May I know what the capacity toa 3GPP/LTE cell is? Surely, I appreciate the information available on this website. I understand that the capacity to a 3G/UMTS cell is 3.84Mcps.

Peak download rates of 326.4 Mbit/s for 4×4 antennas, 172.8 Mbit/s for 2×2 antennas for every 20 MHz of spectrum.

Want to give a service with even more bandwidth than that? Easy, just give more spectrum in any of LTE’s 11 bands - in slices as small as 1.25MHz!

Nice.

LTE is definitely a 4G technology -- its very name demonstrates this: Long Term Evolution (of UMTS). The long term evolution of a 3G technology would be, by definition 4G. As for WiMAX, FDMA is currently unsupported. Yes, there is support in 802.16e, but so far no finalized profile from the WiMAX Forum. Without the profile, there is no non-proprietary equipment and thus no way to do a wide-scale commercial deployment. That said, there would be such a profile damn quick if Verizon or the like showed interest, so I do agree that if they wanted to Verizon could certainly deploy WiMAX.</p> K, I like WiMAX too, but you are just plain wrong.

WiMAX and LTE will be limited to the backhaul capacity of the nearest serving WiMAX or LTE cell site and the number of users utilizing the technology at one time… they will all be sharing the same backhaul pipe.

Shah, LTE could threaten fiber if it can reach the speeds it advertises, but it won’t be widely available for four more years or so.

Certainly, I can see how WiMax can be subsumed into LTE and those that get WiMax right will have an upper hand when transitioning over to LTE.

Does LTE threaten fiber roll-outs? How does it compete with the new breed of satellite Internet technologies Japan has recently experimented with?
