4G Networks Tested: WiMAX vs. HSPA+
A look at 4G and "4G speed" networks currently being deployed in the US; how Sprint's WiMAX technology compares to T-Mobile's HSPA+ technology.
AD article continues below...
Today, America's first 4G phone goes on sale. We just published our
in-depth review of the HTC EVO 4G, but the other half of the story is the 4G network on which it runs. How does Sprint's shiny new 4G network - which uses WiMAX technology - actually perform?
Also making waves these days is T-Mobile's claim that its new HSPA+ network offers "4G speeds". How accurate is that statement, really?
We set out to answer those questions by conducting extensive testing in Philadelphia, one of the few areas where both technologies are commercially deployed. 4G means a lot of different things for the companies involved, but for consumers, it's basically about data speed; how fast can you load full web sites on your phone or watch Hulu on your laptop? We wanted to see how these fancy new networks stack up where it counts. What we found may surprise you.
Is Sprint's 4G network "up to ten times faster" than 3G, as Sprint claims? Eh... based on our tests, we'd say that's misleading. But Sprint's 4G network does work, and it is fast.
Does T-Mobile's HSPA+ network offer "4G speeds". Yes, absolutely. In fact, despite being an upgrade to existing "3G" technology, we found that T-Mobile's HSPA+ network was often slightly faster than Sprint's "4G" network. By some measures, it's much faster.
That's the problem with the term "4G". There's some confusion about what it means.
To the engineers that create these technologies and decide the standards - like the fine folks at the ITU (International Telecommunication Union) - a technology is only "4G" if it meets a list of criteria. The ITU says "4G" should offer speeds of at least 100 Mbps. No current technology comes close to meeting that requirement, so according to the ITU, what Sprint's offering - and even the LTE technology Verizon is working on - are not true 4G.
But try telling that to Sprint and Verizon, whose marketing departments have clearly decided that their big new networks are "4G". It's not purely marketing spin, though; there is some sense to it. Sprint and Verizon are building these 4G networks from scratch, not upgrading their 3G networks. That's because Sprint's WiMAX - and Verizon's LTE - are all-new technologies that have very little in common with 3G. These new technologies are more modern and more data-centric. Because it's a whole new generation of technology, more advanced than the existing 3G (3rd-generation) technology, it makes sense to call it 4th generation, or 4G.
T-Mobile's story is different. They're taking the existing WCDMA/HSDPA 3G network and upgrading it to HSPA+ technology. It's still technically considered 3G technology by most, but on the most important spec - data speed - it's just as fast as the other networks' 4G, making it very much a viable competitor, regardless of what "G" it is.
In this article, we didn't set out to compare all carriers' data networks head-to-head. Rather, we're focusing only on the new technologies being offered by the two carriers advertising 4G or 4G-like speed. For a comprehensive look at all carriers' 3G networks, PC Magazine just published a good comparison.
AT&T, T-Mobile Offer Best 3G Performance
The 3G networks operated by AT&T and T-Mobile handily beat those operated by Sprint and Verizon Wireless in PCMag's Fastest Mobile Networks in 2014. AT&T and T-Mobile use HSPA/HSPA for 3G and Sprint and Verizon use CDMA EVDO Rev.
Oppo Shows Off R7 Plus and R5s Smartphones
Oppo today announced two new handsets, the R7 Plus and the R5s (pictured). Both share thin and premium designs with internal specs such as 1.5GHz octa-core Qualcomm Snapdragon 615 processors, 3GB of RAM, 32GB of storage, and 13-megapixel Sony cameras.
- R7 Plus: The larger of the two phones has a 6-inch, full HD AMOLED screen protected by Gorilla Glass 3, a 4,100mAh battery, and an 8-megapixel user-facing camera.
Sprint Can Commence WiMax Shutdown
A Massachusetts court has given Sprint permission to turn off its WiMax network in stages over the next two months. Sprint will turn WiMax off in 16 cities, including New York, today, with 39 more to follow on February 29, and the remaining 25 cities on March 31.
Sprint to Kill Off WiMax Once and for All On Nov. 6, 2015
Sprint today confirmed it will permanently shutter its WiMax network on or around November 6, 2015. The company had previously said it would operate the failed 4G network until "the end of 2015." Sprint said it has identified 6,000 "redundant sites that we expect to decommission and terminate the underlying leases," as part of the process, which will save the company some money.
HTC One A9: First Phone To Work on Verizon Without CDMA
HTC will sell an unlocked version of its new One A9 that can be used on Verizon's LTE network, even though the phone lacks the legacy CDMA technology found in all other Verizon phones to date. That makes the One A9 the first phone announced for use with Verizon in LTE-only mode.
table of data:
Also of note:
Sprint's 3G Network is about 1/3rd of the speed of AT&T's. My average on Sprint is 700kbps, my average on AT&T is 2058 kbps. Very rarely do I even break 900kbps on Sprint.
Sprint's WiMax Network isn't significantly faster than T-Mobile and AT&T's 3G Network. - Right now with decent signal from AT&T on the slower 3.2mbps network I beat 4 of the WiMax scores on Sprint's network.
WiMax coverage isn't nearly as solid as HSDPA - Just because an area is "covered" doesn't mean you get a usable signal...
Very insightful Rich
lol--WiMax! WiMax! WiMax...
Gotta love a nice plate of crow.
The big 4
But I think it fail to note whats the possibilities of 4G...
If I'm not mistaken 4G is cheaper to build upon to make faster, so for every X amount of money you put in to infrastructure with 4G, you will get X amount increase in speed. The 4G is cheaper to build upon to make faster then 3G or something like that.
But also how come Phone Scoop didn't have AT&T on there?
3G started out with technology like WCDMA that only achieved 384 kbps, then it evolved through various upgrades ...
real world experience in NYC with T-Mobile
3.75G: up to 9Mbps
latency is around 100-150ms (3.75 is lower).
Are you using a rocketstick or a phone to test this?
