Bluetooth 5 Poised to Take On IIoT Deborah Ray

Wireless communication solutions are not a new in industrial workspaces—they’ve been in use for more than 30 years, replacing wired networks and Human Machine Interfaces (HMIs), for example. Industrial workspaces, however, pose a variety of barriers to using wireless solutions: The number and types of sensors needed, communication speed, length, and frequency requirements, building configurations, Radio Frequency Interference (RFI), and Electromagnetic Interference (EMI), among other factors.

Several capabilities introduced with the Bluetooth 5.0 spec will enable Bluetooth 5 to meet the demanding communication needs of industrial environments: Increased speed, longer message length, increased bandwidth, ability to coexist with other wireless devices and frequencies, and mesh networking capability. But wait. Isn’t Bluetooth geared toward short-range, consumer-oriented wireless communications? That was then. Bluetooth 5 offers potential in IIoT for a number of reasons:

  • Bluetooth is already incorporated into smartphones, tablets, and laptop computers, so devices needed to create and manage the wireless network are already in use.
  • Mesh networking allows an unlimited number of Bluetooth-enabled devices to communicate, so the total range of a network is effectively unlimited.
  • Mesh networking, along with Bluetooth 5’s increased speed and bandwidth, can provide near-instantaneous round-trip communications, such as between machines on a production floor.
  • Increased speed and bandwidth allow sensors to be updated much faster and much more frequently, which is critical for ensuring that every device in the network has the latest security features and most current firmware.
  • Slot Availability Masks detect and prevent interference from other cellular networks and devices using the same frequency.
