Q2A GPS satellite develops a fault whereby it moves into an orbit 19 500 km above the Earth’s surface and also emits
a weak signal whose power is only 25 W. What will be the power per square metre of the signal received on the Earth’s
surface? Choose the nearest value from the list below. (W/m2 represents ‘watts per square metre’.)
Select one:
3.0 x 10−4 W/m2
5.2 x 10−9 W/m2
5.2 x 10−15 W/m2
5.2 x 10−17 W/m2
2.1 x 10−16 W/m2
1.0 x 10−4 W/m2
1.0 x 10−7 W/m2
Q3- In a mobile phone network, how many times as strong would a signal be expected to be at 400 m from a base station,
compared with at 200 m? Choose the nearest value from the list below.
Select one:
0.002
0.004
0.0625

Q4- In a particular phase modulation system, each symbol is able to represent 3 bits. What sort of PSK is being used?
Select one:
plain PSK
QPSK
8PSK
16PSK
64PSK
256PSK
Q5- Select the two true statements from the following list.
Select one or more:
If 16 digital signals are to be time-division multiplexed, and if each signal has a bit rate of 200 kbit/s, then a channel
that can support a bit rate of 3 Mbit/s should be adequate.
A channel of bandwidth 400 kHz should be able to support a signalling rate of 500 kilobaud.
A channel of bandwidth 500 kHz can carry no more than 5 frequency division multiplexed signals if each signal has a
bandwidth of 70 kHz.
According to the convention described in the mini-encyclopaedia in the Block 2 Document Book, a voltage of 10
nanovolts would be written as 10 nV.
In amplitude modulation, the amplitude of the carrier is modulated in response to the frequency of the signal.
Q6- Select the two true statements from the following list.
Select one or more:
In GSM, over 75% of the bits in each TDMA frame are available for the message data.
In cellular telephone systems, dividing an area up into more cells is a means of enabling the system to accommodate
more users.
In order to keep track of a mobile phone that is moving around, information about its position may be stored
simultaneously in several VLRs.
The air interface for analogue mobile phones in the UK was TDMA.
In GPRS, a circuit-switched network of GPRS nodes exists alongside the circuit-switched network of mobile switching
centres.
Q7- Select the two true statements from the following list.
Select one or more:
In CDMA, each individual bit in the message is replaced by a binary code word known as a code sequence.
High latency is much more of a problem in live videoconferencing than it is in file transfers.
In both UMTS and HSDPA the spreading factor is fixed at 16.
In CDMA, several messages can be sent simultaneously in the same cell only if they occupy either different frequency
bands or different time slots.
Wideband CDMA is so called because a wider range of users can be accommodated than in plain CDMA.
Q8- Select the two true statements from the following list.
Select one or more:
If a single company offers a cable service for TV, broadband internet access and fixed telephone services, and also
offers a mobile telephone service, then this is quadruple play commercially but not technically.
LTE Advanced is aiming to reach a peak upload data rate that is 5 times as great as that in LTE.
If a 4 MHz band is being used for LTE then the planned peak data rate is 25 Mbit/s for the downlink and 12.5 Mbit/s
for the uplink.
Mobile WiMAX 2.0 uses OFDMA in both the downlink and the uplink whereas LTE uses OFDMA only in the
downlink.
In LTE, the subcarriers are spaced at 12 kHz and individual users will be allocated to blocks of 15 channels.
Q9- Select the two true statements from the following list.
Select one or more:
None of the following is a permitted number of bits for a pseudo-random binary sequence: 6, 15, 65, 144.
Differential GPS can help a GPS receiver to make some correction for errors that are due to the fact that the speed of
radio waves in the Earth’s atmosphere is different from their speed in a vacuum, but it cannot enable the receiver to make a
full correction.
Assisted GPS is a process whereby a stationary device can supply signals to nearby mobile GPS receivers in order to
enable them to get an initial fix on GPS satellites more quickly.
