: C1=C2. Also it is possible that C1=C2=RxLevel
