Have seen many people here ask about the interference related document. Here are good case studies and very helpful in practice for on co-existing the GSM 900 MHz and CDMA 850 MHz systems. The UMTS/PCS co-location scenario is considered.

Spurious emissions are addressed as unwanted transmitter effects; transmitters can generate both discrete (harmonics, intermodulation products) and wideband signals that fall outside the transmit band. Wideband noise and raise the noise floor of the receiver. And possible solutions.

Thx.
I just need it to figure out how to locate the interference source.

hey

maybe this files can help u, but this file is to find interference location based on drive test :)

please find attachment