In GPS, the clocks in the receivers are much more accurate than those in the satellites but a signal from a fourth
satellite can help to correct this problem.
The signal from a GPS satellite that is near the horizon will take less time to arrive at a GPS receiver than will the
signal from that same satellite when it is overhead.
Q10- A company is interested in employees’ journeys into work in the morning. There are three phrases missing from the
following statements about visualising data. Drag and drop from the list below the options that correctly give the missing
phrases 1 to 3.
•
A[
]would be a suitable representation for showing the trend in average journey time for those travelling to
work by car over the past 10 years.
•
A[
]would be a suitable representation for comparing the proportion of employees in the following categories:
those that walk to work every day, those that walk to work some days, and those that never walk to work.
•
A[
]would be a suitable representation of the total number of employees that walked to work, cycled to work,
came by car, and came by public transport on a given day.

Errata in the Block 2 main text
Page 99, seven lines from the bottom of the page
Insert ‘packet-switched’ before ‘parallel network’ so that the sentence reads
‘The solution to this problem was to provide an upgrade to GSM whereby a
packet-switched parallel network was provided to handle data transfers.’
Page 99, five lines from the bottom of the page
Delete ‘which is packet-switched’, so that the sentence ends after ‘(GPRS)’
and reads ‘That upgrade is known as general packet radio service (GPRS).’
Page 104, first paragraph under Figure 3.B5
This paragraph should make it clear that the term ‘symbol’ here means the
pair of bits being represented by a phase shift. More generally, ‘symbol’
means a group of bits of any size being represented by a phase shift.
Page 133, penultimate line in the answer to Activity 3.3(b)
The final term in should be ‘915 MHz’ so the line should read ‘890 MHz +
(999 × 25) kHz to 915 MHz.’
Page 192, Figure 7.1 caption
Replace ‘compare and/or contrast’ by ‘recommend’ so that the caption reads
‘A visualisation of two structures for the purpose recommend’.

Welcome to Exploring and enquiring, the second block of T215
Communication and information technologies.
The technologies in this block are focused around mobile phones and the
network features that support their use. This is a fast-changing topic, and so
the approach is to look at trends: what has been changing and what has been
staying the same, and how this is likely to play out in the future.
The T215 team accept that, however hard we try, we cannot keep wholly up
to date in a module like this; things seem to change almost daily. Therefore
our aim is to give you the tools to keep yourself up to date. To that end, the
materials include some passages, and even whole documents, that have not
been specially prepared for T215, together with support in reading them and
extracting information from them. So our hope is that you emerge from this
block not only more knowledgeable about mobile devices and mobile
networks but also more able to read about their developments with
understanding in the future.
A sub-theme of the block is a continuation of the work you started in
Block 1 on writing documents and critically evaluating them. You will carry
this work into short reports towards the end of the block.
And finally, the block contains one entirely fresh communication topic:
visualising data. Software tools for visualising data in new ways have been
taking huge strides over the last few years, and we aim to introduce you to
some of the many ways in which such tools can help in making sense of
data. This part of the block is online so that you can readily access examples
and tools.
Study materials
The Block 2 study materials include some resources that are exclusively for
the block and some that are shared with other blocks in the module.
The resources that are exclusively for the block are as follows.
.
Exploring and enquiring, which is the principal component and is
divided into nine parts of which seven are in printed form and two
(Parts 6 and 9) are presented on the T215 website.
.
Block 2 Document Book, which you will need to refer to as you study
Parts 2, 3 and 4.
.
This Companion, which you are strongly advised to print and keep to
hand as you study the block, not only for this study guide, but also
because it contains the first part of the assessment for the block –
TMA 02.
.
iCMA 42 – the second part of the assessment for the block. This is
online and can be accessed from the T215 website directly below the link
to this Companion.
.
Three documents that you will need to use with Part 8 Critically
evaluating and improving a short report and that are available to
download from the Block 2 Study items page of the T215 website.
