How to sniff 2G/3G/4G signals

Dear ARM friends,

I want to capture 2G/3G/4G signals, from mobile phones or stations, by mobile phone or PC.

I want to use signal strength for indoor positioning.

It is relatively easy to capture WiFi and Bluetooth signals by mobile phone or PC.

If you have any suggestions, please tell me.

I want to hear from you!

  • I should be a hacker to download my program on the neighbour smartphones, and I will try.

    I still have other questions.

    (1) The TcpDump for Linux can sniff the WiFi packets, which include RSSI, on my PC. The TcpDump for Android can sniff the WiFi packets, which don't include RSSI, on my smartphone. The TcpDump for Android is found from the Internet, and it may have limited functions. Is there a newest version of TcpDump for Android on the Internet, which can provide with RSSI?

    (2) On my smartphone, I can use shell command "TcpDump -i wlan0" for WiFi. But what shell commands can be used for Bluetooth and 2G/3G/4G?
