Have Samsung missed the boat like Apple did with limited LTE support for the UK with their iPhone 5? Huawei Ascend P2 has LTE Advanced giving speeds up to 150Mb with a price tag of 350. EE will be doing tests on LTE Advanced this year.

Surely a flagship product with premium price tag should have it all not to be undercut by a bargain basement manufacturer.

Tests yes, but there's not likely to be any implementation of LTE advanced in the minimum contract term of any phone bought in the next few months. Today's LTE can in theory do up to 100Mbps I think, so are you really going to see a difference?

Reliable speeds of 20Mbps+ are all I'm worried about for the next few years, yes in a few years time we'll get faster, but I'm ok with standard LTE for now.

Because it is likely the chips that are able to do thie were not available in great enough numbers and the early gen chips are also likely to be battery draining beasts. A more efficient design by Qualcomm was released in the last couple of months so.... likely to be in new designs.

Samsung & Apple generally only use efficient designs than just trying to be first. S3 didn't have LTE for example but there were early gen chips out at the time.

LTE-A wont be out until at least this time next year..

The Galaxy S2 and S3 both had LTE varients. The LTE S2 was never released in the UK and the LTE S3 only got released in the UK when EE started using it.

I think Samsung may release an LTE Avanced version of the S4 at some point.

Yes.. but as i said the S3 never had it included until later when the better chips were available in Summer, it was released in September.

The I9210 a is battery hog on LTE.. few hours and it's dead. In many cases it uses so much battery on LTE it can actually get quite hot to hold.... People would not accept that from Samsung if they had used early gen chips in the S3.. and same goes for S4.

If one already has LTE phone I do not see LTE A as a big attraction at the moment. Given the release cycles they may as well wait and release it in Galaxy S5, together with 4K display and 64-core processor 4K is definitely something that could benefit from high transfer rates and with HDMI out it could be quite fun.

Anyway, how does LTE A perform if there are several phones connected on the same mast hogging multiple channels? There must be a point when speeds degenerate, how quickly does this happen?

Clearly Samsung felt happy enough to release an LTE version of the S2 even with some battery issues. Given Samsung are happy to do second issues of their product range then a few months down the line then an LTE Advanced version could be on the horizon.

The Huawei is not LTE Advanced (there aren't any LTE-A phones yet). It's still "old" LTE Release 8 but it is Category 4 which is faster than what we have had up until now and is what you'll need to make full use in June of the faster speeds EE announced yesterday.

The real question is what difference will LTE A make to the vast majority using a mobile phone to browse the Internet or stream YouTube etc? Nothing really... LTE A will be useful for the networks as a technology to increase capacity and offer more data to the expanding market for it but it will take a while for that capacity to be needed as 4G LTE on most networks will be a premium service and uptake will take time.

The LTE A issue will become relevant in about 2 years when networks actually have some customers using LTE once it has been rolled out.

Chances are that 3G technology improvements like DC-HSPDA will satisfy the vast majority of mobile customers for some time to come.

You should read this then from Qualcomm:

LTE Advanced can aggregate up to 5 carriers (up to 100 MHz) to increase user data rates and capacity for bursty applications such as web browsing. Aggregation (multicarrier) when combined with higher order MIMO can provide extremely high peak data rates, theoretically up to 1Gbps. Initially, aggregation of two 10 MHz carriers will enable peak data rates up to 150 Mbps (Cat 4).
http://www.qualcomm.com/solutions/wi...s/lte-advanced

Then read this about naming conventions too. There is no LTE-A:

The first of these is now appearing in networks and being branded "LTE-A", which has prompted some people to start calling the next revision "LTE-B" - a practice the 3GPP wishes to kill off before it takes root.


LTE stands for Long Term Evolution, and its first technicial specifications were outlined in 3GPP Release 8. LTE Advanced is a catch-all term for enhancements to the standard, right up to the still-being-drafted Release 12. There is no officially recognised LTE-B standard, although some companies have begun using the term in their marketing blurbs.

Well there's definitely plenty of potential for confusion when it comes to 4G / LTE names but I didn't think I was adding to it by using LTE-A which is a common abbreviation for LTE Advanced. Just to be clear though, by LTE-A I meant only LTE Advanced and not some sequence that runs A,B,C,D...

I think the bit you are getting wrong with the Qualcomm article is equating a certain speed with either LTE or LTE Advanced. However original Release 8 LTE can go up to around 300Mbps with enough MIMO streams. LTE Advanced also includes all the original LTE categories and adds some new ones. The key difference though is that LTE Advanced contains at least one enhancement from Release 10. An often mentioned one is carrier aggregation as in the Qualcomm link you posted and if you can do this it is classed as LTE Advanced. However if this is the only change you make then the speed of of two 10MHz carriers aggregated as per Release 10 isn't going to be any better than one 20 MHz wide carrier in Release 8. In the example you've linked to they both give Cat 4 speeds.

Hopefully that's a bit clearer.
