Many connected devices can improve consumer experience and enhance functionality by supporting multiple wireless connectivity options. We are used to our smartphones supporting Bluetooth, Wi-Fi, and other connectivity options to provide streaming media as well as connectivity to headphones and smart watches. The power, size, and cost requirements for many IoT systems has traditionally made supporting multiple protocols challenging. Dynamic multiprotocol wireless connectivity provides a viable means to simultaneously support multiple wireless protocols on a single chip by using a time-slicing mechanism to share a radio between protocols, reducing wireless system cost and simplifying system design.
Benefits of Supporting Multiple Protocols
- Provide direct phone-based configuration and control of connected devices
- Simplify wireless-subsystem design through reduction of RF components
- Include diagnostic capabilities to check device health with a smartphone
- Leverage multiprotocol IC for mobile engagement applications
- Add a mechanism for high-speed OTA firmware updates
Applications for Multiprotocol Connectivity
The usefulness of connected devices in consumer, commercial, and industrial environments can be enhanced or improved through multiprotocol connectivity. In home automation, for example, Zigbee provides whole-home wireless coverage with its mesh capabilities and makes it possible to control devices from outside the home via a gateway. When Bluetooth LE is introduced, a smartphone can be used for direct local control and location awareness can be added.
Sub-GHz wireless technologies are ideal for smart metering applications since they propagate over wide areas. By adding simultaneous sub-GHz and Bluetooth communication to metering IoT devices, technicians can utilize mobile apps for local setup, information gathering, and maintenance.
In retail or commercial settings, there is a desire to make use of technologies such as Bluetooth beacons to provide location-based advertisements, track assets, and develop heat maps to track foot traffic. By integrating Bluetooth beacons into connected infrastructure such as lighting, large-scale coverage areas can be created. Instead of having to deploy both connected lights and beacons, a light or luminaire can serve as the means to deploy Bluetooth beacons. This provides a more cost-effective avenue to enable location based services.
