I'm considering installing nest protects in each unit near the rear egress to alert of the fire escape is compromised by fire. My guess is floor to floor wireless communications may not work too well. I'm thinking about cleaning up the communications runs in the rear of the building. The cable company did a shoddy job of hanging cable for TV services in the 80s. It seems a good time to add communications conduit and run more modern cabling. As part of this, I'm considering running LMR 600 cabling on the exterior brick wall to act as 2.4Ghz communications wave guides. I was thinking make a loop but break the loop at each floor with a 2.4Ghz wilkinson power divider . Then bore a hole into each unit and install a 2.4Ghz patch antenna pm each rear interior wall. Each unit would then install a Nest protect on the ceiling from the patch antenna. The ring or loop topology I think gives a bit of redundancy. Thoughts on if this would achieve the goals of supporting nest protect communications for such a building?
