With the development of 5G and its deepening integration with the real economy, some practical problems have surfaced. Among them, cost and performance have become the two most prominent problems: first, the contradiction between the high cost of 5G terminal chips and modules to the terminal and the application of 5G in vertical industries; second, the actual demand for many application scenarios is medium speed requirements , the performance requirements are medium, the power consumption requirements are medium, and the requirements are higher than NB-IoT and lower than 5G.

Regarding PCB design, many electronic engineers are very skilled. As a technical developer, the PCB design process is not smooth sailing. For the "siege lions" of different levels (ranks), sometimes they are happy and sometimes sad.

Recently, China Mobile announced the launch of a 5G convenient nucleic acid collection station, providing a standardized solution for 5G convenient nucleic acid collection stations for 32 cities in 17 provinces (autonomous regions and municipalities). Nine provinces (autonomous regions and municipalities) including Jiangxi, Jiangsu, and Zhejiang have landed.

A transistor is a solid-state semiconductor device (including diodes, triodes, field effect transistors, thyristors, etc.), which has various functions such as detection, rectification, amplification, switching, voltage regulation and signal modulation.

There are many similarities between the two, such as: 2.4G frequency band. The wireless module power consumption is very low. They can all be located by the base station. Positioning can be assisted by third parties, because there are many similarities, there is hesitation when choosing a plan, of course, the final choice or from user scenarios, but from the perspective of technology development and reliability, Bluetooth positioning is the development of RFID direction, so let's do it together.

As one of the important infrastructures of the digital industry, the Internet of Things has ushered in a golden period of development. Through the collection, analysis, and output of data, the Internet of Things communication technology has deepened from shallow interconnected tools and products to become the infrastructure and key elements to reshape the production organization, and is profoundly changing the traditional industrial form and people's lives. way, the era of ubiquitous IoT has arrived.

As we all know, the technologies used to introduce 5G and WiFi 6E wireless networks are revolutionary in terms of spectrum usage, components, etc. In order to meet the 5G key performance indicators, iterative improvements of the technology must be realized on the previous cellular infrastructure.

​ Although 5G (fifth generation mobile communication technology) has entered the market, in fact, except for a few industries, the application of 5G technology in the service industry, industry and other fields will not spread quickly, so it will still be a long time in the future. The world of 4G and NB-IoT.

Under the background that the human world attaches great importance to green and low-carbon development, "green" has become a new keyword in the telecommunications industry, and "5G changes society" has also been endowed with richer connotations.
