Broadband Satellite Internet:

What Is Satellite Internet?

High-speed Internet is increasingly becoming a must have service for today's bandwith hungry Internet users.

Satellite Internet is a high speed broadband solution for rural or remote areas where DSL or high-speed cable Internet access is not available. Broadband satellite Internet is available just about anywhere in North America with an unobstructed view of the southern sky.

If you want a high speed Internet connection, and cable or DSL are not options then broadband satellite Internet access is the best route to take.

How Does Satellite Internet Work?

A satellite dish is mounted on the exterior of your home or business.

High speed data is transferred to the ISP's Network Operations Center "NOC" through the satellite dish via a satellite modem that connects to your computer.

Internet data requests are sent up to a satellite that relays the request down to the NOC. The satellite Internet provider's NOC provides a very high-speed connection to the Internet. Your data request is processed by the NOC and then sent the up to the orbiting satellite which in turn relays the data down through your satellite dish to your satellite modem. The satellite modem then transmits the data through your computer's Network Interface Card "NIC", and your PC processes the data.

One-way or two-way Satellite service?

There are two different types of satellite service, one-way and two-way.

With one-way service the satellite can't transmit and only only receives downstream data. This configuration requires you to use a dial-up Internet connection to send internet requests or upload files. Downstream data and file downloads are then processed by your satellite modem.

With two-way service the satellite modem processes both uploads and downloads, and a dial-up connection is unnecessary.

The two-way option is definitely the way to go if your satellite Internet service provider offers it.
Why Is Satellite Internet Better Than Dial-Up?

Satellite Internet is significantly faster than traditional dial-up Internet access.

This increased speed gives you the option of sharing your broadband satellite Internet connection on multiple computers in your home or office. Even if you are only using one computer to access the Internet, downloads that took hours with dial up are now completed in minutes. No more waiting for updates or large files to download. Web pages containing graphic animation, movie clips, or streaming audio will load much faster than dial up. Downloading large files such as photos and video email attachments is much faster.

With two-way satellite Internet service you are always connected to the Internet. There is no need to dial an ISP, so you can surf the Internet without tying up your home phone line.
How Fast Is Satellite Internet?

Broadband satellite Internet service is not as fast as it's DSL or cable counterparts, however it's significantly faster than a traditional dial up Internet connection.

Satellite Internet transmission speeds will vary depending on a number of factors. Type of satellite service, provider package, weather conditions, signal losses and other factors will affect transmission speeds.

Broadband satellite Internet download speeds typically range between one hundred kilo bits per second "Kbps" and several hundred Kbps.
How much does Satellite Internet cost?

Satellite Internet access is generally more costly than DSL, cable, or dial-up and requires more equipment, namely a satellite dish mounted on the outside of your home or office.

In addition to increased service fees, you will also need to purchase a satellite dish and modem and pay to have the dish installed. If you have the skills you can opt to install the dish yourself. Most satellite providers have a self-installation kit available for a small fee.
What Equipment Do I Need?

A satellite network interface commonly called a "satellite modem" connects to a two or three foot satellite dish or base station that is installed on the outside your home or office.

Your computer's network card is then connected to satellite modem using a standard CAT5 network patch cable. Many computers come with the network card installed, otherwise they are relatively cheap and easy to install.

You can also connect your satellite modem to a router to provide broadband satellite Internet access to your entire home network.

Broadband High Speed Internet

What is Broadband?
High-speed Internet access or "broadband" allows users to access the Internet and Internet-related services at significantly higher speeds than those available through "dial-up" Internet access services. The Federal Communications Commission (FCC) generally defines broadband service as data transmission speeds exceeding 200 kilobits per second (Kbps), or 200,000 bits per second, in at least one direction: downstream (from the Internet to your computer) or upstream (from your computer to the Internet).
How does Broadband work?

Broadband allows users to access information via the Internet using one of several high-speed transmission technologies. Transmission is digital, meaning that text, images, and sound are all transmitted as "bits" of data. The transmission technologies that make broadband access possible move these bits much more quickly than traditional telephone or wireless connections, including traditional dial-up Internet access.

