3GPP Release 11 contains an interesting work item, the bundling of up to 8 x 5 MHz HSDPA channels in two different bands. Octa-carrier HSDPA with a top downlink data rate with 64QAM modulation and MIMO of 337.5 MBit/s (HSDPA category 36). Sure, the data rate is impressive but I have to wonder if it will be praticable in the real world: I can't think of any network operator who would have 8 channels available. And even if there were some, why would you want to bundle that much spectrum for HSPA when the general trend is to move to LTE anyway? Am I missing something here?
