First, understand WLAN and WiFi literally. The full name of WLAN: Wireless Local Area Networks, translated as: wireless local area network, refers to the application of wireless communication technology to interconnect computer equipment, constitute a network system that can communicate with each other and achieve resource sharing. WiFi is a technology that allows electronic devices to connect to a wireless local area network (WLAN). Translating adult messages is probably: WLAN is a big network, and WiFi is a technology under this big network.
From the perspective of the coverage of the two, WiFi coverage is smaller, and the coverage is generally only 90m. Like Bluetooth, the distance from the transmitter will not be able to receive the network. When we use WiFi, the farther the WiFi signal is from the router, the weaker it is because the WiFi coverage is smaller. The WLAN covers a wide range of coverage and can reach a range of 5km. This range is not comparable to WiFi.
Finally, come to see the relationship between the two. WLAN As a network, WiFi is a standard. WLAN refers to this type of wireless LAN, and the establishment of wireless LAN will use many different data transmission standards, WiFi is one of the standards. At the same time, WLAN is a kind of mobile phone function. WiFi is a kind of authentication method. With a WiFi-certified mobile phone, it has WiFi standard WLAN function.
Above, does the distinction between WLAN and WiFi have come?

Smart TV/box information can focus on smart TV information network sofa butler (http://), China's influential TV box and smart TV website, providing information, communication, TV boxes, smart TVs, smart TV software, etc. Answering questions.Incremental encoders provide speed, direction and relative position feedback by generating a stream of binary pulses proportional to the rotation of a motor or driven shaft. Lander offers both optical and magnetic incremental encoders in 4 mounting options: shafted with coupling, hollow-shaft, hub-shaft or bearingless. Single channel incremental encoders can measure speed which dual channel or quadrature encoders (AB) can interpret direction based on the phase relationship between the 2 channels. Indexed quadrature encoders (ABZ) are also available for homing location are startup.
