xAbout this document

The document suite assumes that the reader possesses a basic knowledge of the cellular system and radio propagation and is familiar with measurement units incorporated in the system. Therefore, this document will not provide detailed information on the theory of switching and radio propagation.

How this publication is organized

This publication is organized to present the following information:

•an introduction to the DualMode Metrocell Cell Site

•the Metrocell cell site configurations; omni, 120° STSR and 60° STSR

•the equipment layouts, block diagrams and transmit and receive cabling for each configuration

•the cell site components required for each configuration

•the power and grounding requirements for a Metrocell cell site

•information on datafilling a Metrocell.

Applicability of this publication

This publication is generically applicable to MTX01 feature functionality, yet captures some BCS-independent environment and implementation issues.
