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.

Mobile Internet Satellite Broadband – chapter 2

We were the first beta testers of a Mobile Command Center with full Internet Access in 1999. Our mobile command center was also the first unit with WiFi and Internet Mobile Access.

The next generation of this system of Broadband Satellites was introduced in 2004. And the next wave of technology almost exists for the 10 times that speed. Looks like Moore’s Law may just apply to Satellites, however with the former practice tries by Motorola and the incompetence with the FCC we saw previously we may find that there are significant obstacle to over come still.

The biggest gripe back then was the Iridium pricing of $134.50 per month and the ridiculous cost of $1.34 per minute. Of course GlobalStar proves that they are worse at 150 per month and 1.39 per minute and International calls at $1.79. The cool thing about Inmarsat is that it is 20 years old and still has the 9.6 kbps data speed and sometimes you can get the 64 kbps. Inmarsat A is ancient and 18,000 ships have the maritime Global distress system aboard. GMDSS. If you look at most all commercial ships you will see the antennas on top that can run fax machines, Telephones and various data interfaces. Previously they ran below deck Telex systems. This system as you would guess is purely analog which has much advantages in weather conditions at sea. Inmarsat B is a whole different story with it’s digital technology, you can definitely get 64 KBPS all day long for broadcasting audio streams, video (a little jumpy), and voice and fax transmissions.

The pricing of data transmission due to speeds can save users up to 40% simply because it takes less time per minute to down and upload data. Of course the hardware runs about $ 10K, but for what it is that is not bad considering the original costs of data transmissions. Now here is the new deal Inmarsat C, two way data communications, terminals are portable and small, brief case style. Costs for terminals are only $4K approx. and everyone in the TV business has one or more. Inmarsat also has a system for voice, which needs only a little antenna of 9.3 or more inches and comes in a small dome. These were recently featured in Popular Mechanics in Nov 01. Trac Phone antennas for boats, RVs etc are expensive at $6,500 but work well. This is also known as the SatCom system mobile. It is a briefcase laptop system and is only 5 lbs. Costs only $3,000. People call it their brief case phone. It uses a SIM card for multiple users a system if you will remember never took off in the US like the smart card phones in Europe. Remember the PCS Phones had that little slide in cards, but they were too expensive for mass production in cellular technology. Inmarsat F77 is another innovation of 2001. ISDN and mobile packet data service capabilities. Delivering Fax, phone, voice and data. 64kbs, Absolutely and without a problem. Almost trouble free, this is nearly fully operational. We are almost there. This technology takes advantage of the B-GAN services that will be provided by the Inmarsat 4 being launched in 2004.

This will be cool. US Based ComSat Mobile, a division of Lockheed Martin Global Telecommunications has announced it’s cooperation with Fleet F77 in the first half of 2002. Ah ha, now we are getting somewhere ? Says the people at Stratos, who are arrogant Canadians. Why is this so cool? It means that users can send and receive data but only be charged for the data sent and received. Serf the web in broadband from anywhere or even a remote log cabin on vacation, emails and web browsing for about $89.95 per month all in real time with about 2-3 second delays for distance or in another system the one we have now it will be a half second delay with even higher speeds (I will talk further about this in a minute). Internet based systems like this means we can track every ship, truck, terrorist school bus in the country real time, just like they now track all the aircraft as we saw on TV during the 9-11 act. We watched charts of the US with every single aircraft flying.

Imagine the system capabilities for efficiency, safety, storm and weather watching, and safety of our people. I am really liking this a lot and everyone in America will be safe and the President can have his missile defense program because we will be able to track everything that moves which is not cloaked and right now that is everything that we know about. We can even track stealth bombers by frequency disruption patterns from cell phones. We win. Guess what these systems have a built in safety switch so important transmissions get there first for instance a ship in high seas in trouble, DEA transmitting while profiling a smuggler, or mayday distress calls. So if you are surfing or on line sending emails it will be delayed until the safety priorities are taken care of and at those speeds and numbers of users and the forthcoming Craig McCaw’s Law I predict to replace Moore’s Law for satellites that will not be more than a nano second by 2005. In other words you will assume a solar flare or even a thunder cloud.

Orbicomm is another data source with no voice capacity and handles two-pager and alphanumeric operations using a small network of LEO Satellites. Another web site we found of interest to you if you are using any of these technologies.
