Deck 23: The Cellulare/PCS Telephone Network

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.

Answer 1

base

Question 2

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

Answer 2

transceiver

Question 3

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

Answer 3

False

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:

A) in this modern age, most people don't stay at home very much, so the exposure is quite limited
B) the signal power is so low
C) the power stays high above the ground, well above the height of humans
D) actually, the root of this question is wrong, cellular radio towers are known to cause blood dyscrasias in susceptible nearby residents

Question 5

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

Question 6

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

A)the service is inexpensive
B) cellular phones were created for use while driving
C) the entire call travels through the air
D) none of the above

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.

Question 8

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

Question 9

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

Question 10

TDMA and CDMA, also referred to as ________ communications services, are the newer digital standards used to carry signals in the cellular network.

Question 11

The oldest and simplest standard used in the cellular network is:

A) FDM
B) TDMA
C) CDMA
D) AMPS

Question 12

The most widely used cellular standard in North America today is:

A) FDM
B) TDMA
C) CDMA
D) AMPS

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.

Question 14

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

Question 15

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

Question 16

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

A) increased number of subscribers per cell
B) increased security provided by spreading the information across the spectrum
C) reduced chance that the call will be lost during handoff
D) reduced power consumption of the telephones due to the way the bits are transmitted and received
E) all of the above

Question 17

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

A) transmitter
B) receiver
C) antenna
D) diplexer
E) frequency synthesizer
F) logic board

Question 18

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

A) transmitter
B) receiver
C)antenna
D) diplexer
E) frequency synthesizer
F) logic board

Question 19

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

A) 5 watts
B) 7 watts
C) 6 watts
D) 13 watts

Question 20

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

Question 21

Billing a cellular customer for time on line is a responsibility of the ________ switch.

Question 22

Users of the On-Star network when driving are taking advantage of V and H ________.

Question 23

V and H coordinates are often used to identify a(n) ________ on earth.

Question 24

Signaling in the cellular network includes the:

A)cellular telephone to the MTSO
B) base station to the MTSO
C) MTSO to the outside world
D) all of the above

Question 25

Calls passing between cellular networks do not depend on SS-7 messages in the same way that local and long distance networks depend on SS-7.

Question 26

________ is the signaling protocol used by cellular networks that is the standard used to connect the MTSO and the BTS.

Question 27

One advantage introduced by the cellular telephone revolution has been the greatly simplified system of billing over the old-fashioned method.

Question 28

Most cellular telephone bills show a(n) ________ charge plus the minutes-per-use charge.

Question 29

The most complaints from users of cellular telephones stem from:

A) the need to charge the battery too often
B) other users who carry on loud conversations in public places
C) roaming costs and technical difficulties
D) having car accidents while using the phone and driving simultaneously

Question 30

The cellular feature permitting the caller to correct the digits of a dialed call before the call is sent is called ________ dialing.

Question 31

Setting your cell phone to vibrate when a call is being received would require that you used the ________ ringing feature.

Question 32

The cellular telephone feature that is similar to having a Rolodex is called ________ memory.

Question 33

A brain cancer scare in 1999, as well as the increased number of automobile accidents blamed on cellular use while driving, have increased interest in ________-________ phones

Question 34

Although carrying data over a cellular network is not as common as carrying data across a wire-line network, it can be done so long as you're using the digital cellular network

Question 35

The first consortium to deploy satellite telephony, whose intent is to provide dial tone anywhere in the world without the need for wires, cellular towers, or other land-oriented connections is:

A) Globalstar
B) Teledesic
C) Iridium
D) all of the above share the same objective and were deployed at the same time

Question 36

Discuss the similarities and differences between the cellular MTSO and the line-wire central office.
