A wireless PBX can be the solution to your problem. Actually you would
not have to buy a whole new PBX, but expand instead your actual
facilities installing radio ports. Several systems based on TDMA or
Spread Spectrum technologies are appearing in the market this year.

For additional information, you can look at:
