Description
Technical Field

Background
With the development of communication technology, the residential electric energy collection system gradually develops from an early stage by adopting a power line narrowband carrier communication technology to a micro-power wireless communication technology and a power line broadband carrier communication technology. Different communication technologies have respective advantages and disadvantages, for example, power line narrowband carrier communication technologies (such as 421kHz, 270kHz schemes) have low cost and long communication distance, but have the disadvantage of low data communication rate; compared with a power line narrowband carrier communication technology, the micropower wireless communication technology has the advantages that the communication speed is improved, but the micropower wireless communication is easily influenced by obstacles when used in the environments such as buildings with reinforced concrete structures or basements, and the communication quality is unstable; the power line broadband carrier communication technology has the highest data communication rate and strong anti-interference capability, but has the most expensive cost and poorer penetrating capability to an underground cable.
