Industrial wireless spread-spectrum wireless radios use 2.4 GHz spectrum

FreeWave Technologies offers the GX product line operating in the globally available 2.4 GHz spectrum with the release of the GXM, GXCP, and GX-C Serial radio.


FreeWave Technologies GX product line, 2.4 GHz wireless industrial radiosFreeWave Technologies, manufacturer of spread spectrum and licensed radios for critical data transmission, offers the GX product line operating in the globally available 2.4 GHz spectrum with the release of the GXM, GXCP, and GX-C Serial radio.  The GX line of radios provides OEMs, integrators, and end-users who have adopted FreeWave’s popular 900 MHz FGR and FGR2 product families with a familiar option in 2.4 GHz with FCC, IC, ETSI, and UL Class 1 Division 2 compliance in one radio. The GXCP is ideal for cathodic protection applications and the  GXM offers the same tiny foot print as FreeWave’s 900 MHz MM2 radio (2-inches tall X 1.4-inches wide), suited for industrial and manufacturing applications, the company said. The GX-C radio is suited for use in a variety of markets, including oil and gas, water/wastewater, and industries with similar SCADA applications.

Proprietary spread spectrum technology prevents detection and unauthorized access; 128 bit or 256 bit AES
encryption is available.

Tim Stevens, product manager of embedded systems at FreeWave, said customer input prompted two new features with the GX product line: "LPA or Linear Power Adjustment and the addition of remote LED support to our embedded GXM products. LPA enables the output power of a GX to be specified in dBm, and a new backward compatible 24-pin connector option enables OEMs to add radio status LEDs to their products,” he added.

The GX-Line

GX line transmits data in the 2.4 GHz spectrum for international use. It is an alternative to the 900 MHz spectrum. This allows current North American customers with international locations to easily leverage their existing investments by communicating in one or both spectrums. The GX line is RoHS (Reduction of hazardous substance) compliant and ETSI (European Technical Standard Institute) labeled. The new line also offers the same proven features as FreeWave’s FGR2 900 MHz line of radios. Some of the key benefits and features include:

•     Long range – 20-mile range with clear line of sight.

•     Versatile – a single radio can operate as a master, slave, repeater or slave/repeater.

•     Unparalleled signal performance – technology built in for filtering that has unmatched combination of overload immunity and sensitivity.

•     Industry-leading, money-saving low power consumption.

•     Supported by FreeWave Tool Suite, a network diagnostics and radio configuration software.

Pricing varies, depending upon customer configuration.

Annual Salary Survey

After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.

The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
