    Hi,

    I'd like to research the field of cellular network and cellular chips.

    I started with Wikipedia but it seems very complicated and was wondering whether you got any other good sources which can give me good insights about this field.

    Thank you :)

    Try some of the chip manufactuerr's wesites such as http://www.maxim-ic.com

    The entire system is rather complicated so best of luck.

    Thank you very much.

    I have a question about the subject please.

    It's said that if you reduce the power (radius) of each cell by 2, then you get 4 (2^2) times more channels.

    Why is the quadratic relation?

    Possibly something to do with the inverse square law?

    Thanks Tom,

    I still dont see how the channels' number gets involved in this.

    Kind of like a CB radio had channels.

    The whole system is a mess to try and understand what with all the different carriers sometimes sharing towers and such, and the way the radios have to switch channels if you move into a cell where the one you were on is alaready in use.

    I know it's complicated but I really want to understand it.

    Is there anywhere (forum, article) I can consult and read about it?
