WiFi module: WiFi is a wireless fidelity technology based on IEEE 802. 1 1 standard, which allows electronic devices to connect to a wireless local area network (WLAN), usually using 2.4G and 5G radio frequency bands. WiFi is suitable for occasions with large amount of data, short distance and relatively poor stability, mainly used for home and business applications! SKYLAB began to develop WiFi module in 2009. After 10 years' efforts, the WiFi software and hardware research and development team finally exported a number of high-performance WiFi modules for the Internet of Things market, such as USB interface WiFi module for video transmission, IoT WiFi module for data transmission, AP/Router WiFi module for router scheme, and high-power WiFi module for remote image transmission of drones. The application fields cover Internet of Things smart homes, smart factories, intelligent transportation and drones.

4G module: 4G module is the collective name of LTE, TD-LTE, FDD-LTE and other network standards. It has the characteristics of fast communication speed, wide network spectrum and flexible communication. The 4G module refers to the products whose hardware is loaded into the specified frequency band, whose software supports the standard LTE protocol, and whose software and hardware are highly integrated and modularized. The hardware integrates RF and baseband on a PCB board to complete the functions of wireless receiving, transmitting and baseband signal processing. The software supports voice dialing, SMS sending and receiving, dial-up networking and other functions.
