Networking requirements put forward by Internet of Things

In the information age, the operation and management of enterprises cannot be separated from the support of the network, but it is not so easy to have a network of their own. Professionals are required, programs need to be written, equipment is purchased, equipment rooms are built, bandwidth is rented, and configuration is done. Commissioning and so on. It takes time and effort to work before and after, and it is necessary to maintain and manage the network after it is completed. If you want to build a wide-area network, then you need to pull a line or open a VPN to further increase the cost and professional requirements of the network.

With the advent of the Internet of Things, communication needs are everywhere and everywhere. Smart meter reading, no-sales, industrial Internet, all walks of life, all things have brought the need for connecting to the Internet. At the same time, in order to access and control the terminals of the Internet of Things in time, the Internet of Things is no longer just satisfied with uploading data in one direction, but also needs to set up a private network to connect the intranets of the enterprise to achieve two-way communication and secure communication. Vehicle networking, logistics tracking, asset positioning, field communications and other Internet of Things scenarios put forward the needs of mobile networking (wireless networking). Emergency communications, emergencies and other scenarios have raised the need for instant fast networking. In summary, in the current Internet of Things era, special networking, mobile networking, real-time rapid networking, and low-cost networking are proposed, which are different from traditional networking requirements.

The emergence of cloud computing provides a convenient way to build a network, but it needs to be used in conjunction with a cloud host. If you leave the cloud host, you will not be able to enjoy the convenience of the cloud network. In addition, the cloud network is actually more complex than traditional networks. Enterprises need to go to the cloud. It is not a simple matter to connect the cloud network to the original network. So, is there a way of networking that does not depend on cloud hosts, but it can be as simple and convenient as cloud computing. That is, how to build a network with on-demand services? We propose an air-to-air broadband based air networking (also called wireless ad hoc network) to meet this networking requirement.

Broadband development of wireless networks

After years of development, wireless cellular communication technology has expanded from 2G, 3G, 4G to 5G in the future, covering a wide range of areas where almost all humans can cover wireless cellular networks. When the IoT device is connected to a cellular network, it is possible to implement an always-on, very reliable network connection condition without re-deployment. More importantly, the cellular network has formed a very well-developed ecosystem. Whether it is infrastructure manufacturers, chip manufacturers, or terminal manufacturers all over the world, including terminal and Sim card's various marketing channels, there are a lot of participants. From the development, verification, production, and marketing of products, a huge industrial chain has been formed, which is why cellular technology has become the most mature, most reliable, and most complete technology.

With the further popularization of mobile phones, notebooks, and wireless routers, and people’s increasing requirements for the speed of the Internet, the development of cellular network technology has been advancing toward the direction of broadband wireless access. Currently, 3G has been fully deployed, technically capable of providing 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 can reach 20Mbps, and can meet the requirements of almost all Internet of Things scenarios for wireless services. The 5G, which is aimed at higher bandwidth, lower latency and greater access density, is also gradually deployed. In step-by-step commercial applications, mobile operators are striving to provide consumers with faster, more convenient, and lower-cost information transmission services.

Air-broadband-based aerial networking solution

Starting from the demand of the Internet of Things, we propose an air networking solution based on wireless broadband. Taking the typical IoT scenario as an example, the air networking solution is adopted. It no longer needs to pull optical fibers, buy equipment, lease bandwidth, configure, etc. And so on, as long as a few Internet of Things cards (here, the sim card for the Internet of Things) are installed on the server side and the Internet of Things terminal, after setting up in the background, an IoT private network can be quickly established nationwide to achieve IoT terminal data collection, control management or mobile monitoring.

First, build a third-party VPDN connection platform and connect to the operator's wireless cellular network through a virtual private line. Then the VPDN card (that is, the directional sim card for the IoT) is opened at the operator. The VPDN card has a fixed private IP address, and the IP address is fixed during the entire life cycle of the card. At the same time, the traffic of the VPDN card will be transmitted to the VPDN connection platform via the virtual private line. The VPDN platform establishes connection and forwarding rules based on the networking requirements of the Internet of Things and interconnects relevant VPDN cards to form an Internet of Things special network composed of VPDN cards. Terminals or servers within 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, this physical connection network is isolated from the external network to ensure communication security, and the protection card traffic is used effectively. According to the needs of the scene, Internet portals can also be opened to allow Internet of Things terminals to access resources on the Internet.

The airborne network based on wireless broadband can use the high-quality 3G or 4G wireless network in China to implement wide-area networking across the country. Inter-operator communication between the Internet of Things card and the Internet of Things card can be achieved. 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, and can be plug-and-play, eliminating network maintenance. The network can be closed to ensure security, or it can be connected to the intranet or the Internet according to business needs.
