Accepted Answer

The answer of Explain how a WAP cellular phone sends...

Question 7

An earth station transmits to a satellite at one frequency, and the satellite regenerates and transmits the signal back to earth at another frequency.

Accepted Answer

This is a standard configuration for satellite communication systems, known as the "uplink" and "downlink" frequencies. The earth station sends the signal up to the satellite on one frequency (the uplink), and the satellite receives, regenerates and retransmits the signal back to earth on another frequency (the downlink).

Question 8

Each Bluetooth device uses a ____________, which is special software that helps identify other Bluetooth devices.
A) frame
B) link manager
C) repeater
D) bridge

Accepted Answer

Each Bluetooth device uses a link manager, which is a special software that helps identify other Bluetooth devices. This software is responsible for establishing and maintaining connections between devices, managing power levels, and handling security protocols.

Question 9

Ultra Wide Band technology is used primarily for _____________________.
A) displaying Web pages on a cellular phone
B) connecting devices inside the home at very high speeds
C) finding the location of a car within a city
D) transmitting data at distances of up to 35 miles

Accepted Answer

Ultra Wide Band (UWB) technology is primarily used for connecting devices inside the home at very high speeds, enabling efficient and rapid data transfer between devices in close proximity.

Question 10

IEEE 802.11n devices can be as far as 375 feet apart and can send and receive data at up to ________ million bits per second (Mbps).
A) 75
B) 600
C) 100
D) 54

Accepted Answer

IEEE 802.11n devices can send and receive data at up to 600 million bits per second (Mbps) and have a range of up to 375 feet.

Question 11

Most Bluetooth devices can transmit data at up to 1 Mbps over a distance of 33 feet (10 meters).

Accepted Answer

This is true. Most Bluetooth devices have a range of up to 33 feet and can transmit data at speeds up to 1 Mbps. However, some newer Bluetooth technologies such as Bluetooth 5.0 can have faster data transfer rates and longer ranges.

Question 12

__________ uses wireless transmissions for data communications as much as 35 miles apart.
A) Wi-Fi
B) WirelessHD
C) WiGig
D) WiMAX

Accepted Answer

WiMAX (Worldwide Interoperability for Microwave Access) uses wireless transmissions to provide long-range data communications up to 35 miles away, making it the best choice among the given options. Wi-Fi, WirelessHD, and WiGig are all short-range wireless communication technologies.

Question 13

The new fourth generation (4G) cellular technology will allow data to be transmitted at a maximum speed of __________ Mbps.
A) 2 Mbps
B) 1 Gbps
C) 20 Mbps
D) 150 Mbps

Accepted Answer

Fourth generation (4G) cellular technology allows data to be transmitted at a maximum speed of 150 Mbps.

Question 14

A wireless network interface card performs basically the same functions and looks similar to a traditional network interface (NIC) card.

Accepted Answer

A wireless network interface card (WNIC) performs the same functions as a traditional NIC but connects wirelessly to a network instead of through a physical cable. It usually looks similar to a traditional NIC but may have an antenna or other distinguishing features for wireless connectivity.

Question 15

Explain the role of an access point (AP) in a WLAN.
An access point acts as a base station for all communications in a WLAN as well as an interface between the WLAN and the wired LAN.

An 802.11 wireless NIC, when configured to communicate with a wired network, sends its signals through invisible radio waves to ____________.
A) another computer directly
B) an access point
C) a wireless server
D) the Internet

Accepted Answer

When a wireless NIC is configured to communicate with a wired network, it sends its signals through invisible radio waves to an access point, which serves as a bridge between wireless and wired networks. The access point then passes the signals to the wired network. Therefore, choice B is the correct answer.