3
Block 2 Companion 2014J
These are in the files T215_B2_P8_ShRpt_A.pdf,
T215_B2_P8_ShRpt_A_Rev_1.pdf and T215_B2_P8_ShRpt_B.rtf.
There are three resources that are shared with other blocks in the module.
.
The T215 Numeracy Book, which you may need as you study Parts 3
and 5. There are explicit cross-references to this book at appropriate
points in these two parts to direct you to it if you need it.
.
The T215 module forums, your tutor group forum and group forum (see
more on this in the next section), which you can access via the T215
website.
.
Your personal wiki and group wiki (see more on this in the next section),
which you can access via the T215 website.
And finally, you will need to use material from the T215 DVD in Parts 2
and 5 of this block. You have the choice of installing this material on to
your hard disk or running it directly from the DVD. If you choose to install
it, full instructions are available with the DVD.
Working in a group
In order to complete Question 4 of the TMA for this block, you will need to
work with a small group of other students. Your tutor will organise these
groups and you will be able to communicate with the other members using a
forum that your tutor will set up. You will be working in these groups more
extensively in Block 3, so it is a good idea to start communicating with your
group via the group forum straight away.
There are two main reasons why group work is introduced in this block and
is central to the next block:
.
working with others is itself an important skill
.
collaborating with other students is a valuable way of learning.
Over the years, universities have consulted employers about what they are
looking for in prospective employees. The responses are usually expressed in
terms of skills rather than subject knowledge. Interpersonal and teamworking skills come high on the list – employers want staff who can work
well with others. Working with other people, and discussing ideas, also gives
you the opportunity to see things from different perspectives and to learn
from the experiences of others. In an Open University module this is
particularly valuable, as your fellow students have such a wide range of
knowledge, skills and experience.
More details about what is required in terms of group work for Block 2 are
provided later in the TMA and for Block 3 in the Block 3 Companion.

Study guide
Study plan
This block is designed to occupy five weeks of your study time, which
means that you should expect to spend around 80 hours in total studying it.
In planning your study time, you should take the following into account:
.
The nine parts into which the block is divided are not of equal length.
.
Parts 6 and 9 are to be studied online whereas the other seven parts are
printed material, with occasional use of a computer. (You could, if you
wish, print out Part 6 and study it on paper, but this would not be
possible for Part 9.)
.
In the next block – Block 3 – you will be collaborating with some of the
other students in your tutor group to create resources in a wiki and to
produce a website. You and your other group members will need to do
some planning for this collaboration while you are studying Block 2, and
there is a question in TMA 02 that relates to this planning. You should
look at this question and start to engage with the planning near the start
of your study of the block.
Table 1 is intended to help you to plan your study of the block. The study
plan in Table 1 assumes that you will do some work on the assignments as
you go along, and will use the remaining time in the fifth week to review the
block materials and finalise your work on the assignments. If this is not your
preferred study method you will need to make appropriate adjustments when
you study the various parts of the block. Please note that the study hours in
Table 1 are given as guidelines only. You may need more time for some
parts, and less for others.

Tutor-marked assignment TMA T215 02
Tutor-marked assignment TMA T215 02
The weighting of this assignment is 15% of the continuous assessment.
You must ensure that your TMA is received by your tutor, or that you have
received a submission receipt, no later than 12 noon (UK local time) on the
cut-off date: 11 December 2014.
This module uses the online TMA/EMA service for submission of TMAs. To
submit your TMA, please go to your StudentHome page and follow the
link(s) provided. If you are unable to use the online TMA/EMA service then
you may, with your tutor’s permission, submit your assignment by post.
However, you are strongly encouraged to use the online TMA/EMA service
and you must obtain your tutor’s permission before submitting through the
postal system.