Once you have a broadband connection to your home or business, devices such as computers can be attached to this broadband connection by existing electrical or telephone wiring, coaxial cable, or wirelessly.

What Are The Advantages of Broadband?
Broadband allows you to take advantage of new services not available with a dial-up Internet connection. One such service is Voice over Internet Protocol (VoIP), an alternative to traditional voice telephone service that may be less costly for you depending on your calling patterns. Some VoIP services only allow you to call other people using the same service, but others allow you to call anyone who has a telephone number - including local, long distance, mobile, and international numbers.

Broadband permits new developments in telemedicine, where patients in rural areas can confer online with medical specialists in more urban areas.

Broadband helps you efficiently access and use many reference and cultural resources, such as library and museum data bases and collections. You also need broadband to best take advantage of many distance learning opportunities, like online college or university courses, and continuing or senior education programs. Broadband is an important tool for expanding educational and economic opportunities for consumers in remote locations.

In addition to these new services, broadband allows you to use existing services such as online shopping and web surfing more quickly and efficiently. Downloading and viewing videos and photos on your computer are much faster and easier. With broadband you can access the Internet by turning on your computer without needing to dial-up your Internet Service Provides (ISP) over a telephone line, which permits you to use the Internet without typing up your telephone line. As of the end of 2004, 35.3 million residential and small business subscribers had opted for broadband connections.
What Types of Broadband Are Available?

Broadband includes several high-speed transmission technologies such as:

* Digital Subscriber Line (DSL)
* Cable Modem
* Fiber
* Wireless
* Satellite
* Broadband over Powerline (BPL)

The broadband technology you choose will depend on a number of factors. These include whether you are located in an urban or rural area, how broadband Internet access is packaged with other services (like voice telephone and home entertainment) and, of course, price and availability.

Digital Subscriber Line (DSL):

DSL is a wireline transmission technology that transmits data faster over traditional copper telephone lines already installed to homes and businesses. DSL-based broadband provides transmission speeds ranging from several hundred Kbps to millions of bits per second (Mbps). The availability and speed of your DSL service may depend on the distance from your home or business to the closest telephone company facility.

The following are types of DSL transmission technologies:

* Asymmetrical Digital Subscriber Line (ADSL) - used primarily by residential customers, such as Internet surfers, who receive a lot of data but do not send much. ADSL typically provides faster speed in the downstream direction than the upstream direction. ADSL allows faster downstream data transmission over the same line used to provide voice service, without disrupting regular telephone calls on that line.
* Symmetrical Digital Subscriber Line (SDSL) - used typically by businesses for services such as video conferencing. Speed of downstream and upstream traffic is equal.

Faster forms of DSL typically available to businesses include:

* High-data-rate Digital Subscriber Line (HDSL); and
* Very High-data-rate Digital Subscriber Line (VDSL).

Cable Modem:

Cable modem service enables cable operators to provide broadband using the same coaxial cables that deliver pictures and sound to your TV set.

Most cable modems are external devices that have two connections, one to the cable wall outlet and the other to a computer. They provide transmission speeds of 1.5 Mbps or more.

Subscribers can access their cable modem service simply by turning on their computers without dialing-up an ISP. You can still watch cable TV while using it. Transmission speeds vary depending on the type of cable modem, cable network, and traffic load. Speeds are comparable to DSL.
Fiber:

Fiber, or fiber optics, is the newest technology available for providing broadband. Fiber optic technology converts electrical signals carrying data to light and sends the light through transparent glass fibers about the diameter of a human hair. Fiber transmits data at speeds far exceeding current DSL or cable modem speeds, typically by tens or even hundreds of Mbps. However, the actual speed you experience will vary depending upon a variety of factors, such as how close to your computer the service provider brings the fiber, and how the service provider configures the service, including the amount of bandwidth used. The same fiber providing your broadband can also simultaneously deliver voice (VoIP) and video services, including video-on-demand.

Telecommunications providers (mostly telephone companies) are offering fiber broadband in limited areas and have announced plans to expand their fiber networks and offer bundled voice, Internet access, and video services.

Variations of the technology run the fiber all the way to the customer's home or business, to the curb outside, or to a location somewhere between the provider's facilities and the customer.
Wireless:

Wireless broadband connects a home or business to the Internet using a radio link between the customer's location and the service provider's facility. Wireless broadband can be mobile or fixed.

