Qorvo, a leader in providing innovative RF solutions for advanced wireless devices, wired and wireless networks and defense radar and communications has developed ConcurrentConnectTM multi-protocol technology, an approach that unifies network communication to ensure fluid and continuous networking across several IoT devices regardless of the protocols in use. Qorvo uses its QPG6100, a smart home communications controller that improves connection speeds and minimizes latency among wireless devices in the home environment while keeping network activities coordinated between many standards.
The State-of-the Art Technical Challenge
Although many IoT devices in the smart home include support for multiple protocols, most rely on time division multiplexing for communication. Time Division Multiplexing (TDM) is a communications process that transmits two or more streaming digital signals over a common channel. This works well for a minimum number of devices, but in more complex home networks, the inherent latency and potential for dropped communications create problems.
What Qorvo's ConcurrentConnectTM technology Offers
To illustrate the technology benefits with an out-of-the-box example, Qorvo used the sample lighting application from the QPG6100 development kit. Two networks — one Zigbee and another Bluetooth® mesh — simultaneously control red and blue LED light strips.
The red-light strip — representing Zigbee activities — is controlled using voice commands through an Amazon Echo device. The blue light strip is switch controlled through another QPG6100 board connected to the Bluetooth network.
In this lighting example demonstration, the voice commands to Alexa to turn the red-light strip on and off are processed at the same time the switch control turns the blue light strip on and off. As shown in this live video demonstration, these actions are carried out concurrently with no visible delays.
Even though Zigbee and Bluetooth mesh rely on asynchronous communication, low-latency network communication occurs with near real-time responsiveness. The capabilities of ConcurrentConnectTM make this possible by continuously listening for and receiving packets on both networks while responding to IoT devices promptly.
This level of interoperability enables effective control over a wide range of IoT devices.
