High-Speed Internet Options

Technology being what it is these days, there is a wide range of internet options. Even in the elite category of high-speed internet, the selection can be overwhelming and it might seem like it takes a technology expert to make the right decision when choosing an internet provider. DSL should mean something to us, but in many cases it doesn't; cable modems seem like a necessity for the Comedy Channel, not the internet; and satellite broadband sounds like something recently tested by NASA. Many of us feel your pain. To that end, here is a simplified look at the wide world of high-speed internet and its three biggest players: Cable, DSL and Satellite Broadband.

First of all, high-speed or "broadband" internet is internet service which transfers information rapidly. If you've ever used dial-up internet, it is generally the step above dial-up. However, as technology has progressed over the past five years, the standard has risen along with it. Whereas broadband internet began by beating dial-up (i.e., anything greater than 56 kilobits per second), the latest accepted transmission standard for broadband is somewhere greater than 250 kbs/s and usually better than 750 kbs/s At these speeds, pictures and data can download almost instantly. The standard will likely continue to rise, but you should not settle for bandwidths below 750 or even 1000 kbs/s, also called 1 Mb. Think of it as the horsepower for your engine, or the miles per gallon for gas efficiency. It is your most important tool when shopping for an internet provider.

Just looking at the definition of high-speed or broadband internet, it is clear that dial-up is not an impressive option. DSL, on the other hand, is a feasible high-speed solution. An acronym for Digital Subscriber Line, DSL is commonly thought of as "Direct Service Line." While erroneous, it is actually mistaken with good reason, for DSL technology works with a telephone or "hard" line. Often compatible with an existing line, DSL internet uses a different frequency than your phone and typically supplies a strong bandwidth for information transfer. An obvious drawback: if the telephone line doesn't go there, DSL doesn't go there.

The same can be said for getting internet via cable. The internet will operate using the same technology that brought cable television into your home. When you hear the words cable modem tossed around, don't fret. A modem is just a box used to transmit signals: think of it as a cable box for your computer. High-speed internet using the cable system can range from good to excellent. The same rule applies: if the cable company does not service your area, you will not be able to get internet in this way.

Which leaves us at one of the key options for the rural or "off-the-grid" customer: satellite broadband. In the same way satellite tv has found its audience, satellite internet is available where no other credible options exist. Instead of a cable modem or a telephone line, your hardware will be a satellite dish. Installation will require pointing the dish without obstruction to achieve the best possible signal. Drawbacks include: trouble experienced during bad weather and a slightly higher price tag than cable or DSL. But left to choose between satellite internet and dial-up service, the decision is an easy one: go satellite and don't look back.

Is Satellite Internet the Future

Satellite internet is a new and intriguing technology that is winning over dedicated followers by droves as it makes its way into newer markets and increases its public profile. Available for already more than a few years now, this fascinating technology has finally really come into its own, with several modifications and improvements which have really raised the bar to well above the level that the average consumer will expect when ordering an internet service.

Satellite internet really has been optimized in such a way as to make it more than reliable enough to use in serious, work-related contexts on a heavy basis to accomplish pressing goals, and it is for this reason that the technology is spreading life wildfire among internet users the world over. There is just such a perfect mix of incentives and advantages that it is too difficult to resist the temptation to get this kind of a which will have you wondering why you had never heard of it before!

For starters, there could be nothing easier than having a satellite internet connection installed in your home. This, of course, goes against what many people think about satellite technologies in general: that the installation is a major pain in the neck and that it is intrusive and takes a long time, not to mention confusing. When you order your connection from a reliable provider, you will be guaranteed installation by certified professionals who know exactly what they are doing and will be in and out of your home in practically no time at all.

The average wait period to receive professional installation varies but is usually between one and two weeks (obviously homes that are very far out in the countryside and remote will need to wait longer than most others to receive installation). Once they get to your door, the professional installers will only take a few hours to mount your dish using sturdy brackets and to drill through only one wall and run coaxial cables from the dish to the wall jack (which they will have to install). After this, the installer will commission your account and verify that everything is working properly and give you a brief lesson on the hardware and how to use the connection, with all the information being very easy to digest.

From there, you pretty much have had the doors to the future opened up for you. Your satellite internet connection will give you the kinds of download speeds you had only ever dreamed of in your home, in general reaching over 3mbps. That is really extraordinary when you think about it, especially since the first satellite internet connections didn't even reach half of that capacity (which was the predicament only a few short years ago). And one other great benefit of today's satellite connections is that they are two-way rather than one-way (which was the case until just recently), so that you can upload as well as download files from the internet all via your dish, completely eliminating the need for a phone modem altogether.

