That's what I was thinking. This would be a lot simpler than having to
detect a specific signal, modulate it by 45MHz an retransmit it.

Would the white noise across the right frequency band confuse the
phone enough to disconnnect or garble the call?

I am no RF engineer, but IIRC, building a broadband transmitter
intentionally is not that simple. Also the noise will have to be above the
signal from the base station transmitter (say 50W transmitter?). I wonder if
it would not be easier to jam the uplink signal as this would only require
the jammer to transmit in the same order of power as the mobile.
