He says consumers generally won't notice the difference in speed between AT&T's HSPA-plus and upcoming LTE networks, so it makes sense to call both 4G ...the carrier will speed up the LTE network build out in 2012 and 2013.
basically, they got the ceo of ATT wireless to say on-record that there would be no speed improvements on their network for a very long time... They probably won't have good (geographic) coverage on the new network for at least 2-3 years...
Can anyone comment on why they are just starting to build a network with tech that isn't higher speed than their current network? I'm sure that's a lot of money spent, and you'd think that if they went to the trouble they'd deploy something that was faster.
- fuzzmeister 16y agoFrom what I've read, LTE will certainly be faster than HSPA+. I think what he is saying is that HSPA+ is "fast enough" for most smartphone activities (such as web browsing), so the speed boost provided by LTE will only be noticed in more data-intensive applications, such as video streaming.
- Prisen 16y agoThe fastest implementations of HSPA-plus are actually coming close to the theoretical limits of how much data can be transferred on a given frequency band, but they have some big drawbacks compared to LTE. The one that will be most noticeable at first is latency, which is at most half that of HSPA (the requirement is 20ms for LTE). The second is that LTE will be able to use bigger frequency bands than HSPA, eventually reaching a 100 MHz band. Even ignoring that, AT&T's current HSPA-plus network is nowhere near as fast as HSPA-plus can be. They would need to upgrade it to get close to the raw speed of LTE.
