How is RRU connected to a base station?The RRU is connected to the base station via the fiber optic link which is bi-directional link. The optical interface link is also known as CPRI (Common Public Radio Interface). CPRI is a interface protocol developed by combination of major telecom equipment's manufacturing company.
How can a PSU reduce heat and interference in a RRU?Minimizing heat and interference Another design being considered is based on the integration of the PSU within the RRU to reduce the RRU’s size and weight. In this architecture, the PSU shares the heatsink with the PA.
What factors affect a tower-top RRU?Cables are another important factor. Today, multiple pairs of low-gauge cables are used to bring -48 V power to the tower-top RRU while minimizing voltage drops across them. In addition to being expensive, these cables also are heavy, which is problematic if an operator wants to lease space on sites that are already near weight capacity.
How much power does a PSU need?This is when the PSU is no longer powering the PA, which is the main power draw, but still needs to power other electronics. The current target for low-load efficiency is about 30 W. Some OEMs would like to see that drop to nearly 10
