    If you were deploying all new APs today, N or AC?

      It could be the antennaes but my understanding was that the 2.4GHz channel on AC routers had a stronger signal than your standard N routers.

      I believe that that is true too. However, it cannot use that unless both sides of the connection are AC. Otherwise the signal might reach the laptop or phone, but the signal from the phone can't get back to the AP.

      Not at all. It's still an N signal, just a higher powered one. It's like what happens if you put higher octane gas in your car. Your car may normally take 87, but if you put 93 in, you'll have more kick and slightly better MPG from the same car.

      Higher power means nothing. Nor is that related to buying an AC AP, is related to the specific model you bought.

      With APs its better to use lower power (hence why we use minium RSSI in deployments) as it keeps edge devices from slowing down everyone else. A device that can connect but can also send back slowly will slow everyone else down. This is the case with things like the UAP LR and the reason they aren't a good choice for connecting endpoint devices.

        Yeah, I can agree with this. If you're just connecting multiple switches together that are stacked in a rack, copper is fine. But between buildings? Fiber would make sense.

        Assuming buildings are farther apart than copper will handle. Even between buildings copper can be fine when the buildings are close.

          If your goal is higher powered N, buy a better N AP, not an AC AP.

            There isn't the EM noise issues, though there won't be any EM noise with properly selected cooper either.

            Because fiber comes with loads of caveats, the biggest ones being cost. Unless you are dropping packets with copper, fiber has literally no performance or reliability advantage. If you are dropping packets, you need to address what is wrong with your copper. EM should not impact you under normal conditions.

              Yes, but if you can gain the range benefit and also have the AC ready to go when your computers start coming with AC cards, why not?

                Because that's not a feature of AC. It's a feature of a long range AP. 2.4ghz on a N AP and an AC AP is exactly the same.

                  We just discussed how range does not improve.

                    Remember, investing today in technology for tomorrow means you pay a premium for that technology. What if, by the time you are ready for AC, the next thing is out. Will you invest again in something that you cannot use? You are just continuously losing money doing that. You need a tangible benefit to your investments, especially when they are large (in percentage, normally.) AC is not cheap compared to N, it's not like a couple extra dollars. It's real money that you lose, money that could have been banked and used to buy even better stuff when the right time came and a need existed.

                      On topic: If I am going to deploy APs today, I would only recommend AC based units.

                      None of my clients lease hardware They purchase it. This hardware will be in place for 6+ years unless some other business need forces it to be changed before that. This means that all hardware purchased needs to be thought about with implications to future usage.

                        I think arguing that because AC isn't an official standard yet so not using it doesn't make sense is a foolish way to go about it considering it was what, a decade before N became an official standard?

                          It was only about 6-7 years. But, I don't think that's the issue it's deploying something that's overkill for your needs. If you really need those improved speeds go for it. If not your wasting money and may never need it. Along with the fact that by the time you do need it something may have replaced 802.11AC and you spent more on your last deployment just to have to upgrade it again to meet the needs.

                          Most do not need the benefits of AC. In a medium size deployment AC will easily cost tens of thousands more. Also in deployments you have to consider you have less room for interference (and more chances of it) with a 256-QAM Constellation of AC.

                            Any new deployment that is going to need APs will also mean there is very likely newer hardware onsite.

                            FWIW, AC is active and in use on the few AC capable APs I have installed so far.

                              I will agree with you on this point, for sure.

                              You are just continuously losing money doing that. You need a tangible benefit to your investments, especially when they are large (in percentage, normally.) AC is not cheap compared to N, it's not like a couple extra dollars. It's real money that you lose, money that could have been banked and used to buy even better stuff when the right time came and a need existed.

                              That depends on the brand names you are talking about... and at what scale. If you are going to buy 100 Wireless N for a total of $230k, an additional $50,000 is quite a chunk to go from N to AC. However, I think we are starting to get close to the end of life of Wireless N (we're not quite there yet) -- in the sense that most new laptops and devices sold this year come with systems that work with AC, and N (and even G, in dual rado setups).

                              Since the newer AC Units are backwards compatible with N on the 2.4 gHz band, it makes sense to me, to upgrade to get the extra processing power of the AC access points since they are both firmly planted in that future looking, yet backwards compatible limbo, if you will.

                                  True. But are you planning to upgrade to PoE switches for your APs anyway? There isn't that much difference in cost these days. You could get some refurbished managed PoE gigabit switches if you needed too. Have 100mbs uplinks will also be a big limit on APs, Servers and routers and switch uplinks if not done with stacking cables.

                                    I did a quick search (and I do mean quick, before lunch) at HP switches. It looks like their 1800 series only offers POE for half of a 48 port switch, would is worthless to me. I'd have to get two 24 port switches instead (and actually I'll need three in two buildings since I'm over 48 ports in use).

                                          Correct me if I'm wrong, but uplinks on these types of switches have been gig or better for the past decade, so I'm really not considering a 100 Mb uplink.

                                            any concerns with wattage per port or is it just a handful of phones mixed with other non-PoE stuff?
