820 Abstract—Advancements in broadband and mobile communication have provided many privileges to its subscribers, such as high-speed data connectivity and good quality voice and video application services for economical rates. WIMAX is an eminent technology that provides broadband and IP connectivity to “last mile” scenarios. It offers both line of sight(More)
The proposed frequency band for a 4G mobile system is 2 to 8 GHz, while the proposed access for the system is MC-CDMA / OFDM. In this paper, a new access technique has been proposed, with the bandwidth of the system divided into ten sub-bands. Each sub-band has40 channels and the access is a multiband of the carrier CDMA (MBC-CDMA). The proposed access(More)
Radio Frequency Identification (RFID) and Wireless Sensor Network (WSN) are two important wireless technologies that have variety of applications and provide unbounded future potentials. However, RFID and sensor networks nearly are under growth in similar way. Integration of RFID and wireless sensor networks attracts little attention from research(More)
An active radiofrequency identification using ZigBee standard with sleep mode configuration has been developed. Tags are designed using non beacon mode with periodic data communication and intermittent data communication. Both tags are programmed in sleep mode. In periodic data communication, the tag is programmed to sleep for 5s and wakeup for 2.6s to(More)
Radio frequency identification (RFID) technology has been recently adopted as an automated data management system in many areas, especially in supply chain management systems. However, research and studies on EPC Class-1 Generation-2 (Gen 2) RFID technology-based university communities are relatively few. Ultra high frequency (UHF) RFID technology has(More)
