Enea Freescale webinar 12 Sep 2012. The availability and performance of LTE components are becoming a critical issue as carriers move ahead with LTE deployments. Highly integrated devices using the latest silicon technology are transforming this market. At this critical time we take a look at the latest solutions involving LTE for cellular base stations as well as the emerging HetNet (heterogeneous networks) technology to provide the fully integrated coverage and bandwidth that are needed in next-generation mobile infrastructure equipment.

21. LTE/HSPA Implementation Strategy
 Layer 2-3
 Can be implemented in a
communication processor
 Layer 2 is often implemented
together with L1 in the DSP to
reduce the latency of the MAC
scheduler and L1 interaction
 L1 or Physical Layer (PHY)
 Usually implemented in a DSP
 The DSP+MPU integration
allow L2 to move to the MPU Source: Enea
