In order to receive Wiliot IoT Pixel data, two functions need to be addressed: providing energy for the Pixels to harvest from, and receiving data packets to send them to the Wiliot cloud. This includes Bluetooth bridge devices, Bluetooth to Wi-Fi gateways, Dual-band gateways, or even BLE-enabled devices like smart appliances or smart home systems. In certain applications, one device can be used to provide energy and relay data packets, while another such as a smart phone can receive the data packets and route them to the cloud. The vision as Wiliot continues further into its technology development is for IoT Pixels to harvest from and transmit to existing infrastructure and/or smart phones.
In many Wiliot Solutions today, energy is obtained by Bridges and Gateways. We commonly use a 'Three Tier Architecture'- it goes as follows:
1. Pixels can be on items or containers
2. Bridges are low cost devices that extend range, allow transmissions from many tags to be filtered to Gateways. They:
- Energize – Providing energy for Wiliot Pixels to harvest
- Read – Recognizing Wiliot Pixel data packets and forwarding them to the Wiliot Cloud
- Repeat – Select & repeat amplified Bluetooth broadcasts to Gateways
3. Gateways – Relay from Bluetooth to WAN
Bridges and Gateways work with the Wiliot cloud to manage traffic & energy intelligently
When using a mobile phone as a gateway - does it recieve the data transmitted directly from the IoT Pixel or from the bridge?
