Method for building path loss model in short-distance internet things environment

Abstract

The invention relates to a method for building a path loss model in a short-distance internet things environment, comprising the following steps of: building an original test data optimizing and acquiring scheme of a short-distance internet things environment path loss model; building the path loss model by a novel path loss model building scheme for evaluating short-distance internet things environment path loss characteristic; and evaluating a path loss model parameter by a novel path loss model parameter evaluating scheme for evaluating the short-distance internet things environment path loss characteristic. According to the method, the short-distance internet things environment path loss characteristic can be effectively evaluated, and the path loss evaluating deviation can be obviously reduced.

Description

technical field [0001] The invention relates to the technical field of wireless channel research, in particular to a method for establishing a path loss model in a short-distance Internet of Things environment. Background technique [0002] At present, the Internet of Things has become a leading field for countries all over the world to build a new model of economic and social development and reshape the country's long-term competitiveness. Developed countries have accelerated the development of the Internet of Things through measures such as national strategic guidance, government R&D investment, global promotion of enterprises, application pilot construction, and policy and legal guarantees to seize the strategic initiative and development opportunities. After years of hard work, our country has also established a certain Internet of Things application, technology and industrial foundation. In 2009, the Internet of Things was officially listed as one of the five emerging s...
