Problems solved by technology
[0002] At present, wireless transmission systems based on ZIgBee, Bluetooth, and GPRS wireless sensor networks are very limited in terms of transmission distance, transmission reliability, and available spectrum resources, which limits their scope of use in practical applications. It was also proposed However, compared with WCDMA's advantages in network, TD-SCDMA does not rely on the air interface method of GPS, no matter the data throughput in the single carrier of the system is measured. In terms of availability and maturity of technology, it is still much worse

Embodiment Construction
[0012] Below in conjunction with accompanying drawing, content of the invention will be further described:
[0013] Compare the WCDMA4 network technology with the wireless communication technology currently used in wireless sensor networks, as shown in Table 1:
[0014]
[0015] It can be seen from the above table that the WCDMA network has obvious advantages. In electromagnetic spectrum monitoring, real-time and continuous uploading of spectrum data monitored by sensing nodes is often required to achieve dynamic spectrum display. Therefore, a data upload mechanism similar to streaming media services must be designed to ensure reliable transmission of data information and end-to-end Terminal real-time transmission.
[0016] Therefore, the present invention proposes a wireless transmission system and a transmission method based on WCDMA and a sensor network.
[0017] refer to figure 1 and figure 2 As shown, the wireless transmission system based on WCDMA and sensor net...

The invention relates to a wireless transmission system and method based on WCDMA (Wideband Code Division Multiple Access) and a sensor network. The wireless transmission system comprises an embedded type processor chip with a kernel, wherein the embedded type processor chip is connected with an external SDRAM (Synchronous Dynamic Random Access Memory), a Nand-Flash memory and a clock circuit to form a minimum system; and the minimum system is connected with a USB (Universal Serial Bus) interface circuit, a status interface circuit, a WCDMA wireless receiving and transmitting module with an antenna, and a system power supply manager. As the wireless transmission system is combined with the transmission method, a plurality of defects in the prior art can be overcome on the aspects in the data throughput measured inside a system single carrier and an air interface mode independent from a GPS (Global Position System) or the technology availability and maturity of TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), and the long-distance wireless communication of a large quantity of data can be realized.