VoIP stands for Voice over Internet Protocol and it is connected to other technologies that let all IP networks be utilised for certain voice applications; some of these include teleconferencing, telephony and voice instant messaging. VoIP provides a fantastic solution to just about all of the layers that make up an IP network; from those specialised voice applications like Skype right down to those low quality measures that are there to ensure the applications are running as they should be. VoIP is used in many different companies around the world, big or small, as well as in some households, particularly those that run businesses from home.

In many cases you may have heard people talking about a Voice over IP. If you haven't then you must have been hiding somewhere away from the rest of the world! Voice over Internet Protocol use technologies that allow certain voice communications through IP networks, like the World Wide Web. Creative entrepreneurs as well as some developers have had the chance to develop an entire business based on the VoIP technology in the many forms in which it is available, some of which include telephone services, corporate telephone systems and desktop applications; all of which are things are used in most businesses every single day.

VoIP is known to be a core technology that can work in almost any environment; right from software found on a desktop computer to Mac IP based telecommunications networks that are in very big businesses. For different people, VoIP serves different purposes and benefits them in a range of ways. For the ordinary home owner, VoIP can help them save money on their phone bill each month. VoIP is an excellent source of technology that should have been founded and used long ago, as it would have made many people's jobs a lot easier in the years before. But at least it is here now and it is undoubtedly here to stay. It certainly helps when you know what to do with it!

VoIP was not created only a year or two ago; the technology in fact goes back some time. It is said that VoIP has been talked about and was slowly introduced since the early 1990s, but it obviously took people some time to get to develop and distribute it. Of course, the creators and the first to use VoIP would have to first figure out exactly what it is and what it is about before they release it to the public and let other people become accustomed to the service. As long as there were internet connections, people were able to use VoIP and will undoubtedly continue to do so.

A few of the first enterprises to experience VoIP sometimes used to get frustrated with the programs and the bad sound quality they received. This is the reason why some of the very first VoIP products failed on the markets and had to be taken off. Since VoIP has been correctly optimised and developed with more people learning to understand it, communications have become cheaper and easier for people throughout the world.

Have Dial-Up? Get Satellite Internet!

For people that are dedicated to remaining up to date on all the latest technological advances that come out on the market, the mere mention of dial-up internet must sound like a reference to some ancient and long gone fable. Nonetheless, and to the surprise of many, there are tons of people out there in the world (and in the country!) that still are using their phone modem to surf the web...a travesty in the opinion of anybody that values efficiency and speed in their dealings! With the advent of satellite internet, there has never been a better time for the poor souls suffering with the tedium and pain of a dial-up modem to upgrade to modern connection speeds and a whole host of other benefits, which you'll only be able to access via satellite.

It is hard to imagine that any person still using a dial-up modem in today's world could possibly perform work tasks or fulfill any sort of obligation involving use of the internet. Hence the need that dial-up users have for switching to a modern alternative, and asap! The biggest difference that these people will notice when they switch to a satellite internet connection will undoubtedly be the drastically reduced waiting and download times. In fact, to be precise, the leading internet connections via satellite dish provide download speeds that are over 50 times faster than a dial-up equivalent. Can you imagine the benefits of being able to accomplish 50 times as much work in a day? Or of having 50 times as many entertainment options at your disposal? Whatever the outcome, the amount of time spent in front of the monitor tapping one's fingers on the desk and nervously biting one's nails awaiting the completion of a download will definitely be cut back to almost unnoticeable periods. Whereas with dial-up you could end up waiting for several hours just to download a file of a few hundred megabytes, with satellite internet you won't have to put up with more than just a few minutes' delay.

Amazingly, there isn't a community or individual in the country that isn't eligible for a satellite connection from one company or another. Basically, all you need in order to have a satellite internet service installed in your home is a straight and unblocked view of the southern sky, which practically any property can offer up; the only foreseeable place where this might be a problem would be in crowded cities (where there is less need for satellite connections, and if they're wanted an arrangement can always be made to use the apartment building's roof space). For the people still using dial-up, who are mostly out in far-flung communities nowhere near cities, this one requirement is not likely to pose a problem.

As the technology has become increasingly available and the amount of companies working in the field has grown, the general quality of a satellite internet connection has at this point become incredibly high and reliable-which is why nobody has an excuse to keep using dial-up from here on out!

Communicate using satellite internet

Satellite internet is a great way to stay connected. If you live outside the area serviced by other high-speed internet providers, satellite broadband might be the option for you in your home. With speeds of up to fifty times faster than dial-up -- and terrific rates for the all-important downloads you will need -- high-speed satellite internet will keep your employer happy and your position secure. You are always connected. You will no longer need to multi-task while online, as dial-up users have been known to do. I have heard the stories of people pressing "internet connect" and then going to make a cup of coffee. Next, they will type in the address for a website -- and get dressed while it loads. Finding an email with some files for a work project, they will click "download" -- and then check to see if the washer has finished its cycle. Yes, it's internet at its worst and in the past it was the only option.

