Modems

Modem Standards

Modem standards are defined by the ITU. Standards are always important in any field, but especially so in computer-computer communications. After all, how can you communicatiate if you haven't got a common language to speak?

Over time, these standards have become more and more sophisticated, culminating in the V.91 standard that is still undergoing ratification by the ITU. If you want more details on some of the more common modem standards then click here.

Where next?

Modem technology has been pushed pretty much as far as it can go. The current generation of 56K modems use every last trick in the book to get the speeds that they do and without changing the equipment at the exchange, this cannot be pushed further, so it seems that the modem has come to the end of its useful life.
Although modems will continue to be used for a long time to come, newer technologies are quickly making them technologically obsolete. Of these new technologies, the ones most likely to become common fastest are DSL and cable modems. High speed DSL and cable connections are already being introduced and should become common and cheaply available within the next couple of years. However, before I go on to talk about those, I will cover ISDN first.
