When testing cell sites across the world, it is very common to discover “illegally” transmitting devices,
which result in significant interference to the network. On a project we ran in Asia, we came across a number of illegally transmitting devices which had massive implications on local networks, decreasing cell site performance significantly. The interference sources fitted within 3 categories including RFIDs, Repeaters and Narrow Band CW interference.
To resolve these issues and improve networks, we had to arrange to have the illegal transmitters removed. This was often a lengthy, costly, and complex process.
However, after resolving the RFID, Repeater and Narrow Band interference, we were able to drastically improve and enhance network quality.
