Question 1

Location-based ____________ are wireless mobile content services which provide location-specific information to mobile users moving form location to location.

Accepted Answer

The answer of Location-based ____________ are wireless mobile content services...

Question 2

Radio frequency identification (RFID) technologies use active or passive tags in the form of chips or smart labels that can store unique identifiers and relay this information to electronic readers.

Accepted Answer

This statement is correct. RFID technologies use tags that can store unique identifiers and transmit this data to electronic readers. These tags can be either active (with a battery) or passive (relying on the energy from the reader to power them). Smart labels are a form of passive RFID tag.

Question 9

A global ____________ system is a constellation of 24 well-spaced satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location.

Accepted Answer

The answer of A global ____________ system is a constellation...

Question 10

Which of the following is not a benefit of WiMAX?

Accepted Answer

WiMAX is known for its long range, low cost, and wireless capabilities. However, it does not offer low bandwidth as a benefit. In fact, WiMAX is capable of providing high-speed broadband connectivity to remote or underserved areas, which requires high-bandwidth capabilities.

Question 11

A communications satellite is a big microwave repeater in the sky; it contains one or more transponders that listen to a particular portion of the electromagnetic spectrum, amplifying incoming signals, and retransmitting them back to Earth.

Accepted Answer

This statement is true. Communications satellites are designed to receive signals from Earth, amplify them, and send them back to another location on Earth. They act as repeaters in the sky, allowing signals to be transmitted over long distances without interruption. The transponders on the satellite are responsible for receiving, amplifying, and transmitting the signals.

Question 12

The Global Positioning System (GPS) is a constellation of 24 well-spaced satellites that orbit the Earth and make it possible for people with ground receivers to pinpoint their geographic location.

Accepted Answer

This statement is true.

Question 13

Location-based services (LBS) are wired content services that provide location-specific information to mobile users moving from location to location.

Accepted Answer

Location-based services (LBS) are typically wireless, not wired, and provide location-specific information to mobile users.
