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
