Hello everyone,

I found that for scanning GSM and LTE there are libraries but now i want to scan 3G CDMA downlink signal. So if anyone knows how to do that than please provide resources. (like any library for 3G scanning using SDR or any other resources which will helpful for scan 3G signal using SDR).

@harshjoshi01 If you are using RTL-SDR rtl_power -f 1800M:2200M:200k -g 40, As 3G usees frequnecy band 2100MZ range. observe a spike in the result and use those frequencies with ./src/cellSearch -s xxxxM -e yyyyM you will get the cell ID(Tower) for the downlink.
