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.
Mobility is another key factor. In a traditional cable-linked installation, moving a transmitter even a few tens of metres can involve considerable cost and can interrupt production. 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.
