ABSTRACT

Cable modems are devices that allow high-speed access to information at a distant server may it be Internet server or video on demand server, via a cable television network. While similar to the traditional (analog) dialup modems, a cable modem is significantly more powerful, capable of delivering data approximately 500 times faster. During the early to mid - 1990s, the two-way interactive communication capability of the existing cable network infrastructure was realized which would imply a much greater bandwidth for accessing the Internet. This realization resulted in several field trials being conducted in various areas of United States and western European countries. As a result of these field trials, several types of cable modems were developed. For millions of people, television brings news, entertainment and educational programs into their homes. Many people get their TV signal from cable television, because cable TV provides a clearer picture and more channels. Many people who have cable TV can now get a high-speed connection to the Internet from their cable provider. Cable modems compete with technologies like Asymmetric Digital Subscriber Lines (ADSL).Through the use of a cable modem you can have a broadband Internet connection that is designed to operate over cable TV lines. The coaxial cable used by cable TV provides much greater bandwidth than telephone lines, a cable modem can be used to achieve extremely fast access to the Web. This, combined with the fact that millions of homes are already wired for cable TV, has made cable Internet service something cable TV companies have really jumped onboard with. Traditional dial-up modems provide online access through the public telephone network. A cable modem, on the other hand, gives users high-speed Internet access through a cable TV network. Let us take a close look on

    The next evolution was Asymmetrical Digital Subscriber Line (ADSL). ADSL also utilizes the traditional POTS system, but utilizes frequencies that are not used for telephone voice. Creating an advantage over the 56k modem as the telephone can be used at the same time. Similar to its predecessor using the POTS system, but ADSL uses different modulation schemes i.e. PSK and PQSK. Most of the bandwidth is used upstream to the provider which allows the user the ability to watch low quality videos allowing the user more bandwidth faster downloads, although slower upload speeds. The disadvantages of ADSL are expenses, and ADSL was not available to everyone. The external modem and twisted pair cables were not common during ADSL’s timeframe. Providers also needed repeaters to reach homes making the product…

    The Cable modem architecture is very similar to DSL with one very important difference. DSL is a point-to-point technology whereas cable modems use shared multipoint circuits. With cable modems, each user must compete with other users for the available capacity. Furthermore, because the cable circuit is a multipoint circuit, all messages on the circuit…

    By about 2000, cable TV companies were in a technical position to offer triple play over one physical medium to a large number of their customers, as their networks already have sufficient bandwidth to carry hundreds of video channels. Cable's main competition for television in North America came from satellites, which cannot compete for voice and interactive broadband due to the latency imposed by physical laws on a geosynchronous satellite—sometimes up to one full second of delay between speaking and being heard. Cable's main competition for voice and Internet access came from Telco’s, which were not yet able to compete for television in most markets because DSL over most local loops could not provide enough bandwidth.…

    Fixed networks can come in many shapes, sizes, costs and speeds. Prices range widely, and differ depending upon the provider, but the equipment used is usually very similar. You’ve got dial-up, which uses existing phone lines to provide a very low speed, unreliable connection. There is also DSL, which uses those same telephone lines, but only works a certain distance away from your telephone company’s central office. Then you’ve got services like AT&T’s U-Verse, which also uses telephone lines in a similar manner as DSL, but has the capacity to produce much higher speeds and provide video services as well.…

    DSL is a form of point to point technology that provides high speed data transmission over traditional telephone lines. It is attractive to many because it does not require a customer to rewire the local loop to change from traditional telephone service, but merely change the telephone equipment. Operating from the local loop along with DSL makes relatively higher data transmission rates possible. DSL places equipment on the customer premises(home or office) called Customer Premises Equipment as well as using the local loop. There are different ways it can be installed, but one example of DSL installation is using a line splitter to separate the traditional voice telephone transmission from the regular data transmissions. The directing of the signal keeps voice communication safe in case of DSL equipment fail. DSL is not available everywhere, but mainly in regions such as Australia, Asia, the U.S., Canada and Europe. The most common types of DSL are Asymmetric DSL (ADSL) and Very High Data Rate Digital Subscriber…

    In the early nineties, Bangladesh had access to email via dialup to Bulletin Board Systems (BBS) of a few local providers. The combined Internet users of all the email-only service providers were not more than 500. Users were charged by the kilobyte, and mail was transferred from the BBS service providers to the rest of the world by International dialup using UUCP. In June 1996, the Government allowed VSAT's to be operated in the Private Sector, allbeit to be provided solely by the Government owned Telephone Operator, BTTB. Only a handful of ISPs were connected within the first year. However, more liberal Government policies followed in the subsequent years which led to a rapid expansion of this industry, eventually resulting in over 180 registered ISP's by 2005. ISPs are currently regulated by the Bangladesh Telecommunication Regulatory Commission through the Bangladesh Telecommunications Act.…
