To many, radio remote technology seems simple. What they do not understand is that it is essential that you can rely on it. Always. It places great demands on the manufacturers. Their whole business is at stake if something goes wrong. Hence, Scanreco assures that we are in the very forefront of technology. We are one of the pioneers within the industry and a safe and reliable radio link has always been our biggest concern. That is also an important part in our promise for Never-Stop Technology. Products from Scanreco work – no matter what.
One of our experts in wireless technology, Dr. Andrei Sazonov, originally from Russia with a doctor’s degree in radio technology, guides us through the basics.
– “There are different aspects of reliability. Of course, the signal must work reliably between the transmitters and the receivers and, in the worst case, instantly stops everything if something unexpected happens,” Andrei starts.
– “However, the biggest issue is that a wireless control system almost never works alone. There are multiple appliances that use the same frequency bands, such as 2.4 GHz, 433 MHz and 915 MHz. This can cause interference that can stifle and block any “lower end” radio terminal and cause substantial performance issues,” says Andrei.
– “Scanreco use three important technologies that make performance issues unlikely to happen. Direct Sequence Spread Spectrum (DSSS) is a very robust technology against radio signal interferences. It is also a way of giving each pushbutton an encrypted bit stream. When the pushbutton is activated by the user to enable a machine function, the robust encrypted bit stream improves the resilience of the system. Thus, impairment of a few bits in the bit stream does not damage even a single bit in the key code,” Andrei explains.
– “Another solution that strengthens the reliability is Frequency Hopping Spread Spectrum (FHSS). This continuously switches the radio signal among at least sixteen frequency hopping channels as a layer of redundancy. It protects the equipment against frequency-selective fading and ensures an adequate signal-to-interference ratio in the midst of other aggressive wireless devices. The system avoids interferers by simply hopping to the next channel,” Andrei says.
– “The third solution is a proprietary collision avoidance algorithm. The different techniques combined guarantees sufficient signal-to-interference-plus-noise ratio and increases the system reliability and availability in the harshest radio conditions where stable wireless control of machinery is critical,” Andrei Sazonov finishes.
Never-Stop Technology is the expression for what to expect from products from Scanreco. A reliable wireless control system is at the heart of it.
– “For many years, we have given young people a chance to try work life for a few weeks in the summer in Scanreco Next Generation,” explains Ann Lapidus, VP HR at Scanreco.
– “It is not easy to get a job during summer breaks and we find it very meaningful and a good way of contributing to our society. I think it is important to get an idea in the early years of what working life means. We offer adolescents between 16 and 19 years of age a summer job and this summer Scanreco will host 10 young adults,” Ann tells us.
– They do what they can do to contribute and also to learn, including simpler tasks constantly monitored by a sponsor often in the warehouse or production. They get a contracted salary and an opportunity to learn something everyone does not get a chance to do,” ends Ann Lapidus.
On the 13th of June 2017, the new RED (Radio Equipment Directive) replaced the old R&TTE Directive (Radio & Telecommunication Terminal Equipment), implemented in 1999. Every company that produces equipment with a radio system is required to abide to the RED, Pär Ljunggren, Product Manager at Scanreco, helps us get it right.
– “It is important to understand that the RED covers only new products; spare parts for older systems are not affected. They follow the old directive. To Scanreco, this means that we will be able to support our legacy products, e.g. the G1 platform products” says Pär.
– “One focus point for RED is traceability, it enforces higher demands on all actors on the market (producers, distributors, integrators), to be able to trace all products under RED. Another difference is that from now on, the machine the radio is integrated with must follow the RED, which places new demands on many manufacturers and integrators.” he continues.
– “RED is a directive and an umbrella that points out several important standards that must be followed. Still every aspect is not covered; we are awaiting the final decisions. Hopefully, the last standard under RED will be approved in September 2017,” Pär explains.
– “What I am mostly concerned about is, of course, our products. Herein can ease any fears. RED does not mean any differences to our products themselves; they remain unchanged. With the same article number, nothing changes,” Pär Ljunggren finishes.
