Second, the technology is not yet mature. Big data analysis is still required after sensors collect data from the edge. It is not yet possible to integrate and connect data collection and analysis across different industries and fields. The high-value of data will only be released once analysis is integrated deeply with industry applications. Third, security issues. Compared with the hard secure protection of mobile phones, IoT sensor structure is relatively simple, making it easily used as a springboard for distributed technology attacks. IoT must solve these development problems of cost, technology, and security before it can become widely used in the industry. Mobile communication networks The transition from 5G to 6G is still in its early stages. The ideal Metaverse requires at least 6G or even more powerful networks. 6G network communication should be fully implemented by 2030. 6G can go far beyond the powers of 5G to support microsecond or even sub- microsecond delay communication, positioning accuracy of 10 centimeters indoors and 1 meter indoors, and the "Internet of Everything" on a global scale. Intuitively, in the 6G era, when downloading 300 movies will take just the blink of an eye, then it will also be possible to achieve almost zero-latency shuttle interactions in the Metaverse. The development of 6G networks is hugely reliant on breakthroughs in its four main technologies: terahertz technology, air-space-sea-terrestrial integration, deterministic networks, and AI-based air interfaces. Because the frequency band of terahertz technology is 1-4 orders of magnitude greater than existing microwave communication, it can carry more data, easily overcome bandwidth limitations, and meet the communication requirements of large data transmission rates.
