Working Principle of Lightweight DSGW-340 Medical BLE Gateway

Take a Blood Pressure Monitor as an example, BP monitor connects with the DSGW-340 BLE gateway by BLE protocol. A single Bluetooth gateway can connect many BLE medical wearable devices (meaning users can also connect pulse oximeter or ECG sticker together). The data of the these BLE-based end medical devices will be uploaded to the server via LTE/Wi-Fi.
As a result, the data from these medical devices can be managed by the professionals remotely on PC or mobile devices.

FAQs of DSGW-340 BLE to LTE/BLE to WiFi Gateway

As you can see from the Silicon Labs’ introduction, EFR32BG24 uses using Bluetooth Low Energy connectivity and is intended for portable medical products. It features high performance 2.4 GHz RF, low current consumption, an AI/ML hardware accelerator and Secure Vault™, easily for IoT device makers to create the smart, robust, and energy-efficient products that are secure from remote and local cyber-attacks. For more info, you can explore here.

Both Bluetooth and Zigbee are good options for medical wearables. Bluetooth is widely used in consumer electronics, like mobile phones, and has low-cost advantages. It is the priority choice for medical devices to connect with users’ mpbile phones. Zigbee does not enjoy this level of interoperability, although it is widely used in smart home gadgets. On the other hands, compared with Zigbee, Bluetooth has faster transmission spped in small data packet.

Bluetooth gateway is used for continuously uninterrupted data transmission, which is hard to be done by a single medical wearables, because these devices usually use Bluetooth or Zigbee, failing to generate its IP (Internet Protocol) address, which means no direct access to the Internet. Bluetooth gateway help build a bridge for medical wearables, so their sensed data can be send to cloud platforms of healthcare providers for further analysis and diagnosis.
