Question 1

An antenna where cellular calls are sent and received, then sent to the next station and eventually to the called party, is called a cellular ________ station.

Accepted Answer

base

Question 2

The base ________ station consists of the cellular antenna, the base station equipment, and the telephone company cable.

Accepted Answer

transceiver

Question 3

In the cellular network, one base station is placed in each cell, preferably at the lowest point in the area.

Accepted Answer

In a cellular network, one base station is typically placed in each cell, but it is preferably located at a high point in the area to ensure optimal coverage and signal strength.

Question 4

The public's concern that cellular radio towers may cause illness to residents living close to the tower is hard to justify because:

Accepted Answer

The signal power emitted by cellular radio towers is very low and is not considered harmful to human health according to current scientific evidence.

Question 5

Unfortunately, there really is nothing that can be done about the ugly appearance of cellular towers.

Accepted Answer

Cellular towers can be disguised as other structures, such as trees, or integrated into existing structures like buildings or lamp posts to make them less visually intrusive.

Question 6

The biggest misconception by the public concerning cellular telephone service is that:

Accepted Answer

The answer of The biggest misconception by the public concerning...

Question 7

The main difference between a cellular call and a wire line call is that cellular uses radio frequencies in the last mile to reach the end customer's cellular telephone.

Accepted Answer

Cellular calls use radio frequencies to connect the call from the cell tower to the end user's mobile phone, which is the "last mile" connection in cellular communication. Wireline calls, on the other hand, use physical cables (like copper or fiber) for the entire route, including the last mile to the end user's location.

Question 8

In order to avoid ________ between cells, adjacent cells are not allowed to use the same frequencies.

Accepted Answer

The answer of In order to avoid ________ between cells,...

Question 9

The beauty of cellular architecture is its ability to ________ frequencies with the region, thereby increasing the number of subscribers on the network.

Accepted Answer

The answer of The beauty of cellular architecture is its...

Question 10

Question 13

________ technology increases the number of calls that can travel across the same frequency spectrum by using frequencies only when there is a conversation going on and compressing the voice signal from a 64 kbps to an 8 kbps word.

Accepted Answer

The answer of ________ technology increases the number of calls...

Question 14

________ technology uses a technique referred to as "spread spectrum"when transmitting signals from the cellular phone to the BYS.

Accepted Answer

The answer of ________ technology uses a technique referred to...

Question 15

The advantage of "spread spectrum"is the increased number of subscribers per cell, as multiple signals can now use the same frequencies.

Accepted Answer

Spread spectrum technology allows multiple signals to share the same frequency band by spreading the signal over a wider bandwidth, which increases the capacity of a system to handle more subscribers or data traffic within a given frequency band. This is achieved through techniques like frequency hopping or direct sequence spreading, which make more efficient use of the available spectrum.

Question 16

Which of the following is an advantage of using the CDMA standard?

Accepted Answer

CDMA (Code Division Multiple Access) technology offers several advantages, including increased capacity for subscribers per cell due to its spread-spectrum technology, enhanced security because the information is spread across a wide frequency band, and a reduced chance of call drops during handoff between cells. Additionally, CDMA's power control mechanisms allow for reduced power consumption in mobile devices, making all the listed options correct advantages of using the CDMA standard.

Question 17

In the cellular telephone, the ________ is viewed as the "brain"of the unit.

Accepted Answer

The logic board in a cellular telephone is considered the "brain" of the unit because it contains the central processing unit (CPU) and other crucial components that control the device's operations, similar to how a motherboard functions in a computer.

Question 18

In the cellular telephone, the ________ is responsible for converting the reference frequency to the appropriate frequency for that particular cell.

Accepted Answer

The frequency synthesizer in a cellular telephone is responsible for converting the reference frequency to the appropriate frequency for that particular cell, allowing the phone to communicate effectively within the cell's frequency range.

Question 19

Although a typical cellular phone requires much less, the FCC maximum power output for a cellular telephone is:

Accepted Answer

The answer of Although a typical cellular phone requires much...

Question 20

Like the wire-line network, cellular calls are billed on an outgoing basis only.

Accepted Answer

Cellular calls can be billed for both outgoing and incoming calls, depending on the user's plan and country-specific billing practices.
