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.

    • While I've been loath to update my Samsung devices past the May 2022 update to keep the Band Selection tool, I note that it looks like Android 14 is going to add Timing Advance for NR to the API.  (Was looking today as I have another Verizon A42 5G now that I'm going to unlock for T-Mobile, and wanted to figure out if I should let it update or not.)  Since I can technically make band changes from *#73#, on the A42 5Gs, I can probably live without the Band Selection tool if a later Android version adds something useful like TA values. I assume SCP will be updated to support that once it becomes publicly available.  The real question is whether or not the phones will support it.  My S21FE and A42 5G devices do on LTE, but I know the S22 and the A32 5G do not support it even on LTE, providing just zero in that field. - Trip
    • The A23 5G appears to support all of the Dish NR bands except n26 which they don't even own yet, and n29 which as SDL can't be logged as far as I can tell.  https://www.phonescoop.com/phones/phone.php?p=6760  I mean, n71, n66, and n70 are there, and those are the ones I'm most concerned about. I know that's not trade press, but I've found Phone Scoop to tend to be missing bands rather than including bands that should be there. I don't really care if it's carrier locked; if I'm buying a device specifically for Dish, then I'm probably not switching it out in the immediate future. - Trip
    • I mapped out the various phone choices to Dish's NR bands.  Used trade press for many of the phones, which can be unreliable.  Just starting with N71, you are down to three phones: Moto G Stylus 5G 2022, Moto Edge+ (2022), Celero 5G+.  Add in the less frequent n66 and you are down to: Moto G Stylus 5G 2022, Moto Edge+ (2022).  The Moto G Stylus 5G 2022 then walks away with the rest of the bands.   A negative is even if you pay cash, the phone is carrier locked for a year.

    • After nearly a month T-Mobile seems to be finally expanding n25 beyond the initial 5 sites they were using. However, it seems to be quite the mess. The three sites near me are all using different size channels. I'm getting a 5Mhz channel that's only using the G Block, a 15Mhz channel that's using the C Block, and a 20Mhz channel that's using C+G, each from a different site all next to each other. Very confusing.
