Chek mate geolocation analyzer
This document summarizes a presentation given by Jongwook Woo at California State University Los Angeles on December 1st, 2016. The presentation introduced big data concepts and how the team implemented a geolocation analysis of crime data from Chicago using Hadoop Hive on the Microsoft Azure cloud. Visualizations of the results showed crime types by occurrence, tables of crime data, and a map highlighting safer and less safe areas of Chicago based on the analysis. The team concluded the analysis could help people search for safer places to live and potentially integrate with rental companies.
HTML5 Geolocation API
This document summarizes a presentation on geolocation. It defines geolocation as using location technologies to determine the real-world geographic location of a device. It discusses the history and rise of geolocation on the web from 2009 onward. It then covers various location technologies like IP geolocation, triangulation, GPS, Wi-Fi and cell towers. It provides code examples and applications of using geolocation such as finding nearby points of interest, turn-by-turn navigation, and geotagging photos taken on mobile devices.
Wi-Fi Tecnology
Wi-Fi, also known as wireless fidelity, allows devices to connect to the internet without cables. It uses radio waves to transmit and receive data between devices within range of a wireless access point. Common Wi-Fi standards include 802.11b, 802.11a, and 802.11g. A Wi-Fi network requires an access point connected to a wired network, wireless network cards or adapters in devices, and may include additional components like antennas, bridges, and firewalls for security. Wi-Fi provides mobility and flexibility but can experience interference issues and has a limited range compared to wired connections.

W3C Geolocation API - Making Websites Location-aware
The document discusses the W3C Geolocation API, which allows websites to detect the user's location. It provides an overview of the API and location technologies, examples of how to use the API, and upcoming geo events. The API allows websites to get the user's location either once or periodically with callbacks that return position and error objects. Common location technologies discussed are IP geolocation, GPS, Wi-Fi, and cell tower triangulation.
Wi Fi
Wi-Fi is a wireless networking technology that uses radio waves to provide wireless internet access. It allows devices to connect to a network wirelessly without needing cables. A Wi-Fi network uses wireless access points or routers to connect wireless devices to a wired network. Access points can provide internet access within their range to connected devices. While convenient, Wi-Fi networks have limitations such as a limited range, potential security issues, and signal interference between devices.
Vehicular Networks
This document discusses using vehicular networks to disseminate information for applications like traffic and parking management. It proposes that vehicles equipped with sensors and wireless connectivity could form ad hoc networks to share real-time data. This would allow more efficient routing, reduced wait times, and savings on fuel. Several data dissemination approaches are described, including vehicle-to-infrastructure, vehicle-to-vehicle, and an epidemic dissemination method. Challenges with scalability, mobility, and reliability are also discussed. The goal is to explore how vehicular networks can efficiently distribute large amounts of sensing data in dynamic mobile environments.
Wlan 802.11n - MAC Sublayer
The document discusses the MAC sublayer in the 802.11n wireless LAN standard. It describes how the 802.11n MAC sublayer aims to improve protocol efficiency, support quality of service standards, and minimize contention overhead through techniques like selective retransmission. It also examines how the 802.11n MAC protocol operates in different modes and addresses problems like hidden and exposed nodes through physical and virtual sensing methods.
Microwave oven
Microwaves are a form of electromagnetic radiation used in communications and cooking. Microwave ovens work by using a magnetron to generate microwaves around 2.45 GHz, which are transmitted into the oven cavity and absorbed by water molecules in food, causing them to heat up rapidly. The first microwave oven was invented accidentally in 1947 when a researcher discovered that microwaves could cook food quickly. Modern microwave ovens have safety mechanisms to prevent exposure to high levels of microwaves.
Vehicular ad hoc network
This document discusses vehicular networks. It defines vehicular networks as mobile ad hoc networks that allow vehicle-to-vehicle and vehicle-to-infrastructure communication. The key components are the vehicles themselves that form the mobile nodes, and roadside infrastructure that helps enable intelligent broadcasting. Example applications include electronic brake lights, traffic information systems, and traffic safety/management services.
Vehicular network
Vehicular networks allow vehicles to communicate with each other (vehicle-to-vehicle) and with roadside infrastructure (vehicle-to-infrastructure). Vehicles act as moving nodes that form a mobile ad hoc network (MANET). Key aspects include dynamic topology, location-based routing protocols, and applications related to safety, traffic management, and infotainment. Communications can be unicast, multicast, or broadcast between vehicles and infrastructure to support functions like electronic brake lights, platooning, and traffic information systems.
Mechanism of a Microwave Oven.
A microwave oven works by using a magnetron to generate microwave radiation that vibrates the water molecules in food, causing them to heat up and cook the food. Specifically, (1) a magnetron generates microwaves around 2.45 GHz, (2) these microwaves cause polar molecules like water to rotate and produce heat through dielectric heating, and (3) a waveguide and stirrer distribute the microwaves evenly inside the oven cavity to cook the food quickly and efficiently. Microwave ovens offer advantages like saving time and energy compared to conventional cooking methods.
Adhoc network
1. Vehicular ad hoc networks (VANETs) use vehicle-to-vehicle and vehicle-to-infrastructure communication to share safety information, improving road safety.
2. VANETs allow vehicles to form a temporary network without any preexisting infrastructure, distributing real-time information to avoid accidents.
3. Current research focuses on applications for traffic scenarios, as well as addressing challenges relating to network topology, routing mechanisms, security, and minimizing power consumption.

The document then focuses on geolocation aspects in LTE, outlining the control plane and user plane positioning approaches. It discusses the LPP and SUPL positioning protocols and technologies like E-CID, TDOA and A-GNSS. Indoor geolocation techniques including triangulation methods and wireless technologies are also covered. Finally, geolocation on iOS and Android platforms and other systems like GLONASS are summarized.
Ultra wide band
This document provides an overview of ultra-wideband (UWB) technology. UWB uses short radio pulses rather than modulated carrier waves for communication. It has advantages like high data transfer rates, low power usage, immunity to interference, and ability to pass through obstacles. UWB can be used for applications such as wireless local area networks, sensor networks, tracking/positioning, and communications. The document discusses UWB principles, technologies like impulse radio, challenges including standardization, and potential applications and advantages of UWB technology.

Indoor geolocation
Indoor geolocation is an emerging technology that has applications in commercial, public safety, and military domains. It uses various techniques like RSS, AOA, TOA, and TDOA to locate tags or mobile devices within buildings. Key challenges include multipath effects from the indoor environment and lack of line of sight between devices, which reduce location accuracy. Existing short-range technologies like RFID have limited range, while mid-range options have reliability issues. The 3D-iD system presented a potential solution using an indoor antenna infrastructure and cell controllers to determine tag locations through triangulation of signal distances to multiple antennas.
Wi-Fi Wireless Fidelity
The document discusses wireless fidelity (WiFi) and IEEE 802.11 standards. It describes the setup required for WiFi including access points and wireless cards. It then covers how WiFi works using radio waves, the network topologies of AP-based and peer-to-peer, and common WiFi security threats like eavesdropping and denial of service attacks. It also lists advantages, disadvantages, and applications of WiFi networks.
