  1. 1. Broadband Internet: Projects to provide Internet broadband access for public audience, free of charge and without geographical limits 66.77 Sistemas de Comunicaciones Paperwork n 9 Group N 4: Cotelli, Andrés (86556) Munaretti, Gastón (74421) Candial, Mariano (81522)
  2. 2. Introduction  Public Wireless Network • Service provided by municipality connecting municipal buildings and services to give broadband access to the entire population
  3. 3. Introduction
  4. 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. 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.

  12. 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. State of play in Argentina
  13. 13. State of play in Argentina 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. 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. 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 Red Provincial de Fibra Óptica

  23. 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. 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.
