    I have some questions on the telephony API - how to interpret signal strength (RSSI), neighbour sets and so on. Anyone out there got experience in this area?

    Which one? iOS, Android, Windows, WTAI?

    Android in the first instance, but IoS to follow. I know there are field test modes so the info is available, just trying to understand variables and structures in order to get similar info into an app

    With Android you'd access that information using:

    CellSignalStrengthCdma
    CellSignalStrengthGsm
    CellSignalStrengthLte

    You'll also need the READ_PHONE_STATE permission to do this (and the MODIFY_PHONE_STATE permission to change anything).

    If you Google for examples on the above you should find some quickly enough.

    Thanks. Those entries do not return items such as the BLER (block error rate), which is what one of the items I am after

    You can get the bit error rate if that's any good?

    That's more associated with LTE, is it not? If so, it might simply be something that isn't yet handled by the API, but will be added later.

    Can you not determine this another way? Like testing the connection?

    weeeeeelll, I am more interested in UMTS (3G and LTE) the BER is more 2G focussed. The BLER is block error rate and is a measure used by the network to figure out how much data can be pushed down the pipe. There may be alternatives but I have seen it even on IoS in field test mode and I'm keen to access it if at all possible

    I've not worked with it before, although I've come across it, so I don't have an answer at hand without spending time researching it, I'm afraid.
