Recently, the NB-IoT wireless smoke alarm developed by 777 IOT (a well-known domestic IoT brand) has been successfully piloted in Xiong’an New District. It has become the first batch of NB-IoT smoke devices in Xiong’an and will be fully promoted in Xiong’an. It is reported that the device adopts the NB-IoT module ME3616 of GosuncnWelink Technology Co., Ltd. (“GosuncnWelink”) which provides safe, reliable and stable connection services for real-time transmission of smoke data.

As a national new district, one of the seven key tasks under Xiong’an Construction is to “build a world-class, green, modern and smart city” and create a “sample room” for smart cities throughout the country. In particular, smart firefighting and the smart municipality will firstly be settled. The market demand for intelligent smoke alarms, real-time monitoring cameras, temperature, and humidity sensors raises significantly.

Nowadays, the traditional independent smoke alarms on the market have a single quality function without networking and only issue sound and light alarm. The NB-IoT wireless smoke alarm of 777 IoT has a built-in NB-IoT module ME3616 provided by GosuncnWelink, which can report fire alarm information to the remote monitoring platform in real time through the wireless mode. The product has obtained CCCF certification for national fire compulsory products and is in line with standards, safe and reliable.

The wireless smoke alarm can overcome the shortcomings of troublesome traditional smoke alarm wiring, be installed independently and realize wireless networking. If NB-IoT is adopted, gateway deployment will not be considered during the actual installation, which saves deployment cost and can access the platform in one hop. Based on the NB-IoT network, it avoids the risk of missing and false reporting caused by a traditional smoke alarm. It has such advantages as low cost, easy installation, easy maintenance, safeness, and convenience, which will greatly improve fire construction efficiency and wisdom level.

The wireless smoke alarm is generally powered by built-in batteries, and it is installed inside the building. It needs to cope with long-term battery life, harsh and complicated wireless signal environment. At the same time, a lot of deployments will require a reduction in the overall cost. IoT ME3616 module of GosuncnWelink has the following high performances, providing perfect solutions for the wireless smoke sensor of 777 IoT in terms of power consumption, communication coverage, and cost.

Ultra-low power consumption: ME3616 supports PSM and eDRX modes, and the PSM mode is suitable for data transmission of smoke devices. In PSM mode, ME3616 consumes as low as 2.6μA, and its power consumption is significantly lower than other products on the market. It can ensure that the wireless smoke alarm works continuously for 3-5 years.

Deep coverage: NB-IoT technology increases a gain of 20dB when being compared to the original LTE. In the actual measurement, when the receiving sensitivity RSRP reaches -140dBm, the competing module communication will be invalid. However, ME3616 can still make data service stable and reliable, ensuring that the smoke device can work stably and reliably in any indoor place, basement, and pit.

Solution-level optimization and super cost-effective: ME3616 integrates OpenCPU solution to achieve solution-level optimization, reduce the material quantity and development complexity and help 777 IoT reduce the overall cost by about 20%.

Excellent characteristics of ME3616 are reflected well in the practical applications of Xiong’an New District, and it has been highly accepted and recognized by users.

As a leading provider of integrated IoT solutions, GosuncnWelink focuses on the wireless connection in the IoT industry, providing safe, reliable and quality wireless connection and services. This time, GosuncnWelink cooperates with 777 IoT to successfully pilot the first batch of NB-IoT wireless smoke alarms in Xiong’an New District, which will push the construction of “Smart Xiong’an” a big step forward. In the future, GosuncnWelink will strengthen the cooperation with upstream and downstream enterprises and increase investment in the NB-IoT field so as to accelerate the development of China’s IoT industry.
