- The Impact of Emerging RFID Technology in the Wirefree Environment for Automatic Identification, Data Collection and Dedicated Short Range Communication
- Radio Frequency Identification is a Dedicated Short Range Communication DSRC technology. With RFID, the electromagnetic or electrostatic coupling in the RF radio frequency portion of the electromagnetic spectrum is used to transmit signals. An RFID system consists of an antenna and transceiver, which read the radio frequency and transfer the...

- Design Methods for 3D RFID Antennas Located on a Conducting Ground Plane
- Radio Frequency Identification RFID is an emerging technology for remotely identifying assets and controlling devices via a wireless link. A typical RFID transponder tag consists of an antenna and an integrated circuit chip which stores an identification number and other information. The passive RFID tags are usually the least expensive...

- Towards a Transponder for Serial 100 Gigabit Ethernet Using a Novel Optical SERDES
- Video, data-center and mobile backhaul traffic promises to dominate much of metro traffic in the near future causing speculation for bandwidth exhaustion in the C-band. This has led to motivations for 100 Gbps per wavelength proposals especially in the Ethernet space. The 100 Gbps Ethernet GE proposals are currently being...
