Betting a Broader View on Broadbands

The mere mention of broadband comes to mind high speed access and telecommunication. But things are not as simple as that. The term broadband applies to many technologies. Broadband access for instance is a tool that delivers media services and communications-oriented applications. The media services and applications that broadband usually offers are entirely new. This distinguishes it from dial-up Internet access. It is not surprising that broadband is fast becoming the mainstream in the industry and is quite popular with consumers. Broadband improves access to audio and video and the fact that it offers always-on access connections make it even more appealing to subscribers.There are two ways for consumers to get broadband access. The first is through DSL or Digital Subscriber Lines. DSL is another technology used for high-speed and high-bandwidth. The high-speed and high-bandwidth are directly related to the amount of data transmitted or received per unit time. There are six different times of DSL and they are as follows: Asymmetric Digital Subscriber Line (ADSL), Symmetric Digital Subscriber Line (SDSL), ISDN Digital Subscriber Line (IDSL), High-bit-rate Digital Subscriber Line (HDSL), Very high-bit-rate Digital Subscriber Line (VDSL), and Rate-Adaptive Digital Subscriber Line (RADSL). Each of the six types has various limitations, capabilities, and ranges. Another way for consumers to acquire broadband access is through cable modem. Cable modems function over cable TV lines. They offer high-speed access to the Web or corporate Intranets. Cable modems usually require a power splitter and a new cable. The splitter is used to divide the signal of the "old" installations and the new segment that connects the modem. The three types of cable modems are the external modem, internal modem, and interactive set-top cable box. A disadvantage of cable modem is that the service it offers is shared bandwidth. The rate of connection will depend on how many people are using the cable modem and how many are on the network. This is one advantage that DSL has over cable modems.

Let us further compare the two services. When it comes to popularity, both services are quite popular in the United States; although cable modem's popularity is a little higher than DSL's. Cable modem is faster than DSL Internet, but not always. Several technical and business reasons reduce or eliminate this advantage over DSL. Theoretically, cable indeed runs faster than DSL. Cable technology supports about 30 Mbps of bandwidth, whereas DSL cannot even reach 10 Mbps. When it comes to customer satisfaction, DSL tops cable modem. On security issues, both have an advantage. Both cable and DSL implement various network security models. Historically speaking, cable had more issues raised, but its providers have taken steps to improve security over the past few years.

In data transmission, broadband means something else entirely. Basically, it refers to data transmission involving multiple pieces of data. The data are sent simultaneously to increase the rate of transmission. On the other hand, in network engineering, the term broadband is applied to methods where two or more signals share a medium. This definition is clearly different from what has been identified with broadband access.
