Advantages: It has a wide range of applications and is a global operating frequency band. The developed products have global universality, and various wireless products can use this frequency band, widely used in indoor environments such as personal wearable devices and wireless broadband routers. The overall bandwidth of a high bandwidth home wireless router is superior to other ISM frequency bands, which improves the overall data transmission rate, allows system coexistence, allows bidirectional transmission, and has strong anti-interference ability and long transmission distance (within the range of short distance wireless technology). The antenna size of a 2.4GHz radio with low power consumption is relatively small, and the product size is also smaller, making the chip more concentrated and reducing power consumption. Due to the advantages of 2.4GHz wireless technology, various manufacturers are continuously introducing new technologies, which has also led to the rapid development of this technology. The technical standard ZigBee/IEEE 802.15.4ZigBee technology is an emerging short distance wireless communication technology, mainly aimed at the application field of low rate wireless personal area network (LRWPAN). Its typical features are close range, low power consumption, low cost, and low transmission rate, mainly suitable for automatic control and remote control fields, The purpose is to meet the wireless networking and control needs of small and inexpensive devices [2]. The 2.4GHz frequency band is the global common frequency band, while 868MHz and 915MHz are the ISM frequency bands used in the United States and Europe. The introduction of these two frequency bands avoids mutual interference from various wireless communication devices near 2.4GHz. At the same time, Zig Bee also has some shortcomings such as small transmission range, low data transmission rate, and difficult to determine delay. Wi Fi (Wireless Fidelity), also known as IEEE 802.11 protocol, is a short-range wireless transmission technology that can support wireless signals for internet access within a range of hundreds of feet. The first version of WiFi was published in 1997, which defined the media access control layer (MAC layer) and physical layer. It specifies the basic network structure and transmission medium of wireless local area networks, and standardizes the characteristics of the physical layer and medium access layer (MAC). The physical layer adopts infrared, DSSS (direct sequence spread spectrum) or FSSS (frequency modulation spread spectrum) technology. In 1999, IEEE 802.11a and IEEE 802.11g standards were added. Its transmission rate can reach up to 54 Mb/s. It can widely support services such as data, image, voice, and multimedia. Wi Fi, also known as wireless local area network, operates in the 2.4GHz frequency band and is used as a wireless connection technology in school, commercial and other office areas. The transmission rate can reach 54Mbit/s, and the working distance can reach up to 100m. It adopts direct sequence spread spectrum (DSSS) method. The main driving factor for adopting Wi Fi is data throughput, which is generally used to connect computers and wireless devices to local LANs or directly to the Internet. Due to the use of radio frequency technology in Wi Fi, data is transmitted and received through air, and wireless waves are used to transmit data signals, making it more susceptible to external interference. Data packets can be detected or received by the outside world during transmission, and information security is a hidden danger. Although data can be encrypted and transmitted, there is still a possibility of being hacked when there are enough data packets
