Zigbee wireless communication device

Abstract

The invention discloses a Zigbee wireless communication device, which comprises a CC2530 single chip, an antenna, a crystal oscillator with the frequency of 32MHz and a terminal, wherein in the CC2530 single chip, an RFN end and an RFP end are connected with the antenna; a P2.3 end and a P2.4 end are connected with the crystal oscillator with the frequency of 32MHz; and a P0.2 end and a P0.3 end are connected with the terminal. The Zigbee wireless communication device can overcome the defects of short communication distance, low communication speed, low penetrating power and the like in the prior art so as to achieve the advantages of long communication distance, high communication speed and high penetrating power.

Description

technical field [0001] The present invention relates to communication technology, in particular to a Zigbee wireless communication device. Background technique [0002] Zigbee is synonymous with the IEEE802.15.4 protocol, and the technology specified in this protocol is a short-distance, low-power wireless communication technology. [0003] Zigbee is a wireless data transmission network platform composed of up to 65,000 wireless data transmission modules, which is very similar to the existing mobile communication CDMA network or GSM network. Each Zigbee network data transmission module is similar to a base station of the mobile network. They can communicate with each other within the entire network; the distance between each network node can range from the standard 75 meters to hundreds of meters after expansion, or even several kilometers; in addition, the entire Zigbee network can not only be expanded "infinitely" Open, but also can be connected with various other existin...

AI Technical Summary

Problems solved by technology

[0006] ⑴Short communication distance: Zigbee is based on IEEE802.15.4 network technology, and its low power consumption makes its transmission distance within 100 meters. Even if a power amplifier chip is added, the distance cannot be greatly extended

Only suitable for short-distance communication and data transmission;

[0007] ⑵Slow communication rate: Zigbee works in the 2.4GHz frequency band, and the higher frequency causes the communication rate between Zigbee wireless communication devices to be relatively low, and the peak value will be 250Kbps;

[0008] (3) Weak penetrating ability: The higher frequency band of Zigbee makes the wavelength of electromagnetic waves generated by Zigbee communication shorter, which is not conducive to penetrating thicker objects, such as floors, reinforced concrete, etc.
