This document summarizes the analysis and proposed implementation of a network communication system for the Archdiocese of Beira in Mozambique. The current system lacks security, file sharing, and resource sharing. The proposed system would connect both units of the Archdiocese with fiber internet, set up an Active Directory domain, and implement file sharing, email, printing, and backup services using Windows and other standard servers and networking equipment. The new network aims to improve communication, productivity, and cost efficiency for the Archdiocese. Future work includes installing and configuring the equipment, training staff, and developing ICT policies.

3. Introduction
• The 21st century is characterized by massive
use of information and communication
technologies in almost every lines of work.
• My area of interest falls within associating
theoretical and practical studies, and want to
extend this to the use of technology in the
Archdiocese of Beira.
• The project will covered the steps of data
collection, data analysis, and proposed
implementation of the network and its
services.

4. About Archdiocese of Beira
• The Archdiocese of Beira is a religious
institution, which operates in Sofala Province.
• It has the central offices in Beira, Rua Correia
de Brito, 125.
• It was founded on September 4, 1940
• The current archbishop is Don Claudio Zuanna.
• The Archdiocese of Beira, is organized into two
major sectors - the secretariat of pastoral
coordination, and the secretariat of the
diocese.

5. Problem Description
• The activity of every organization, in the 21st
century, relies on Information and
Communication Technology for its
performance and achievement.
• There is no way an organization can operate
successfully without a well-structured
information communication system.
• Currently Archdiocese of Beira does not have
a computer network infrastructure that suits
the operations of a religious institution.

6. Problem Description(Cont)
• With lack of a computer network
infrastructure, this institution faces the problems
listed below:
– Lack of security of computer resources currently
available and connected to internet
– Lack of file sharing
– Lack of computer resources sharing, such as printers
– Vulnerability of resources connected to the Internet
in terms of virus and malware attacks
– High costs in the use of paper, and not sharing
resources
– Lack of ICT policy for that institution

7. Project Description
• The core theme of this project is to analyse,
design and implement a network
communication system for archdiocese of
Beira.
• The entire problems highlighted above must
be solved within the project.

8. Project Goal
• The goal is to create a network communication
system to improve the operations of
archdiocese of Beira.
• This will be done by structuring the network,
including all the necessary services and
components, build a portal that will change
the face of the organization by making it easy
for communication in all aspects, involving the
most remote users.

9. Current state of the network
infrastructure
• As mentioned previously the Archdiocese of
Beira is composed of two major units that are
the secretariat of pastoral coordination with
approximately 17 departments and the
Secretariat of the Archdiocese of
approximately 7 departments.

12. Common aspects to both units
• The two separate connections are a financial
burden to the archdiocese.
• The other problem is the speed of the
connection.
• Most of the time it becomes so slow that can
take up to five minutes to download a simple
web page.
• There is nobody responsible for technical
issues to ensure quality of services, particularly
in computer resources including the internet
connection.

13. Common aspects to both units
• The means used by the archdiocese (the two
units) to communicate with other parishes and
other constituents are manually written
letters, faxes, telephone communication using
land lines and mobile telephone, e-mail for
pastors and priests who have computers and
public e-mail addresses.
• Don Claudio Zuanna, revealed that he created a
domain (diocese.beira.org) in Italy before his
coming to Mozambique, to streamline the
technological needs of an institution he is going to
head.

14. User Needs
• Because we need to create a communication
system for the archdiocese, we had to first get
the organizations user’s need, which are the
following:
– User needs

15. Implementation Methodologies

16. Network connectivity
• The connection to the internet will use T1
Leased Line Connection or Fiber Optic which is
a permanent, dedicated high performance
telecommunications network connection
which can transport voice and data via a
copper or fiber optic connection between a
customer site and the ISP’s hub.
• The preferred ISP will be Movitel.

17. Domain Name and Web Hosting
• The creation of a local-Mozambican domain
name which ends with .mz is highly
recommended.
• Because the organization needs to implement
a network capable of hosting their own web
site, we recommend Movitel as the ISP for
such services since they provide services from
they own fiber connectivity with better
performance than other ISPs.

18. Network cabling
• The network will consist in two parts - wired
and wireless.
• For the wired part, the use UTP Cat6 which is
an improvement on the cat5 and cat5e is
recommended.
• It is a standard cable used in Gigabit Ethernet
network connections. This will enable the
same connectivity be used for voice in the
future.

19. Wireless Networking
• For the wireless network, the use of UniFi
Enterprise Wi-Fi System is recommended.
• UniFi Enterprise Wi-Fi System is a scalable
enterprise access point solution designed to
be easily deployed and managed.
• UniFi AP indoor models have a soft design
and can be easily mounted to a ceiling tile or
wall using the included mounting hardware.
• Standard: Wireless Indoor Access Point 2.4
GHz, 802.11b/g/n, 300 Mbps,

20. Buildings interconnectivity
• Because the two buildings are separated by a road and
the total distance between them is approximately 250
meters, we recommend the use of Ubiquiti Pico
Station M2-HP 2.4GHz Hi Power 802.11N Outdoor
Radio System.
• The PicoStationM2-HP is one of the smallest outdoor
802.11g/n access points and it's also one of the most
powerful, with up to 1,000 mW of output power.
• This omni-directional router can provide up to 8
million square feet of wireless coverage.
• It can connect to 802.11g/n devices or, for maximum
range and speed, compatible Airmax11n devices.

