North American railroad signals generally fall into the category of multi-headed electrically lit units displaying speed-based or weak route signaling.orth American signals generally follow a common layout. A high signal consists of one to three heads mounted roughly in a vertical stack, each head capable of displaying one to four different aspects. Automatic signals are identified with a number plate whereas absolute signals are not.
One of the major players is the deployment of Remote Radio Units (RRU) also called Remote Radio Heads (RRH). A Remote Radio Unit is a single unit in which only the RF front-end functionalities are implemented. It is connected to the remaining baseband processing part (Base Band Unit- BBU) through a bidirectional link. It greatly reduces the carriersâ requirement for site resources and their investment and meanwhile improves the effect of coverage.
