If the hub, included blasters or remote itself cannot reach all of your devices via IR (line of sight) or bluetooth or wifi (not line of sight), then you will need to buy additional equipment.
Let me try to explain one more time, and you asses your situation and see if it fits.
Remote sends commands to the hub via RF. RF can past through walls, floors, ceilings and furniture, so no line of sight between remote and hub is required. Remote can also send its own IR to devices within its line of sight (the TV in front of you, for example). 99.9% of all RF remotes work this way, not just the Elite. This is essentially the definition of an RF remote.
Hub and blasters blast IR in all directions. Any IR device within line of sight with either of those will be controlled. Devices can usually work off the reflections within an enclosure as well. So setting the hub on one shelf will likely reach devices on other shelves by reflections.
Hub also relays certain commands to certain devices via wifi and/or bluetooth. Those devices, if listed on Harmony's support site as being compatible, will be controlled even if they are not line of sight with the hub. Playstation 4 is an example of one such device.
I just got done replacing my URC MX-850 with a Harmony Elite. I got my MX before URC took their software down off their site, so the first go round was through a home automation company. I've changed out my entire system twice in the last 7 years and didn't want to pay the $95 an hour to have some dude download a setup, so I learned and did it myself. Problem there was going head to head with the original remotes and the MX to program, as URC wasn't updating their database anymore unless you were an installer.
Today, I setup my whole system, consisting of a UN65KS9000, a UBD-K8500, a Directv HR45/500, a Denon 3312ci, a Wii U and a Lutron Grafik Eye lighting controller. The Harmony database is awesome and although it didn't have the Lutron in it, I merely shot the old remote at the hub and taught it the Lutron system. Everything works great and I couldn't be happier. The hub is inside the cabinet on the top shelf, a blaster is on the lower shelf and the other in front of the tv stand. Voilá!
In the brochure, it outlines that the RF will penetrate cabinets and walls, but to what extent, I don't know. I figure if my dual band router penetrates pretty much the whole house with 2.4ghz and 5ghz, the Harmony shouldn't have a problem.
