Bluetooth would also be a poor choice for security solutions that require visual, audio, or biometric information to be published through the network given the load such data types place on the network. Bluetooth’s 2.4 GHz signals don’t penetrate water well. For example, it wouldn’t work well for tracking underwater assets in a harbor or on an oil rig. Like all connectivity solutions, Bluetooth is no silver bullet. Click To Tweet When Bluetooth Falls Short For example, 2.4GHz doesn't work well under water. Well-designed #IoT networks are effective for scenarios like indoor asset tracking. But the same Bluetooth solutions would be suboptimal for achieving other business goals. Properly-designed Bluetooth IoT applications are effective for such indoor asset tracking scenarios given the low-power requirements, theoretically infinite scalability, and self-healing reliability of emerging Bluetooth mesh networks. Maybe you’re trying to keep track of equipment, personnel, and patients as they weave through a hospital building. open/close or simple active/inactive messages) over the network, or do you think you need to transmit large raw files like audio or images over the network? It’s critical to explore these questions-and many others there’s no room to mention here-before falling prey to the marketing hype around one mode of connectivity. So what are you trying to accomplish with IoT? What are the particularities of your business, your industry, your services, and the spaces in which you, your employees and your customers operate? Are you trying to track things or people indoors, outdoors, or across the boundary of the two? Will you have power readily available, or do the devices need to be battery-operated? Do you need to send small packets of data ( e.g.
Bluetooth over LPWAN or NB-IoT over LTE-M-make sure first to first identify and articulate in clear terms the business objectives inspiring your IoT initiative. When choosing one mode of connectivity over another- e.g. Image Credit: EE Times Using Bluetooth IoT Applications to Achieve Business Goals Bluetooth will only continue to become more important as the SIG refines its industrial offerings: Bluetooth Low-Energy (BLE) and Bluetooth mesh (more on those shortly).
The group has since taken on a life of its own as we’ve embedded Bluetooth technology into our everyday routines worldwide. In 1998, Haartsen played a key role in creating the Bluetooth Special Interest Group (SIG)-a standards-setting body like 3GPP and LoRa Alliance. Haartsen disrupted that standard by using short-wavelength UHF radio waves in the Industrial, Scientific, and Medical ( ISM) band from 2.4 to 2.485 GHz to send small and simple data packets (“messages”) over short distances of a few meters.
He envisioned the technology as an alternative to the RS-232 data cables that since the 1960s had been the standard for connecting computer peripherals to PCs. From Cables to Mesh: Bluetooth at a Glanceīluetooth has come a very long way since Jaap Haartsen, an electrical engineer, invented the technology in 1994 while working for Ericsson in Lund, Sweden. Bluetooth powers a wide range of products in our homes and daily lives, like headphones, mice, and keyboards, as well as enabling us to transfer data over short distances, like Airdrop. Though you might not know how exactly how Bluetooth for IoT works or what applications it’s best for, you’re probably familiar with some of the underlying technology. Bluetooth is critical to IoT, enabling the transfer of data through mesh networks in a variety of settings.
