Since August 8, the middle and lower reaches of the Yangtze River in my country have experienced heavy rainfall, especially in many places in Hubei, which have experienced extreme weather ranging from heavy rain to heavy rain, heavy rain, and then extremely heavy rain. Not long ago, the “7.20” heavy rainstorm disaster in Zhengzhou, Henan also caused heavy casualties and property losses.
In the face of extremely catastrophic and harmful extreme heavy rainfall that occurs frequently during the flood season, it is very important for the front line of disaster relief to understand the disaster situation in a timely and accurate manner. Therefore, the communication between disaster relief personnel must be stable, reliable and timely to ensure the smooth progress of the rescue work. . Public network walkie-talkies have played an indispensable role in the rescue work.
The coverage of traditional walkie-talkies is generally 1-5 kilometers, and group communication requires frequency modulation, which is inconvenient to use. The public network walkie-talkie PoC (Push-to-talk over Cellular) runs on the 4G network and is not limited by distance. The operator’s signal coverage area can be freely intercom and call, meeting the needs of instant calls for cross-regional and long-distance coordination operations;
Relying on digital signals, the sound quality and volume are clear, and the multimedia functions are rich, which can realize the transmission of voice, video, data, etc.;
It supports the positioning function, which can intuitively display the real-time location of the staff, grasp the trend, and in an emergency, the staff within the area can be dispatched to handle events in real time.
It is reported that during the rescue process of the heavy rain disaster in Henan, Henan Baolan Industry has a total of more than 5,000 public network walkie-talkies of various models to provide Zhengzhou Mining Bureau, Xuchang Urban Management Bureau, Luoyang Railway Bureau, Xinxiang Telecom, Taxi Company and other units and institutions. Communication support. Among them, several models of public network walkie-talkies are equipped with Neofang Technology Cat.1 wireless communication module N58.
N58 is the world’s first Cat.1 wireless communication module based on LTE Cat.1bis IoT dedicated chip Ivy V8910DM. With the differentiated advantages of stable and reliable communication, it is used in public network intercom, payment terminal, Internet of Vehicles, energy metering, sharing , device management and other scenarios.
N58 operates on the LTE network with the widest coverage in the world, supporting mainstream frequency bands in key areas;
Provide 10Mbps downlink and 5Mbps uplink data rate, which is the preferred communication solution for medium-speed IoT terminals;
Low power consumption, ultra-wide operating temperature (-40℃~+85℃), suitable for high temperature/cold application scenarios, especially industrial environments, and application scenarios with large temperature difference in the north;
The unique Bluetooth and Wi-Fi Scan functions, as well as the MOTA+FOTA function, make the product not limited by distance and realize fast maintenance and upgrade.
As a leader in the public network intercom industry, Henan Baolan has a self-developed intercom platform with compact products and rich functions. Over the years, Neoway and Henan Baolan have continued to cooperate in research and development to provide customers with stable and reliable communication terminal products and continuously improve customer value. In the era of Internet of Everything, Neoway will continue to make efforts in the public network intercom industry to provide stable and reliable instant communication for public security, firefighting, transportation and other departments, so that communication can be warm and rescue can be more timely.
Neoway Technology focuses on providing IoT access communication products and related services for industrial IoT service providers, smart connected product manufacturers and other customers. Products cover access cloud, pipeline cloud, 2G/3G/4G/5G/NB-IoT/eMTC and other wireless communication modules and terminals. It is precisely based on the systematic solution of cloud-pipe-terminal access communication pioneered by Neoway in the world, the company can provide more stable and reliable access communication for the Industrial Internet of Things. In this way, the value of the Internet of Things to human society in terms of environmental protection, efficiency and convenience can be more effectively improved.
