Each WIT OEM Module Developer’s Kits contain two selfcontained wireless modems built around specific OEM modules. Additionally, two OEM modules are included in the kit. The self-contained units allow developers to get up and running quickly using standard RS-232 interfaces without having to build a 3.3V level serial interface. The self-contained modems include LEDs to provide modem status information visually, and a built-in rechargeable battery pack allows the developer to use the modems without being tethered to a power source. This provides a simple way to test the range of the radios. Other than the true RS-232 signals of the serial interface, the self-contained modems operate exactly as the OEM modules.

White Papers
    Lightning and Surge Protection
    Because 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.)
    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.
    WaveBolt System Description
    The 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.)
    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. (~ 136 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)
    ZigBee Wireless Transceiver Engineering Options
    ZigBee'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 ZigBees 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.
