With the continuous development of information technology, the use of scanning code guns in enterprises, factories, logistics and other scenes is becoming more and more common. The scanning code gun can be divided into two types: a wired scanning code gun and a wireless scanning code gun. The wired scanning code gun, as the name implies, transmits data through a data line and a computer or a POS machine. We all know that wired scan code guns are relatively inconvenient to use because they are affected by the transmission data lines.
The wireless scan code gun, also known as the cordless scan code gun, can transmit data without being limited by the length of the data cable, and is convenient to use. If the wireless scan code gun is classified from the network connection, there are two ways of directly connecting to the wireless Wi-Fi and configuring the 4G full Netcom.
What is the difference between the wireless scan code gun and the two network connections?
Adapt to different scenes
4G full Netcom: 4G full Netcom connection is suitable for courier and other mobile scanning scenes.
Wireless Wi-Fi: The wireless scan code gun is suitable for such situations as enterprise warehousing, production workshops, hospitals, pharmacies, etc. The scanning code gun usage scene is relatively fixed, which is convenient for wireless coverage.
Wireless signal stability is different
4G full Netcom: 4G full Netcom scan code gun signal stability and transmission speed are mainly related to the base station built by the operator. The enterprise factory area is generally remote, and the mobile signal is relatively poor and unstable due to the actual situation of the production workshop environment.
Wireless Wi-Fi: The wireless scanner has a stable signal and good roaming effect in areas that have been covered by wireless.
Different data transmission security
4G full Netcom: 4G full Netcom scan code gun data transmission is not safe. The scanning code gun in the factory is to transmit the data to the software platform ERP in real time. If it is transmitted through 4G, the enterprise logistics or business software will be exposed to the public network, and the data transmission will be easy to leak.
Wireless Wi-Fi: Wireless scan code gun data transmission is relatively safe. The wireless scan code gun is built by professional enterprise-level wireless. The data transmission will not be exposed to the public network. At the same time, the enterprise-level wireless construction controller has its own firewall, which can effectively isolate bad attacks and protect the wireless security and stability.
Different derivative effects
4G full Netcom: 4G full Netcom scan code gun is mainly used for daily scan code, there is no additional additional effect for the enterprise.
Wireless Wi-Fi: The wireless scan code gun has many additional functions. When the production workshop uses the wireless scan code gun, it can do asset positioning through Wi-Fi, and have real-time understanding and supervision of the enterprise assets. At the same time, it can understand the use of the code sweeping gun in the production workshop in the background and facilitate management.
Wireless scan code gun docking scenario (taking factory and warehouse as an example):
We all know that the general building structure is divided into: brick-wood structure, brick-concrete structure, reinforced concrete structure and steel structure. The structure of the wireless scan code gun is regular and the height is generally 5m-20m. The interior mainly stacks shelves and goods. Wireless coverage considerations: area covered, height of building, amount of concurrent data, placement of internal goods. The terminal has a small amount of concurrency. The main terminal types are scanning code guns and PDAs, which are used for collecting cargo information. The bandwidth of each scanner is not more than 50Kbps.

Of course, the way APs are arranged varies depending on the height of the building.
