Based on outdoor satellite positioning technology, it cannot be used indoors normally. WENSHING released the RTLS UWB precise positioning module (model:UWB-22DBAB) in April 2021. It is solve the problem of unable to receive GPS signals indoors and unable to locate. Two-way sensing to ensure high accuracy, the error is within 10CM; high power, low power consumption; strong penetrating power; large capacity and fast transmission speed. Wenxing electronic antenna design uses an innovative PCB high-frequency antenna built in to the module, users can quickly import products, the distance is more than 800M (open area) and ultra small size.The number of plant deployments does not need to be large, minimization of costand maximization of utility.
