3G will work only when your sim is in the phone, while wifi can work with no sim(Nokias mainly) in wifi hotspots. |

Well... Both are completely different.. 3g is third generation mobile phone telephony. Wifi on the other hand is a technology like bluetooth which enables devices to interconnect with each other. Thats the best explanation i can think of right now!

3g is telcos stuff run on 2100Mhz. As with telco it usually available in very wide area (subject to provider/telcos BTS network). Use SIMs from telcos and have max bandwidth 384 Kbps (0.384Mbps). Future 3.5g is already available (faster to 2MBps+).
Wifi is wireless computer network stuff that intended mainly for laptop and computer and usually cover just 30-100m from the wifi hub (hence called hotspot to mark where wifi is available). The wifi hub (operated by provider/coffe shop) is usually connected to the internet using ADSL modem, Cable modem or any other means). Mainly run on 2400Mhz except (a) standard that is pretty much dead. This is what is available in coffe shops or airports and you need to configure your device to speak to each coffeshop that offer wifi hotspot. Need a wifi capable device (can be phone, laptop, PDA, etc). In theory can go up to 11Mbps (b), 54Mbps (g), and newer (n) is even faster. But you will find speed vary with distance to the base(hub). Device speed will follow the lowest speed that is used by you or the hub. Also this speed means you and hub, not necessarily you and internet (that would depend on the base hub to internet connection).
There would be a wimax soon that basically a wifi for longer range (up to KMs). Not yet common now.
Bluetooth first developed by Ericsson and mainly intended for phone and accessories. It has much lower speed compare with wifi (forget the spec). However it also use much less power making it ideal on device with batteries. Bluetooth also has limited pairs that can work together. Usually is used in computer as accessories (mouse/keyboard) and headset. Also run in 2400Mhz but can coexist with wifi.

Well not really must be a PC. If your phone has a full fledge web browser (like opera mini) and you can access FREE hotspot (like in Changi Airport Singapore) then you can browse the net for free using your mobile via wifi. Opera (full but I think mini as well) can even open a WAP page as well (and html). However wifi is power sucking so you may need extra batteries. |
