  • Wi-Fi is one of the most ubiquitous wireless communications technologies in use today, primarily because it is easy to install, easy to use and inexpensive. Wi-Fi was originally designed as a way of extending internet connections wirelessly within an enterprise. However people soon began installing Wi-Fi Access Points at home and in public Hotspots to give convenient internet access to laptops, which ended up with Wi-Fi chips installed as standard. Today there are hundreds of millions of devices which use Wi-Fi including tablets, smart phones, TVs and set tops. There are millions of public hotspots and many hundreds of millions of home and enterprise access points. The Wi-name Fi is reserved for the IEEE 802.11 standards – so far A, B, G and N, with more on the way, and use 2.4 GHz and 5 GHz unlicensed spectrum bands, with more being considered up to 60 GHz. Wi-Fi today is managed and policed by the Wi-Fi Alliance. Wi-Fi reach varies with the power of the signal and the spectrum used, but will typically reach a few hundred feet and current generation devices will provide between 50 Mbps and a 100 Mbps shared between connected users.

  • The Wireless Internet Opportunity for Developing Countries examines the emergence and promise of proven and inexpensive technologies to bridge the connectivity gap at the root of the digital divide.
  • The promises of wireless Internet technologies have generated much interest on the part of the international-development community.
  • While in developed nations these technologies have primarily been associated with mobility applications and local area networking in homes and offices, their most intriguing application in developing nations is the deployment of low-cost broadband Internet infrastructure and lastmile distribution.

  • Wireless Internet may be a very effective and inexpensive connectivity tool, but it does not carry any magic in itself.
  • It can only be successfully deployed as demand for connectivity and bandwidth emerges in support of relevant applications for the populations served.
  • These may be supporting e-government, e-education, e-health, e-business or e-agriculture applications. But those are not easily implemented in the developing world.
  • Demand aggregation for wireless Internet connectivity around applications that make sense in support of wireless infrastructure investment is the first important challenge that the UN ICT Task Force, infoDev, and the Wireless Internet Institute wanted to explore and document.
  • The authors of this compendium have investigated dozens of field experiments around the world and selected several that exemplify some of the innovative approaches to this challenge.
  • One common characteristic of these case studies is their unconventional, often grassroots origin. Entrepreneurs from the private, public, or not-for-profit sectors have independently developed original deployment models pointing to potential solutions for the developing world.

  • This wave is washing up on our shores now—and it’s already reconfiguring the politics of spectrum access, as well as the future architecture of broadband networks. Although unlicensed spectrum is typically associated with home and coffee shop Wi-Fi, as well as with embattled community networks promoted by nonprofits and some municipalities, increasingly the leading broadband carriers are waking up to the cost-effectiveness of sharing public spectrum.

  • Whether it’s because you have made a call using a mobile phone, received a message on your pager, checked your email from a PDA or even just seen an advert related to it, we have all come across a wireless data or voice network!
  • These types of networks can be maintained over large areas, such as cities or countries, via multiple satellite systems or antenna sites looked after by an ISP. These types of systems are referred to as 2G (2nd Generation) systems.
  • Wireless networking can prove to be very useful in public places – libraries, guest houses, hotels, cafeterias, and schools are all places where one might find wireless access to the Internet.

  • This technology allows the connection of multiple networks in a metropolitan area such as different buildings in a city, which can be an alternative or backup to laying copper or fibre cabling.
  • A wireless networking system would rid of the downtime you would normally have in a wired network due to cable problems
  • Wired Equivalent Privacy is intended to stop the interception of radio frequency signals by unauthorized users and is most suitable for small networks.
  • Bluetooth is a simple type of wireless networking that allows the formation of a small network with up to eight devices being connected at once
  • Bluetooth falls under personal area networking since it is has a very short range – 30 to 300 feet.
  • The main features of Bluetooth are that unlike Infra Red, the signal is not affected by walls it uses radio technology, it is not very expensive, and has little power consumption.
