2. Introduction
 Public Wireless Network
• Service provided by municipality connecting municipal
buildings and services to give broadband access to the
entire population

3. Introduction

4. Advantages
 Lower costs: because it’s a communitarian connection shared
by everyone
• Infrastructure: installation of the network as it is in a
municipality is not a big investment.
• VoIP services: within metropolitan environment, allowing
to substitute traditional analog telephone lines and RSDI,
eliminating the common expense of them.
 Mobility: users can keep connected while it’s moving within a
geographical area.
• Connectivity: wireless networks allow to connect remote
devices easily to distances such different as from a few
meters to kilometers.
• Financing: it can be public or private or a combination of
both

5. Disadvantages
Security
 Users control: from the municipality to
those who access the network
 Network congestion: in highly populated places or with
many users in transit which will lead to a very large
distribution of available broadband.
 Coverage: distant places from access points where the
signal can get there with less power and get coverage will
be lost.

6. Applications
Mobility Applications Citizens applications
Traffic and access control Free public access
Video surveillance Residential internet access
Digital traffic advertisement Commercial and touristic
information and promotion
Working classmen mobility Educative collaboration
Emergency and sanitary
assistance support
Free internet access in
municipality places

7. Applications
Municipality applications Other applications
Interconnection between
municipals places
Measures for telemetry and
contaminations levels
Municipal intranet access Transportation
interconnection
E-administration Traffic light control
Access to application for
municipal management
Smart applications for public
transportation

improve energetic efficiency

8. Network structure
 Backbone: main network that connects
different population cores, usually through
WiMax or optic fiber technology
 Network access: starting from backbone
it extends by network nodes towards end
users. In this case, WiFi technology is use
 Acccess points: devices necessary to
connect users to municipal network

9. State of play in Argentina

11. State of play in Argentina
“Argentina conectada”
 “Argentina conectada” it’s a state policy which main objective is to
generate a digital platform of infrastructure and services for
government and citizen bonding.
 Infrastructure and equipment for connectivity: set up a safe
optic fiber network, strategic and sovereign, staring with zones
without infrastructure and federalizing quality, prices and content
 Government services and cultural content: technology for a
better management and quality in communications between different
government areas. Encourage in development of social valor content
 Digital inclusion: implementation of spaces for access to new
technologies that allow to develop skills and motorizes tools of
communities development.
 The company ARSAT SA, of state actives, has the function of
implement projects in its different stages in an inclusive and federal
way in function of public sector requirements (cooperatives, local
operators, small companies) , social and cultural movement,
productive, scientific and technological sector.

12.  Through full deployment of optical fiber federal network,
the objective is to reach 97% of population for 2015. The
3% left will cover it’s necessities through satellite service.

Arsat in Argentinian State policies
“Argentina Conectada”
 Through a public investment of $8.000 million, "Argentina conectada”
Telecommunications national plan, it’s objective is to expand broadband
service and digital TV all along the country.
 ARSAT, it’s in charge of implementation of the optic fiber federal network,
and has in mind the construction of optic fiber in places where it has not
arrived yet, through a 80.000 km network.

14. State of play in Argentina
 In matter of infrastructure a federal network
of optic fiber will be develop, established as
public interests through decree number
1552/2010 that creates national plan
“Argentina conectada”
 It will impulse construction of national
infrastructure complementary of existing
communications networks (meaning,
traditional operators)
 It will be developed a first step of 10.000
kilometers of new networks, reaching 35.000
kilometers, tripling the current installed
capacity.
 Through the deployment of infrastructure
and enlargement of services offer, an impact
is achieved directly to wholesale of data
transport, that will result in a reduction of
inclusion and equality indices in the whole
country regarding accessibility, quality of
service and price
Fiber optic
Federal network

15. State of play in Argentina
 With the purpose to guarantee availability in
the entire national territory of an advances
network of telecommunications, it will be
deployed the optical fiber provincial network
to build in every province of Argentina
Republic.
 Through network deployment the goal is to
connect every city in the national territory,
allowing to interconnect the backbone and
local operators, who will be the ones to bring
residential access service.
 According to the schedule, the construction
of provincial network is divided in two stages:
 First stage was developed in 2011, covering
the construction of 13.300 kilometer of optic
fiber
 Second stage has in mind the construction of
8.600 kilometer of optic fiber

habitants
 Mayor communication system from Latin
America
 It’s developed through University of La
Punta, giving free Wi-Fi to the whole San
Luis population

21.  Similar services to those in San Luis exist in the city of Buenos
Aires, Rosario, Cordoba, etc. Besides there are ongoing project in
most of the provinces along the country

22.  In most of developed industrial countries internet access is free
and it has been like that for many years now.
 USA and South Korea are highlighted among them
 Every major city has some kind of service in public spaces.
 In USA the FCC is planning to offer free wifi in the entiry country.
For example, now a days Google already gives free access in the
neighborhood of Chelsea in New York and in some places in Sillicon
Valley
 Gowex company offers free wifi connections in many countries
around the world, availability can be checked in this map

23. Loon project (by Google)
 Project Loon is a network of balloons traveling on the edge of space,
designed to connect people in rural and remote areas, help fill coverage
gaps, and bring people back online after disasters.
 Technology: balloons float in the stratosphere, twice as high as
airplanes and the weather. They are carried around the Earth by winds
and they can be steered by rising or descending to an altitude with winds
moving in the desired direction. People connect to the balloon network
using a special Internet antenna attached to their building. The signal
bounces from balloon to balloon, then to the global Internet back on
Earth.
 How Loon connects: Each balloon can provide
connectivity to a ground area about 40 km in diameter at speeds
comparable to 3G. For balloon-to-balloon and balloon-to-ground
communications, the balloons use antennas equipped with specialized
radio frequency technology. Project Loon currently uses ISM bands
(specifically 2.4 and 5.8 GHz bands) that are available for anyone to use.

24. O3b (other 3 billion)
 12 satellites in a new constellation to provide affordable, high-
speed Internet to people in nearly 180 "under-connected"
countries, where shooted to space on 09/07/2013
 The system would cover a region between the latitudes of 45
degrees North and 45 degrees South—the entire African
continent, most of Latin America, the Middle East, southeast Asia,
Australia and the Pacific Islands.
 There are already geostationary satellites providing this type of
services, but at a prohibitive cost for many end-users. Existing
satellites generally orbit at an altitude of some 36,000 kilometres
(22,000 miles) above Earth, weigh in at a hefty four to six tonnes
each, and take much longer to bounce a signal back to Earth—
about 500 milliseconds to be exact, according to an O3b
document. The O3b satellites, built by the Franco-Italian company
Thales Alenia Space, will orbit at 8,062 km and will weigh only
650 kilogrammes (1,400 pounds) each. Investors include Internet
giant Google, cable company Liberty Global, satellite operator
SES, HSBC bank and the Development Bank of Southern Africa.
