LTE meets the need in 3GPP

Edinburgh, September 16, 2014

3GPP has used a 4G (LTE) cellular connection during the 65th Plenary meetings in Edinburgh, from the 9th – 17th September, using the project’s own technology as the primary source of connectivity for the first time in a major meeting.

Interoperable Small Cells

ETSI has finalised a Report on the 2nd Small Cell LTE Plugfest, organised in partnership with the Small Cell Forum and held at the Orange Labs in Paris.

During ten days of testing 65 experts from a variety of organizations (26 in total) cooperated on debugging vendor solutions and used lab time to tackle potential ambiguities in the standards, which will help feedback fixes to the interface specifications (See the event Report, for “feedback on base specifications”).

Test sessions concentrated on S1, X2 and management interfaces, covering areas such as Security, Management, Voice Support via CS Fall-back Schemes, Voice and Video over LTE, Commercial Mobile Alert Systems and Self Organising Networks. One of the key areas of focus was the testing of multi-vendor mobility and SON in heterogeneous networks.

3GPP supports High Efficiency Video Coding

3GPP Release 12 specifications now include support for the HEVC (High Efficiency Video Coding) video codec – H.265, providing a technical solution for highly efficient delivery of download, streaming and conversational video services.

Addressing the challenge of ever growing video traffic over mobile networks, HEVC provides a remedy for operators to increase quality of experience while at the same time reducing bandwidth consumption of video services, typically by a factor of 2 compared to the best technologies available prior to Release-12.

3GPP SA4 - the Codec working group - completed their study of the compression efficiency of HEVC in the context of 3GPP services by conducting objective and subjective tests, producing the 26.906 technical report to document the findings. Accordingly, the HEVC video codec is specified with decoding capabilities conforming to the Main profile, Main tier, up to level 3.1 thus allowing HD video services in 720p up to 25 or 30 frames per second.

LTE-Advanced  is bringing more than just carrier aggregation in 3GPP Release 12

Carrier aggregation multiplies maximum user speeds several-fold and significantly improves capacity utilization by increasing trunking efficiency as more spectrum blocks are added; but LTE-Advanced can deliver so much more including heterogeneous network capabilities in particular.

Coordinating the low-power layer of small cells with the macro network improves performance across the entire network while also further boosting efficiencies in spectrum use and power consumption, automating network configuration and optimization. The upcoming 3GPP Release 12 (due to be frozen September 2014) standardises various capabilities in these developments including dual connectivity, small cell on/off and 256 QAM.
