Ensuring 4G networks perform to carrier specifications is an everyday challenge for field technicians. To achieve high-speed operation and reach established KPIs, interference must be mitigated. Time Difference of Arrival (TDOA), a technique for geo-locating RF sources, is a highly effective method to efficiently achieve this goal by making it easier to locate – and subsequently correct – interference.
TDOA can provide a very accurate location estimate (< 100 m) in a short period. To successfully use TDOA, it is essential to understand the type of signals that can be used, how the results depend on the geometry of the measurement, what the sources of uncertainty are and how to mitigate them, and how to know if the answer is meaningful … Keep reading the original blog post here
