Spectrum resources are the most precious resources in wireless communication. Due to stratospheric traffic increases, spectrum utilization encounters technical bottlenecks with current wireless technologies. Improving spectrum efficiency has become a problem to be settled urgently. Upgrading communication technology is like upgrading the highway (communication pipeline), in both cases you seek traffic improvement, that is more vehicles (data) within the unit time. To achieve this, the following methods can be used: 1. Expand highways, for example, expand two-lane highways to eight-lane highways. 2. Change the original two-lane highways to elevated highways with the upper and lower decks. In telecommunications, expansion means a new device and network deployment, which requires high investment. If you reduce the car size or improve the top speed of cars, you can ensure that more cars can pass through within a time unit. In the communication field, this method means mobile phone modification to ensure that mobile phones can receive more data. However, the basic architecture of existing mobile phones is fixed and hard to be changed. In addition, once sold, a mobile phone will be used for several years and so won’t conform to 5G standards and won’t contain compliant mobile phone chips. Therefore…
