Do you remember using the Internet back when you had to dial in using a modem. If you are unlucky enough to still be using dial-up Internet access, I feel for you. The internet is a growing and dynamic entity and everyone will have broadband sooner or later.
Naturally companies try to offer access to internet in growing number of ways. Assuming the user has the correct hardware, a wi-fi account, and is in range of the transmitters, the service allows the user to connect to the internet at broadband speeds without the use of cables. Users can log on to the internet at these hotspots provided they have an account with the broadband supplier and the necessary wireless equipment, such as a wireless laptop or broadband-enabled mobile phone.
An extra phone is the only way to get calls that cannot be received due to the dial up connection. Fixed line operators are now incorporating wireless with their traditional phone services providing ease of having one device and one bill for both mobile and fixed line calls. You can take it out of your phone bill.
Broadband phone actually uses voice over internet protocol (VoIP) to carry phone calls through the internet. There are also a number of companies that has VoIP as a free service.
Digital Subscriber Lines, or DSL uses the existing customer phone lines to provide internet or intranet access to businesses and homes using high-speed broadband technology of varying levels. But even with all the technology that has gone into the making of the Internet, there seems to be more to be expected than has been seen. It’s easy to understand why; the technology industry defines it in different ways as well.
Just be sure you do not choose an ISDN line (because it is getting obsolete) or power line (because the technology is not mature, and it will be some years before the bugs are ironed out). The cheapest broadband deals allow for such technology to reach our homes for less than $10 per month.
Ok, on to the two major broadband access methods, cable and DSL. There is cable access, DSL access, satellite access. Although cable broadband internet is a whole lot faster than dial-up, I usually experience a slight delay when opening a webpage.
Perhaps most people do not notice the latency associated with cable internet, but it got my attention right away. So are cable television modems, which have similar speeds. Approximately 4 million people in the UK use ADSL with an extra 2 million using a cable connection, meaning 6 million people in the UK have an always-on internet connection.
The fact is that anything less than the speed supplied by a broadband cable has become inadequate for today’s internet users.
However it has emerged that broadband providers touting such products are not revealing the full story to their customers. The key will be for broadband providers to develop the services that broadband allows for, and to deliver them to as many households as possible. High-speed Internet services are growing in popularity because intense competition from broadband providers is continually driving the product exposure in the marketplace to new highs, and prices to new lows.
Connecting to the Internet for the first time in your home or office is as easy as securing a fixed telephone line (which you probably already have) and signing up to one of the dozens of Broadband Providers, like AOL and others.
Bummer indeed, but you still have broadband Direct PC by satellite and it seems to make it through those clouds and so you can surf the NOAA website and get the latest results or watch video streams of the local TV station right. Broadband Internet by Satellite is about the coolest invention in the World and indeed it has helped the unconnected become connected even if they live in the middle of nowhere. Did you know you can get a special satellite antenna hooked up on your motor home or recreational vehicle that will enable you to get the Internet anywhere in North America.
So they are bundling broadband with other products, such as home phone, digital television and mobile. The acronym is used to describe services which broadcast on-demand television programming to consumers, delivered via a broadband connection on normal telephone line to TV screens. Broadband television is a means of providing TV programs via the Internet.
Broadband Television is being hailed as the biggest change in the way we watch television since it was first invented.
* What is broadband?
In the internet world, broadband refers to the process of sending and receiving information at very high speeds through a connection that is always on. With broadband access there is always a corresponding usage fee.
Broadband access also means that you can surf to any website you want faster than with a dial-up process, as web pages load more quickly. Broadband internet can give you the advantage in accessing better quality multimedia files like music and movies. Downloading programs, files, and email attachments with broadband can be done in minutes instead of hours.
* What are the different types of broadband?
There are different types of broadband internet access available but they depend on the location of the subscriber. The most commonly used form of broadband access is the ADSL or asymmetric digital subscriber line. Other types of broadband access are cable modem, satellite, and wireless.
* What is DSL?
DSL stands for Digital Subscriber Line, which refers to the kind of technology that uses ordinary phone lines to send and receive information over the internet at higher frequency than normal phone usage. A DSL connection can handle both the data and the voice signals at the same time. Therefore your phone service is not interrupted when you use the internet.
DSL connection speeds depend on the distance between the subscriber and the provider. DSL technologies have two major types: ADSL internet access requires a fast downstream connection but slow upstream connection, and Symmetric DSL requires high speed connections in both directions.
* What is cable?
