Hey William, I have a few questions for a followup article:
1) Wired performance: All of these things sport wired gigabit connectivity, but as with wireless we all know that wired performance can have wired bottlenecks and problems of its own. I am sure they are all better than wireless or 100/t... but what kind of throughput are we talking about? Personally (and I know I am not alone on this), I like wireless for portable devices, but for something that never moves like a TV or a PC it is really not that much extra effort to run a line under carpet or through a vent.
-Specifically I am curious to know if any of these routers can run their ethernet in a gang mode so that I can have 2 gigabit lines to a server, and 2 lines to my PC (and 1 line to my wife's PC) so I can have enough throughput to offload all of my HDDs to a central location and have a truly silent PC without having to use a seperate switch or router. I do video editing, and obviously cannot afford 10GbE in the home, so this type of setup is needed to get the 150+MB/s throughput needed for real video editing (until consumer 5GbE or 10GbE becomes available... where is that tech anyways?). I am currently using a wireless G router, and then an old (and noisy) gigabit switch (using 5 ports on a 24 port switch lol), and to be able to consolidate both devices would be really nice.
2) High traffic performance: We all know that G and N suffer once you populate a network with a lot of devices, or have multiple networks congesting the same area. While I personally have very low traffic in my area (very low-tech neighbors), I know a ton of readers live in apartments, or have businesses with a ton of machines, and it would be nice for them to know how many devices you can have before having to worry about a serious performance fall-off. As most devices are still on N it would also be curious to see if these new routers can support more devices on N before seeing fall-off than traditional N devices.
3) Internet performance: I have 'decently fast' internet at my home, but that is still only ~25Mb/s. But when wireless G is at 54Mb/s it makes it rather hard to justify getting anything faster than G for your average home user that is simply using wireless on 1-3 devices for internet access, and there is very little file sharing going on. Are there any real-world tests to show some significant performance boost for such simple 'internet only' uses? Perhaps lower ping rates, or more consistent performance at that 25Mb/s level?
4) Power savings: I think more than anything that 11ac is going to show most of it's usefulness in power savings for future portable devices (and I think that ties in a lot with why they are marketing it as 5G to tie in with the cell network speak of 3G and 4G). I look at my friends phones that are only 1-2 years old, and they have to disable the wifi to get a full day's battery out of the phone because wifi's idle simply takes too much power. Compare that to new phones (or even higher quality old phones) which you can leave the wifi on all day and not have a significant battery issue. Even my 5 year old laptop gains an hour or more of battery life (a near 1/3 life boost) simply by turning off the wifi switch, so obviously the new radios in devices are getting much better at battery life without sacrificing much in the way of performance. Also cell providers like ATT and VZW have a lot of incentive to push 5G on phones and in houses to off-load cell traffic.
Anywho, I guess what I am curious about is if the actual network speed is what gains the battery performance, or if it is merely having a more modern radio which brings such gains. As mentioned already, I am running 11g both at work and at home, and so 'all things being equal' the battery impact of wireless appears to have more to do with how modern the device is rather than the speed of the wireless network. I understand the 'race to sleep' argument, but if your internet coming in is only ~5-30Mb/s then I relay wonder if the end device will be able to sleep much at all. Because no matter if your network is 54Mb/s or 1300Mb/s the slow drip of the internet connection is going to keep those radios awake the entire time the internet is up. So is the 5G battery improvement really going to be from the network speed? Or is it merely going to be a factor of having a smaller and more efficient radio package to begin with regardless of what network it hooks up to?
-Note: this is not the same thing as comparing 3G to 4G/LTE networks where the actual internet speed is faster allowing the device to gets it's job done faster and go to sleep faster. When on a network the internet speed is a relative constant (and almost always slower than 11g), and I am curious if changing the wireless from 11g to 11n/ac provides any battery gain on any given device for a set workload.
Anywho, Great article! My old wireless G router is starting to have troubles, and needs to be reset every 4-6 weeks, so I am really curious about getting either a high end 11n device, or a midrange 11ac device before the year is out. And if I can find one that can last the 8+ years that my current linksys G router did then all the better! We don't see a lot of wireless articles here on Toms, and it is something that is increasingly important as people put heavier workloads and take bigger machines off of wired connections.