For this module, you should submit your TMAs in doc, docx or rtf file
formats. However, for TMAs that contain equations or diagrams, the
converter that some tutors will need to use to be able to read docx files can
cause detail, such as symbols, to be lost. Please, therefore, only submit docx
files with prior agreement with your tutor. You should also be aware that
rtf files may be much larger than equivalent doc files and diagrams
may not translate well, so use rtf only as a last resort.
You will be notified once your TMA has been marked. You can then
download it to view your tutor’s comments.
If you foresee any difficulty with submitting your assignment on time then
you should contact your tutor well in advance of the cut-off date.
For further information about policy, procedure and general submission of
assignments please refer to the Assessment Handbook, which can also be
accessed via your StudentHome page and from the T215 website.
Plagiarism: a reminder
Part 7 of Block 1 discusses plagiarism and shows you how to avoid it by
giving appropriate references when you use other people’s words. This short
section is intended to remind you what plagiarism is and to reiterate that it is
unacceptable in your TMAs.
Plagiarism is a form of cheating. It is the act of taking someone else’s work
and passing it off as your own (the term is derived from Latin words
meaning ‘plunder’ and ‘kidnap’). Quoting extracts – even those as short as
phrases or single sentences – from another author (including authors of T215
module materials) without saying that you are doing so is plagiarism. So is
lightly rephrasing another author’s words.
Plagiarism is not acceptable in any written material, including TMAs,
because you are in effect taking someone else’s work and passing it off as
your own.
For the most part, therefore, you should take care to express things in your
own way (this is sometimes referred to as ‘using your own words’) in your
TMAs. This will avoid plagiarism and show that you have understood the
9
Block 2 Companion 2014J
material you are writing about. On occasions you may want to use someone
else’s words, in which case you must indicate that you have done so by both
placing their words in quotation marks in the text and giving a full
reference. Do not use quotations too heavily, however, because a TMA
consisting of quotations from other authors, even if fully referenced, does
not show that you have understood the ideas you are writing about.
For more information about what constitutes plagiarism or cheating you
should refer to the online Assessment Handbook, which you can access
either from StudentHome or from the Assessment support page of the T215
module website.
Learning outcomes
This assignment enables you to demonstrate your progress with the following
module outcomes: KU1, KU2, KU3, C1, C2, KS1, KS3, P1, P2.
Question 1: critical evaluation
This question carries 15% of the assignment marks.
This question refers to Short Report C, which was written in response to
exactly the same brief as were Short Reports A and B in Part 8 of Block 2
(see Section 3), and at about the same time. You will find Short Report C in
a box after Question 4 of this TMA.
Carry out a critical evaluation of the structure of Short Report C. That is,
evaluate the report against ‘Is the structure appropriate for the audience,
purpose and medium?’ Use the checklist introduced on pp. 218–19 of
Block 2, and justify all the statements you make about the appropriateness of
the structure.
10
Tutor-marked assignment TMA T215 02
Question 2: short report
This question carries 70% of the assignment marks.
Imagine that you work for a small ICT consultancy company based in the
UK. Your company sends out an annual mailing to its clients and potential
clients, and this mailing always includes a short report. This report is about a
different technology each year. The purpose of these reports is to help the
recipients to keep abreast of some new development in ICT. The reports are
always well researched and balanced; there is no marketing ‘hype’ in them.
This year your company’s Chief Executive Officer (CEO) has decided that
the short report will be about 4G in the UK. The report is to be entitled ‘4G
and its current state of play in the UK’ and you have been asked to write it.
Your brief is that the report must be divided into five sections with the
following titles, which define the expected content. The first section is to
function as an introduction.
.
What is 4G?
.
Differences between 4G and 3G
.
Some technical details about 4G
.
An update on 4G in the UK
.
In conclusion
The mailing will go to senior managers in a wide range of businesses in the
UK. Some of these managers will have a technological background, and the
section entitled ‘Some technical details about 4G’ is intended for them.
