MIS chapter 8

Internet of things

A scenario in which objects, animals, and people are provided with unique identifiers, and the ability to automatically transfer data over a network without requiring human-to-human or human-to-computer interaction

What are the three types of satellites circling earth

Geostationary-earth-orbit (GEO), medium-earth-orbit(MEO), and low-earth-orbit (LEO)

WiMAX

IEEE Standard 802.16 has a wireless access rang up to 31 miles

what makes the internet available to many people who otherwise could not access it

IoS

near-field communicaiton (NFC)

The smallest of the short-range wireless networks that is designed to be embedded in mobile devices like cell phones and credit cards.

Wireless local area network (WLAN)

a computer network in a limited geographical area that uses wireless transmission for communication

personal area network

a computer network used for communication among computer devices located close to one person

Wireless Fidelity (Wi-Fi)

a set of standards for wireless local area networks based on IEEE 802.11 standard

hotspot

a small geographical perimeter within which a wireless access point provides service to a number of users

Microwave transmission systems

a wireless system that uses microwaves for high-volume, long-distance, point-to-point communication

Satellite transmission systems

a wireless transmission system that uses satellites for broadcast communications

mobile portal

aggregates and provides content and services for mobile users

wireless access point

an antenna connecting a mobile device to a wired local area network

propagation delay

any delay in communications from signal transmission time through a physical medium

what was RFID developed to replace

bar codes

what is China expected GPS system going to be called... and European Union

beidou... Galileo

what type of transmission does satellites use

broadcast

Bluetooth

chip technology that enables short-range connection between wireless devices

Short-range wireless networks

connecting one device to another with a range of 100 ft or less

Mobilecommerce

electronic commerce transactions that are conducted with a mobile device

ultra-wideband

is a high-bandwidth wireless technology with transmission speeds in excess of 100 Mbps

MiFi

is a small, portable wireless device that provides users with a permanent Wi-Fi hotspot wherever they go

voice portal

is a website with an audio interface

LTE

is a wireless broadband technology designed to support roaming Internet access through smartphones and handheld devices. LTE is approximately 10 times faster than 3G networks.

global positioning system (GPS)

is a wireless system that uses satellites to enable users to determine their position anywhere on earth

XLTE

is designed to handle network congestion when too many people in one area try to access an LTE network. XLTE is designed to provide all users with no decrease in bandwidth

Latency

is the lag time it takes for the network or your device to respond to a command.

What does LTE stand for

long-term evolution

location-based commerce (L commerce)

mobile commerce transactions targeted to individuals in specific locations, at specific times

Mobile computing has two major characteristics that differentiate it from other forms of computing

mobility and broad reach

dematerialisation

occurs when the functions of many physical devices are included in one other physical device

cellular telephones

phones that provide two-way radio communications over a cellular network of base stations with seamless handoffs

Mobile computing

refers to a real-time connection between a mobile device and other computing environments, such as the internet or an intranet

broad reach

refers to the fact that when users carry an open mobile device, they can be reached instantly, even across great distances

passive RFID tages

rely entirely on readers for their power and can be read only up to 20 feet

what are the three factors that are preventing the commercial Wi-Fi market from expanding

roaming, security, and cost

Radio-frequency identification

technology allows manufactures to attach tags with antennas and computer chips on goods and then track their movement through radio signals

footprint

the area of Earth's surface reached by a satellite's transmission

line-of-sight

the transmitter and receiver are in view of each other

active RFID tages

use internal batteries for power, and they broadcast radio waves to a reader; and used for more expensive items

mobility

users carry a device with them and can initiate a real-time contact with other systems from wherever they happen to be

throughput

which is the amount of bandwidth actually available for you to use

telemetry

wireless transmission and receipt of data gathered from remote sensors
