Minimum/Maximum output power values for cell phones

Hi.
i need a help, guys. i am starting design of cellular detector and for calculating RF chains i need to know maximum/minimum cell phone output power values. Maximum output power value is about 27-33dBm depending on technology, but minimum values i can't find.
And if anybody knows maximum output power of basestaiton it will be helpfull too.
Thanx a lot

-5 dbm for GSM (0 dbm target with +/-5 db tolerance)

-50 dbm for WCDMA

...and -40dBm for mobile LTE

For CDMA2000, the max basestation power is about 100W.
