Hi,

I use the GPRS connection as the backup in my sites in wide network. I have often problems of connectivity, coverage and responses times issues:

i.e:

R1#sh cell 0 radio
Current Band = GSM 900, Channel Number = 96
Current RSSI = -68 dBm
Band Selected = GSM all band
R1#

R2#sh cell 0 radio
Current Band = WCDMA 2100, Channel Number = 10589
Current RSSI(RSCP) = -74 dBm
Band Selected = Auto
Number of nearby cells = 1
Cell 1
        Primary Scrambling Code = 0x78
        RSCP = -78 dBm, ECIO = -4 dBm

R2#

As you can see, the RSSI have not the same value each time and also the Band used is different from site to site (GSM,WCDMA,...).

Does someone can help and tell me with are better performances ? the range of best RSSI ? and the betest Band ?

Thanks you very much.

Regards,

I have this problem too.
