Wireless sensor network

5 Proximity Sensor 5.1 Introduction A proximity sensors is the sensor able to detect the presence of nearby objects without any physical contact. A proximity sensors often emits an electromagnetic field or a beam of electromagnetic radiation, and looks for changes in the field or return signal. The object being sensed is often referred to as the proximity sensor's target. Different proximity sensor target demand different sensor. For examples a capacitive or photoelectric sensors might be…

External Environment Analysis Analyzing the external environment of Verizon, requires the use of PESTEL and Porter’s five forces model. Threat of Entry: Low threat. New entrants don’t present a problem to Verizon. Establishing a wireless company is expensive, it requires a substantial amount of capital, work and resources, and additionally it requires to comply with government regulations that could take a high number of years to comply with, something that dissuades new comers. Power of…

Do you know what an RFID tag does? An RFID tag is a small microchip placed into things like: supermarket items(known as the barcode), inside people, pets, computers, phones, etc. to track them down, read their data and transfer files to and from. An RFID tag is a Radio frequency identification device(Tag You're It 72). It contains radio frequency which means anyone with an RFID tag reader can receive radio waves and see whatever the RFID tag contains. Even Though RFID’s track kids and pets that…

make it different from MANET. These characteristics include: 1. Each vehicle is turned into a router or wireless node with the capability to connect and become a part of a network in the range of approximately 100-300m. 2. Network topology changes as the vehicles fall out of range or new vehicles join the network, thus making the network density vary according to traffic density. For example, network density can be very high when in a traffic jam, or very low in suburban traffic. 3. Mobility in…

devices during classes has been a discussed issue for long, because of problems regarding the safety of the wireless connection, the costs of using these kind of devices for learning institutions and the personal use each student does with them. Many researchers argue that technologies used during lectures are only damage for students, because they tend to pass their time on social networks or surfing in Internet rather than follow the lesson. According to Dr. Claire La Roche and Dr. Mary…

worldwide. However, there are few questions that are being discussed among research institutions, standards bodies, operators, the supplier community, trade organizations and governments – What will be the 5G deployment time frame? What will characterize networks beyond 2020? What are the likely technologies that will come in to play for 5G? This paper is a survey paper, in an attempt to address these questions in a systematic way. This paper presents the 5G use cases, requirements, spectrum…

NFC and RFID Radio Frequency Identification (RFID) is a wireless use of electromagnetic fields to transfer data, aiming to automatically identifying and tracking tags attached to objects. Near Field Communication (NFC) is one specific type of RFID, and shares many physical properties with it. The differences between NFC and RFID is that many extra properties were developed for NFC to enable secure mobile payments. 1.1. Radio Frequency Identification (RFID) RFID was first patented in…
