Description

Technical field [0001] The present invention belongs to the technical field of wireless communication. More specifically, the present invention relates to a Zigbee-based remote wireless transceiving full-function device and a transceiving method thereof. Background technique [0002] For home control, industrial automation and other applications, the commonly used wireless communication solutions now include Wi-Fi, UWB, IrDA, NFC and ZigBee technologies. The transmission rate of Wi-Fi is fast, up to 100 meters, but the cost is high and power consumption is high; UWB has a high transmission rate, low transmission power, but short communication distance; Bluetooth has a high transmission rate, but the transmission range is small, and the node power consumption is high ; IrDA has a short transmission distance, and it can only connect two devices at the same time, so flexible networking is not possible; NFC has a short transmission distance. The ZigBee technology has the characteris...

Problems solved by technology

[0003] There are more and more types of Zigbee chips, such as the widely used CC2530, and MC13192, AT86RF230, MRF24J40, and these chips have a common feature, that is, the chip itself has an MCU, because the chip itself is responsible for both signal transmission and reception. Responsible for signal processing, which leads to limited processing capacity of the MCU, high power consumption, and poor function expansion capabilities

Secondly, when using these chips for wireless communication research, since the transmitting power of the chip itself is very small, and its receiving sensitivity is also fixed within a certain range, this limits the communication distance of the wireless sensor network, and the actual transmission The distance is only a few hundred meters
