Wrong number.

An ANALOG 900 MHz phone is allowed 750 microwatts (3/4 milliwatt).
A DIGITAL SPREAD SPECTRUM 900 MHz phone is allowed at least 80 mW (the
highest I've seen used), though many use much less comfortably.

A hand-held portable cell phone is allowed 600 mW (.6W), while a car cell
phone is allowed 3 W.  A CDMA cell phone typically uses much less.

A 27 MHz "kiddie talkie" is allowed 100 mW, or at least used to be.
