Range of the RG Box?

Hello,

I plan to get a U-verse bundle package installed in my house in the near future, but before I place an order I want to make sure that what I'm hoping for will work.

I have a 2 level townhouse.  On the 2nd floor bedroom I have a Telephone Jack and I want to have the Residential Gateway installed there as well as the Total Home DVR.  Downstiars I have a TV that I want a wireless reciever.

Is this scenario possible?  

Thanks in advance.

Matt
