0,OKTime needed for processing newly uploaded measurements
After uploading new measurements to the OpenCellID community servers they are added to our waiting queues and processed in the background. We aim the real-time processing, but maximum time depends on traffic on OpenCellID servers. Current throughput of our servers is around 15000 measurements per second.
Measurements are processed in 3 steps:
- parsing and filtering raw data
- updating measurement statistics and storing measurements in the database
- updating existing cell towers information or adding new cell towers to the database
Our waiting queues for cell towers and for measurements are independent, so you can see your measurements in the OpenCellID database but related cell towers might be not updated yet. This means that if you upload a measurement of a cell tower that was not in the database before and the waiting queue for cell towers has some data to process, you have to expect some times (usually few minutes) until the queue delivers the newly uploaded cell tower information.
Upload notes
Optional measurement fields can be omitted. For CDMA observations, mnc, lac and cellid can also represent sid, nid and bid respectively.