A cable is used in broadband services and refers to the transfer of internet access to subscribers by cable television. Usually, a cable is made up of bundles of different optical fibers that can carry larger amounts of data than telephone line over long distances without affecting signal frequencies.
* What are ADSL, IDSL, HDSL, and SDSL?
ADSL stands for Asymmetric Digital Subscriber Line, which has a data rate that ranges from 544 kbps up to 6.1 Mbps in downstream basis, while in upstream basis it goes from about 16 up to 640 Kbps. The distance limit of ADSL for 1.544 Mbps is about 18,000 feet, for 2.048 Mbps is 16,000 feet, for 6.312 is 12,000 feet, and for 8.448 is 9,000 feet. Normally, ADSL is used for internet access, downloading music and video, and local area networking.
IDSL or ISDN Digital Subscriber Line is somewhat an application of a wrong name of DSL modem since DSL is familiar to ISDN information rate and services that to about 144 Kbps. IDSL with its symmetric function is best when traveling up to 6 miles; however, IDSL is not supplied by ADSL providers. With similarity to ISDN, the data increases to 144 kbps by sing control channels.
HDSL or High bit-rate Digital Subscriber Line is the first version of DSL that will be used for wideband transmission within the business place and between communication providers and subscribers. The main feature of HDSL is its symmetrical function, in which the same quantity of bandwidth is accessible in both directions.
SDSL or Symmetric Digital Subscriber Line is the same as HDSL; however, it only has a single line that carries 1.544 Mbps in the U.S. and Canada or 2.048 Mbps in Europe, that flow in each direction on the duplex line.
(NC)—We are in the information age dominated by an on-demand knowledge society. Australia is one of the most connected countries in the world and the Internet has become so central to our lives that many people can’t do their work or stay in touch without it.
In short, today’s world demands high-speed Internet access.
And the demand for speed is growing as the Internet becomes an essential part of modern life and new bandwidth-hungry services, applications and devices are rolled out.
But what if you’re among the more than 7.5 million Australians in rural and remote communities who don’t have cable or DSL high-speed broadband access? Typically, these areas of the country have been underserved by the simple fact that the economics of a land-based system will never justify mass deployment.
Fortunately, there is a solution for many of these remote residents – a high-speed satellite Internet service offered by Bell ExpressVu’s DirecPC. Essentially, the system uses the same Bell ExpressVu satellite dish as the Bell ExpressVu TV service, but works independently from the satellite receiver to deliver data to your computer.
How fast is satellite Internet? DirecPC features download speeds of up to 400 kbps – that’s up to seven times faster than a traditional 56k modem.
In every day terms, that means users can download a 4MB audio file in 60-70 seconds compared with over 19 minutes using a 56K modem. Or download a 1MB video file in a little over 16 seconds compared with almost 5 minutes using a 56K modem.
It’s a broadband Internet access service that is always on and is available to anyone, anywhere in Australia with a phone line and a local Internet Service Provider.
Increasingly, high-speed Internet is becoming a must-have service. According to Australia’s National Broadband Task Force, the vast majority of Australians are going to require high-speed Internet access to use new online services from governments and businesses that are increasingly placing information and products on secure Web sites. All aspects of our society are being altered by the availability of the Internet to the point that e-business and e-learning are seen by many as crucial to the development of our economy.
Without high-speed access, the benefits of these new services are generally restricted to Australians living in the largest urban areas of the country. DirecPC satellite, however, levels the playing field for those living in remote or rural areas.
Satellites have been orbiting the earth for several decades now, and are constantly contributing to the evolution of global communication.
Satellite cell phones have made it possible for people to make phone calls from anywhere in the world, no matter how remote their location, and have been extremely useful in coordination of many activities ranging from scientific exploration to military operations.
Portable satellite radio is another important technology that has emerged in recent years, allowing users to subscribe to and access radio channels from around the world for either entertainment or informational purposes.
One small problem with satellite communication technology, however, is the sheer distance involved in communicating with orbiting satellites, which can cause a slight delay in transmission time. This, of course, is of no consequence to satellite radio, but it can be a slight problem for two-way communication services such as broadband and phone.
The only way to reduce the time delay involved in satellite transmission is to use lower orbits for satellites, thus reducing the distance involved in transmission. Lower orbits are already being used for some purposes, but there are many challenges that must be overcome in order to make such a transition.
Advancements in satellite technology have been plentiful in the past few years, and more are expected in the future. It will be very interesting to watch the development of this evolving technology over the coming years and beyond.
