Okay, naughty I know, but I need your help. Got an exam later today, and one of the bits of theory I'm struggling with is this;
It's related to the cell re-use pattern within a perfect "hexagon" shaped GSM cell.
The question:
"Prove that for a hexagonal geometry, the co-channnel reuse ratio is given by Q = sqrt(3N),
where N = i**2 + i*j + j**2."
Cosine law is used, but I keep getting stumped.
So, any bods out there ?
This might help understand what I'm chewing on:
