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.

6. LTE Is Significant Step Forward
• LTE provides 2 to 5 times greater spectral
efficiency than most advanced 3G networks
– Lower cost per bit
• Faster downloads
– Up to 100 Mbit/s initially
– Better user experience
• Reduced OPEX and CAPEX
– LTE base station cost <1/5 HSPA cost per user per
month (based on 10 Gbit/s per month)
– Energy efficient

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
