the
best means different things to different people. here's my take. it's what i've done:
0. choose where you want your 'network closet'. it should be centrally located. your router, switch, and possibly server(s) will go here. pick a spot that's easy to run cat6 to and from. also, your ISP uplink obviously needs to be accessible here.
1a. using common sense,
identify spots that would be good for access points. for starters, count on at least one access point per floor.
1b. of those spots,
focus on the ones that you can easily run cat6 to.
an aside:
the cost difference between cat5/5e and cat6 is negligible. if you're going through all that work to run cable, you're an idiot if you run cat5. ESPECIALLY if you're buying new cable. which cable? get solid (not stranded) because most IDC technologies are designed for it, and it can be a bit more compact and durable. also, don't be a cheap ***. get copper (not copper clad aluminum).
2. decide what system you want to use. use cisco if you're familiar with it and you're rich. if you want something almost as good but much more reasonably priced,
use Ubiquiti UniFi. for your environment, i suggest these specific products:
- router: USG or UDM-Pro
- switch: US-8-150W
- access points: nanoHD or UAP-IW-HD-US (this is kind of a nice product. it's an in-wall AP (sits in a 1-Gang Electrical Wall Box), and it also gives you a 4-port gigE switch right there if it's a spot you want to plug wired devices into).
3a. adopt the APs in your controller and
set them to low or medium Tx power, depending on your guesstimated AP density.
3b. after
familiarizing yourself with their beam patterns,
test mount your APs in the spots you selected. don't run cat6 yet. just power them up via PoE at nearby wall outlets. you can use masking tape to stick them to walls or ceilings. you can also tape them to a piece of wood and lean that against walls like this:
3c. conduct a wifi survey using software like
netspot to create various spectral heat maps of your environment. use them to evaluate your location candidates for your APs. look for dead zones (especially in 5GHz band) and sources of interference.
3d. adjust the AP locations, tweak Tx power, add/remove APs, and conduct more surveys as needed until you're satisfied with the results. remember that sometimes, rotating an AP by 90° can make a difference, so if you just need a small tweak, try that out. it can sometimes be an easy fix. this is an iterative process!
4. when you're happy,
run cat6 from your network closet and install your APs.
5. the hard part is over. crack some beers and
install your network closet gear. terminate your cable runs by punching down into a patch panel and mount your switch and router on something pretty. maybe a nice piece of wood or a network rack. then set up your unifi controller. based on your survey data from before, tweak Tx power and select appropriate wifi channels.
hope that helps someone (i bet it won't