Other recipients of the report are expected to skip over this section so the
other sections should focus on providing a broader overview rather than
detailed technical descriptions.
Your CEO has asked you to write about 750 words, with a strict maximum
of 800.
Write this report.
As well as drawing on appropriate material from Block 2, you should carry
out some research on the Web to ensure that your report is up to date. Do
not spend too long on this, however, as most of what you need is in the
block materials.
You should draw on what Part 7 of Block 2 has to say about writing short
reports. Be sure to provide a reference list if you quote or cite anything.
You are strongly advised to critically evaluate and improve your short report
before you submit it, as described in Part 8 of Block 2.
Do not exceed the limit of 800 words. Please state the total number of words
you have used at the end of your short report.
See also ‘Notes relating to Question 2’ near the end of this TMA.
11
Block 2 Companion 2014J
Question 3: underpinning for short report
This question carries 5% of the assignment marks.
In order to answer Question 2 you should have unpacked the criterion ‘Does
the report meet the brief – exactly?’ into a checklist of sub-questions. An
example for a different short report is given on page 216 of Block 2.
Submit your checklist for your report as your answer to this question.
Question 4: collaboration
This question carries 10% of the assignment marks.
In Block 3 you will be working as part of a small group of students, using a
discussion forum to help you carry out a group project which will involve
contributing material to a wiki and building a website. As you will probably
appreciate, working as part of a group presents particular challenges, but it
can be made easier by the group agreeing and also adhering to some simple
ground rules. This question asks you to work within your group’s discussion
forum to discuss and agree a set of ground rules covering the following
headings.
1 Expected levels of communication including:
◦
◦
how often and when people log into the wiki and discussion
forum
an agreed time frame for responding to contributions.
2 Managing the group work including:
◦
◦
◦
◦
how you will make decisions as a group
whether you want a leader and other managerial roles
what strategy you will adopt for coping when people are
unavailable
how you will deal with unexpected problems.
You may well find other rules useful but be mindful that this activity is
really to get you working together as a group for future activities, and so
your agreement should be reasonable and above all achievable.
When discussing and agreeing your ground rules, bear in mind that a twoweek study break occurs after the first week of Block 3 and you will need to
take this into account in your planning.
The output from this activity must be a set of agreed ground rules copied
into the ‘Ground rules’ section of the ‘Block 2 Collaboration’ page of the
wiki. In addition each member of the group should add their name to the
‘Group members’ section and give an indication of any periods during
Block 3 (13 December to 5 February) when they are likely to be unavailable
(for example, due to holidays). It is important that each person contributes
some material to the wiki ‘Block 2 Collaboration’ page, in order to gain
practice in using the wiki, as preparation for Block 3. All members of the
group are required to paste a copy of the ground rules and the list of names
and dates into their TMA.
12
Tutor-marked assignment TMA T215 02
Marks will be awarded for:
(a) the quality and appropriateness of your group’s list of ground rules as
evidenced in the material you have copied into your TMA
document (3 marks)
(b) your individual input to the discussion forum in terms of your
participation over the collaborative period, your contribution of fresh,
relevant ideas, your comments on the ideas of others and your degree of
support to the group. (7 marks)
All members of your group who contribute adequately will receive the same
mark for part (a) (the others will receive 0), but marks for part (b) will be
individual.
Short Report C (610 words)
Developments in Network Addressing
This is a short report that will be giving a brief explanation of IPV4 while
encapsulating any problems that there are with this technology. IPV6 will
be briefly discussed with a brief description outlining the migration from
IPV4 to IPV6. Finally any issues relating to this migration that may affect
the network user will be highlighted followed by a short summary.
IPv4
IPV4 (Internet Protocol Version 4) ‘is the fourth iteration of the Internet
Protocol (IP) and it is the first version of the protocol to be widely
deployed’ [2]. As a consequence to its age it is now rapidly running out
of IP addresses so consequently there are not enough addresses for
each person on the planet to have their own unique address. IPV4 has
approximately ‘4.3 Billion addresses’ [1] while there are over 6 billion
people today. There are not enough IP addresses for the people let
alone the plethora of internet ready devices and nodes at hand in
today’s world.
