Various Broadband Connection

Broadband, also known as broadband internet access, is a high data-transmission rate Internet connection that make use of two of the most popular consumer broadband technologies – cable modem and DSL. With any of these technologies, your Internet connection could easily transmit data faster than 56 kilobits per second (the highest speed of a traditional dial-up modem).

The popularity of broadband internet access radically increased in many countries starting 2000. These kinds of Internet access can surf hundred times faster than conventional dial-up modems, thus the name “high-speed Internet”.

Commercial broadband Internet commonly has 256 kilobit per second, which is about the slowest broadband speed for connections advertised worldwide. However, since there is no standard bitrate defined by the industry, the term “broadband” could imply also low-bitrate transmissions or others call “narrowband”. Consequently, some consumers turn out to be disappointed about the promised Internet speed of their connections.

The Technology Behind Broadband Internet Access

The most important assessment you have to make is the kind of broadband internet you want. There are various technologies behind broadband access and you should understand these technologies to fully appreciate this service. Things you have to think about include cost, speed requirements and your location, whether home or office. Since there are many choices for high-speed connections, you should be able to know how each one works and find out which service can benefit your work or lifestyle the most.

Some Internet service providers use multi-linking technologies that achieve a faster surfing speed by doubling the speed of dial-up modems. However, if you wish to subscribe to this feature, you should have two dial-up accounts, two telephone lines, two modems and the ISP provider for multilinking. This is the oldest kind of technology and was used way before DSL, cable broadband and other higher-speed connections were available.

The most common technologies for broadband in many countries are DSL and cable modems.

The most common broadband internet is Digital Subscriber Line (DSL). This technology works by using your phone lines to transmit digital signals directly, without having to convert to analog signals. DSL offer higher data rates and allows you to connect anytime without using your phone line, making it available for incoming calls. There are many kinds of DSL, but asymmetric digital subscriber line (ADSL) is probably the most popular for subscribers.

Cable is another type of broadband internet, which uses the fiber networks to give your cable television at home and use them for internet access. Meaning, you get to divide a given amount of bandwidth for a neighborhood. The limitation of cable internet is that some condominiums and buildings do not have cable installed. When this is the case, it could take time to install your internet subscription because building codes and other legal issues should first be done.

Satellite is the kind of broadband internet that is frequently recommended as an alternative for DSL. However, satellite internet is more expensive because you will need an antenna or a dish to receive data signals from the provider’s satellite.

Other new technologies, such as optical fiber and VDSL are now adding to consumer’s choice for higher-speed Internet connections. Although fiber-optic internet services are used lately, the technology had played a vital role in allowing consumers to connect to broadband Internet using a more cost-effective solution even over larger coverage.

The biggest challenge in broadband is to offer the service to customers in any area, even with low-population densities. Since setting up the broadband Internet access in a particular area could cause many thousands of dollars for equipment alone, many service providers do not have the network in some rural areas for fear that they will not recover the costs.

Although some local Internet providers provide these solutions, many have limitations and drawbacks. The most common problem for rural Internet providers is that these companies usually depend on the quality of local telephone companies.

In some locations that have no DSL or cable Internet, Wi-Fi networks serve their Internet needs. In other countries, high-speed mobile Internet access, such as HSDPA, EV-DO and stationary-broadband WiMax are used.

With today’s modern world where businesses and even home-based employees rely on the Internet for everyday communications and worldwide access, broadband and other high-speed technologies present consumers and businesses a expedient way to hook up to the net.

Regardless of what you choose, you can really see the difference of dial-up from broadband internet in terms of speed, reliability and performance once you plugged your computer on.

Development of the Mobile Internet

According to many sources, one of the greatest factors to inhibit the use of mobile internet is the speeds that are available. When a person has a benchmark against which to measure a service then the newer service needs to provide better results or additional features that make it more attractive. In the case of the mobile internet many people already have a faster connection from their home of office computer.

This leaves the mobile internet to provide services that will attract new users, but there is only so much of a gap in speed that the features such as mobility can cover. Unfortunately at the moment the gap is too great for most people, particularly for those people who use GPRS services. The introduction of 3G cards was trumpeted as the arrival of competitively high speeds, but for many this turned out to be untrue. One of the greatest factors working for the benefit of mobile internet is that new products and technologies are constantly being produced.

All service providers are currently trying to increase the speed of their bandwidth to attract additional customers. One of the problems is mobile internet will constantly be compared to standard broadband speeds and be found wanting. The rates that are charged by the service providers, such as T-mobile or Orange, are also higher for comparative speeds than fixed line broadband providers are. Since different service providers offer different packages people do have a choice, but often it is viewed as a choice of the lesser of two evils.

The number of mobile phones that are capable of surfing the net is increasing very quickly as it quickly becomes an expected feature on new mobile phones being released. The majority of service providers still focus on providing data cards for laptops though. This is attributed to the inability of many phones to browse the internet at a sufficiently fast rate for users. One of the greatest problems when browsing the internet on a mobile phone is the tiny size of the screen.