21. Routers
• Cisco 3900 Series Generation 2 Router is the recommended router.
• The Cisco Integrated Services Routers Generation 2 (ISR G2)
platforms are designed to enable the next phase of branch-office
evolution, providing rich-media collaboration and virtualization to
the branch office while maximizing operational cost savings.
• These routers support
– new high-capacity digital signal processors (DSPs) for future enhanced
video capabilities,
– high-powered service modules with improved availability,
– multicore CPUs,
– Gigabit Ethernet switching with Cisco Enhanced Power over Ethernet
(ePoE),
– and new energy visibility and control capabilities while enhancing
overall system performance.

22. Switches
• For this network infrastructure, we
recommend Cisco 300 Series Switches.
• Cisco 300 Series Switches deliver the ideal
combination of price, performance, and
capabilities in a solution designed specifically
for small businesses.

23. Firewalls
• For security reasons the use a Unified Threat
Management (UTM) is recommended.
• Unified Threat Management (UTM) is used to
describe network firewalls that have many
features in one box, including e-mail spam
filtering, anti-virus capability, an intrusion
detection (or prevention) system (IDS or IPS),
and World Wide Web content filtering, along
with the traditional activities of a firewall.

24. Enterprise Servers
• For servers, HP Integrity rx2800 i4 Server or its
equivalent is recommended.
• HP Integrity rx2800 i4 Server is a reliable and
secure 2U two-socket UNIX server.
• Integrity rx2800 i4 Server enables workload
consolidation and software licensing cost
savings through HP Virtual Partitions (vPars) or
Virtual Machines (VMs), while HP Insight
software and HP Integrated Lights-Out 3 (iLO
3) increase staff productivity.

33. System Services
Implementation

34. Mail Service
• In order to increase the facilities of
communications among parishes and the rest of
the world, this service must be implemented as
the domain.
• For such a solution Microsoft Exchange Server will
be used.
• Microsoft Exchange Server is a mail
server, calendaring software and contact manager
developed by Microsoft.
– It is a server program that runs on Windows Server and
is part of the Microsoft Servers line of products.
Exchange 2013 which has the following features will be
used.

35. Web Service
• The web server will be configured using
Apache Open Source package.
• Apache is generally recognized as the world's
most popular Web server (HTTP server).
• Originally designed for UNIX
environments, the Apache Web service has
been ported to Windows and other network
operating systems.

36. Print Service
• A centralized print service using a print server will
be implemented to minimize cost and
administration
• A print server is a device that connects printers to
client computers over a network.
• It accepts print jobs from the computers and
sends the jobs to the appropriate
printers, queuing the jobs locally to
accommodate the fact that work may arrive more
quickly than the printer can actually handle it.

37. DHCP Service
• Dynamic Host Configuration Protocol (DHCP) will
be the recommended protocol for IP addressing.
• Dynamic Host Configuration Protocol (DHCP) is a
network protocol that enables a server to
automatically assign an IP address to a computer
from a defined range of numbers configured for a
given network.
• For this project, DHCP in Windows Server 2012, is
recommended.

38. File Service
• File services provide the opportunity to access
data which are stored on central file servers will
be implemented.
• File Server Role of Windows Server 2012, is
recommended, for it provides a central location
on your network where you can store and share
files with users across your network.
• When users require an important file, they can
access the file on the file server instead of having
to pass the file between their separate
computers.

39. Backup and Disaster Recovery
• A Data Backup or simply Backup is the result of
copying or archiving files and folders for the
purpose of being able to restore them in case of
data loss.
• An HP Store Once 2620 iSCSI Backup (BB852A)
system will be used.
• HP StoreOnce Backup systems reduce the
amount of backup data you need to store by up
to 95%, with our scale-out architecture you can
pay as you grow to retain up to 10 petabytes of
data in a single pool.

40. Conclusion
• Implementation of this system will change the face of
the archdiocese of Beira in many ways:
– In terms of, effective communication,
– increase productivity, and
– competitiveness,
– cost reduction in bandwidth consumption,
– reusability of IT resources, and
– cost reduction on printing.
• The difficulties of communication among parishes and
archdiocese will improve because the e-mail address
will be used by all of the members of the
organization, and the file exchange will also be done
electronically, rather than printed way happening
nowadays.

41. Future Work
• This thesis has outlined all the implementation
strategies, equipment needs, budget and future works
yet to be concluded includes the following:
– Physical installation and configuration of the network
equipment
– Connection to the fiber grade
– Recruitment of staff to manage the system
– Training of staff and users
– The acquisition of various materials network otherwise
specified should be done by experts in computer networks
as well as certified providers within or outside the country.
• There should be a policy for ICT in order to settle the
terms of use of resources.
• All members of the archdiocese should be trained to
understand how the system works and do their best use
