    Hello Tine,

    It would be surprising to face a high FER with a RxQual (BER) keeping a good value.

    …Unless your problems are not located on the air interface but rather at transmission/synchronisation level …in which case you will probably have a high Drop Call Rate, but then FER is a symptom; not the disease.

    I guess you will never have such a case, because some other indicators, more widely used (customer complaints, drop call rate), will point out the problem before you even have a look at the FER.

    Jane, though wireless telecoms might sound like a “niche” to many people, the aspects of this domain are broad. The documentation that you need to look for will depend not only on the subject that you are interested in, but also from what you already know. As a general practice in this domain, I recommend that you borrow a book (maybe you have telecom engineers in your environment who can lend one) or buy one… though the price seems high (60-100 euro) at the beginning, but it’s worth!

    To me, working on KPIs performance for Radio Access (Air and Abis interface), I find very important some concepts like speech coding (A and Mu laws, or let’s call it logarithmic compression) and source coding (mainly the error-correcting coding which allows to “fix” your frames even if some bit errors occur), even though it’s not needed for my everyday tasks… but it helps a lot to understand better what you will learn or do in the future (if you work in telecoms).

    hello emmanuel,

    1 erlang represents the usage of one channel during 60 minutes.
    So you just have to divide the number of erlang by the number of channels –> how many minutes per hour each channel was used (in average).

    1 erl = 60 minutes

    actually, i did a stretch.

    1 erlang = the duration of the observation period. usually, for BSS elements, it’s one hour.
