what is the devolpments in ADSL? HSPA+ and LTE are starting to hit huge download speeds but is ADSL keeping up?
VDSL2 deteriorates quickly from a theoretical maximum of 250 Mbit/s at source to 100 Mbit/s at 0.5 km (1,600 ft) and 50 Mbit/s at 1 km (3,300 ft), but degrades at a much slower rate from there, and still outperforms VDSL. Starting from 1.6 km (1 mi) its performance is equal to ADSL2+.
ADSL-like long reach performance is one of the key advantages of VDSL2. LR-VDSL2 enabled systems are capable of supporting speeds of around 1–4 Mbit/s (downstream) over distances of 4–5 km (2.5–3 miles), gradually increasing the bit rate up to symmetric 100 Mbit/s as loop-length shortens. This means that VDSL2-based systems, unlike VDSL1 systems, are not limited to short local loops or MTU/MDUs only, but can also be used for medium range applications.
The Koreans might soon be enjoying 600Mbps - http://bit.ly/g7eijL
- That's six times what you can ever hope to expect from LTE
- 40 times faster than 3G
- download a 700MB file in 9.3 seconds
- stream 3D HD footage on the go
and Telkom calls 384Kbps FAST INTERNET
But LTE can give 1 gigabit per second if you are stationary. That is the theorectical speed...so I am guessing 600Mbps should be achievable with LTE.
Thats even better, i'll get a fixed antenna. But when are we going to enjoy such speeds as well? And my biggest gripe is Telkom setting billboards advertising 384Kbps as FAST INTERNET.
8.4Mbps, 84Mbps or 84Gbps - it really does not matter, as long as its uncapped.
Someone should sponsor a live TV event, where they order the Lost DVD box set on amazon, and then whip open a laptop to download everything from netflix using one of these bad boys. they should attach a massive LED price board above showing how much its costing. Then, at the end of the show, explain to people that besides the countless factories and suppliers involved in making the box set, it was also put on an airplane, flown here, and delivered with a small truck to your door. It apparently costs more money and less carbon to beam a few electrons from the other side of the planet to your laptop, but more carbon and less money, to do it the traditional way. It does not take a fool to see that this is not sustainable.
