Positioning or tracking in VANET is currently based on GPS. However, GPS is known to be prone to failure in case of emergencies. In addition, the current market penetration rate of GPS devices is low. Vehicles with built-in cellular communication capability are expected to be a part of the near future. Therefore, it is reasonable to assume that any vehicle possesses the functionality of a mobile unit...
With the widespread usage of mobile phones primarily due to their reduced costs, they are now not only being used for communication but can also assist law enforcing agencies to keep track of speeding vehicles or can be used by organizations to keep track of its employees. The three ways of tracking which are primarily in use are (a) via GPS (b) Using signal attenuation property of a packet and (c)Using...
Efficiency of present path loss models suffers when they are used in the environment other than for which they have been designed. The aim of this paper is to propose the predicting the path loss with the field measurement models and represent them in a more convenient form for the proposed fuzzy logic modeling. This paper proposes method to predict path loss for correct location of base station in...
InGaP-Plus, a manufacturable GaAs BiFET process has been developed at ANADIGICS for high volume production of ICs for the wireless and broadband businesses. The epitaxial structure is such that the HBT and pHEMT devices can be optimized independently, without compromise, for the application at hand. The process uses previously developed process modules and is only moderately more complex than a stand-alone...
This talk will focus on new technologies for multi mode client devices, and how these technologies can extend the service providers revenue model. The goal is keeping cost of delivery of services low while providing new applications for the emerging breed of client platforms. Wireless technology is becoming pervasive, with several new standards being added to the handheld cellular paradigm. While...
