Data Radios

Radios designed for data communications are built to be rugged and dependable, with a variety of uses across the spectrum of industrial applications. Although 'SCADA systems' may not be ubiquitous in everyday life, radios used in these types of setups offer precisely the kind of robustness needed to make reliable operations possible—whether inside or outdoors. While they may not always receive sufficient spotlighting to illustrate just how varied their industrial applications truly are, such as OEM applications and SCADA systems, these radios do put forward a consistent facet of 'reliability first' whenever and wherever they're deployed.

High-speed data transmission is one of the key features of data radios, and that defines them. Telemetry systems rely on real-time data collection and control to function correctly – or at least, as efficiently as possible. So, in order to achieve this continuous real-time operation, many telemetry applications employ data radios operating on specific frequencies (like VHF and UHF) known for their endurance in transmitting valuable information over long ranges.

More Information about Data Radios

The selection of ports corresponds among different data radio types, giving us alternatives for inputs and permitting some flexibility in system setup. Yet, we have systems that seemingly work to the contrary—those with so many control features they can do almost everything. Advanced models offer a lot of options when it comes to managing data flow and communicating with other systems. They let us exert quite a lot of control over how this whole thing works together and be quite hands-on with it as well. Port options vary among different types of data radios, allowing for multiple alternate inputs that provide some flexibility in system setup. Some newer products seem to introduce even more controls comprising various settings that might give us a bit more peace of mind (or an increased sense of panic) concerning our whole system's operation.

FAQs

What gives data radios their high reliability when they transmit data over a network versus other radios or devices?

Data radios achieve high reliability in transmitting data over a network due to their robust error correction protocols, frequency hopping capabilities, and advanced modulation techniques that minimize interference and ensure secure, accurate data transmission over the long run.

Serial vs Ethernet Radios

There are many different communication protocols that can be used when selecting a radio. The type of protocol being used may depend on the application, time frame the hardware was installed, existing hardware that is already in place and many other factors. What is important to understand is that most of these protocols fall into two generic families: Serial-based protocols or Ethernet-based protocols. Examples of Serial-based protocols include: Modbus RTU, RS-232, RS-485 and Profibus. Examples of Ethernet-based protocols include: Modbus TCP, Ethernet IP and Profinet. The differences that exist in these protocols has a lot to do with data transmission speeds.

Serial-based protocols have a much more limited data transmission capacity compared to Ethernet-based protocols, however, they do not require a connection strength as strong as Ethernet-based protocols. This is beneficial in situations where the radio connection may be limited because of physical obstructions or long distances. Ethernet-based protocols have faster data transmission capabilities and are becoming much more common than Serial-based protocols. By understanding the differences between these two types of protocols, you will be better equipped to select the radio that will work best for your specific application.
