How Did Broadband Internet Access Start
Broadband is the shortened name for broadband internet access. It allows for a high data rate connection which means downloads, sound, flash, and data transfers can be completed quickly. Almost everyone has the internet or has at least heard of it, However, most people do not know how it started or the methods used for receiving it.
In 1950's the US Military was searching for better communication network methods than they currently had available. The research led to project ARPANET in the late 1960's. The goal was to create new networking technology allowing research centers and universities to link to each other. It was available only to military, universities and research centers until the 1980's. Its use was still heavily restricted by the US Government.
Those restrictions are blamed for stalling its growth until 1991 when all restrictions regarding commercial internet use were repealed. Broadband technology was able to then move forward. Many commercial businesses began to then offer dial-up internet access on a larger scale then they had been able to previously.
At first dial-up internet access was available in the home, using telephone wires. The dial-up connection tied up the telephone line and people had to disconnect from it in order for household members to make a phone call. The only solution at the time to the interruption or busy signal was to have a separate phone line installed dedicated for internet use only.
More technological advances were quickly made and one solution to the slow dial-up was DSL, Digital Subscriber Line. It still uses ordinary telephone lines that are plugged into a modem, connected to a computer. The service is always on, the signal is always traveling to the modem even when the computer is turned off.
Satellite access is also available. It uses a satellite to send and receive information through a modem to your computer. Satellite internet is expensive and slower than DSL, but for rural communities it is the only method they currently have available for internet.
Cellular broadband uses cellular phone towers to access the internet. Due to cellular companies now using third generation networks (3G) and moving to fourth generation (4G), the signal from the towers support fast data transference. To connect the signal to a computer a USB cellular modem or router is used.
Wi-Fi is another method used for having access to the internet. No wires or connectors are required. It uses the same radio waves cell phones do. If you have the required hardware in your computer, and are in range of the radio waves, you simply connect to it. The hardware on your computer turns the information to be transferred into radio waves. The information is sent to a wireless router and decoded then forwarded through the internet. The same works in reverse when receiving information on the computer.
Broadband internet access has become less expensive due to competition. The internet has become a part of everyday life and is now available to people through their phones. Everything from doing research, shopping, watching movies, and listening to music is accomplished using the internet.
