Re: Better for Promoting CDMA Abroad
said by Howard F :
All you quoted proves that UMTS is CDMA based (on the airlink - WCDMA) like the other guys said. 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:
