White papers RF Power Options in ZigBee™ Solutions While ZigBee is a "low power" standard, "high power" product versions are much needed — and are very much ZigBee standard. This paper explains how the the availability of ZigBee radios with high and low RF power options is key to ZigBee's appeal in industrial settings, allowing design engineers to tie radio selection directly to an application’s requirements for range and resistance to multipath fading. ZigBee Wireless Transceiver Engineering OptionsZigBee's mesh networking capability, which compensates for obstructions and reduces range requirements, is especially prized in industrial applications. But with a technology this new, how can the RF designer best realize a successful ZigBee implementation? This white paper provides a brief, realistic assessment of ZigBee's value in industrial environments, examines the types of components available today at the chip and module level, and discusses the practical considerations to be weighed in deciding to pursue ZigBee mesh networking in a specific application. Wireless Communications for Industrial Applications This paper examines the unique requirements and challenges of wireless communications in an industrial setting and provides an overview of RFM wireless products designed specifically for these applications. The information presented serves as a guide for systems integrators and end users responsible for factory floor automation, industrial/PLC control, SCADA, telemetry and related data communications applications.

IEEE 802.11 and Industrial / Factory Floor Applications Used within the office LAN environments for which it is designed, the IEEE 802.11 wireless standard can contribute to product interoperability and convenience. However, if applied outside their intended domain (for example, in an industrial communications application), 802.11-based devices typically exhibit poor performance and increase communication support costs. This paper evaluates the suitability of the IEEE 802.11 standard for wireless factory and industrial applications. (~ 25 KB, Adobe PDF format) Wireless Transceivers—Make or Buy? In choosing to add wireless data capability to a new or existing product, every designer faces a critical decision: whether to engineer the functionality in-house or buy a ready-made module for the application. This paper provides a cost analysis to explore the relative merits of each approach. (~ 160 KB, Adobe PDF format) WaveBolt System DescriptionThe WaveBolt™ system is a fixed wireless point-to-multipoint Internet access system designed specifically for residential and small business customers in areas where DSL and cable modem access are unavailable, unaffordable or otherwise undesirable. The WaveBolt system provides data speeds comparable to ADSL. Simple to install, the WaveBolt CPE in many cases will be installed by the end user. And, where customers choose to have the CPE installed, a single, short site visit is all that is required to complete the installation. (~ 162 KB, Adobe PDF format.) Lightning and Surge ProtectionBecause wireless systems are typically located out of doors and have components located on towers and tall buildings, they are especially susceptible to damage from lightning. This paper explores the proper design and implementation of a communications surge protection system to reduce down time and lower liability for people and property. (~ 152 KB, Adobe PDF format.)
