NOKIA 3G mobile capabilities [not for expert minds] by telecominfo.in

here is the comparison between them to clear ur confusion
2G: the second generation of mobile telecommunications still is the most widespread technology in the world; you’ve basically all heard of the GSM norm (GSM stands for Groupe Spécial Mobile in French, renamed in Global System for Mobility). The GSM operates in the 850Mhz. and 1900Mhz. bands in the US, & 900Mhz. and 1.8Mhz. bands in the rest of the world (eg did you know Bluetooth stands in the 2.4Ghz. area, just like your…microwave!? But that’s another story, not related to this article) and delivers data at the slow rate of 9.6 Kbytes/sec.

2.75G: EDGE (I just called it 2.75G, 2.5′s not the official or unofficial number at all), which is a pretty recent standard, allows for downloading faster. Since mobile devices have become both a TV and a ‘walkman’ or music player, people needed to be able to watch streaming video and download mp3 files faster – that’s precisely what EDGE allows for and that’s for the good news. The bad news is that if EDGE rocks at downloading, it’s protocol is asymmetrical hence making EDGE suck at uploading ie broadcasting videos of yours for instance. Still an interesting achievement thanks to which data packets can effectively reach 180kbytes/sec. EDGE is now widely being used.

3G: also called UMTS (Universal Mobile Telecommunications Standard). Aimed at enabling long expected videoconferencing, although nobody seems to actually use it (do you know any?). Its other name is 3GSM, which says literally that UMTS is 3 times better than GSM. One issue though: depending on the deployment level of the area you are in and your device, your phone will (have to be) handle(d) from the GSM network to the UMTS network, and conversely – making billing more complex to understand for the consumers. One of the major positive points of UMTS is its global roaming capabilities (roaming is the process that allows you, at a cost, to borrow bandwidth from a telco provider that’s not yours; you usually use roaming when calling from abroad).

3.5G:HSDPA is theoretically 6 times faster than UMTS (up to 21 Mbytes/sec)! Practically speaking, this would mean downloading an mp3 file would take about 30 secs instead of something like 2 minutes.

4G:still a research lab standard, at least to my knowledge, that should combine the best of cellphone network technologies with WiMax, wireless Internet, voice over IP and IPv6. Data rates are expected to reach 100 Mbytes/sec.

IN SHORT,
3G also known as WCDMA SPEED UPTO 384kbps

3.5 also known as HSDPA/HSPA SPEED UPTO 21 mbps
