Industrial Wireless Connectivity Technology
Bluetooth, WLAN, and 5G are all effective ways to transmit and receive data. However, all packet-based wireless connectivity standards have one issue in common: latency across the link. Therefore, communication is not real-time. This can impair the reaction time of a piece of machinery from when an instruction is created to when that instruction is received and executed. Industrial automation uses real-time protocols (for example, EtherCAT), which require negligible latency for communications, so the wireless link must provide a latency-free connection.
The solution is to remove the packet-based transmission protocol and migrate to a bit stream that is sent directly. This technology brings to life the possibility of a true wireless data link for robot arm interconnect, which is hundreds of times faster than the fastest 5G connection.
With the increased investment in robotics to harness automated processes, ADI delivers the solution to enable industrial efficiencies and reduction in work errors. Latencies that could stack up over time and create a large cost to the factory are no longer a consideration using real-time wireless links.
Ruggedness Against Dusty Environment
The 60 GHz links are unaffected by dirt and debris between the connectors. This means that a 60 GHz solution can be used in the harshest of environments without loss in performance.

Contactless Slip Ring Replacement Applications
A 60 GHz wireless link technology is highly suitable to replace the existing slip ring technology. Slip rings are used in rotational joints (rotary joints) and can serve to transfer data across a rotating assembly. This is traditionally done using brushes, which make physical contact to a rotor. But brushes break down over time and require repair and replacement. Depending on the assembly in use, this can be costly, especially when large assemblies need to be repaired or replaced. Also, the routine maintenance involved in verifying correct assembly operation can be tedious and expensive. Using ADI’s 60 GHz link technology removes the physical contact and enables the rotary joint using a contactless method, reducing routine maintenance, repair, or replacement.
