Propel mobile broadband even further Enhance user experience and deliver efficient solutions to increase capacity
Carrier Aggregation evolution—wider bandwidths Aggregating more carriers, diverse spectrum types and across different cells
LTE in unlicensed spectrum Make the best use of the vast amounts of unlicensed spectrum available
TDD/FDD evolution—faster, more flexible Enable significantly lower latency, adaptive UL/DL configuration, and more
Many more antennas—path to massive MIMO Exploit 3D beamforming (FD-MIMO) to increase capacity and coverage
Gbps+ peak rates
More uniform experience
Better coverage
Significantly lower latencies