Those days are over. The technology of satellite internet is not as daunting as it may seem. You will need more than a telephone and an internet installation, but not too much more. Once the satellite dish is installed by your internet provider, some minor adjustments to your network are made and you will be up and running at professional-grade speeds. You can receive and return emails at your convenience, as early or as late as you like. You can whip through the web, browsing multiple pages at once, keeping extra tabs and windows open without slowing down your system. Of course, you should keep your computer as clean as possible to run at maximum speed, something often overlooked by the computer user. Unused items languishing on your desktop can add time to the system boot on your computer, as will unused programs which clog up your storage space.

Much like satellite tv, satellite broadband has opened the door to a new sort of independence in the business world. For many of us, the daily office grind is no longer what we wish for in our lives, if it ever was. Nonetheless, if you want that professional feeling, you can still pretend like you're at the office. So get dressed and bring your coffee to your desk. When you sit down to work, you will be able to get going immediately. Just forget about the commute, even to the café: the internet (and the work) instead will come to you.

NBI in the Telecommunication Industry

Data in the telecommunications industry has now evolved into various forms, with fixed, mobile and broadband services constantly and simultaneously feeding them out to perpetually data-hungry users. To cope, operators are slowly turning to more long-term solutions like Network Business Intelligence (NBI) to deal with traffic problems that make New York City streets during rush hour look like a stroll in the park.

The telecommunications industry has never before seen an overwhelming influx of services and demand for QoS (Quality of Service) as it does today. And with the emergence of various networks such as 2G, 3G, 2.5G, and HSDPA, the rapidly increasing number of users, and the various types of data, audio, video and text, it seems that the end is nowhere in sight.

In the past, the solution to a surge in data traffic was simply to increase the bandwidth. Recently however, telecom operators have realized that doing so has slowly become nothing more than a band-aid solution. They spend a lot of money setting up the necessary infrastructure to double or triple the bandwidth, in some cases even more, only to find out that the demand easily catches up.

Let's go back to the city traffic analogy. When a city grows, so does the traffic. However, despite bumper-to-bumper conditions, city administrators don't automatically conduct road-widening operations. Knowing that such conditions don't happen round the clock nor do they happen in all streets at the same time, they implement traffic management schemes. Re-routing, one-way streets, and scheduling are some of the common strategies.

Network Business Intelligence (NBI) is similar to those traffic management schemes. Operators who implement NBI have this as one of their primary objectives: to maintain uptime in all services simultaneously. There's nothing more irritating to any customer than not being able to use a particular service. With NBI, it would be possible to reduce the bandwidth of certain services to accommodate another. Reduced speed and capacity is not as serious an issue as total unavailability.

Network Business Intelligence is not without its own complexities. New software will have to be installed and people will have to be trained. These too will have certain effects on a company's ROI. NBI is not much about generating new revenue as it is on saving on costs. But with the current economic environment, not many people will disagree that the latter would be the more prudent option.

Fiber Optics

is becoming apparent that almost everything is being replaced with fiber optics as an appropriate means of communication signal transmission. Fiber optics simply use light pulses to transmit information down lines of fiber. A transmitter, which is at one end of the system, is the place of origin for information coming onto the optical fiber lines. After the transmitter accepts coded electronic pulse information from copper wire, it translates the information into equivalently coded light pulses.

Using a lens, the light pulses are funneled into the fiber medium where they travel down the cable. On multi-mode fiber, the light is usually 850nm for shorter distances and 1,300nm for longer distances. On single-mode fiber, the light is usually 1,300nm for shorter distances and 1,500 for longer distances.

Single-mode fiber is a single stand of glass fiber, usually consisting of 2 fibers, with a diameter of 8.3 to 10 microns and has only one mode of transmission. Single-mode, having a relatively smaller diameter than multi-mode, carries higher bandwidth than multi-mode, but requires a light source with a narrow spectral width. Although single-mode fiber costs more than multi-mode, it gives you a higher transmission rate and up to 50 times more distance. The small core virtually eliminates any distortions that could result from overlapping pulses, providing the least signal interruption and the highest transmission speeds of any fiber optic type.

Multi-mode optical fiber has a slightly larger diameter, ranging from 50 to 100 microns. The most common size is of multi-mode fiber optic cable is 62.5 microns. Light waves are dispersed into multiple paths, or modes, as they travel the cables core
Unlike singlemode multi-mode can become distorted at the receiving end, resulting in an unclear and incomplete data transmission during long cable runs.
