There has been a tremendous evolution in the space of broadband technologies. This started with Narroband (telephone line - dial up) which used to provide speeds upto 56 KBPS which I still feel was good speed for normal internet browsing. This was then evolved into DSL technology (Always-ON) broadband - xDSL (ADSL, VDSL, RADSL etc.) The latest trend in DSL is ADSL2+ which can provide upto 40M speeds. However, DSL always had distance limitations associated with it. There have been other broadband technologies - Cable (DOCSIS 3.0 provides upto 50 Mbps speeds), wireless broadband. But the "need for speed" has always been increasing. The latest trend is Fiber to the Premises or curb or cabinet with Fiber as a access mechanism. The current GPON tech. for fiber now supports upto 2.4 GBPS (if 32 way splitter is used - this mean each individual user can get upto 70 to 100 Mbps.). I am still concerned, do we have such a high bandwidth-hungry applications which need such high speeds. Typical gaming applications need 4 Mbps, HDTV require 19MBps, SDTV require approx. 4MBps.
Going by this speed, what's the next? Are we talking about Broadband speeds of GBs? The day will soon come where our PC speed will be slow than what Broadband can offer.
While 56K felt "sufficient" back then, it was higher bandwidth that improved the nature of web contents. Back then, it was only HTML data (text) with broadband, multimedia is common place.
ReplyDeleteMost of the cloud computing is made possible due to availability of high speed and stable internet connectivity.
Talking about broadband in India, while things are better comaprde to few years ago, we are no where near mbps speeds for all.
I do agree...PC will stop to exist..there wil be other from of personalisation experience...straight out of a SCI FI movie...
ReplyDeletePpl talking to their fridge, TV, washing machine and even your home telling you it is time for a white wash.....
Next GEN BB is on the way...Fibre...wireless and on power line...it is just coming towards you at a high speed...