Wireless technologies using longer range directional equipment provide broadband service in remote or sparsely populated areas where DSL or cable modem service would be costly to provide. Speeds are generally comparable to DSL and cable modem. An external antenna is usually required. With newer services now being deployed (WiMax), a small antenna located inside a home near a window is usually adequate and higher speeds are possible.

Fixed wireless broadband service is becoming more and more widely available at airports, city parks, bookstores, and other public locations called "hotspots". Hotspots generally use a short-range technology that provides speeds up to 54 Mbps. Wireless fidelity (Wi-Fi) technology is also often used in conjunction with DSL or cable modem service to connect devices within a home or business to the Internet via a broadband connection.

Mobile wireless broadband services (3G) are also becoming available from mobile telephone service providers and others. These services are generally appropriate for highly-mobile customers and require a special PC card with a built in antenna that plugs into a user's laptop computer. Generally, they provide lower speeds, in the range of several hundred Kbps.
Satellite:

Just as satellites orbiting the earth provide necessary links for telephone and television service, they can also provide links for broadband. Satellite broadband is another form of wireless broadband, also useful for serving remote or sparsely populated areas.

Downstream and upstream speeds for satellite broadband depend on several factors, including the provider and service package purchased, the consumer's line of sight to the orbiting satellite, and the weather. Typically a consumer can expect to receive (download) at a speed of about 500 Kbps and send (upload) at a speed of about 80 Kbps. These speeds may be slower than DSL and cable modem, but download speed is about 10 times faster than download speed with dial-up Internet access. Service can be disrupted in extreme weather conditions.

Obtaining satellite broadband can be more costly and involved than obtaining DSL or cable modem. A user must have:

* a two or three foot dish or base station - the most costly item;
* a satellite Internet modem; and
* a clear line of sight to the provider's satellite.

Broadband over Powerline (BPL):

BPL is the delivery of broadband over the existing low and medium voltage electric power distribution network. BPL speeds are comparable to DSL and cable modem speeds. BPL can be provided to homes using existing electrical connections and outlets.

BPL is an emerging technology, currently available in very limited areas. It has significant potential because power lines are installed virtually everywhere, alleviating the need to build new broadband facilities to every customer.

Getting Broadband:

Contact a provider in your area, which can be a local telephone company or other provider for DSL and fiber, a cable company for cable modem, and a wireless or satellite company for wireless broadband. There are differences among broadband services, and the equipment of one provider may not work in another area or with another provider. Check with your broadband service provider for information on compatibility. Providers sometimes offer promotions or discounts on necessary equipment.

Prior to ordering service, check with the service provider to find out the cost and transmission speeds promised. Be aware that the actual transmission speeds you experience depend on many factors, and may be less than the maximum potential speed stated by your provider. After receiving the service, contact your provider regarding any problems. Investigate obtaining service through a different provider if you are not pleased with your current service or provider.

Accelerated Dial-Up Internet

What Is Accelerated Dial Up?

Anyone who has surfed the Internet using a dial-up connection is aware of how slow web pages load. This is due to the fact that your dial-up Internet connection speed is limited by the bandwidth of phone line.

Although you can't increase the bandwidth of your dial-up Internet connection without upgrading to a high speed broadband provider, you can dramatically increase your existing browsing speed. Accelerated dial-up requires no new hardware and works with your existing phone line and modem.

How Does Accelerated Dial Up Work?

Special advanced compression and caching software is installed on your computer. There's generally a configuration menu where acceleration preferences can be set, such as image compression levels, excluded sites, etc.

You then connect to the Internet via the providers' high speed proxy server that reduces web site access time and can filter unwanted ads and other unnecessary objects. This process vastly reduces the amount of data that needs to be transmitted through the telephone line that connects your computer's modem to the Internet.

The data and image compression software will provide an immediate improvement in performance. Caching saves time by avoiding unnecessary repetitive data transmission by intelligently retaining and reusing data that had previously been downloaded to your computer .The longer you use the software the greater improvements you should notice in surfing speeds due to the effect of caching.

