TB w/4G vs Iphone 4S w/dual 3G

Touche MOFO! XD

Pinning an arbitrary label like 4G on mobile radio technology is a lot like what pinning generation labels on cars would be. It's a single number trying to loosely represent a number of requirements that were more or less chosen arbitrarily. You could call model T fords 1G and work your way up to 10G veyrons, and it's pretty obvious that 10G is better in that case, but what about a 9G corvette? Veyrons might be faster but the corvette has better fuel economy, is less expensive, still pretty fast and has better battery life.

4G was a whole collection of requirements, most of which got completely lost once the definition got into the hands of consumers. Then it turned into 1 Gbps stationary, 100 Mbps mobile. Thats all anyone remembers. That is NOT 4G. That was only one of the proposed requirements and it's the most consumer facing one. 4G also has to be sold to the phone companies and for them spectral efficiency is much more important than how much bandwidth can be delivered to any one single customer at a time. It's what the overall sector throughput is, how many users you can service at a time given the ultimate in scarse resources - spectrum. From that point of view, HSPA+ looks pretty good.

Companies are looking at dual carrier HSPA not because it will give a single handset the potential to reach 84 Mbps, but because studies show that overall sector throughput is better with a single channel with two bonded carriers rather than two stacked single carrier sectors.
 
Maybe not for the original definition but the ITU appeased the carriers by modifying it shortly after to include LTE/Wimax and "evolved" 3G technologies like HSPA+.
Right. That was the "ITU Marketing" department. :D

Actually lte is true 4g. It has already been stated ill find the link and post it later

The point that PJnc was making (and others) is that there is no "True 4G" except what the ITU defined as "true". What is "True" but with wildly varying specifications, are technologies such as "LTE/Wimax and "evolved" 3G technologies like HSPA+". When you use the technology terms, rather than the "marketing" terms (i.e. 4G) then you get the "True" picture.

The problem with the marketing term 4G is that each carrier has progressed through different technologies at different rates. Hence, each carrier can "true"thfully say that they are on their fourth generation technology. But you cannot compare the fourth generation of one carrier to the forth generation of another carrier. Apples and oranges.

Here is the ITU announcement certifying (only) LTE-Advanced and WiMax 2 as 4G:
Newsroom • Press Release

"Geneva, 21 October 2010 ? ITU?s Radiocommunication Sector (ITU-R) has completed the assessment of six candidate submissions for the global 4G mobile wireless broadband technology, otherwise known as IMT-Advanced. Harmonization among these proposals has resulted in two technologies, ?LTE-Advanced1? and ?WirelessMAN-Advanced2? being accorded the official designation of IMT-Advanced, qualifying them as true 4G technologies."

Note that LTE as currently deployed is NOT the same thing as LTE-Advanced.

That above definition developed from formal requirements for target end user bitrates, sector throughput, spectral efficiency and certain technology use.

Later on, after a number of US Carriers started calling a wide variety of formerly not-4G technologies "4G", the ITU loosened the definition of 4G to include almost everything:

Newsroom • Press Release

Following a detailed evaluation against stringent technical and operational criteria, ITU has determined that ?LTE-Advanced? and ?WirelessMAN-Advanced? should be accorded the official designation of IMT-Advanced. As the most advanced technologies currently defined for global wireless mobile broadband communications, IMT-Advanced is considered as ?4G?, although it is recognized that this term, while undefined, may also be applied to the forerunners of these technologies, LTE and WiMax, and to other evolved 3G technologies providing a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed. The detailed specifications of the IMT-Advanced technologies will be provided in a new ITU-R Recommendation expected in early 2012.

HSPA+, WiMax (original), and LTE (original), EVDO Rev B, and pretty much everything faster than IMT-2000 can call itself 4G now. Not based on any technical specification, but simply because it's faster than 3G.

So, going back to the original argument, either both the Thunderbolt and iPhone 4S (on AT&T) are 4G (based on the new non-technical definition) or neither are (based on the original definition). Take your pick.
