Industrial Wi-Fi  AP WD-G40A

Brief introduction

WD-G40 series is a new industrial wireless access network equipment developed by Kunshan wondertek Technology Co., LTD. It adopts industrial grade material design to ensure stable communication in harsh industrial environment. Can work in AP or Client overwrite transport mode. High transmission power, high sensitivity, advanced dual-frequency intelligent roaming technology. WD-G40 industrial wireless AP supports IEEE 802.11ac Wave2 technology with a data transmission rate of up to 1267Mbps, meeting the industry's increasing demand for data transmission speed. WD-G40's operating temperature, input power, surge, ESD and seismic design are in line with industry standards and relevant certifications. The DC power supply and PoE power supply can be used for dual redundancy to ensure power supply stability and facilitate onsite deployment. WD-G40 operates in 2.4GHz and 5GHz bands with 2.4g and 5G dual-channel basebands to ensure real-time wireless connectivity; And backward compatibility with existing 802.11a/ b/g/n devices, ensuring that your wireless system deployment can meet future requirements. Products are widely used in railway, mining, airport, subway, coal mine, intelligent storage, industrial automation control, intelligent garage and other sites.
