A study claims that HSPA is not to be displaced by LTE in the next five years
His thesis is build around the fact that HSPA as a technology may be sufficient for "many operators' needs for the next five years." Furthermore, carriers around the world may decide that it's a better near term solution simply to evolve their existing HSPA networks (into HSPA+, for example) rather than build an LTE network - and that will continue "as long as it makes good economic sense."
Another problem for 3GPP Long Term Evolution (as is the full name of LTE) may be the spectrum shortages. Grivolas' words on the matter:
"Ultimately, the availability of spectrum is certainly an issue that will have a strong bearing on the commercial success of LTE, as its availability is fundamental to service launches. With that in mind, it may pay for operators to hang back and let others invest in the development of the ecosystem and make mistakes first. "
That's an interesting opinion. It's obvious that HSPA and LTE are able to complement one another and LTE's introduction doesn't necessary bring the end of HSPA. However, a lot of people (and some carriers) believe that LTE is the future. Tell us, how you envisage the network evolution in the next five years?

well im contented with with HSPA.. even with HSDPA... its already fast... its just a matter of 3 seconds which makes HSPA dominant over HSDPA... but whatever it is... LTE or HSPA... both of them delivers very high data rates which the phone cant handle or make use all of it.

since Tmobile has already commited to 42mb/s HSPA+ in 2011, id say theres some good life left in it. When we get to the point that we can actually TELL the difference between a42mb connection and say an 80+ with everyday use, then i can see HSPA+ dying out. for web page loads and 99.999% of application downloads, u will not notice the difference.

I think companies like AT&T and tmo should forgoe LTE rollouts and continue to advance their hspa+ networks. Yeah I know everyone is hungry for 4G but if everyone is calling these 3.75G networks 4G who cares. Let verizon have LTE. They've already started so no sense in stopping. Plus it's backward compatible with UMTS and HSPA networks anyway. And in the meantime the 3 carriers should massively research LTE advanced in hopes of bringing that to market asap. After all HSPA+ and LTE are capable of blazing speeds in the mean time.

But Verizon LTE is ready NOW anyway. It has more potential to expand its speeds, so y wouldnt they continue on with it? just saves them the time in upgrading the towers in 5 years. id have to assume that upgrading the lte speed as time goes on would b less costly than going to hspa+ then LTE. just seems like thanks to verizons resources they are set up well to be as good as hspa+ and get better than it quicker than other carriers.

Lets morph into reality, over 130 carriers world wide have committed to LTE. It will become the global standard. It is fiber based broadband based technology that is simply better than any competition it may face.
Pound for Pound any comparisions will render Verizon Wireless' LTE network as the superior 4th generation data network on the planet.

I think you are the one who needs a reality check.
130 countries are "committed" to use LTE?
First off, lets wait and see who actually ends up using LTE.
Secondly, to date, 145 countries are using WiMax. Some not to its fullest capacity, but the point is, we have more countries actually using WiMax right NOW, than countries who are "planning" to use LTE.
The numbers speak for themselves.
I am sure LTE will end up being used in a lot of countries, but at least wait to see who actually backs their talk up with action!

the only reason there is a so called shortage of the 700mhz (lte) spectrum is due to the fact that verizon purchased it years ago and there is a shortage now only because its licensed to vzw. its a bunch of crap that all these other companies are even getting away with advertising they have a 4g network... that is a complete lie and marketing scam to get all the people to buy there phones that know nothing about the networks. LTE is the future and it will be obvious when you use a vzw 4g phone with 2-4 times greater speeds than these fake 4g networks. not to mention 700mhz can penetrate concrete walls and metal buildings much better than the other crap.

LTE isnt even "technically" 4G either. Everyone is apart of the "marketing scam".

The ITU classifies WiMax and LTE as 4G.
