In the second part of this year Qualcomm says that it will solve 4G LTE fragmentation at Mobile World Congress.Or they at least anounced it.
Well you might say “what’s the problem?”.Well when you go on holiday to another country and you hear that it has 4G so you bring your iPhone and you are really excited,then.Sorry,your 4G device doesn’t work.You’re going to have to use 3G.
Roberto Di Pietro,who is a VP at Qualcomm in Europe,said to CNET that the solution is their new RF360 product,which they plan to sell to smartphone makers.He was also pushing that Qualcom is the solution.
“LTE is the first technology to be capable of being present in all the different regions worldwide. The issue is that the spectrum is completely different in different regions. Band support is one of the major issues we are working on.”
“Currently there are around 40 different frequencies on which LTE is available. Our chipset supports around 40 different bandwidths. It is a step forward for the LTE global roaming scenario where you can roam with a single device in different regions.”
If he is true,you will be in theory be able to use a phone with 4G worldwide.Or you could get round the DCMA.By buying a phone in Europe and unlocking it there,then go the U.S.A and connect to your network of choice(If they CDMA/GSM tech in europe).However,it’s roaming.So there is lots of charges,really.A lot of charges.
He made some other comments about what 4G will be like at the end of the year.Like there will be cheaper and we’ll have data speeds of 150 MB/s.Maybe.
