2-4 LGCell Equipment
The Main Hub also receives signals from the Expansion Hubs and reconverts them
back to the cellular or PCS band for transmission on the uplink channel (mobile) to
the macrocellular base station (BTS) or microcellular base station (MBS).
The Dual Band 900/1800 Main Hub is shown below.
Main Hub Features
