Sorry if re-post... I did use the search!
MaximumPC already did a article on this 2 months ago. Basically we're not technically getting 4G, more like 3.5G to be exact.
- Will the real 4g please stand up?
LTE can reach speeds of 100Mb/s downlink and 50Mb/s uplink, while WiMAX delivers up to 128Mb/s down and 56Mb/s up. These speeds hurtle past 3G standards, but they're still far off the 4G purists' target, which has led some to dub LTE and WiMAX "3.9G" technologies.
The ITU-R guideline for true 4G is known as IMT (International Mobile Telecommunications) Advanced. According to that standards body, wireless technologies must run at 1Gb/s for stationary users and 100Mb/s for moving connections. The IMT Advanced guideline also calls for significantly reduced latency: 10ms.
The ITU-R hasn't identified a specification that meets it s goals for IMT Advanced; instead, the next generations of LTE and WiMAXâ€”LTE Advanced and IEEE 802.16eâ€”are being designed to achieve those speeds.
While the ITU-R definition of 4G will push the industry toward even faster performance, carriers defend their "4G" designators. "We're talking about doing basically an order of magnitude change in the capabilities of our wireless technology," says Verizon's Higgins. "To us, that's a meaningful difference and is worthy of creating the right kind of brand around that, which is '4G'."
But this is the same as how the new USB3.0 is marketed to the public. All you see is 10x the speed of USB2.0, which is true, but there's so much more in between that a consumer needs before they can take advantage of Superspeed USB (source, cable, destination) all have to be up to spec or you will not see USB3 speeds.
