2.0 Introduction
In a split Radio Base Station (RBS) architecture the typical RBS consists of a Base Band Unit
(BBU) and Remote Radio Heads (RRH) connected by cabling. Power to the RRH is provided
through copper cables traveling from the base station to the top of the tower or roof top. This
creates a conductive path, making the active equipment at the top and the base of the site
vulnerable to damage by direct lightning strikes. Protection systems installed in front of both
the BBU and the RRH must be able to withstand direct lightning currents in order to protect
the sensitive equipment. Raycap’s RRH solutions featuring Strikesorb® SPD technology
management solutions.
