What is the effective range of uhf rfid reader to receive radio waves?
In fact, this principle is the same as the radio we listen to. The radio frequency tag and uhf rfid reader must also be modulated to the same frequency to work. LF, HF, UHF correspond to radio frequencies of different frequencies. Generally speaking, LF stands for low frequency radio frequency, around 125KHz, HF stands for high frequency radio frequency, around 13.54MHz, UHF stands for ultra high frequency radio frequency, in the range of 850 to 910MHz.
Why read and use different frequencies?
There are 4 kinds of frequency bands in operation, because in different fields, it is necessary to choose different ones to be used in different fields, so to use it correctly, we must first select the appropriate frequency.
What kind of uhf rfid reader do I need?
The uhf rfid reader is just like the label, so it is necessary to determine the type and quantity of use by studying the supply method. For example, to manage the inventory of incoming and outgoing warehouses, uhf rfid reader can be installed on the cargo door of the terminal. If the requirement is to manage the products sent to a specific customer, the uhf rfid reader should be installed not only on the door, but also on the truck. If the requirement is to control retail shelves, fixed or handheld devices can be used to facilitate automatic outbound recording and counting.
