Confused on what frequency to use for your wireless control application?
Different radio frequencies have distinct properties that cater to individual industrial applications.
Beginning to understand the world of wireless technology more clearly means the surfacing of new and different applications for wireless communication. Even though a broader spectrum of wireless capabilities is on the rise, many companies offering wireless control products continue to carry operations on only one frequency and inform their customers that it is the best frequency for their application. This is simply wrong information.
The correct fact is that different radio frequencies (RFs) possess different properties, and it is inaccurate to state that one frequency is best for all wireless applications. In terms of RF, as the frequency increases, the need for line-of-sight increases; however, the resistance to electrical noise also increases. The higher the frequency, the more complicated the data that can be transmitted. Therefore, if one needs to send simple on/off signals far distances, such as when controlling a well pump from a remote storage tank, a frequency of 27 MHz would be optimal. No line of sight would be necessary. If a person wishes to transmit complicated data over a shorter distance, such as when using multiple units in a factory to constantly send data back and forth between machines, a product operating in the 900 MHz band and higher would be favored.
Remote Control Technology (RCT) currently has several frequencies available for wireless control and telemetry. While working with the specific needs of their clients, RCT Account Executives suggest a product that operates on a frequency that best fits the customer’s application. RCT offers frequencies in the range of 27 MHz to 900MHz/2.4GHz depending on the range the client seeks, whether he or she has line of sight, etc. Custom frequencies for clients are even available upon request.
Yuba County Water Agency’s Communication Technician, Scott Novak, needed a simple automated control for a water pump that was a mile away from the holding tank that it filled. Due to the presence of a reservoir and ridgeline between the pump and the tank, conventional RF line-of-sight control was not an option. RCT provided Novak with a Medium Range Wireless Switch System (MRWSS), which is a low-band, VHF controller that does not require line of sight to operate.
“The MRWSS solved all of the problems presented by this project,” Novak states. “Remote control was obtained over a large body of water and around a ridgeline where landline and conventional line-of-sight UHF control were unsuitable. The low-band VHF signaling easily followed the terrain and provided a full-strength signal as indicated on the receiver.”
Scott Novak faced a problem that high-frequency, line-of-sight control was not able to fix. However, RCT was able to provide Novak with a simple wireless solution for non-line-of-sight control to solve his problem. One specific frequency is not ideal for all wireless applications, and RCT provides options for wireless control and telemetry on a case-by-case basis.
For over 25 years, Remote Control Technology has been a leader in innovative applications for wireless radio frequency (RF) remote control and telemetry devices. We employ a unique customer and application-focused engineering as well as a systems-integration discipline, which enables us to manufacture wireless switching and telemetry devices to meet many diverse customer requirements in a timely and cost-effective manner. Remote Control Technology has designed and manufactured custom wireless systems for Exxon/Mobil, Raytheon, Boeing, Ford, and other Fortune 500 companies, as well as prototypes and small-run production systems for many domestic and international businesses. Anything that can be switched (i.e. on / off and forward / backward) or that can send and receive data can do so wirelessly.
