Trackinging And Tracking

The objective of this lab is to learn how to use the Tutor TIMS software to build and analyze a communication system. This lab required us to use Audio Oscilloscope, Adder and Tuneable LPF in order to get the required frequency signals.

CE3.18 High gain-antennas were one of the important requirements of this new network architecture design. I was tasked with design selection and implementation process

The evolution of wireless technologies in modern days helps to utilize these kind of technology in many applications like vehicle safety application, a wireless data communication between the vehicles and also between the vehicles and other infrastructure.

Since their emergence, wireless networks have become increasingly popular. There are currently two kinds of wireless networks in use, namely WLAN’s and Ad Hoc. WLAN’s are called infrastructure networks as they have fixed and wired gateways, whereas Ad hoc are called infrastructure less networks as they don’t have any fixed routers, all nodes in this are capable of movement and can be connected

At the beginning, in 1997, there was just one standard – 802.11 with 2.4Ghz frequency band and transfer rate up to 2Mbps. Recent days we have more than 10 different and more or less popular types of 802.11 standards.

As Reed (Reed, 2002) and others have stressed out, that the benefits of SDR approach go way beyond the multimode operations. Other benefits stem from the flexibility that comes with programmability. For instance, it can simplify design by allowing reuse of a common RF front end with new designs or modes of operation available through software changes. It also enables improvements to radio performance and functionality through application of digital signal processing (DSP) to implement adaptive beamforming, interference mitigation, and numerous other techniques either proven or in development. As the SDR approach has gained traction, a variety of hardware and software tools for development and exploration have become available. These tools are broadly accessible with reasonable cost and ease-of-use enabling new opportunities for engineering education and research. Examples include National Instruments (NI) universal software radio peripheral (USRP)/ NI LabVIEW software , the Ettus Research USRP/ GNU’s Not Unix (GNU) Radio, WARP , the Lyrtech SDR Platform and the IMEC SDR Platform. For researchers, these platforms can provide a starting point for development of prototypes operating on live signals. Such prototypes can effectively demonstrate the practical viability of an implementation and are a step toward end deployment.

CE 1.21 I created a virtual RF environment using an RF modelling tool called AirMagnet planner. I installed a single AP in the location site and simulated different virtual APs on the floor

Communication technologies have been in constant evolution during the past decades. Amongst these digital communication is very relevant. The advent of the digital processor enabled us to perform the complex tasks of communication such as transmission and receiving using a programmable system. This led to the development of a new radio paradigm called Software Defined Radio (SDR). I believe that software is increasing replacing hardware due to it's scalability and cost effectiveness; this idea propelled me to research in this domain. \cite{0001}

This paper surveys the research on AR from early efforts in 1990s to 2010s, and describes the most important trends, issues, and solutions. There are several other surveys which can be used to get a more detailed picture of the research in this area (R. Azuma et al., 2001; R. T. Azuma, 1997; Dünser, Grasset, & Billinghurst, 2008; Huang, Hui, Peylo, & Chatzopoulos, 2013; Papagiannakis, Singh, & Magnenat‐Thalmann, 2008; Van Krevelen & Poelman, 2010; Welch & Foxlin, 2002; Zhou, Duh, & Billinghurst, 2008).

Abstract—Although fingerprint based localization is promising for indoor applications, its accuracy remains a huge challenge. Most existing approaches depends on the Radio Signal Strength (RSS) to generate fingerprints. Merely using RSS is unable to accurately localize since such an one-dimensional fingerprint is serious influenced by the interference and multipath effect in the indoor environment. In this paper, we propose a new localization approach based on multidimensional WiFi fingerprint. Instead of using RSS only, we employ RSS, transmitted power, and channel information to construct fingerprints. The extension of fingerprints enables fine-grained localization and tracking services. We also deign a cosine similarity based matching algorithm and enhanced particle filter mechanism to realize the localization and tracking. Extensive experiment and implementation results show that using the new fingerprint can achieve an accuracy within 2m in 90% testing points, with good adaptability to complex indoor environments.
