Industrial Wireless Connectivity Technology

Wireless Connectivity for Industrial Applications

Wireless communications have been used in industrial applications for many years, with basic controls of cranes and other moving devices among the first deployments. The implementation of a more standardized wireless connectivity technology in recent decades has increased deployment into a broader range of end equipment.

In industrial applications, no single wireless technology is king. Low bandwidth and low power technologies are best for meter deployments with occasional connectivity needs. In contrast, for autonomous guided vehicles (AGV) deployed in busy factory floors with multiple sensors communicating simultaneously and continuously, higher bandwidth options are needed.

Analog Devices’ range of wireless communications technology enables connectivity to sensors in remote and hard-to-access hazardous locations without the need to deploy a wired network. ADI offers highly advanced wireless subsystems and complete signal chain solutions focused on reducing the design burden and speeding up deployment. These solutions include SmartMesh®, 5G, Bluetooth® low energy (BLE), and 60 GHz latency-free wireless data interconnects. If you want a reliable wireless connectivity, ADI has the proven technology to get you started today.

60 GHz Latency-Free Wireless Data Link

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.

Key Benefits of ADI’s 60 GHz Technology

Ultralow Latency

Wireless is known for latency-inherent networks. Wi-Fi can produce 20 ms latency for Ethernet transmission, while 5G is targeting 1 ms. With 60 GHz links, the latency is in the 2 µs range, orders of magnitude faster than 5G.

Offset and Alignment Tolerant

To enable a versatile assembly and operational environment, ADI’s 60 GHz link technology does not suffer loss in performance when wireless connectors are misaligned. Due to this offset and alignment tolerance, this technology can be used in rotation equipment without impacting the performance of the link, thereby replacing the more traditional wired contact systems.

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.
