Broadband is a high speed connection that allows fast access to the internet and make it always connected. If we look behind, the history of mobile broadband is starting from the discovery of an optical fiber cable in 1950, whereas previously the need for data communication has not been required in high speed. Only in the 1990s came a large need for high speed data transmission. This is the beginning of the broadband era. At that time, fiber-optic cable is the only one flagship course.
Starting in 1999, the development of large capacity data transfer and high speed have been widely used, especially with the advent of cable TV services which require a cable modem. At the time, not less than 1.5 million cable TV customers more and liven up a new era of broadband. However, because fiber-optic cable is quite expensive, the development of broadband can be considered as relatively slow, and its users are limited. Lately, though cable TV has many customers, more development is triggered by the advent of technology, ADSL (asymmetric digital subscriber line). ADSL can spend millions of bits of information in seconds on the regular telephone network.
ADSL broadband works at two speeds. It can receive and also send data, so it is suitable to use for browsing and sending or receiving e-mail. Data transmission speed, slower than the receive data. ADSL standards receive data or information at a speed of 2 Mbps (35 times faster than standard modems) and send data at a speed of 256 Kbps (five times faster). However, broadband capacity is usually between 256 Kbps and 10 Mbps. Now,Mobilt bredbånd has larger capacity and speed to support more lager users.
