Client has tasked us with finding a reliable cell repeater setup for this cliffside bunker of a home.
Level of difficulty is we have to work with the existing cabling, house is impossible to retrofit. Concrete+ steel + venetian plaster + the equipment room is a story and a half below grade, under the driveway (yes, really).

What I have to work with:
Roof: one RG6 coax, one cat6
Demarc: One RG6 coax, 2-3 cat6
Exterior: Several cat6 stub outs at various places on outside walls (I went heavy on camera locations during prewire).

Distributing signal once in the home can be done via the existing, unused coax distribution or one of many unused cat6 going to touchpanel, WAP, tv and lighting control locations.

Budget is not so much of an issue, functionality is a priority. Provider specific hotspots (M-Cell) are not really what is being looked for.

Ideas?
