Qualcomm debuts 802.11ac on it new chip = faster WiFi

You've probably read how the carriers want to offload traffic from the network onto WiFi. Now Qualcomm will make the experience more pleasant. Qualcomm has tested VoLTE and graphic inerface on its S4 chip and now its integrating the new WiFi chip onto the S4. This is a refinement from the old standard and will utilize less crowded airwaves. So when the carries kick you off the network, just enjoy fast speeds at home or at your local hotspot.

Qualcomm bringing super fast WiFi to mobile devices

 

Over the past few weeks, we've seen some impressive things from Qualcomm, or actually, we've seen the Snapdragon S4 a number of times, but each time it's just as impressive as the last. First, we saw the S4's graphical benchmarks, then VoLTE on the S4, and finally more benchmarks of the S4. Now, we're learning that it won't just be the GPU and CPU that will be speedy on the S4, but the WiFi as well.

It turns out that Qualcomm is integrating a combo WiFi/Bluetooth/FM chip to the Snapdragon S4 and other 28nm Snapdragon chips. The WiFi in that combo will be 802.11ac, which is a refinement of the 802.11n standard that runs only on the 5GHz spectrum band and not the extremely crowded 2.4GHz spectrum. This means WiFi data speeds up to a theoretical max of just under 500Mbps on a single link, but given the right setup, it could offer speeds much faster.

We'll have to see what kind of real world speeds it gets, and we'll likely get some demos at MWC.

Even 802.11n is overkill for phones. Most phones only support 1x1 sgi40 on a 20mhz channel. Which means the fastest handshake is 65 megabits while your laptop is connected at 300 megabits on 40 mhz channel. If of course your router and wireless card are set to use 40mhz which most routers are not.

Mine is set at 40MHz on both my N at 2.4GHz and my N at 5GHz. It's 20MHz on my G. I have a NAS that I use to store music and video. I keep it at 40MHz so I can easily stream from my NAS everywhere in the house, to TV's, laptops and smartphones.

    • Luckily, that hasn't arisen in my area where I am, aside from having B14 (well, ALL of AT&T signal) not work at all in Coosa county, Alabama. I wish there was a service for first responders that would go to ANY available carrier, provider, etc..and in the absolute worst case scenario, would give us service. I've been on an ambulance, trying to find an address, and my driver actually had to pull over and we pulled out a map book and tried to find the road using the "old fashioned way".. and that takes valuable time away that sometimes may be vital to someone surviving. BUT, I will say that I've only seen that in Coosa county... both my Tmo and AT&T phones had zero service and I couldn't get GPS, and neither could my driver (VZW service). Maybe satellite will help with that in those times where that occurs.. but that's an extreme example.     Edit to add: Let me add some context to this.. Coosa county isn't regular coverage area for my job.. so it's not a regular thing that we are dispatched to Coosa county.. and actually, there's been a change and that county now has it's own ambulance service that operates.. so the only time we might receive a request is if it's a multiple casualty scenario, or it's a transfer going home from our contracted hospital.  The way that reads above, it may seem like we are just out without some sort of GPS gadget to direct us on where to go, but for the most part, we know our coverage area pretty well. Dispatch can also give us cross streets for reference inside our coverage area (and our home county). Coosa just isn't a regular area for my job to run in. 
    • "Priority" doesn't mean "exclusivity."  When emergency services don't need B14, AT&T can use it for everyone else.  The trade-off is that when it is needed for emergency services, they not only get all of B14, but they have also arranged for priority on the rest of the AT&T network as well.  Beats having spectrum sitting unused most of the time and then not having enough when disaster strikes, as it could be without a partnership with a wireless company like AT&T. - Trip
    • I've wondered if being on the first responder plan has the priority over other 'regular' lines in the same way firstnet does (or, supposed to do with B14...I've seen normal customers on AT&T hit B14 so it's not {specifically} for Firstnet only)...  
    • T-Mobile prices people pay are all over the map. The free lines are key, so take them if ever offered again.  Your priority level would be a key factor for your price.  Only T-Mobile would know the average prices people pay.  Samsung has been offering very good deals at time of new model introductions so I have gone that route for factory unlocked, which allows me to also have a Verizon priority MVNO for when T-Mobile signal fails or I manually override.
    • I also wanted to post a speed test result.. I only do these once in a while from my home area because we are gonna be the last to see changes, like load balancing.  Right now they are digging all over the place for fiber installs, so I'm not sure what the hold-up is on making the upload speed a little more in-line with download speeds, but here is the most recent from my area:   https://www.speedtest.net/my-result/a/10133670525
