    Hi Experts,

    1)How can we defive the UTILIZATION of the cell??

    2)We can see utilization over 100% in cell’s.
    i.e 150 %, 180% means over 100%.
    Till 100% its understood that the all TCH slots are busy.
    What if above 100??

    Hi ali baba,

    perhaps by “utilization”, they mean “load”.

    in this case :
    tch utilization = tch traffic (erl) / cell capacity (erl)

    capacity depends on erlang B law.

    in this case, the traffic can exceed the capacity, leading to > 100% values.

    Hi Ali,

    150 and 180% very well means that yuo are supposed to expand your TRX or plan a new Cell.

    Hi Ali,

    Th utilization is calulated on a basis taking the GOS=2%. And when it shows utlzn more than 100% means the GOS is been reduced from 2%.

    Hence u will have quality issues.

    Hi Prabeen
    Are you sure when utilisation increases ,the GOS decreases??

    Please rethink.
