TWO DSL manufacturers – Ikanos (www.ikanos.com) and Metalink (www.metalinkbb.com) – are demoing hardware capable of speeds of up to 100 Mbps over single copper pairs (i.e. ordinary phone copper) at the Fast Net Futures (www.pulver.com/fastnet) conference in Santa Clara, CA.
Both companies have announced Japanese and Korean telcos are going to use their chip sets to deliver 100Mbps service at distances up to 300 meters. Both companies are making noises of pushing DSL single-pair copper performance to a mind-blowing 150 Mbps and to extend distances for faster speeds as well.
Alternatively, the signal processing capability can be used to extend service distances over existing copper plant, trading off lower speed for longer distance; Metalink can currently offer DSL-speed service at distances of up to 5 kilometers.
Cable companies will also layout their visions of the future at Fast Net Futures and their roadmaps to deliver service of at least 50-100 Mbps over existing cable plant within the next few years. Sigh. Guess I'm going to have to get another cable modem, but it's a small price to bear for such blinding speeds.
Contrast this with current cable modem, DSL, and wireless offerings in the States. Cox recently bumped up their speed rate from 1.5 Mbps to 3 Mbps on local cable modem service and is now offering a "Premier" package to boost speeds to a max of 4 Mbps downstream and 384Kbps upstream. Of course, they want an extra $30 for the 30% increase in performance, so it remains to be seen how it will fly. Comcast Cable's premier package is 3 Mbps as well. Both services are beating typical American home DSL price/performance over the head, since the Bells are typically offering a max of 1.5 Mbps downstream and there's a lot of wishy-washy talk in the promise depending how far your house is from the local CO (Central phone Office).
If that wasn't amusing enough, Verizon Wireless's Broadband Access service is getting a lot of fresh ink from the Establishment computer press. Originally deployed in DC and San Diego, Verizon is going to roll out the 3G EVDO wireless service to a good chunk of U.S. cities over the summer. The cell phone-based service has the potential to deliver up to 2 Mbps downstream and around 128 Kbps upstream...under ideal conditions. In reality, performance depends on how good of a cell phone signal you can get, back-end infrastructure (some cell phone POPs only have 1.5 Mbps T1s, can't fit 2 Mbps down that), and loading on the cell network. More users on the cell network, less throughput.
Despite these caveats, the service typically delivers anywhere between 300-500Kbps downstream and 40-60 Kbps. I've tested it, and having flashbacks to the days when 2400 baud modems were hot stuff, this service is practically black magic. Unfortunately (or fortunately for Verizon's DSL division), the service is only currently supported through a PC-Card modem, so unless you have a hack on your desktop, this is laptop-only. The modem costs around $150 with the rebate and the service is a flat rate $79.95/month. Should you travel outside of Broadband Access territory, the data service falls back to 1xRTT within Verizon cell land and you get kicked back to a max of 144 Kbps downstream and 40-60 Kbps upstream. Not great, but not bad, considering the alternative is Zippy, or hunting around for a hotspot.
