China outpaces India in internet access, smartphone ownership

A majority of Europeans favor taking in refugees, but most disapprove of EU’s handling of the issue

One Laptop per Child
There are different plans. Archived from the original on 5 September Open the Network Adapters subtree, right-click all devices listed there, and select Disable. However, HDDs have a significantly lower cost. What this means is you now have the ability to watch TV on your laptop, without signing up to any bundled package, without cable and satellite, and without paying high cost to watch whatever is of interest.

The Miskito community is embracing the XO laptops as a meaningful tool for its children's future. Thanks to the Zamora Teran Foundation , every child and teacher in the community is learning together with their XOs. The first activity the students learned was the Record activity , to take videos and photos. A report on their work was published in the regional newspaper. Students of all ages have been using their laptops at home, and after school.

The younger students help one another with their work, and share work with their parents. Bluefields is a port city with a broad bay, and the community spends much of its time outside. A sunlight-readable screen is important! And in , every child on the legendary volcanic island of Ometepe received a laptop. They are also learning how to use and maintain their machines with their own laptop hospital.

This class received some of the earliest laptops, thanks to a donation. Since then, many international educators have come to work with and learn from Madagascar classrooms. Classrooms were actively engaged in the idea of adopting OLPC. This class arranged themselves so they were facing one another while working.

Many students used the Speak activity to learn to type and to hear words spoken back to them. It reads back entered text in English and French, and can respond in a limited way. Paraguayan software developers and educators have collaboratively developed localized software and class materials that they use today. Classes incorporate XOs into many of their daily projects.

Both teacher and students are engaged in deciding what tools and activities to use. Their teachers run weekly workshops inviting other teachers to come work with their students and share new ideas.

Their favorite activities include drawing, programming in Etoys, and singing along to TamTam. One class created some new TamTam libraries to add local instruments, and they are working on their own compositions. I'm enjoying the heck outa' the convenience of my Sprint Overdrive. I even get 2 MB download in the downstairs bathroom I really think it will be a good while before wireless anything replaces wired. I've seen as little as 8ms or 9ms on cable and as high as ms on 4G WiFi.

As far as wireless routers go for connecting your other wireless devices. I have tried G, N dual band N, both 2. I just got the Sprint Overdrive about a month ago and I love it. I had to pay for the Overdrive because it's a router and allows you to connect up to 5 other connections. We are very inexpensive.

We are not in every area yet, but we will be. Give us a call if you are interested. I will let you know if we are in your area. Thanks for your response. I buy a data package from my cellphone company and stick my sim card I have an extra sim into the usb modem and that connects to a laptop it looks like a memory stick ie the usb modem. It works like a charm and I'm not stuck to any contracts. I buy bandwith as I need it. This summer I went and visited relatives in Pennsylvania and needed internet for work.

I found a company called wifirents. It was really easy. If you want to connect to wireless anywhre at anytime, go to staples and ask about it. There is a plan for wireless hwere ever you go!! There are different plans. I don't have it but I just looked at it a couple of days ago!! There are different plans available!!! If you have a Blackberry, you can use the Blackberry tether app from TetherBridge http: For only a small ont-time fee, it allows your laptop to connect to the internet by sharing your Blackberry data plan for the lifetime of your Blackberry.

Works great and extremely cost effective. Shopping for a new car this weekend? You are posting a reply to: Need laptop wireless internet service that can go anywhere.. Track this discussion and email me when there are updates. And while LANs are an important form of Internet access, this raises the question of how and at what data rate the LAN itself is connected to the rest of the global Internet. The technologies described below are used to make these connections. The term broadband includes a broad range of technologies, all of which provide higher data rate access to the Internet.

The following technologies use wires or cables in contrast to wireless broadband described later. Dial-up Internet access uses a modem and a phone call placed over the public switched telephone network PSTN to connect to a pool of modems operated by an ISP. The modem converts a computer's digital signal into an analog signal that travels over a phone line's local loop until it reaches a telephone company's switching facilities or central office CO where it is switched to another phone line that connects to another modem at the remote end of the connection.

Operating on a single channel, a dial-up connection monopolizes the phone line and is one of the slowest methods of accessing the Internet. Dial-up is often the only form of Internet access available in rural areas as it requires no new infrastructure beyond the already existing telephone network, to connect to the Internet. Multilink dial-up provides increased bandwidth by channel bonding multiple dial-up connections and accessing them as a single data channel.

This inverse multiplexing option was briefly popular with some high-end users before ISDN, DSL and other technologies became available. Diamond and other vendors created special modems to support multilinking.

Integrated Services Digital Network ISDN is a switched telephone service capable of transporting voice and digital data, as well as one of the oldest Internet access methods. ISDN has been used for voice, video conferencing, and broadband data applications. Its use peaked in the late s before the availability of DSL and cable modem technologies. Leased lines are dedicated lines used primarily by ISPs, business, and other large enterprises to connect LANs and campus networks to the Internet using the existing infrastructure of the public telephone network or other providers.

