Internet of things industrial UART serial port to WiFi to wired network port to Ethernet Gateway WiFi module selection

With the development of Internet of things , The original physical layer of direct communication between the two machines through hardware to the data link layer of communication through hardware address and LAN has been far from meeting the needs of modern people's life and all walks of life production . Gradually combine high performance , High quality network layer and application layer . Realize intelligent terminal data collection , The data transfer , Data upload and wireless Internet ,WiFi Remote control and other functions . In the Internet of things market , From cost , Power waste , In terms of volume , Wireless Internet of things WiFi Module transmission is still through serial port WiFi Module based .
A serial port WiFi Module is based on UART Interface embedded module , It conforms to WiFi Wireless network standards , Embedded in IEEE802.11 Protocol stack and TCP/IP Protocol stack , It can realize user serial port or TTL Conversion of level data to wireless network . Serial port type WiFi The working mode of the module is transmission type and command type .
Now I want to talk about the multi-threaded and multi-processing routing serial port WiFi modular . With the real-time monitoring of field data , Remote control , Data upload , video transmission , The demand for audio transmission increases . Routing serial port WiFi Modules are gradually applied to all walks of life . The core CPU belt Linux System , It can process multiple threads and complex instructions at the same time ,. There are multiple serial UART Interface , When transmitting instructions, multiple instructions are issued at the same time , And respond quickly and deal with .
With core CPU with Linux Routing serial port of system multithreaded processor WiFi modular RMS7688A, Is compatible 802.11b/g/n Wireless AP Solution , Integrate 802.11n MAC/BB/PA/LAN, The bandwidth is relatively large , Can operate complex instructions at the same time . Have 3 Serial port can connect with multiple servers at the same time ,3 Serial port can quickly monitor the temperature in the same environment at the same time , Speed , Light control and other data command transmission . Improve efficiency to a great extent , cost reduction .RMS7688A Serial port to WiFi Module support AP/AP client / Router / Relay mode , stay IOT Widely used in . Such as ： Industrial control , Remote monitoring , Smart meter reading ,WiFi To serial port ,WiFi turn 4G,4G Wire transfer , Serial port to network port ,4G Switch network port , Wireless routing switch , Serial server , Serial port to Ethernet ,USB Can connect USB The camera transmits images , Can connect U Disk for data sharing .UART Bluetooth module can be connected ,zigbee modular ,ZWave modular ,Lora modular ,2.4G modular ,433 The module is made into a Bluetooth gateway ,Zigbee Gateway and so on .
