Alcatel-Lucent 100Mbps technology on copper lines
- bradleyland 15y agoThe problem with virtually all technologies that utilize existing copper infrastructure that was built to deliver analog phone service is that it degrades severely over distance and is heavily dependent on the quality of the cabling. Analog voice quality degrades linearly. It doesn't suffer significantly from splicing, repairs, or bridge taps. For data services delivered over these lines, these factors can be catastrophic.
- kalleboo 15y agoI'm tired of these theoretical bandwidth numbers getting further and further away from the real-world bandwidth numbers. On the original UMTS 3G labeled "384 kbit" we got 300 kbit, it was alright. With 7.2 Mbit HSDPA we get something closer to 2-3 Mbit. The same thing with WiFi - I've never ever seen anything anywhere close to the 300 Mbps theoretical rate of 802.11n WiFi. Cable numbers are diverging in a similar manner, and the DSL numbers currently quoted are only possible to achieve when you're 100 meters away from the DSLAM...
