Vanch RFID System

Previously, MORLAB has completed the testing and certification of several RFID products. Let's take a look at the RF test points of the next UHF band RFID. At present, the UHF RFID operating frequency band used in Europe is between 865MHz and 868MHz, and the power does not exceed 2W. According to the R&TTE directive, the radio frequency test in the CE certification needs to refer to the harmonized standard EN302 208-2 for testing. Usually, a complete RFID system has two parts: RFID reader (Interrogators) and RFID electronic tags (Tags), and the tests of the two are also different. The following is an introduction to the test of a scanner. The modulation method of this product is ASK, the power is 30±3dBm, and the effective working frequency points are: 865.7MHz, 866.3MHz, 866.9MHz, 867.5MHz. The spectrum diagram under the working condition of the product After a comprehensive evaluation of the customer's product by MORLAB engineers, the product is classified as a handheld

Speaking of RFID , in fact, it is widely used, and it is even used every day, such as our second-generation ID card. Mr. Xuetang said that the application of RFID in daily life is good~+RFID (Radio+Frequency+Identification, radio frequency identification) is a wireless communication technology that can automatically identify target objects and obtain related data through radio frequency signals. It is the Internet of Things One of the commonly used short-range wireless communication technologies. +RFID electronic tags have a complete set of modulators, encoders, memories, controllers and antennas, according to application requirements, you can choose the built-in battery to work together. +Compared with ordinary bar codes, RFID technology has the advantages of waterproof, anti-magnetic, high temperature resistance, long service life, long reading distance, encryption of label data, and larger storage capacity that ordinary bar codes do not have. +The electronic tag can realize the read

The radio signal recognizes a specific target and reads and writes related data, without the need to establish mechanical or optical contact between the recognition system and the specific target. The radio signal is an electromagnetic field tuned to a radio frequency to transmit data from the tag attached to the item to automatically identify and track the item. Some tags can obtain energy from the electromagnetic field emitted by the recognizer during identification, and do not require a battery; some tags have their own power source and can actively emit radio waves (electromagnetic fields adjusted to radio frequencies). The label contains information stored electronically and can be identified within a few meters. Unlike the barcode, the radio frequency tag does not need to be in the line of sight of the recognizer, and can also be embedded in the tracked object. Expansion information: Many industries have used radio frequency identification technology. By attaching the label to a
