It is even more dramatic than that. Analog has some power control levels but the falloff of it is very slow from the center of the cell to the edge. the power levels can step in only 16 levels.

CDMA can adjust the power levels in 1000's of steps. Near the cell site, the power level is down to as low as 10 microwatts. At half the radius of the cell site (7 km), it is only up to about 2 milliwatts. In the last 10% of the cell radius, the pwoer level appraoches the 200 milliwatt level. 50% of the time, the phone is putting out 2 mW or less. Unless you always use the phone at the edge of coverage you will most likely be less than analog by a factor of 100 or more.

Then on top of this, it uses bursts to transmit rather than continuos waves like analog does.
