The Reverse Path of existing cable networks is fairly noisy and be a source of major concern if a large number of cable modems are to be installed on a network. However the strong customer pull for Internet delivery to cable networks has led to the networks exploring alternates. One such alternate currently being explored and infact successfully deployed at Bandra, Bombay is a fairly mature computer technology that promises most of the benefits of a cable modem, without its cost penalty and probably without the problems of noise, if the network size is small. However, this technology is unrelated to cable TV and cannot be integrated on an existing cable network. It requires the installation of a complete, separate and independent coaxial cable line for each customer.
Lets take a closer look.
LANs are commonly deployed in most offices that use multiple computers. The LAN enables all computers to access common files and transfer files between computers without the need to copy them on a floppy or other removable media. A LAN typically requires each computer to have an Ethernet card. These cards are available as 10 base T or 100 base T cards. The 100 base T card provides a 10 times faster data exchange rate.
