Silicon Labs/Dusun Zigbee 3.0 Gateway with Long-distance Signal Transmission
Recently, Dusun Electron Ltd has successfully built an intelligent multi-functional gateway supporting multiple protocols by adopting Zigbee networking scheme of Silicon Labs. The gateway supports LTE-M (emtc), Wi-Fi, Zigbee 3.0, Bluetooth and Z-Wave wireless protocols.
As part of the new MICT (Mobile Information and Communication Technologies) strategy, ZTE established ZTE Health Co. Ltd, a high-tech joint venture between ZTE Corporation and Homing health care, headquartered in Shanghai. Its aim is to apply and commercialize ZTE’s health platform for the elderly people and to offer customers and their families the highest possible quality of life. ZTE wants to harness information technology and cloud services to increase the efficiency of the healthcare industry and meet the high-level, personalized requirements of consumers.
WeCare Solution Description
WeCare want to help elder people and their direct environment (children, friends, family) to take care of themselves, so that they can live at themselves longer and happier at affordable price, at safe circumstances, in a friendly environment, preferable their own home, at the same time, can meet their specific elderly needs and growing concerns. WeCare encompasses technical systems to support elderly people and people with special needs in their daily routine. The main goal of it is to maintain and foster the autonomy of those people and, thus, to increase safety in their lifestyle and in their home environment. WeCare home care scenario is characterized by being connected, context-sensitive, personal, adaptive and anticipative. The IoT is supposed to being capable of providing all characteristics necessary for an ambient assisted environment. With respect to the fields of needs for elderly people it is possible to accomplish all fields through the IoT.
Figure 1. WeCare Health Information Platform
WeCare solution is an intelligent platform for the elderly care service provider, with easy and friendly interface to get to know every elder people status. It provides centralized real time monitoring for multiple elders who living in the same building or different locations. It can be informed immediate if something abnormal, and being informed if the potential risk is going to happen. The above figure shows the WeCare health solution diagram. They use many BLE devices for health monitoring. BLE gateways collecting the data from BLE health monitoring devices and send the data to the weCare platform for further processing. Finally, the processed information can be reviewed by users and physicians through weCare mobile apps and platform viewer.
Dusun Products Used
Bluetooth Low energy (BLE) IoT gateway/hub
Support most connectivity IoT protocols. Dusun’s gateways support most standard internet connectivity protocols including MQQT, COAP, LMW2M, etc.
Support many connectivity types simultaneously. Dusun’s gateways can connect Bluetooth(BLE), and ZigBee, ZWave devices in the same time.
Dusun BLE gateways have the ability to provision, update and control access of connected devices.
Dusun’s BLE gateways/hubs take many known measures to counter communication and physical attacks. They support common encryption algorithms, hash algorithms, authentication ways.

ZTE Health Wecare System Scenario
WeCare Mobile Apps (above figure) provide alarming for some abnormal and emergency, including emergency help, no room activity was monitored, sleeping late notification, returning home late notification, getting up late notification, abnormal toilet activities. It can also monitor users’ realtime daily activities in house, some Important events include going to/out of bed, in/out of home, moving or not in houses, meals.
The Wecare App can also evaluate Health Assessement Evolution from 5 different aspects. A series of detailed data includes activity, sleep quality, heart rate and respiration rate, heart rate, HSV, toilet etc. It will self-learn of the individual elderly’s habits and health status, and predict individual health status.
Base on the same intelligent platform (above figure), weCare also provide extension smart home functions, including Smart thermostats, radon equipment, smoke alarming, oxygen quality monitoring, window and door operations, ventilation system, smart door locks and doorbell, security cameras if required. The platform enables full automation and does not need manual operation or remote control.
Why Dusun Products
IoT gateways sit at the intersection of IoT systems -connected devices, controllers and sensors - and the cloud or platform. It plays an important role in the AAL system. Dusun’s IoT gateways have the following products functionality and advantage:
Great BLE performance. Great BLE performance makes it suitable for connecting many BLE smart health monitoring sensors. BLE is an open standard and is supported by most mobile phones. BLE ensures the interoperability of products from different manufacturers. The gateway supports BLE 5.0 and BLE Mesh protocols.
Programmable and good chip-level support. Dusun smart gateways are programmable and SDKs and APIs are provided which can be used to let customers make their programs to control the data transfer procedure and use their security mechanism. The programmable ability lets China mobile and its partners embed Dusun’s gateway easily. Dusun provides chip-level technical support for their application.
Support ZigBee and Z-Wave in the same time. This feature let ZTE-health connect different types of IoT sensors for building their system. ZigBee and Z-wave are IoT’s important protocols.
Dusun has developed BLE devices for more than 6 years. We cooperated with some companies which are devoted to design BLE health sensors and devices. The BLE health devices manufactured by Dusun has the following features:
Support BLE 4.2/5.0. The sensors support the most updated protocols to suit for ZTE health needs.
High cost performance ratio. The BLE health devices are manufactured by Dusun itself, but designed with several companies which have rich BLE health devices design experiences.
