LTE to 5G Evolution: Key Device Upgrade Considerations for Increasing Efficiencies in the Network


The network evolution to LTE-Advanced (LTE-A) and LTE-Advanced Pro (LTE-A Pro) are essential enhancements for extending the lifespan of LTE, and critical steps for ensuring a smooth transition to 5G. Not only will these technologies enable operators to launch new high-bandwidth services and unlock new business opportunities, but these upgrades will also dramatically improve network performance in terms of coverage, cell-edge capacity, and spectral efficiency.

Smartphones populating these networks will have a determinant role in augmenting the efficiency of these networks. In order to maximize their effectiveness, it is essential that they are packed with vital RF front-end (RFFE) technologies, such as RFFE architectures supporting 4x4 MIMO, envelope tracking (ET), and antenna tuning, while ensuring that all are integrated appropriately into well-constructed modem-to-antenna designs.
