This time there are a lot of customers consulting wireless barcode scanner which kinds? What does the wireless scanner rely on to communicate? What’s the difference between a bluetooth scanner and a wireless scanner?
Wireless scanner also known as cordless scanner, is a different from the wired scanner bar code identification reader. Generally through Bluetooth, WiFi and other data transmission, can not be limited by the length of the data cable transmission data, easy to use.
For example, just like the mouse and the wireless mouse, the advantage of the wireless mouse is not constrained by the data cable, and it is more convenient to use. Similarly, the wireless scanner scanner, like the wireless mouse, has a wireless receiver. It’s called a donggle, or a Bluetooth receiver. (This isn’t necessarily true, though, because it’s 433MHz or 2.4GHz, which is more common.)
First of all, the classification of barcode scanners wireless can be distinguished from the different wireless communication technologies used.
The mainstream wireless communication methods used by the wireless scanning scanner include Bluetooth, 433MHz, 2.4GHz
At present, 433MHz is the most common wireless communication mode. The advantage of this frequency band is that the wireless communication distance is longer than 2.4GHz, because the frequency is lower than 2.4GHz and the wavelength is longer, which is more conducive to avoiding obstacles and the farther the transmission distance is. Usually,433MHz in the open space, can reach 100 meters -400 meters of transmission distance, and in the room, its communication distance can reach 20 meters ~60 meters,20 meters ~30 meters of performance is very enough. 2.4GHz wireless scanning scanner, the wall penetration performance is not good, generally one wall, and the distance should not be too far, strong anti-interference ability, 2.4GHz than 433MHz transmission rate, more suitable for mobile environment.
So, the most commonly used wireless frequency is 2.4GHz. This frequency is the most widely used method of NFC, and Bluetooth is actually a 2.4GHz frequency, but Bluetooth is a special case of 2.4GHz. The 2.4GHz wireless scanner scanner usually communicates within 10 meters, the same as Bluetooth.
Bluetooth wireless communication is actually a standardized 2.4GHz wireless communication mode. In general, laptops and mobile phones are equipped with Bluetooth receivers. That is to say, Bluetooth does not need additional wireless receiver, and 433MHz and 2.4GHz have wireless receiver (each wireless communication standard is slightly different, not necessarily universal, Bluetooth is all devices are universal communication protocol).
Finally, talk about WiFi scanner, in fact, there are very few in the market, generally enterprise customized use of the program. The name magic, is connected to WiFi through the scanning scanner for use. Restricted by the appearance of the scanning scanner, the connection to WIFI is not convenient (how to enter SSID and password without keys? It can be connected via peer-to-peer WiFi, but it’s still inconvenient).
The barcode scanning scanner distributed by MINJCODE can have a wireless communication distance of up to 200 meters, can penetrate walls, durable, outstanding scanning ability, and can read the damaged stain barcode and high density barcode.
