Deploying
Industrial Wireless Solutions - Wireless technology has not been widely
adopted for in-plant applications. Concerns about reliability, security, and
battery life of wireless devices have slowed adoption of wireless options even
where traditional wired solutions were cost-prohibitive or operationally
difficult. That's changing as improvements in wireless technology address these
concerns.
Self-Organizing
Networks: Wireless Topologies for In-Plant Applications
-The topography of a wireless network is simply the way network components
are arranged. It describes the physical layout of devices, routers,
and gateways, as well as the data flow paths between them. Three
of the most common wireless topologies for in-plant applications are star,
mesh, and cluster-tree. By understanding the strengths and weaknesses
of each, you can determine which topology is best for your specific
application.

In
2008, Wireless a No-Brainer - David Savells and Brent McAdams
- Advantages of wireless I/O go far beyond the cost of wiring: Economies of
scale, fail safe, flexibility, reliability, diagnostics and low power consumption
- Historically, regardless of the industry, hardwiring has been the only option
available for users to connect remote instrumentation assets in the
field.However, new technology enabling greater use of spread spectrum radios
gives companies the ability to connect remote instrumentation in the field
without the need for a costly, wired infrastructure - Thanks to ISA/InTech.
Users
