I’ll take what’s behind 3GPP Release 9, no make that Release 10
Signals Research Group, LLC, Sep 2010
Now that 3GPP Release 9 is officially in the books the publisher thought it was an appropriate time to take a look at what the future holds for the wireless industry with a particular focus on Release 9 and Release 10 of the 3GPP standard.
LTE-Advanced. While LTE has erroneously earned the '4G' title, it is not until LTE-Advanced (Release 10) that it stands the chance of earning the ITU-Advanced moniker. Interestingly, some of the LTE (Release 8) performance characteristics actually meet the ITU-Advanced requirements while some of the LTE-Advanced characteristics greatly exceed them. The publisher explains each of the key features and identify what we like and what we don't like (see next bullets)
What we like. For reasons that the publisher discusses, LTE-Advanced features, such as carrier aggregation, multi-user MIMO (Mu-MIMO), Coordinated Multipoint Transmission and Reception (CoMP), and SON/heterogeneous networks make sense and they should achieve market adoption and have a material impact on the user experience and/or the overall performance of the network.
What we don't like. Other features, such as higher orders of MIMO in the downlink and uplink make little sense and they will serve little purpose other than bragging rights that sound great on paper but have no real-world practicalities.
In the other corner. Release 9 and Release 10 introduce compelling features for HSPA (e.g., HSPA+) and new network architecture features, such as SIPTO and LIPA, and services that are nearly as compelling as LTE-Advanced, yet they receive very little attention. In particular, some of the HSPA+ features can have a material impact on the end user data rate and/or overall network capacity in certain situations. Further, a close review of the releases helps shed some light into the future HSPA and LTE plans of certain operators in North America and Asia.
Good old GSM. Release 9 and Release 10 also introduce compelling features and services for legacy GSM which can meaningfully increase voice capacity (e.g., VAMOS) or support new services (e.g., CRS). The publisher discusses.
