Runsun Technology Runsuntech introduced the fastest Wi-Fi DTU Module to industry

2016/3/24 Beijing


In the field of IOT applications, more and more embedded electronic devices use Wi-Fi technology to connect to the local server, or access the Internet, to achieve data upload/download, remote control, cloud computing and other functions. Most of these embedded devices have no rich system resources or powerful operating system, in particular, network protocols. General Wi-Fi network card (module) can only support Windows, Linux and Android such OS systems, which do not meet the application requirements of small embedded systems. The existing UART interface embedded Wi-Fi module can only provide throughput rate below 2Mbps, which is far below the high bandwidth Wi-Fi protocol can provide.

       The RSW126 high speed Wi-Fi DTU module developed by Beijing Runsun Technology Co., Ltd (Runsuntech here after), can provide high capability of data transmission for small embedded systems. The table below is comparison between the RSW126 module and other modules.

According to the table above, RSW126 is the best choice for small embedded systems such as remote control car or UAV, which have requirement of large amount of data transmission as audio/video, and quick launch at the same time.

RSW126 throughput testing system introduction


The module host system RSWV100 evaluation board (EVB) integrated with RSW100 secondary development platform is also developed by Beijing Runsun Technology Co., Ltd. The main technical features of RSWV100 are as follows: 32bit CPU with 160MHz, 448KB RAM,  FreeRTOS.

What the key know technology for RSW126 to achieve such a high throughput rate? Let`s analyze the factors and advantages of RSW126 that affect the throughput.


RSW126 module uses high-speed SPI interface to communicate with host system, the maximum bus frequency is 50MHz, and network throughput is up to 15Mbps. The module integrates all network protocols, supports IEEE802.11b/g/n standard, supports 10 TCP connections, 6 UDP connections, and supports smart config provisioning method. The module provides a cross-platform host driver software, which is programmed with C language (ANSI C89), and cost very little resources (code RAM<6KB data RAM<4KB), very easy porting to all kinds of embedded host platform.


Customers of Runsun technology have tested all the existing Wi-Fi modules that support high speed transmission. The test result proved that RSW126 has advantages of cost less host resources consumption, lower power consumption, flexible configuration, and 2 times higher throughput rate than other modules.

Although the RSW126 can reach 15Mbpsin the laboratory, what occasions can it be used? How can it affect the smart product market?


The RSW126 module can provide 15Mbps throughput rate without increasing load of host machine, which is very suitable for wireless transmission of audiovideo and a large amount of data. In addition the modules can work very quickly after power-up. The application instances are as following:
