WiFi, Cellular & Download Booster
At MWC this year Broadcom announced its BCM4354 802.11ac 2x2 MIMO WiFi combo chip for smartphones/tablets, which found its way into the GS5. The result is a smartphone capable of negotiating with an 802.11ac AP at 867Mbps, and transferring data at up to 436Mbps.
Although peak performance is nice, there are also power benefits to being able to transfer data quickly over WiFi (race to sleep applies to network interfaces as well).
The Snapdragon 801 features Qualcomm's integrated category 4 LTE 9x25 modem core. As I mentioned in our power analysis, Samsung also chose to include Qualcomm's QFE1100 envelope tracker (just like in the Galaxy Note 3). The GS5 is also the first flagship Samsung device to include support for 2 carrier aggregation on supported LTE networks. Samsung doesn't appear to be using Qualcomm's antenna tuner or any other RF360 components in the Galaxy S 5.
Seamless transition between network interfaces is one component of Qualcomm's vision of the future of connected devices. The problem is presently more of a software one than a hardware challenge. Samsung is beginning to explore software abstraction of underlying network interfaces with the GS5's software stack. There's now an option to prevent transitioning to WiFi networks that don't offer an improved network experience compared to your broadband connection. I haven't had a ton of time to test this feature out yet but it's something I plan on messing with more over the coming weeks.
The other big feature is what Samsung is calling Download booster. If enabled and under the right conditions, download booster allows you to combine WiFi and cellular network interfaces to accelerate large file downloads. All you have to do is enable download booster and you'll get a notification if it's active and working:
Download booster uses HTTP range requests to divide up files between the two network links. The feature can migrate data sessions from one link to another (WiFi to LTE, LTE to WiFi). Supported apps include the Play Store, YouTube, Facebook photo/video downloads, Samsung apps and standard HTTP web browsing (both Samsung's own browser and third party browsers). FTP and UDP aren't supported, nor is HTTPS.
There are other limitations as well. File downloads smaller than 30MB won't trigger download booster. Similarly, if one of the interfaces is substantially faster than the other download booster won't activate either. My home internet connection can regularly pull files down at 50 - 60Mbps, compared to < 10Mbps for T-Mobile LTE. When I was getting ~7Mbps over LTE and 50Mbps over WiFi, download booster automatically turned itself off. If I throttled my home network to 22Mbps however, download booster did its thing and gave me a healthy combined download speed of 30Mbps.
Download booster is a neat feature, although of limited use for those of us without truly unlimited high speed data plans. That being said, if you need to speed up a download in a pinch it's a great way to do that. I'm often at a press event wanting to download a benchmark onto a device as quickly as possible, usually without great WiFi or cellular reception - I can see download booster being very useful there at least.

What r u talking about. I never faced any issues on My Nexus 5 regarding software or hardware. RGB is real pixel and not RG BG samsung cheap grossly over saturated colors. Nexus 5 is the best screen/ touch till date and yeah nexus 5 delivers better low light performance and with OIS better videos than Galaxy S4. And yes if being cheap is an draw back then yes Nexus 5 is Cheap. You better face reality.Serroots - Thursday, April 10, 2014 - link
I'm sorry but I truly hate the N5 screen. I've got an S4 and friends have the N5. Every time I pick it up I immediately notice how washed out the colours look. It's a great phone don't get me wrong, but I hate the screen.twebber - Tuesday, April 8, 2014 - link
Yeah I have like 74GB of storage space because of my micro sd card, lets seen your nexus do that.bleached - Tuesday, April 8, 2014 - link
I have about 150Gb of storage available on my Nexus 5 with 50Gb free.hero4hire - Thursday, April 10, 2014 - link
Cloud storage? stop. I have 100 TB of storage on my iphone 3gs because it has a web browser too...Chaser - Tuesday, April 8, 2014 - link
Nexus 5 battery life is paltry compared to the S5. And that's far beyond "basically". So no we're not all lost sheep and you're the brilliant, informed consumer.jmunjr - Tuesday, April 8, 2014 - link
The Samsungs have user replaceable batteries and external SD card slots. Those features alone make their phones MUCH better, for me at least.Until a phone can be recharged in less than 15 minutes I will continue to buy phones that have user replaceable batteries. I swap batteries several times a week. I never have to worry about charging. I never have to wait more than time it takes to shut down, swap batteries and boot up.
The SD card slot is another nicety. Though not a deal breaker if it is missing, it sure is nice to have extra storage beyond what the phone makers offer among other conveniences of transferring files to devices that aren't networked..

I agree about the removable battery. That's why I won't buy a M8 if I were interested in choosing between the S5 and M8.comomolo - Tuesday, April 8, 2014 - link
For such a rant about others idiocy, you don't seem to have very solid arguments, just a pretty subjective opinion.Lack of microSD and replaceable battery is a no go for many people (including myself) against the Nexus. Also, besides all the FUD around "tech" sites, AMOLED is just a much better technology for any screen and especially useful on mobile devices... if it was properly leveraged, which amazingly Samsung does not, but a knowledgeable user can. Even if you don't take advantage of the low consumption of dark themes on OLEDs, you get the best screen out there with the S5, according to DisplayMate.
Now why exactly is the Nexus 5 so "superior"?
goobersnatcher - Thursday, April 10, 2014 - link
The N5 isn't superior by any measure other than the promise of fast OS updates. However, when you take in the huge "bang for the buck" .......... the N5 is very compelling! The Moto X, very nice when it was on sale. You can buy a N5 and a nice tablet for the purchase price of a S5. The value for many for the $600.00+ price for a S5 ......... is prohibitive. Of course I respect those who value having one of the best ...... if that means that much! It's just "different stroke for different folks"!
