The article writer is a douche by: Anonymous on 7/28/2009
3g/4g is NOT GSM only you moron, it stands for 4th Generation. Those can either be CDMA or GSM. Wifi and Wimax are Simplified terms for the 802.x Standard. Consider WiMax better Wifi, it makes sense.

The terms "fixed WiMAX", "mobile WiMAX", "802.16d" and "802.16e" are frequently used incorrectly.[14] Correct definitions are the following:

802.16-2004 is often called 802.16d, since that was the working party that developed the standard. It is also frequently referred to as "fixed WiMAX" since it has no support for mobility.
802.16e-2005 is an amendment to 802.16-2004 and is often referred to in shortened foricm as 802.16e. It introduced support for mobility, amongst other things and is therefore also known as "mobile WiMAX".

Do your homework next time, and don't try and be pessimistic about technology, something you dont know. Try knitting.

Just one question then... Wi-Fi can be considered as 3G or 3.5G then?
I can has fact checking plz? by: General Lee D. Mented on 3/27/2009
Ugh, where to start.... first of all I'll assume the comments keeping whitespace issue is unfixed so I apologize for the ensuing mess. I'm not sure if it supports HTML spacing (br tags etc) and there's no PREVIEW button (cmon guys get this site's shit together already) so I won't test it. In fact I'll email you a dupe of this comment in case you want to fix the formatting.

Anyway as for real comment. 4G is technically "beyond 3G", so many call WiMax "4G" or a "4G technology", which lumps in 802.16e, 802.20, LTE Advanced, etc.

Sprint DOES have a 4G network, and has for a while now, it was called XOHM and launched in Baltimore in late Sept/early Oct 2008: http://www.wi-fiplanet.com/news/article.php/3775921 with hardware made by Zyxel that you could actually buy: http://74.125.93.104/search?q=cache:6ndjbQEBaFIJ:www.newegg.com/Product/Product.aspx%3FItem%3DN82E16825184001+zyxel+xohm+newegg&cd=1&hl=en&ct=clnk&gl=us Hell Acer even shipped a version of the Aspire 6930G with Xohm support built in: http://www.acer.us/acer/productv.do;jsessionid=F78D2C3D034239C4A71868D568490AA0.public_a_14c?link=oln7e.redirect&changedAlts=&kcond22e.c2att101=39857&rcond80e.c2att92=447&CRC=1703255737

So, Sprint has had "4G" for a while. In May, they bought up/merged with Clearwire, which was doing a similar thing down in Texas: http://www.betanews.com/article/SprintClearwire-WiMAX-launches-with-35-billion-in-funding/1210181201 but that took a while to get FCC approval, and so didn't get finalized until about December, when it got renamed "Clear": http://www.wi-fiplanet.com/news/article.php/3789776

So, Sprint's 4G WiMax network is called Clear. It's operating in several cities with test areas popping up all over.

Oh and what 14.4Mbps HSDPA 3.5G devices have you seen? Most of the new ones are only getting to 7.2M now, and the older ones supported 3.6 or 1.8. My Samsung SGH-U800 for example, used to manage about 2.3Mbps real world on Vodacom's network in South Africa (Which incidentally charges less for prepaid bandwidth than any US carrier does for contract). You can see a Xohm based Aspire pulling > 4mbps down and 1.5 up while in a moving vehicle here: http://twitpic.com/f4uq so, REALISTICALLY, and by that I mean NOT ON SPEC SHEETS, are you getting 3.5G speeds while driving that top that? WiMax supposedly tops out at what, 35Mbps? 70? I forget what the current generation goes to.
