The massive deployment of wireless devices in industry has exploded over the past few decades. With all these new wireless connections in the same space, their ability to operate in this environment is often referred to as radio coexistence. This is becoming a major concern for the IoT.
Also, cases of interference have highlighted the phenomenon of radio coexistence which is becoming increasingly important with the massive deployment of connected devices. Although taken into account by the EMC and radio standards applicable in the context of CE marking, the notion of limiting out-of-band radiation is of great importance here.
For example, several studies have highlighted the likelihood of interference between #4G signals (832-862 MHz) and short-range #SRD devices (863-870 MHz), focusing more on the risk of interference to nearby SRD equipment (wireless headsets and microphones, alarms, remote control varieties…) from 4G signals in the adjacent high band.
To address these concerns, Radio and EMC requirements are evolving to provide standards-based radio coexistence tests that specify key performance indicators that can be used to assess the ability of the equipment under test to coexist with other equipment in its intended operating environment. Bluetooth, Wi-Fi, LTE, 5G, RFID,… are the main technologies and bands increasingly covered.
At LCIE, our experience through testing, EMC and Radio expertise allow us to support manufacturers and installers, facing these risks that may concern a multi-frequency product, or when equipment operates in close proximity.
In this webinar we will discuss the phenomena of radio coexistence that occur today depending on the technologies used and how this is taken into account in radio and EMC standards, particularly in environments such as medical, industry and transport.
