This document describes the Remote Radio Unit multiStandard (RRUS). Remote Radio Unit (RRU) is often used as a generic expression for all remotely installed radio units. It is also the name of models prior to the RRUS versions described in this document.
The RRUS remotely extends the reach of the RBS by up to 40 km. The RRUS is designed to be located near the antenna. A fiber optic cable connects the RRUS to the RBS main unit or an expanded macro RBS. Up to six RRUSs can be connected in a star configuration or in a cascade configuration with optical cable links.
