Abstract: An Internet of Things (IOT), a communication method, a bridge device and an access device for the IOT are disclosed. The method is applied to the bridge device for the IOT, and includes: receiving, by the bridge device, data information carrying a specified identification sent from an IOT access device; searching for, by the bridge device, a power consumption device in the IOT corresponding to the specified identification; determining, by the bridge device, whether the power consumption device and the IOT access device support the same communication mode and communication protocol; converting, by the bridge device, the data information into data information which is identifiable to the power consumption device, in the case that it is determined that the power consumption device and the IOT access device support different communication modes and communication protocols; and sending, by the bridge device, the converted data information to the power consumption device.

Abstract: A compatible communication device includes an analog front end, a baseband communication unit, a wireless radio frequency module, a power line communication front end and a control unit. The analog front end is connected to each of the baseband communication unit, the wireless radio frequency module and the power line communication front end. The baseband communication unit transmits baseband signals. The analog front end performs signal conversion between digital domain and analog domain. The control unit selects, based on the channel quality for signal transmission, one or two of the power line communication front end and the wireless radio frequency module for communication. The signal receiving or transmission is performed through a power line if the power line communication front end is selected for communication. Or, the signal receiving or transmission is performed through a wireless channel if the wireless radio frequency module is selected for communication.
