Tag identification layer of Electronic Product Code (EPC) Gen 2 lays down the method by which the readers can receive the identifiers from the tags. EPC Gen 2 (second generation) RFID (Radio Frequency Identification) network has two main components, tags and readers. RFID tags are affixed on objects with EPC encoded on them for identification. EPC helps to check identities of objects like inventory, assets and people, and track them. Readers are the intelligent part of the system that tracks the tags. The tag identification layer addresses the multiple access problem of getting messages from unknown number of tags.Working PrincipleIn ... Read More

Backscatter is a method that uses an incident radio-frequency (RF) signal to transmit data without a battery or power source. It employs passive reflection and modulation of the incoming RF signal, and converts it into tens or hundreds of microwatts of electricity, that can be encoded for data communications.It differs from other wireless communications since the communication is half duplex in nature, i.e. both the sender and receiver cannot transmit simultaneously. The mains advantage of backscattering is that it’s low energy requirements and low complexity of deployment.Architecture of backscatter communicationsA basic backscatter communication system has two main components: tags, and ...

Electronic Product Code (EPC) is a universal identifier that aims to render a unique identity to every possible physical object of the world. EPCs are mostly encoded on RFID (Radio Frequency Identification) tags that are used to check identities of objects like inventory, assets and people, and track them.EPC is the 96–bit number associated with an RFID tag for identifying a particular tag amongst other tags. It distinguishes two identical products, and also provide the product’s manufacture date, origin or batch number.The EPC structure is laid down by EPCglobal Tag Data Standard, an open standard freely defined by EPCglobal Inc.EPC ...

In a computer system, a port provides an interface to connect a peripheral device to the computer system. Thus, ports in the computer hardware are the jacks or sockets through which the peripheral devices are attached to the computer system. These ports are standardized for each purpose. There are several types of ports available in the computer system such as USB ports, Ethernet ports, display ports, serial ports, parallel ports, etc. Through these ports, we connect different hardware devices such as monitor, keyboard, mouse, etc. to the computer.
