Wired Broadband Solutions Available Today

DSL technology - DSL technology uses the existing copper telephone infrastructure to facilitate high speed data connections.DSL equipment achieves this by dividing the voice and data signals on the telephone line. There a number of different DSL technologies, the key ones are ADSL, RADSL, HDSL, SDSL, and VDSL. The advantage of this technology is we can go for higher capacities with low implementation cost. And some types of DSL technologies give capacity according to requirement. The main advantage is the capacity will goes down when we increase the length of the line from the DSLAM to customer.

Hybrid Fiber Coax (HFC); Cable TV - Digital cable TV networks are able to offer bi-directional data transfer bandwidth in addition to voice and digital TV services. The advantage of this technology is that where the coaxial cable is in good condition and RF amplifiers exist (or can be installed) to extend the network reach, relatively high bandwidths can be provided to the end user without distance limitations. The disadvantage is this network is shared network. If the customers increase the bandwidth will be shared.

Broadband Power line (BPL) - Broadband Power line systems allow for high speed data transmission over existing power lines. BPL system, the data is transmitted over the existing power line as a low voltage, high frequency signal which is coupled to the high voltage low frequency power signal. The advantage of this solution is a cost-effective way to service a large number of subscribers with broadband. The disadvantage BPL is, it requires a high investment cost, to upgrade the power transmission network and bypass transformers, to support high speed and reliable broadband services.

And also we can’t use it with power transformers.

FTTx - FTTx is a generic term for those technologies which bring fiber, a step closer to the subscriber. It has many technologies related to ‘x’. They are FTTN - Fiber-to-the-node, FTTC - Fiber-to-the-cabinet, FTTB - Fiber-to-the-building, FTTH - Fiber-to-the-home ect. Using FTTx we can get fast Internet access with simultaneous delivery of high definition IPTV and voice over IP. But the disadvantage is high implementation cost of fiber.
