DOCSIS® FOR LTE SMALL CELL BACKHAUL
- Glapa M.
HFC/DOCSIS access networks are widely used to address the needs of residential and enterprise consumers for High Speed Internet (HSI), video, and voice services. The hot question these days is whether the HFC/DOCSIS networks can support the backhaul needs of LTE small cells? As the characteristics of the cable networks can vary significantly across markets, it is not possible to have a clear yes/no answer, and requires further analysis of network configuration. In addition, there are Proof of Concepts being planned to test the viability of LTE small cell services, but no results are publically available. Since the primary concern here is about meeting throughput and performance (packet delay/jitter/loss) requirements, there is not a clear yes or a no answer as many factors play a significant role in determining the feasibility of any given network. The objective of this paper is to identify the factors that influence the viability of HFC/DOCSIS for LTE small cells backhaul, along with key performance requirements. It is recommended that a custom analysis is done with the target MSO to understand the extent to which the HFC/DOCSIS network can be used for their MNO partner.
