# Shannon - Hartley Theorem

Let's consider the Shannon - Hartley formula for the channel capacity $$\C\$$:

$$C = B \log_2 (1 + S/N)$$

I have two doubts about it:

1) is it correct for TDMA, FDMA, or CDMA? And why?

2) Can a variation of the dimensions of the radio cells (base transceiver stations) reduce/increase the value of $$\S/N\$$?

• For Q1, D in those acronyms is for division. So each protocol only divide channel capacity for each user. – Rokta Sep 25 '19 at 6:38
