The invention provides a universal information handling method and a platform suitable for wireless simulation equipment in all frequency ranges. The universal information handling method suitable for wireless simulation equipment in all frequency ranges comprises an upper layer software, an agreement layer, a driving layer and digital signal processor (DSP) audio signal process. A VxWorks operation system is utilized on the software, a bottom driving procedure, an operation system procedure and an upper layer application procedure are respectively developed, and the same function functional module is utilized on the same functional function. The same hardware module is utilized to set up a common platform on a hardware framework which is centered by an advanced risk machines (ARM) embedded type microprocessor, and the software is emphasized to be replaced by the hardware. Simulation is conducted on functions and operation realities of various wireless communication equipments in practical application, and system updating can be conveniently conducted on the wireless simulation equipments which are connected in the network on terminal equipment through Ethernet technology. Meanwhile, simulation on various wireless communication equipments can be achieved just by changing the upper layer application software. The universal information handling method and the platform suitable for wireless simulation equipment in all frequency ranges has the advantages of being reasonable in design, effective in access and reliable in working.
