Awarepoint – zigbee-based, mesh, RTLS. If you google at bit, Kaiser has shared a lot of the information about it.

They’ve deployed Cisco for wireless (for public and private), and the AP’s are all below the ceiling, along with what appear to be cellular repeaters. Having the AP’s exposed doesn’t appear to diminish the look at all - after all, there are lots of other distractions on the ceilings such as fire sensors, call lights, etc. What was really interesting is that they didn’t use the system for location tracking of patients/equipment. They had a separate system that used these tiny/flat/thin/flush “night light” looking devices that were plugged into power outlets everywhere, and they formed a huge mesh location network. Amazing.

This is how I see it as well. As the deployment gets more dense with AP’s walls become less of a factor. My other big resistance to this is serviceability. In a Hospital we have Infection Control issues. You can’t just get a step ladder and start poking around trying to find where and/or what happened to your “hidden” AP. Also over time other installers come thru the ceiling and do work so you never know what they may have done to your AP to get it out of their way. Wi-Fi already has too many variables in involved and this would add yet another layer. Thanks.

Coverage from AP’s, be they above or below the ceiling, is highly influenced by obstacle near the AP. For the most part, there are more potential obstacle above the ceiling than below. If you survey with the AP above the ceiling, and install the AP exactly where it was during the survey it should work fine. If, on the other hand, the AP gets installed 1 foot away from where it was during the survey, you could get weak or no signal somewhere you didn’t expect. AP’s installed below the ceiling are less likely to have this problem. In most cases, as long as they’re installed within a few feet of the surveyed location they’ll have the same coverage. Exception occur if the AP get installed next to a large column, or bookcase, but these obstacle tend to be much more obvious to the installed, than light fixtures, air handlers, and ductwork. That said, the more we design for density and the smaller our cells the less important this becomes. If we assume the extreme case of one or more APs located in every room (and also assume we’re not doing something as dumb as setting the AP on top of florescent light fixtures or an HVAC duct), small differences in position above the ceiling are unlikely to have any appreciable effect on network performance. FWIW, except for a tiny number of special cases we keep our APs (or at least the antennas) below the ceiling. It provides more consistent results and reduces the coordination required between the designer and installers.

Ductwork, pipes, etc. affect about 10% of our coverage. We have also tested the newer "in-the wall" devices that could be applicable to your design. We chose Ruckus since a number of their devices, including in-the-wall are immediately meshable if necessary without any work on the controller's part. Meshing has proven handy for us when we have had network feed issues at our dorms. As long as the antenna gets power it will automatically link to an active downlink antenna.

I also don’t have much time or resources to “play” around with the design since it will be in a hospital environment. I am pushing to keep the AP’s below the ceiling but the renovation area is looking to have a “Luxury” feel. Facilities tells me to think “Luxury Hotel”. Hotel wireless is not the same goal as Hospital wireless. I suggested the paintable covers or the 2x2 drop ceiling enclosures. I think they want a “No See AP” look. Thank you for any comments on this issue.
