Olsbergs found in Digi a partner that could meet both these needs. The requirements for the radio module that Olsbergs needed were strict. They needed a radio module that would be precise and risk-free. Many cranes that would be operated by these remote controllers operate in cities and others populated areas. To ensure the safety and accuracy of the radio remote control it would have to meet ETSI standards and it would have to utilize the entire ISM band. That means frequencies 863 to 870. By utilizing the entire ISM band it would provide more channels to use and a more secure radio link. With these requirements in mind, John Fröde said that Olsbergs looked “probably somewhere between six and nine months for a stable partner, and we found it in Digi. Digi is a large and stable company that’s been around for more than 30 years. Their field engineers had really good answers to all of my questions. That’s why I was confident.” The solution to Olsbergs’ problem was the Digi XBee 868 Low-Power RF module for Europe. ETSI standards say that if you want a module that utilizes the entire ISM band then you need to have LBT and AFA. LBT is “listen before you talk” and AFA allows the radio to automatically jump between radio channels. The XBee 868LP uses both. With this module in their radio remote control, it means that Olsbergs can guarantee both the safety, accuracy, and reliability of their radio control hydraulics.
