Satellite Internet Exchange

A study conducted by ?The Economist? magazine, showed a strong correlation between the price of a ?Big Mac? in a country and it?s cost of living. The cost of living?rent, consumer goods, food, entertainment (www.ticketnest.com) is usually significantly higher in the US than in the developing world(and so is the price of a ?Big Mac?). However, ?Big Mac? index notwithstanding, the price of internet bandwidth in the third world is off the charts. As a point of comparison, a 1 Mbit/sec ADSL costs about 20 dollar for a home user in the US, and about 800 dollars in Pakistan. Needless to say, there is a strong need for a reduction in cost and improvement of quality of service.

The issue with the developing countries is the lack of infrastructure. Our case study of Pakistan showed that all of Pakistan has only one backbone fiber line, resulting in bottlenecks. The lack of redundancy has its costs?in July 2005 the fiber wire got severed resulting in massive outages. The back up satellite connection was hardly a solace to the burgeoning IT industry of Pakistan.

A significant percentage of traffic in Pakistan is domestic, but it?s routed through servers in the US and Europe. A trace route from one Pakistan ISP to another yields a shocking pattern?packets traveling from Pakistan to UK, US, Singapore and back to Pakistan. The situation is exacerbated in the case of fiber failures, when the traffic gets routed over multiple satellite hops. The latency is about 700 milliseconds/hop (or about 1.5 seconds for every transaction). This not only adds latency, needlessly raising costs but chokes the connection slowing down genuine Pakistan to international traffic.

Internet Exchange Point is a facility to allow the exchange of traffic between multiple ISP?s. In general the ISP?s have to pay to the tier-1 providers or the governing body(say Pakistan Telecom Authority) for the carriage of traffic. Even if the traffic is local, without the Exchange Point, the traffic is routed over the international internet.

The peering arrangement allows local ISPs to exchange traffic on a barter basis, rather than on a cash basis?net neutrality being the key. Such arrangements bypass ITU protocol, regarding revenue sharing and allow net lower cost to all the ISP participants. The exchange point essentially allows the ISP?s to segment the traffic, according to the destination and by pass the tier-1 providers. Results are dramatically lower cost and lower latency.

The entrenched incumbents in developing countries(such as Pakistan) have the most to lose from domestic exchange of traffic and are the biggest impediments to the adoption. The governments of such countries also have a vested interest in supporting the monopoly of Telecom companies, given the revenues and taxes received. The larger ISP?s also have a vested interest in using high cost of connectivity to hasten the exit of smaller or less capitalized players through attrition.

In conclusion, to reap advantage of internet exchange points, the telecom companies have to overcome their monopolistic ways and there has to be an effort to make a neutral body responsible for the traffic sharing facilities. The lower cost of internet will actually foster overall growth in overall traffic, which will compensate the monopolies? initial loss of international traffic.

The Difference Between Satellite Internet And DSL

What is Satellite Internet? Getting high speed internet through satellite is called as satellite internet. Satellite internet is much faster than DSL or cable internet. Satellite internet can be accessed even in remote corners of the country. They are easy to install and operate. The internet speed is higher than DSL or cable internet. Satellite internet is also called as lightning fast internet connection. You can download heavy files in quick time and even listen to online radio uninterrupted. The internet speed is constant and does not fluctuate.

What is DSL? The full form of DSL is Digital Subscriber Line. DSL internet is faster than cable internet. It is a broadband internet connection and files can be uploaded and downloaded quickly. The most important point is you need not require any new cabling to be connected to DSL internet. You can simultaneously connect through the phone lines for accessing internet and receive and make calls too. DSL internet is much more faster than dialup internet. While you opt for a DSL internet connection, you get a DSL modem for connecting to the internet.

The differences between Satellite Internet and DSL:

? You can stay connected to the internet always with the help of satellite internet. The satellite internet service provides two way internet access, which provides internet speed without fluctuations in bandwidth. While in DSL internet, the internet speed is not constant.

? Satellite internet does not require huge cabling or telephone connection to access the internet. The speed of the internet is also constant as satellite internet uses two way high speed internet. In DSL internet the internet speed depends on the telephone wires and in case there is some cabling fault then your DSL internet would come to a stand still. The better the quality of your telephone cable the better your internet speed.

? Satellite internet service is accessable anywhere at any time. You can use satellite internet even in remote places. DSL internet can be accessed where there are telephone lines.

? The downloading speeds of audio and video files are smooth while in DSL internet the files take a lot of time to download.

? If you stay in a city or a rural area the speed of the satellite internet would be the same while with DSL internet the speed would be high if you are near the main office of the DSL service provider. The farther you are located from the main office of the DSL service provider the lower the internet speed.

The best Internet solution: With technology improving day by day, the demand for internet with faster bandwidth and downloading speeds has increased and this in turn has led to satellite internet. Satellite internet can be accessed anywhere which is the most important part of this technology. No cable and no hassles for internet connection and installation. Satellite internet connection is more reliable than a DSL or dial up internet connection. If you feel that there is a need for changing your internet connection opting for a satellite internet connection would be the ideal solution.

Motorhome Satellite Internet

The Internet has moved from novelty to virtual necessity for many people in recent years. motorhome satellite internet technology brings this necessity to your motorhome.

For many people, the internet has become a way of life. It is used to keep in touch with family and friends. It is used to pay bills and handle banking transactions. It is used to retrieve information of all types quickly. All of these functions are as important on your motorhome vacation as when you are sitting at home. motorhome satellite internet semotorhomeices have made it possible to perform all of them when on the road.

The motorhome satellite internet semotorhomeices generally operate with dish type antennas. These antennas use GPS (Global Positioning Satellite) technology to locate and lock on to a satellite which provides the internet connection. The two basic types of antennas are called automatic and tripod. The automatic antennas are permanent mounted to the motorhome. They have a “stow” position that protects them from wind when the vehicle is in motion. Most of them will automatically go into stow mode when the GPS senses the vehicle is in motion, although there is a stow button on the controller.

The tripod antennas must be manually set up and connected. They are much less expensive than the automatic antennas, but the time required to set them up and take them down makes them less practical for quick internet connection during rest breaks. They are designed to be used when the motorhome has moved to a permanent camp site. People who wish to have quick access to the internet even during short stops usually opt for the automatic antennas.

The systems are not perfect. An unobstructed view of the southern sky is needed and trees or buildings can block the reception. Cloud cover and weather conditions can have some effect on reception, but usually only in the most extreme storm conditions. For the most part, access is fairly easy to achieve. Most of the satellite internet provider semotorhomeices offer broadband semotorhomeices with extremely fast download times. It is possible to combine your internet reception with satellite TV on the same system.

The initial cost of the system is a bit high, especially when you go with an automatic antenna. Once you have your system installed, the monthly costs for semotorhomeice are in line with normal internet semotorhomeice. The advantages of having immediate internet semotorhomeice in your motorhome are many. For years, motorhomeers have been carrying laptops and connecting to the internet in a variety of difficult and time consuming methods. The motorhome satellite internet system has made the internet as much a part of the motorhome experience as the stove and sink.
