Chapter 13: Wireless



 The lure of wireless is irresistible – with the elimination of cabling, marshalling points, control room cabinets, cabling systems and all associated labour costs for installing and maintaining these systems. This represents a substantial saving.

This problem is not encountered with wireless since it can be moved and installed much faster than a cable-based system.

A wireless network infrastructure enables completely new solutions in areas where cables cannot be used, or can only be used with limitations – due to mechanical restrictions, security requirements, or other environmental considerations.

However, before opting for wireless, many issues have to be considered – especially the question of standards.
