In Today's world RFID (radio frequency identification) technology is one of the most popular technologies for tracking and tracing, whereby a person or an object is identified using Radio Frequency (RF) transmission using a special kind of a sensor network. Recently, radio frequency identifications (RFIDs) are used to identify the assets which are permanent objects used internally in business. ...

The application background and basic structure of train control system based on the combination of Radio Based Cab Signaling (RBCS) and Automatic Train Protection (ATP) is introduced. The architecture of the data transmission network used for RBCS is analyzed in detail, together with the reliability of radio data

In the keynote paper for the previous HF Radio Systems and Techniques Conference, Cook (1) demonstrates that “in the information age” there is a resurgence of interest in HF radio — in marked contrast to its oftenpredicted demise. Cook gives examples of new systems in use or under development for a range of applications, especially those involving data transmission, and makes the pertinent obse...

Coherent detection of orbital angular momentum in radio Report Title The angular momentum propagated by a beam of radiation has two contributions: spin angular momentum (SAM) and orbital angular momentum (OAM). SAM corresponds to wave polarisation, while OAM-carrying beams are characterized by a phase which is a function of azimuth. We demonstrate experimentally that radio beams propagating OAM...

Distribution of software over-the-air in sensor networks requires radio transmission energy that is proportional to the size of the software image. Because the radio transceiver is one of the most energy consuming devices on sensor nodes, it is important to reduce the size of the software. This poster presents the results of using a variety of different data compression algorithms to trade-off ...

Abstract. TNC controllers are microprocessor systems, used for data transmission in Packet Radio network that may be considered as an example of a wireless, wide area network. On the basis of Packet Radio infrastructure we may also form telemetric and remote control network using APRS protocol. TNC controllers may cooperate with other similar networks as well. In this paper, an analytical model...

In this paper, Radio Frequency IDentification (RFID) tag set cardinality estimation problem is considered under the model of multiple independent reader sessions with unreliable radio communication links in which transmission errors might occur. After the R-th reader session, the number of tags detected in j (j = 1, 2, ..., R) reader sessions is updated, which we call observed evidence. Then, i...

A radio frequency identification (RFID) system is a special kind of sensor network to identify an object or a person using radio frequency transmission. A typical RFID system includes transponders (tags) and interrogators (readers): tags are attached to objects/persons, and readers communicate with the tags in their transmission ranges via radio signals. RFID systems have been gaining more and ...

The IEEE 802.16m based broadband wireless access is a brand-new technology to provide high speed and wide range communications for wireless users. However, how to exploit the optimal utilization of the radio frequency bands resource in such networks is a big challenging issue as it covers the radio channel capacity optimization, channel bandwidth utilization optimization and utilization perform...

Due to the ever growing need for spectrum, the cognitive radio (CR) has been proposed to improve the radio spectrum utilization. In this scenario, the secondary users (SU) are permitted to share spectrum with the licensed primary users (SU) with a strict condition that they do not cause harmful interference to the cognitive network. In this work, we have proposed an interference model for cogni...
