MIS - Chapter 6: Telecommunications and Mobile Technology

Challenges of Wireless Networks

- Protecting against theft - Protecting wireless connections - Preventing Viruses and Mobile Devices - Addressing Privacy Concerns with RFID and LBS

Problem with LBS

- Target marketing: Subject is targeted without prior consent - Embarrassment: Customer's knowledge of another's location may lead to embarrassing situations - Harassment: Location data can be sued for harassment or attack - Service denial because a location for delivery is deemed unsafe - Legal restrictions: some countries regulate the use of personal data.

E-Business Network characteristics

- Transparent exchange of Data - Reliable and secure - Integrator and transactions framework - End-to-end integration and message delivery - Scalable processing

Factors inspiring the growth of wireless technologies

- Universal access to data and applications (more people are mobile and have access to more data than before). - Automation of business process (wireless technologies can centralize critical data and eliminate redundant processes). - User convenience, timeliness and accessibility.

WiMAX

A communication technology aimed at providing high-speed wireless data over metropolitan area networks. Requires a tower and a receiver.

Network

A communications, data exchange, and resource-sharing system created by linking two or more computers and establishing standards, or protocols, so that they can work together

MAN

A computer network that provides connectivity in a geographic area or region larger than that covered by a local are network, but smaller than the area covered by a wide area network

WAN

A computer network that provides data communication services for business in geographically dispersed areas (such as across a country or around the world).

LAN

A computer network that uses cables or radio signals to link two or more computers within a geographically limited area, generally one building or a group of buildings

GPS

A device that determines current latitude, longitude, speed, and direction of movement

Wi-Fi

A means of linking computers using infrared or radio signals

Value-Added Network

A private network, provided by a third party, for exchanging information through a high capacity connection.

RFID

A technology that uses active or passive tags in the form of chips or smart labels that can store unique identifiers and relay this information to electronic readers

Bluetooth

A telecommunications industry specification that describes how mobile phones, computers, and personal digital assistants (PDAs) can be easily interconnected using a short-range wireless connection

Virtual Private Network (VPN)

A way to use the public telecommunication infrastructure (e.g., Internet) to provide secure access to an organization's network

Microwave transmitter

Commonly used to transmit network signals over great distances

RFID tag

Contains a microchip and an antenna, and typically works by transmitting a serial number via radio waves to an electronic reader, which confirms the identity of a person or object bearing the tag

GIS

Designed to work with information that can be shown on a map

Telecommunication System

Enables transmission of data over public or private networks

Which technologies provides highest speed

Fibre-to-the-home

Difference between mobile and wireless

MOBILE: refers to technologies that travel with the user (but not necessarily in real time; users can download software, email messages, and web pages onto their smartphone, laptop, or other mobile device for portable or reference. WIRELESS is any type of electronic operation that does NOT use a hard wired connection, physical plug in a physical outlet.

Bandwidth

Measured the medium's capacity (measured the difference between the highest and lowest frequencies that can be transmitted on a single medium).

What is immediate, up-to-date information?

Real-time Information

Which technologies provides nearly universal coverage

Satellite

Advantages of VoIP

• Use existing networks and internet infrastructure • Cheaper than traditional phone service • Visual connection as well as voice • Ability to send reports, etc. through file transfer feature.
