Not to be outdone by Qualcomm’s SoC group, Qualcomm’s communication groups are busy at MWC 2015 as well. Though Qualcomm Technologies and Qualcomm Atheros are not announcing any major new products at this moment, the two of them are on the show floor to demonstrate the status of their various LTE initiatives that we should see in upcoming and future products, in conjunction with infrastructure partner Ericsson.

First and foremost, Qualcomm and Ericsson will be offering the first public demonstration of LTE category 11 hardware in action. LTE category 11 increases the download rate of LTE to 600Mbps through a combination of tri-band (3x20MHz) carrier aggregation and the use of QAM256 encoding, with the latter being the major addition of category 11. Due to the use of QAM256 and the higher SNR required to use it – not to mention 60MHz of spectrum – category 11 is being targeted at small scale deployments where cleaner signals and more spectrum is readily available, such as indoor deployments and carefully constructed outdoor environments.
