Fronthaul using CPRI evolved from the need of mobile operators to reduce their carbon footprint, obtain gains by pooling processing resources, and deploy advanced network features like Carrier Aggregation (CA) and Coordinated Multipoint (CoMP). The disadvantage of this type of Fronthaul is that it needs ‘Ideal Transport’ (Defined by 3GPP as 2.5 µs latency and throughput up to 10 Gbps). Continue reading
In 2017, Northern California Power Agency (NCPA) was faced with the challenge of linking two microwave sites in mountainous terrain with no line of sight between them. They were looking for an effective, cost-efficient way to complete the microwave segment of their network in California’s Northern Central area. Continue reading
Virtualized RAN (vRAN) enables operators to run Base Band Unit (BBU) functions on off the shelf hardware as virtualized network functions (VNFs). This can provide operators with the ability to avoid proprietary vendor lock-in as generic core and base station hardware can replace proprietary hardware. Currently Centralized RAN (C-RAN) uses a fixed Fronthaul split that requires a high capacity and low latency proprietary optical CPRI interface. Continue reading
Q: Can Extra High Power (EHP) Radios Reduce Need for Space Diversity (SD) in Microwave Networks?
A: Yes.