Delivered using wire, optical fiber , and radio , leased lines are used to provide Internet access directly as well as the building blocks from which several other forms of Internet access are created. A T1 line carries 24 voice or data channels 24 DS0s , so customers may use some channels for data and others for voice traffic or use all 24 channels for clear channel data. T-carrier lines require special termination equipment that may be separate from or integrated into a router or switch and which may be purchased or leased from an ISP.

At lower transmission rates data can also be transferred via an electrical interface. Thus an OC-3c will carry three OC-1 The "c" at the end of the OC labels stands for "concatenated" and indicates a single data stream rather than several multiplexed data streams. Cable Internet provides access using a cable modem on hybrid fiber coaxial wiring originally developed to carry television signals.

Either fiber-optic or coaxial copper cable may connect a node to a customer's location at a connection known as a cable drop. In a cable modem termination system , all nodes for cable subscribers in a neighborhood connect to a cable company's central office, known as the "head end.

Broadband cable access tends to service fewer business customers because existing television cable networks tend to service residential buildings and commercial buildings do not always include wiring for coaxial cable networks. Cable networks regularly provide encryption schemes for data traveling to and from customers, but these schemes may be thwarted. Unlike dial-up, DSL can operate using a single phone line without preventing normal use of the telephone line for voice phone calls.

DSL uses the high frequencies, while the low audible frequencies of the line are left free for regular telephone communication. DSL originally stood for "digital subscriber loop". In ADSL, the data throughput in the upstream direction, i. However, the maximum data rate is achieved at a range of about meters and performance degrades as distance and loop attenuation increases. The differences between the methods have mostly to do with just how close to the end user the delivery on fiber comes.

All of these delivery methods are similar to hybrid fiber-coaxial HFC systems used to provide cable Internet access. The use of optical fiber offers much higher data rates over relatively longer distances. Most high-capacity Internet and cable television backbones already use fiber optic technology, with data switched to other technologies DSL, cable, POTS for final delivery to customers. Australia began rolling out its National Broadband Network across the country using fiber-optic cables to 93 percent of Australian homes, schools, and businesses.

Similar efforts are underway in Italy, Canada, India, and many other countries see Fiber to the premises by country. Power-line Internet , also known as Broadband over power lines BPL , carries Internet data on a conductor that is also used for electric power transmission. Because these systems use parts of the radio spectrum allocated to other over-the-air communication services, interference between the services is a limiting factor in the introduction of power-line Internet systems.

The IEEE P standard specifies that all power-line protocols must detect existing usage and avoid interfering with it. Power-line Internet has developed faster in Europe than in the U. Data signals cannot pass through the step-down transformers used and so a repeater must be installed on each transformer. In Europe, it is more common for a somewhat larger transformer to service larger clusters of from 10 to houses.

Thus a typical U. Asynchronous Transfer Mode ATM and Frame Relay are wide-area networking standards that can be used to provide Internet access directly or as building blocks of other access technologies. For example, many DSL implementations use an ATM layer over the low-level bitstream layer to enable a number of different technologies over the same link. Wireless broadband is used to provide both fixed and mobile Internet access with the following technologies.

Satellite Internet access provides fixed, portable, and mobile Internet access. In the northern hemisphere, satellite antenna dishes require a clear line of sight to the southern sky, due to the equatorial position of all geostationary satellites.

In the southern hemisphere, this situation is reversed, and dishes are pointed north. When other switching and routing delays are added and the delays are doubled to allow for a full round-trip transmission, the total delay can be 0. This latency is large when compared to other forms of Internet access with typical latencies that range from 0. Long latencies negatively affect some applications that require real-time response, particularly online games, voice over IP , and remote control devices.

GEO satellites do not cover the Earth's polar regions. Lower altitudes allow lower latencies and make real-time interactive Internet applications more feasible. LEO systems include Globalstar and Iridium. Mobile broadband is the marketing term for wireless Internet access delivered through mobile phone towers to computers, mobile phones called "cell phones" in North America and South Africa, and "hand phones" in Asia , and other digital devices using portable modems.

Some mobile services allow more than one device to be connected to the Internet using a single cellular connection using a process called tethering. The modem may be built into laptop computers, tablets, mobile phones, and other devices, added to some devices using PC cards , USB modems , and USB sticks or dongles , or separate wireless modems can be used. New mobile phone technology and infrastructure is introduced periodically and generally involves a change in the fundamental nature of the service, non-backwards-compatible transmission technology, higher peak data rates, new frequency bands, wider channel frequency bandwidth in Hertz becomes available.

These transitions are referred to as generations. The first mobile data services became available during the second generation 2G. The download to the user and upload to the Internet data rates given above are peak or maximum rates and end users will typically experience lower data rates. WiMAX was originally developed to deliver fixed wireless service with wireless mobility added in By focusing the radio signal using a directional antenna where allowed by regulations , In addition, compared to hard-wired connectivity, there are security risks unless robust security protocols are enabled ; data rates are usually slower 2 to 50 times slower ; and the network can be less stable, due to interference from other wireless devices and networks, weather and line-of-sight problems.

