CDMA2000 licenced in 800 bands may effect on 900 Mhz bands
OK. No CDMA network in Nigeria, Just 2G, 3G and LTE with 700MHz and co
Ok sorry. What about jammers…? Does your customers live near a military area or governmental buildings or anything like that?
Can you give me the details of network condition like number RSRP and RS SNR?
After optimization has been completed, RSRP value is -96dbm and SINR 3db

Use professional scanner with:
- log file for analysis;
- decode L3 message, for PLMN etc;
- high sensitivity (-134dBm, RBW=1KHz, when scan speed is 3000MHz/s);
- fake BTS checking (an scanner can found the clock tolerance of each cell);
- with GPS and GPSDO synchronization;
Dear can u explain it Why and How ? it will be more helpful for me thanks in advance
Unwanted transmitters are pervasive in today’s mobile networks, degrading network capacity and reducing subscriber QoE. With the densification of cells and the deployment of emerging standards with higher-order modulation over legacy technologies, the RF environment is becoming ever-more complex making networks increasingly susceptible to interference and therefore interference hunting is a key issue for mobile network operators and regulators.
External interference can originate from a licensed or non-licensed radio transmitter. A few dBs of reduction in signal to noise ratio at the receiver dramatically impacts network capacity with subsequent loss of revenue and subscriber QoE, requiring operators to hunt down interference quickly.
Thankfully, scanners can automatically identify unwanted transmitters and spectrum analyzers or receivers, together with a direction-finding antenna and sophisticated software, can automate the process to locate interference.
