The Design and Simulation of a Smart Farm System Based on Ultra Narrow Band Communication

Article Preview

Abstract:

This paper presents a Smart Farm system, which is based on Ultra Narrow Band (UNB) communication technology. As to the characteristics of large area and high livestock mobility on the farm, using traditional communication technology have the problems of high cost, high power consumption and difficult power supply, however, UNB can achieve a high spectrum utilization efficiency and reduce the power consumption. At first, this paper introduces the Minimum Side-Band (MSB) modulation technology which is one kind of the UNB technologies. Secondly, the key issues of digital demodulation is discussed. And then, a MSB transmission system include digital modulation and demodulation is designed and simulated. Finally is the design of Smart Farm based on UNB technology and the summary of the whole work.
