Hello,

I have been playing with the 433Mhz RF modules from rentron, They are
very cheap RF module that works great within 200 feet.
http://www.rentron.com/remote_control/TWS-434.htm
I would like to increase a little bit the power and would like to
control a robo outside whille being inside. There a window barrier. I
have been told that my modules will not work and would have to go with
bigger power ones, Is more power mean higher frequency ? or just a
stronger module in itself ? Does it have to do with the glass behing a
barrier and the wavelenght should be able to pass between the molecules
of the window and 433mhz is too big ??

Glass is not a barrier. You could try a longer antenna but you may be
violating the FCC rules.
