Fast Broadband Internet Connection
For everyone on every location the best solution
Speed = Quality
Bandwidth vs. Speed
Speed can also determine the quality of the video you are watching, or audio you are listening to. Everyone has experienced frustrating delays waiting for a movie or song to download, or watching a movie that stutters and skips on your monitor, or displays a message indicating that your connection is “buffering.” (Buffering simply means your connection cannot handle the speed at which the video is being delivered to your computer screen, and must therefore momentarily collect data to play back, just as a printer collects data you send from your computer to print.) Depending on which application you are using, the speed of your connection will often determine whether it is even possible to run the application effectively. A movie is not enjoyable to watch if it takes twice as long to watch, and stops playing every few minutes. So, how fast of a connection do you need to perform specific tasks, and run certain programs?
Bandwidth vs. Speed
There are two different factors to consider when measuring speed. Bandwidth refers to the size of the conduit in which the data is traveling within. Speed refers to the rate at which the data is traveling at. Using that definition, you can quickly see that a larger bandwidth will permit more data to travel, which will also increase the rate at which it travels. However, this does not necessarily mean that the speed of your broadband connection will be the same as your bandwidth. Bandwidth simply refers to the size of the “pipe” in which it is traveling.
For example, let's say you're transferring a file at 128kbps. If you start to transfer another file it will compete for bandwidth and slow your speed down. If you increase your bandwidth by adding another 128kpbs ISDN line, your first file will still travel at 128kpbs, but now you can transfer both files at 128kbps without sacrificing speed. An analogy would be a highway with a 65mph speed limit. Even if more lanes were added to handle more vehicles, the speed limit is still 65mph.
Units of Measurement - Megabits and megabytes
Broadband speed is measured in megabits per second, commonly stated as Mb or Mbps (i.e. 15Mb or 15 Mbps). Make sure you don't get confused between megabits and megabytes (which tends to be written as MB, or GB when referring to gigabytes). There are eight bits in a byte, so, if your download speed is 8 megabits per second (8Mb), then that's actually shifting 1 megabyte per second (1MB). It's an important distinction because the size of many files, including songs, photos, and movies, are described in megabytes, as are download allowances.
You may also see Kb and KB - kilobits and kilobytes; there are 1,024KB in a MB, and 1,024MB in a GB - the same is true for Kb/Mb/Gb.
Now that you are able to determine what speed you need to run the applications you want, which broadband technologies can you use to deliver those speeds?
By its very definition, broadband is a high speed Internet connection - which is also always on. Dial-up access, on the other hand, requires a modem to initiate a 56 Kbps connection to the Internet. The FCC raised the minimum speed of broadband to 4 Mbps downstream, and 1 Mbps upstream. This is now the new standard for a minimum broadband connection.
The FCC lays out an ambitious goal in the National Broadband Plan with regard to broadband speeds. The 100 squared initiative proposes to make 100 Mbps broadband available to 100 million people by 2020.

Broadband Providers and Advertised Speeds
Broadband providers advertise speeds in ranges for this very reason. It is difficult to estimate specifically how fast a specific connection will be. Providers know they can provide a certain amount of bandwidth to handle specific amounts of data – but they do not know precisely when this data will be traveling, or when specific demands will be placed in the network. So, instead of promising speeds that would be impossible to continuously maintain, they offer speeds which fall within certain ranges. For example, one provider offers broadband Internet packages in the following ranges for download speeds:
  • 768 kbps to 1 Mbps
  • 1.5 Mbps to 3 Mbps
  • 4 Mbps to 7 Mbps
  • 10 Mbps to 15 Mbps
Your connection speed should fall within the ranges listed for the packages offered. The bandwidth for these offerings should not be less than the maximum speed listed. For example, you cannot have speeds of more than 15 Mbps with a bandwidth of 15 Mbps. Some providers offer speeds “up to certain speed.” In these cases, the “up to” speed is the bandwidth, which means that the speed you will actually experience could be much lower.
The Difference Between Upload and Download Speed for Broad-band Bandwidth
In essence, there is no difference between uploading data and downloading data aside from the direction of the data transfer. The faster your Internet connection speed, the faster your uploading and downloading capability. Bandwidth plays an integral role in both your upload speed and your download speed. Ideally, upload and download speeds are most easily measured when they are symmetrical, which means the same speed for uploads and downloads. However, often providers only advertise the speed of the data in the fastest direction, which is usually the download speed. Download speeds are also usually much faster than upload speeds, because most Internet users retrieve data from the Internet – not transmit data and files to the Internet. If you are a user who uploads large files or other information over the Internet, you should look for faster upload speeds.
