In the information age, enterprise operation management is inseparable from network support, but it is not so easy to have a network of its own. Professionals need to write solutions, buy equipment, build computer rooms, rent bandwidth, configure, and do Commissioning and so on. It takes time and effort before and after, and it is necessary to maintain and manage the network after it is built. If you want to build a wide area network, you need to pull a dedicated line or open a VPN, and further increase the requirements for network cost and professionalism. With the advent of the Internet of Things era, communication needs are everywhere, and there is no time. Smart meter reading, no sales, industrial Internet, all walks of life, everything has the need to connect to the Internet. At the same time, in order to timely access and control IoT terminals, the Internet of Things is no longer only satisfied with one-way uploading of data, but also needs to set up a private network to connect to the enterprise intranet to achieve two-way communication and secure communication. Internet of Things, logistics tracking, asset positioning, field communication and other Internet of Things scenarios have raised the need for mobile networking (wireless networking). Emergency communication, emergencies and other scenarios raise the need for instant and rapid networking. To sum up, in the current Internet of Things era, the Internet of Things, mobile networking, instant fast networking, and low-cost networking are different from traditional networking requirements. The emergence of cloud computing provides a convenient way to build a network to a certain extent, but it needs to be used together with the cloud host. Without the cloud host, the cloud network is not convenient. In addition, the cloud network is actually more complicated than the traditional network. If enterprises want to go to the cloud, it is not easy for the cloud network to connect to the original network. So is there a networking method that can be independent of cloud hosts, and can be as simple and convenient as cloud computing, that is, ready-to-use, on-demand service networking? We propose a wireless broadband-based air networking (also known as wireless ad hoc network) to meet this networking needs. After years of development, wireless cellular communication technology from 2G, 3G, 4G to the future of 5G, coverage is very wide, almost everywhere humans can cover the wireless cellular network. When the IoT device accesses the cellular network, it can achieve always-on, very reliable network connection conditions without redeployment. More importantly, cellular networks have formed a very sophisticated ecosystem. Whether it is infrastructure vendors, chip vendors, or global terminal vendors, including terminal and Sim card marketing channels, there are many participants. From product development and verification to production and listing, a huge industrial chain has been formed, which is why cellular technology has become the most mature, reliable and complete technology. With the further popularization of mobile phones, notebooks, wireless routers and other devices and the increasing demand for Internet speed, the development of cellular network technology has been advancing toward the direction of wireless access broadband. Currently, 3G is fully deployed and can provide 10-20Mbps download speed or 2-5Mbps upload speed. Faster 4G has also been widely deployed. 4G systems can be downloaded at 100Mbps, uploading speeds up to 20Mbps, and meeting the requirements of wireless services in almost all IoT scenarios. 5G for higher bandwidth, lower latency, and greater access density is also being deployed. In the gradual commercialization, mobile operators are striving to provide consumers with faster, more convenient and lower cost information transmission services. Starting from the demand of the Internet of Things, we propose an air networking solution based on wireless broadband. Taking a typical IoT scenario as an example, we adopt an air networking solution, eliminating the need to pull optical fibers, buy equipment, rent bandwidth, and configure. Wait, as long as a few IoT cards (here is the sim card for the Internet of Things) installed on the server side and the Internet of Things terminal, through the background setting, you can quickly build an IoT private network nationwide, to achieve Data collection, control management or mobile monitoring of IoT terminals. The specific implementation of the background of the air networking solution is shown in the figure below. First, build a third-party VPDN connection platform and connect to the carrier's wireless cellular network through a virtual private line. Then the VPDN card (ie, the directional SIM card for the Internet of Things) is opened at the operator. The VPDN card has a fixed private IP address, which is fixed throughout the life of the card. At the same time, the traffic of the VPDN card will be directed to the VPDN connection platform through the virtual private line. The VPDN platform formulates connection and forwarding rules according to the networking requirements of the Internet of Things, and interconnects the related VPDN cards to form an Internet of Things network composed of VPDN cards. The terminals or servers in the private network can access each other. The Internet of Things terminal can upload data to the server, and the server can also manage or receive data of the Internet of Things terminal according to the fixed IP address of the VPDN card. At this time, the Internet of Things is isolated from the external network to ensure communication security, and the traffic of the protection card is effectively used. Internet exports can also be opened according to the needs of the scene, so that IoT terminals can access resources on the Internet. The wireless broadband-based air networking can use the domestic high-quality 3G or 4G wireless network to carry out wide-area networking across the country, and realize intercommunication between the IoT card and the IoT card across operators. It is simple and fast to deploy, does not require construction wiring, and does not require installation and configuration. It can be deployed at any time according to requirements, plug and play, and free of network maintenance. The network can be closed to ensure security, and the intranet or the Internet can be connected according to business needs.
