“Single RAN’ MSR (Multi-Standard Radio) base stations are capable of managing LTE/HSPA/GSM functionality in a single base station unit, and hence reduces the operators’ total cost of ownership (TCO). This course addresses SRAN architecture; functionality and shared IP back haul connectivity issues.
EXPECTED ACCOMPLISHMENTS
- Highlight the main features of an MSR base station
- Describe applicability of software defined radios to SRAN
- Identify potential RF issues associated with MSR operation
- Outline functionality of carrier Ethernet and MPLS in the context of SRAN backhaul transport
- Highlight the functions performed by the SeGW
- Describe the core network connectivity required to support SRAN
- Describe IP flow mobility in SRAN environment
- Describe the role of RFSP index in managing reselection and handover within a SRAN
- Step through the stages of a Single RAN deployment process
- Engineers and Technicians involved in Mobile Network operation and maintenance, planning and optimization.
TARGET AUDIENCE
Managers, Engineers, and Technicians involved in the planning, deployment and maintenance of mobile networks
