Using low-noise amplifiers
That receiver sensitivity seems awfully poor to me, are you sure you're reading it right? 

Based on this, you should add ~ 50 dB of gain to the front end. You should also add some filtering between the amplifier stages to make sure that out of band signals don't swamp the receiver. 

The first stage will determine the total noise figure. If you have a 23 dB gain stage with 1.2 dB noise figure, that will set the total noise figure of the receiver at 1.4 to 1.6 dB. You should also look at linearity requirements, as there are paging networks at 928-932 MHz in the US that are running at pretty high powers.
