Abstract

The invention discloses a vacant frequency spectrum Internet of things communication system and a communication method thereof. The system comprises a vacant frequency spectrum database, a vacant frequency spectrum frequency-band selection module, an upper and lower channel sub-carrier self-adaption module and a UNB communication module. The vacant frequency spectrum Internet of things communication system and the communication method thereof have the advantages that the technologies of scanning detection, frequency hopping and Ultra Narrow Band (UNB) are utilized, the cleaner frequency band of a television vacant frequency spectrum is utilized, the signal cover range with several kilometers or above is provided, the Internet of things communication requirement of several kilometers or above can be met, therefore, the cost of terminal hardware equipment and a network is reduced, the power consumption of a communication terminal is low, and the power supply environment of a button battery for an environment without a power supply is met.

Description

technical field [0001] The invention belongs to the technical field of digital television and wireless communication. In particular, it relates to a white spectrum Internet of Things communication system and a communication method thereof. Background technique [0002] The existing wireless Internet of Things communication system, in the range of a few meters or tens of meters, mainly uses ZIGBEE and WIFI technology, and the technology that is a little farther away can only be the technology of mobile operators. Indeed, judging from the current situation, mobile operators can be confident. Their 2G and 3G networks are currently the main bearer network of the Internet of Things. However, access to this network requires high equipment costs and expensive communication fees. In the face of a large number of terminals connected to the Internet of Things, the number of access is limited. [0003] Nowadays, due to the rapid development of technology, China's radio and televisio...
