We compared the commonly used communication methods in the market and found as following:

	Wi-Fine	RF	Wifi	RS485
Definition	a new type of RF communication -- WiFine. Wireless Free Intelligent Network	Radio frequency is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz.	Wifi communication is a wireless local area network communication technology.	RS-485, also known as TIA-485 or EIA-485, is a standard, originally introduced in 1983, defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced, and multipoint systems are supported
advantage	reading data at any time, no latency, low-power consumption made by meter and Stable signal.	commonly used wireless communications, is favored by everyone for its strong penetrability	Using Ethernet communication protocol, the communication distance is usually tens of meters. Because of globally unified standards, any Wi-Fi standard equipment will operate correctly anywhere in the world.	The communication signal is relatively stable,
disadvantage	/		The transmission rate is low, which is only suitable for personal terminals and small-scale network applications.	it can only communicate with a single host. Generally it has 32 network nodes, and maximum 256. In addition, wiring is required. For buildings that have been renovated, installation is almost impossible.