With the increasing popularity of unrelated consumer devices operating on the same 2. If the service provider holds the necessary spectrum license, it could also reconfigure various brands of off the shelf Wi-Fi hardware to operate on its own band instead of the crowded unlicensed ones.

Using higher frequencies carries various advantages:. There are a number of companies that provide this service. In some regions, notably in rural areas, the length of the copper lines makes it difficult for network operators to provide high bandwidth services.

Deploying multiple adjacent Wi-Fi access points is sometimes used to create city-wide wireless networks. Grassroots efforts have also led to wireless community networks widely deployed at numerous countries, both developing and developed ones. Rural wireless-ISP installations are typically not commercial in nature and are instead a patchwork of systems built up by hobbyists mounting antennas on radio masts and towers , agricultural storage silos , very tall trees, or whatever other tall objects are available.

Where radio spectrum regulation is not community-friendly, the channels are crowded or when equipment can not be afforded by local residents, free-space optical communication can also be deployed in a similar manner for point to point transmission in air rather than in fiber optic cable. Packet radio connects computers or whole networks operated by radio amateurs with the option to access the Internet.

Note that as per the regulatory rules outlined in the HAM license, Internet access and e-mail should be strictly related to the activities of hardware amateurs. The term, a tongue-in-cheek play on net work as in Internet or Ethernet , refers to the wearing of sneakers as the transport mechanism for the data. For those who do not have access to or can not afford broadband at home, downloading large files and disseminating information is done by transmission through workplace or library networks, taken home and shared with neighbors by sneakernet.

There are various decentralized, delay tolerant peer to peer applications which aim to fully automate this using any available interface, including both wireless Bluetooth, Wi-Fi mesh, P2P or hotspots and physically connected ones USB storage, ethernet, etc. Sneakernets may also be used in tandem with computer network data transfer to increase data security or overall throughput for big data use cases. Innovation continues in the area to this day, for example AWS has recently announced Snowball, and bulk data processing is also done in a similar fashion by many research institutes and government agencies.

Internet access is limited by the relation between pricing and available resources to spend. Current Internet access prices exceed the available resources by large in many countries. Dial-up users pay the costs for making local or long distance phone calls, usually pay a monthly subscription fee, and may be subject to additional per minute or traffic based charges, and connect time limits by their ISP.

Though less common today than in the past, some dial-up access is offered for "free" in return for watching banner ads as part of the dial-up service. Some Wireless community networks continue the tradition of providing free Internet access. Fixed broadband Internet access is often sold under an "unlimited" or flat rate pricing model, with price determined by the maximum data rate chosen by the customer, rather than a per minute or traffic based charge.

Per minute and traffic based charges and traffic caps are common for mobile broadband Internet access. Internet services like Facebook , Wikipedia and Google have built special programs to partner with mobile network operators MNO to introduce zero-rating the cost for their data volumes as a means to provide their service more broadly into developing markets.

With increased consumer demand for streaming content such as video on demand and peer-to-peer file sharing, demand for bandwidth has increased rapidly and for some ISPs the flat rate pricing model may become unsustainable.

Some ISPs estimate that a small number of their users consume a disproportionate portion of the total bandwidth. In response some ISPs are considering, are experimenting with, or have implemented combinations of traffic based pricing, time of day or "peak" and "off peak" pricing, and bandwidth or traffic caps.

Others claim that because the marginal cost of extra bandwidth is very small with 80 to 90 percent of the costs fixed regardless of usage level, that such steps are unnecessary or motivated by concerns other than the cost of delivering bandwidth to the end user. In Nashville exceeding the Gbyte cap mandates a temporary purchase of 50 Gbytes of additional data. Despite its tremendous growth, Internet access is not distributed equally within or between countries.

The gap between people with Internet access and those without is one of many aspects of the digital divide. Government policies play a tremendous role in bringing Internet access to or limiting access for underserved groups, regions, and countries.

For example, in Pakistan, which is pursuing an aggressive IT policy aimed at boosting its drive for economic modernization, the number of Internet users grew from , 0. Access to computers is a dominant factor in determining the level of Internet access. Internet access has changed the way in which many people think and has become an integral part of peoples economic, political, and social lives. Access to the Internet grew from an estimated 10 million people in , to almost 40 million in , to million in , and to 2.

There were roughly 0. In developing countries mobile broadband is often the only access method available. Traditionally the divide has been measured in terms of the existing numbers of subscriptions and digital devices "have and have-not of subscriptions".

For example, "the massive diffusion of narrow-band Internet and mobile phones during the late s" increased digital inequality, as well as "the initial introduction of broadband DSL and cable modems during — increased levels of inequality". As shown by the Figure, during the mids, communication capacity was more unequally distributed than during the late s, when only fixed-line phones existed.

The most recent increase in digital equality stems from the massive diffusion of the latest digital innovations i.
