Mobile Terminology - need help?

Hi,





am thinking of buying a new mobile and have come across terms which i may understand in a generic sense but have not been able to gauge their use vis-a-vis mobile phone. To be more clear , what can a user do with mobile phone having the following features:





WIFI


WLAN


UMTS


EDGE


GPRS


HSDPA


A2DP





tried googling them; explanations seem to be more technical in nature (need some one to plain speak.)





Appreciate any assistance provided.

wifi is a high speed wireless internet connection. if a phone has wifi, you can connect to a wifi network (unless at no charge) and go online to internet at very fast speeds (like cable internet). usually you dont have to pay extra for that. (at least on my blackberry i dont).


WLAN. wireless local area network. i dont see how this relates to phones unless u buying an internet card for your laptop. but its pretty much like wifi network but "local".


UMTS.EDGE.GPRS are all types of internet connections UMTS being the fastest and GPRS being the slowest . GPRS can only handle "basic" text-only websites where UMTS can handle streaming video etc. A2DP is for stereo bluetooth where you can listen to music on your bluetooth headset. you will need a bluetooth headset thats "A2DP compatabile" . hope this helps
Reply:WIFI allows you to connect wirelessly to an internet connection i.e. your wireless router. Think WLAN is same, not sure. UMTS is 3G for video calling and faster data transfers (good for downloading MP3 and video files). EDGE is faster than GPRS but slower than UMTS. HSDPA is faster than UMTS (I think) and A2DP is used in Bluetooth which allows for stereo music playback on stereo Bluetooth headsets (the older Bluetooth chips only support mono sound).