This has lead to an increasing number of people who are now designing their web sites so that it is possible to get a vaguely decent browsing experience. This entails coding the site so that it will be easier to view than standard sites on a mobile phone screen. Until such time as all sites are set up in this way the speed of the mobile internet will be less important. Who cares if a page can load quickly if you can’t see it properly when it has loaded?

Mobile Internet Satellite Broadband – chapter 1

Being on the road has its advantages; the freedom is the biggest one. One draw back was the Internet Service, but having done much study on the mobile Internet Satellite Systems and future technologies; I was able to become a beta tester of the MotoSat system in 1999. I have used the system ever sense.

My company, the Car Wash Guys had joined forces with a Strategic Alliance of GM Hughes Satellite Division to beta test the First Fully Self contained, fully Networked Mobile Corporate Office, taking advantage of the newest in WiFi technology. We were the first in the world to have this powerful capabilities which at the time nearly blew away the Pentagon’s Performance with their 77 million dollar investment and Iridium Bailout.

Mobile Corporate Offices are the Wave of the future, where Network Centric Warfare (Net-Centric) in the marketplace combined with strategic mobile command centers used to create a network of networks, which will eventually dominate all of their market sectors. Corporate Giants are slowly learning the game is changing. And we are the ones teaching them. We are the leaders in technology and they will have to learn the hard way. Car Wash Guys are leading everyone’s industry this time. As far as the car wash industry is concerned we left them in the dust a decade ago. Today we use 20 times less water, a third of the labor and spend less than a tenth of the capital to do it. We now have much bigger fish to fry as we go for the gold. To work with this technology you must move your business at the speed of thought.

We at our Bravo research team of WashGuys, had been studying the newest in satellite technologies. Most of our recent studies have been on satellite data transmissions and as many of you know we have become very knowledgeable over the years with satellite communications, I happened to live next door in Malibu from a physicist who worked at the Rockwell Research Center in Thousand Oaks CA. First we would like to talk about actually data transmission speeds and problems associated with relays and problems of security of data when data jumps from satellite to satellite or from satellite to ground. Also with the problems of relay where any and all data can be recorded. As everyone knows the Pentagon bailed out the Iridium project, which is good since we have learned so much from this. The 75 million dollar contract helped pay the bills of 7 million a month including the 40 million per year to Boeing who flies the satellites. Iridium was nice in that it covered the whole Earth, all oceans and remote areas, with spare satellites ready just in case. Iridium had 66 satellites in orbit in use at about 485,000 up. Very close and helps with data lag associated with satellites which is normally a half second or more. The data can be transmitted at 1Mbs, which is slow considering the Wash Guys data transmission capabilities of 10-12.265 Mps up load and the 1Mbs download, faster than that of the US Department of Defense. The other problem we see with their system is the relay in Tempe, AZ home of Motorola, which is unsafe due to the newest wave of possible terrorist devices such as the brief case electronic impulse devises which work from building tops and could easily destroy its relay station. This is why other systems, which are not voice systems and generally web based and data use satellites are much better such as the Globalstar System.

With Globalstar, which is in debt and filed bankruptcy, due to small amount of debt to Qualcomm who is also in trouble and Loral, it may cease to exist. EuroCom has a neat system, which is used in the shipping industry and there is an interesting article in Professional Mariner this month about them and a few others. It is similar to Imersat and supports PBX and PABX systems on ships. Of course the bent pipe approach by GlobalStar is worth considering its 48 operational satellites and the four spares. Only real problem is the range of 70 degrees north to 60 degrees south. And also the gaps if you let’s say in the middle of the ocean at sea level in the South Atlantic and or middle of the Pacific. Several satellites can transmit the coded signal but unlike the Iridium system the Satellites do not talk to themselves. But all in all Global Star data transmissions are still about 9.6 KBPS and actually slightly less than the Iridium system, which does not have the lapse in service.

The Iridium of course is the Arthur C. Clark theory in practice and is worthy of note; the big problem right now with data transmission is the problems with direct sight to satellite, which we have encountered. Hard for submarines, and below decks on vessels or in buildings. Good for catching bad guys who have to go out in the open to use the phone, they do not work in caves either. Iridium like all of Microsoft software has triple redundancy, and uses CDMA technologies to gateway the data from transmission point into the terrestrial system. Inmarsat Systems include the I-4 system, which can transmit data at 432 MBPS turns out to be excellent for things like video conferencing. The newest satellites by Inmarsat are said to be able to 10 times more communications than the current ones. Since the Inmarsat satellites are at 22,300 miles up three satellites cover the Earth with 3 back-ups. But remember with that altitude there is a time delay. You will notice this when you see video feed from the Middle East Wars on live broadcasts on TV, CNN.