Because not all data can be productively compressed some web content such as encrypted data from secure web sites can not be accelerated.

What Gets Accelerated:

Each web accelerator works a little differently, but generally the following is true of most accelerators. All text including the HTML, CSS, Javascript, and other markup of the web page, email message text, and other downloaded text files are compressed on the fly. This process is similar to the familiar drive compression or zip / unzip process. The files are decompressed to their original state as they are downloaded to your computer.

Web site images such as GIF and JPG graphic files are already in a compressed state. The acceleration server will then reduce the quality of the image somewhat to create an acceptable trade-off in image quality vs speed gained through the reduction process.

What Doesn't Get Accelerated:

Other than the web images described above, most compressed files such as MP3 music files, MPEG and other video files, P2P and ZIP file downloads, and gaming and streaming video feeds will not be accelerated.

Encrypted data from secure sites https:// such as banking and secure shopping checkout pages will be sent in its' original form, and no speed increase will be realized when downloading this type of content.

How Fast Is It?

Most accelerated dial-up providers claim that web pages load an average of 3 to 5 times faster. Naturally, the specific speed increase you will receive is determined by many factors including the types and frequency of web sites that you visit. Some users have reported up to 20 times speed increases for specific web pages.

The longer you use the software and more regularly you visit specific web sites, the greater the performance boost you will notice.

Is Accelerated Dial Up For Me?

Only you can answer this question, since everyone has different needs and expectations. Web acceleration software is available as a subscription service, but many Internet providers include accelerated dial up with their service package.

You will find many introductory special deals as you compare your accelerated Internet options using our low cost dial up provider comparison chart.

Internet providers to combat child porn

New York (AP) - Five leading online service providers will jointly build a database of child-pornography images and develop other tools to help network operators and law enforcement better prevent distribution of the images.

The companies pledged $ 1 million among them recently to set up a technology coalition as part of the National Center for Missing and Exploited Children. They aim to create the database by year's end, though many details remain unsettled.

The participating companies are Time Warner Inc.'s AOL, Yahoo Inc., Microsoft Corp., EarthLink Inc. and United Online Inc., the company behind NetZero and Juno.

Ernie Allen, the chief executive of the missing children's center, noted that the Internet companies already possess many technologies to help protect users from threats such as viruses and e-mail "phishing" scams. "There's nothing more insidious and inappropriate" than child pornography, he said.

The announcement comes as the U.S. government is pressuring service providers to do more to help combat child pornography. Top law enforcement officials have told Internet companies they must retain customer records longer to help in such cases and have suggested seeking legislation to require it.

AOL chief counsel John Ryan said the coalition was partly a response to Attorney General Alberto R. Gonzales' April speech identifying increases in child-porn cases and chiding the Internet industry for not doing more about them.

The creation of the technology coalition does not directly address the preservation of records but could demonstrate the industry's willingness to cooperate.

Plans call for the missing children's center to collect known child-porn images and create a unique mathematical signature for each one based on a common formula. Each participating company would scan its users' images for matches.

AOL, for instance, plans to check e-mail attachments that are already being scanned for viruses. If child porn is detected, AOL would refer the case to the missing-children's center for further investigation, as service providers are required to do under federal law.

Each company will set its own procedures on how it uses the database, but executives say the partnership will let companies exchange their best ideas - ultimately developing tools for preventing child-porn distribution instead of simply catching violations.

"When we pool together all our collective know-how and technical tools, we hope to come up with something more comprehensive along the lines of preventative" measures, said Tim Cranton, Microsoft's director of Internet safety enforcement programs.

Ryan said that although AOL will initially focus on scanning e-mail attachments, the goal is to ultimately develop techniques for checking other distribution techniques as well, such as instant messaging or Web uploads.

Representatives will begin meeting next month to evaluate their technologies, determining, for instance, whether cropping an image would change its signature and hinder comparisons. Also to be discussed are ways to ensure that customers' privacy is protected. Authorities still would need subpoenas to get identifying information on violators.

The companies involved said they are talking with other service providers about joining. But companies that do not participate still are required by law to report any suspected child-porn images, and many already have their own techniques for monitoring and identifying them.