Currently IPV4 is managing this problem with the use of IP address
sharing facility such as NAT (Network Address Translation). This
technology currently eases the burden of having to assign every node
on the World Wide Web its own unique address. This is done by
allocating IP addresses to private networks through the use of a router.
The router stores all of the addresses within the private network then
forwards mail and internet to it. However, the router only shows up as
one IP address on the WWW leaving the IP addresses to be used again
on other private networks, As long as there is not another node within
the network with the same address there are not any problems caused..
IPv6 and How It Addresses IPv4’s Constraints
IPV6 (Internet Protocol Version 6) has several ways to overcome the
constraints of the older IPV4. Firstly there is an overabundance of
unique 128bit addresses, approximately 2128 unique addresses [1]
compared to IPV4 with approximately 232 individual 32bit addresses.
Each computer user, node and digital device on the planet will have a
13
Block 2 Companion 2014J
surplus of possible addresses to choose from. IPV6 will also be more
secure than its predecessor.Security is another of the most worried
about issues; no one wants to use a technology that is not secure
enough for their most confidential files. With the abundance of IP
addresses IPV6 is more secure. One of the reasons for this is there will
be no need for a Public key that all the nodes in a private network
sending information over the Internet will need to share.
Issues Relating To the Migration of IPv4 to IPv6 That Could
Affectthe Network user
There seems to be plenty of nervous people regarding IPV6 as it is in
the early stages of development. om IPV4 to IPV6. These include
Microsoft with the Windows Vista Operating system and Apple. So this
huge transition does seem to be inevitable.
In summary, the change from IPV4 to IPV6 is a necessity through the
lack of addresses afforded by IPV4; however this is not going to be an
overnight experience. Instead it will happen over the next few years
maybe even continuing as long as the foreseeable future. This will be a
positive move for the network consumers as the deluge of new
addresses will allow every internet ready electronic device to have its
own unique address. The newer version will consequently be a more
secure environment with vastly less errors occurring.

Tutor-marked assignment TMA T215 02
Notes relating to Question 2
In this question you need to ‘role play’ – that is, you need to write a report
that not only meets the brief but also suits the specified audience and
purpose.
Criteria for marking
Your report will be assessed against the criteria listed below. They are the
ones you met in Section 6 of Block 1, Part 7 and again in Section 3 of
Block 2, Part 8.
For the criterion relating to factual accuracy, your tutor will also take into
consideration the extent to which your report demonstrates understanding of
the topic.
1 Does the report meet the brief – exactly?
2 Is the content factually accurate?
3 Is the structure appropriate for the audience, purpose and medium?
4 Is the style appropriate for the audience, purpose and medium?
5 Is the technical level appropriate for the audience, purpose and medium?
6 Is the English correct?
Two-thirds of the available marks are for the first two criteria, and one-third
for the remaining four.
As with Question 2 in TMA 01, your tutor will award one of the grades
‘excellent (E)’, ‘good (G)’, ‘moderate (M)’, ‘weak (W)’, ‘borderline fail (B)’
and ‘fail (F)’ to each of the criteria listed above. Your grades will be
converted into a total mark for the question by means of a spreadsheet that
the T215 team will supply to tutors.
Counting the number of words used
Your total of the number of words you have used in Question 2 should
include:
.
all headings – including sub-headings, table headings and figure captions
.
any items you put in lists – except a reference list
.
any footnotes
.
any quotations you make from other sources.
You may exclude:
.
a reference list
.
text within figures
.
text within tables.
Please note, however, that if you have put text into a table simply to reduce
the word count, rather than because a table is the most appropriate means of
presenting the information, your tutor will adjust your word total upwards by
an appropriate amount.
