Ziguang zhanrui's first 5g R17 IOT NTN satellite in the world has been measured on the Internet of things

【TechWeb】7 month 5 Daily news , Ziguang zhanrui announced in 3GPP 5G R17 edition ASN.1 On the occasion of formal freezing , Ziguang zhanrui and Beijing Penghu Wuyu Technology Development Co., Ltd. took the lead in completing the world's first project based on R17 IoT NTN The standard 5G Measured on the satellite Internet of things , Opened based on 5G The new generation of Satellite Internet of things service mode , It also played 6G The preface of the network coverage of the integration of space and earth .

The satellite IOT terminal used in this test is based on Ziguang zhanrui IoT NTN Chip development , adopt L Band satellite , Completed the communication networking test on the pre commercial base station , And realize data transmission .

The satellite used in the test is a satellite located above the equator 36000 Kilometers of commercial geosynchronous orbit mobile communication satellite , Ziguang zhanrui has overcome the technical difficulties faced by the test terminal, such as long time delay and large attenuation , The communication distance with the satellite is as long as 38000 Kilometers , Successfully completed the broadcast 、 Access 、 Data transmission and other communication processes , And realize the networking test of multi terminal access and concurrent communication services .

The satellite Internet of things test terminal used in this satellite test , The transmitting power is 23dBm, Same as mobile phone , This means based on purple light zhanrui IoT NTN Terminal of chip development , It has low power consumption 、 miniaturization 、 Lightweight and other ease of use advantages , It can be widely used in a variety of IOT scenarios .

The success of the on-board measurement means based on 5G R17 IoT NTN The standard satellite Internet of things system technology is commercially available . future , Service providers can play the ground 5G Industrial chain advantages , Provide the global ubiquitous through satellites IoT NTN Satellite Internet of things , Provide competitive solutions for industry partners .

IoT NTN Technology can make 5G Large scale Internet of things and satellite networks are deployed in coordination , On the one hand, it extends the sea surface 、 airspace 、 Coverage of no man's land and other areas , It will effectively eliminate the digital divide between remote areas on the ground and developed areas , Promote the harmonious development of digital social economy ; On the other hand , So that satellite networks can share the industrial scale of mobile communication networks , Lower terminal and network costs , Make the terminal form smaller 、 Low power consumption and other ease of use , It provides technical support for the future large-scale Internet of things coverage .

As a rare global master 2G/3G/4G/5G、Wi-Fi、 bluetooth 、 TV FM 、 One of the enterprises of full scene communication technology such as satellite communication , Ziguang zhanrui always insists on taking technological innovation as the core , Continue to invest in the research and development of advanced technology , Keep breaking through 5G The border , Give Way 5G Technology plays a greater role in a broader field .
