The embodiment of the invention discloses a gateway physical layer of a narrowband Internet-of-Things system. The gateway physical layer of the narrowband Internet-of-Things system comprises a first kernel processing module, a second kernel processing module and a modulation-demodulation module. The first kernel processing module is used for system frame period configuration, downlink air interface data processing and air interface data processing of a first uplink channel; the second kernel processing module and the first kernel processing module work cooperatively and are used for air interface data processing of a second uplink channel; and the modulation and demodulation module is used for modulating and demodulating air interface data through a radio frequency transceiver of the gateway. According to the gateway physical layer of the narrowband Internet-of-Things system, system processing of air interface data is performed through the two kernel processing modules so that high performance of gateway data transmission can be guaranteed, performance requirements of the gateway can be met and thus deployment cost of the gateway can be saved.
Description
technical field [0001] The embodiment of the present application relates to the technical field of communication, and in particular to a gateway physical layer of a narrowband Internet of Things system. Background technique [0002] At present, in many areas of life, the Internet of Things technology has been applied to build communication networks. Generally speaking, in the Internet of Things systems in these fields, various wireless networking methods are usually used to form a network within a certain area, and then arrange several data concentrators or intelligent gateways at appropriate locations. However, in some IoT systems such as smart meter reading and smart cities, the number of terminals that need to be connected is relatively large, and the network coverage distance is relatively wide. The IoT system using ZigBee, WiFi networking or LoRa networking requires additional relay equipment for data jump transmission, and the cost of system setup investment is relati...
