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.
