You didn't prove that LTE is a natural evolution of GSM. Don't confuse GSM with WCDMA and WCDMA with LTE either. Like the other poster said. LTE is IP-based (OFDM for the downlink). What part of GSM is IP-based? There will be no simple software upgrade from UMTS/HSDPA sites. They will require completely new hardware. There is NO guarantee that calls that originate on the old 2G GSM network or the newer WCDMA network will soft handoff to any LTE technology. With the stock market the way it is and the way AT&T moves as slow as molasses with their technology rollouts, I don't see them really rushing to roll LTE out either. I'm sure Vodafone and Verizon will market the technology much sooner. "Natural progression," in this case implies that the greater majority of GSM operators that are part of the "Association," mutually agreed that they'd unanimously migrate to a new standard. From a cost perspective, the move to LTE made much more sense since it required less bandwidth to operate with while allowing the various telcos to stay within budget. This was clearly a pure politics and money based decision.

You didn't prove that LTE is a natural evolution of GSM. You missed the point as well. GSM evolved to EDGE, which then evolved to UMTS. HSPA is an extension/evolution of UMTS. LTE is the next evolution of all the prior services, again, based on the core GSM design. For your reading pleasure: said by LTE Technical Description : 3GPP LTE (Long Term Evolution) is the name given to a project within the Third Generation Partnership Project to improve the UMTS mobile phone standard to cope with future requirements. Goals include improving efficiency, lowering costs, improving services, making use of new spectrum opportunities, and better integration with other open standards. The LTE project is not a standard, but it will result in the new evolved release 8 of the UMTS standard, including mostly or wholly extensions and modifications of the UMTS system said by Howard F : There will be no simple software upgrade from UMTS/HSDPA sites. They will require completely new hardware. There is NO guarantee that calls that originate on the old 2G GSM network or the newer WCDMA network will soft handoff to any LTE technology. Again, you missed the point. UMTS wasnt a simple software upgrade from GSM/EDGE either! NEW equipment has been required at each major "jump" in technology. The same applies with LTE. This is nothing new, and has happened multiple times already. Simply because equipment upgrades are required, in no way precludes something from being evolutionary. The full description, along with the evolutionary lineage (along the right hand side) can be found at the following link: »en.wikipedia.org/wiki/3GPP_Long_···volution Mobile communication standards GSM / UMTS (3GPP) Family -------------------------------------------------------------------------------- 2G GSM GPRS EDGE (EGPRS) EDGE Evolution HSCSD 3G UMTS (3GSM) HSPA HSDPA HSUPA HSPA+ UMTS-TDD TD-CDMA TD-SCDMA FOMA Pre-4G UMTS Revision 8 LTE HSOPA (Super 3G) -- с новым годом
