Required number of frequency channels estimation from Work Load

Dear All,
I am new to this forum and new to 2 way radio. But some how, I have to work for 2 way radio system design. I have two enquiries,
(1) Which book is recommended to learn from basic to advance including trunking, system, radio infrastructure design, installation?
(2) For Grade of Service, there is computation for the required minimum number of frequency channels according to work load in trunked radio design. How is the estimation and can have paper or any documents?

HI Batuman,

Wow! You’re in for a treat…

you have decided to go down the path of Erlang calculations… Deep!

there are a number of resources about this.

Try this link to see whether it puts you off.

Also, do the usual and google “two way radio erlang”

Best of luck,
