IT The home of 7 month 4 Daily news , Ziguang zhanrui announces , stay 3GPP 5G R17 edition ASN.1 On the occasion of formal freezing ,2022 year 6 month 21 Japan , Ziguang zhanrui and Beijing Penghu Wuyu Technology Development Co., Ltd. took the lead in completing The first in the world is based on R17 IoT NTN The standard 5G Measured on the satellite Internet of things .
According to introducing , The satellite IOT terminal used in this test Based on purple light 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 .
IT Home learned , comparison R16 standard ,R17 The standard will cover vertical industry capabilities more comprehensively , On the edge of Computing 、 Basic capabilities such as network slicing are further enhanced , At the same time, the user experience will be guaranteed 、 Business model and other issues should be taken into consideration . As Rel-17 One of the main contents of the standard ,RedCap (Reduced Capability) It realizes the design of the medium and high speed IOT scene 5G Network service capability , Further expanded 5G Application scenarios and solutions .
