| The LPR2430 Series 2.4 GHz transceiver modules provide a low cost, low-power solution for peer-to-peer, point-to-point and point-to-multipoint wireless designs. LPR2430 Series modules provide the flexibility and versatility to serve applications ranging from cable replacements to sensor networks. Based on the IEEE 802.15.4 wireless standard, the LPR2430 Series module is easy to integrate and provides robust wireless communications in applications where full mesh network operation is not required. The LPR2430 Series includes CNL V2.0 Network Layer firmware which features a flexible and simple-to-use Application Programming Interface.
VERSITILITY. Comprised of the low-power 1mW RF power LPR2430 / LPR2430A and the extended range 100mW RF power LPR2430ER / LPR2430ERA, the RFM LPR2430 Series modules provide the flexibility and versatility to serve a variety of applications, from simple cable replacement to remote terminal data collection to sophisticated sensor networks. The LPR2430 includes CNL V2.0 Network Layer firmware which features a flexible and simple-to-use Application Programming Interface.
SLEEP CAPABILITY. LPR2430 series modules provide years of battery operation supported through two sleep modes. Timer sleep allows the module to be configured to wake as often as every 100 milliseconds or as infrequently as once every 3.5 years. Interrupt sleep lets the module sleep until it is awoken by either an edge triggered interrupt or an ADC value exceeding configurable limits. Regardless of what wakes the module, the designer can configure the module to remain awake for up to 2 seconds after sending its data to provide an opportunity for an application to communicate to the module before it returns to sleep.
I/O AND AUTO REPORT CAPABILITY. LPR2430 series modules feature Analog, Digital and Serial I/O including Analog & Digital I/O binding.
Standard UART interface for serial communications plus 6 GPIO, 3 ADCs, and 2 DACs (PWMs)
With the I/O Binding feature, one node has the ability to output on 2 GPIO lines the input value of 2 GPIO lines from another node
Auto-reporting features allow many sensor nodes to be built without a dedicated microcontroller - the micro-controller on the module does all the work
Auto-reporting mode provides module I/O updates based on timer or interrupts - without the need for the application to poll or otherwise request data
Interrupts are generated by edge-triggered events or by exceeding user-defined limits on ADC values - and any interrupt can be used to wake a sleeping mode and have the module send its I/O data
OVERCOMES OBSTRUCTIONS / MULTIPATH FADES. LPR2430 modules feature a one-hop relay that enables one node to send data to a base radio through another node. This unique feature alleviates problems caused when a network works w |

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.

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. |
