A simple Maths.A 256kbps airtel broadband connection has 256kbps upload & 256kbps download.ie, 256/8 = 32KB for 1 second.1min= 32KB*60 = 1920KB.1hour = 1920KB*60 = 115200KB = 115MB.1 day = 115MB*24 = 2760MB = 2.76GB.30 days = 2.76GB*30 = 82.8GB.so a user can download 82.8GB in a 256kbps connection/month.also he can upload 82.8GB/month.So totaly a user data transfer/month is 82.8+82.8 = 165.6GBNow airtel gives 10% of the data transfer 15GB to its users.In 384kbps connections, its 248.8GB/month.Aitrel gives 10% ie 25GB/month.512kbps connection, its 331.77GB/monthAirtel gives 40GB/month.1mbps connection it is 663.5GB/monthAirtel gives 150GB/monthAirtel says its a govt policy.Its not govt policy.Its politicians policy.Untill Mr.dayanithi maran was telecom minister, every 3-4 months, for every major festivals, he announced some rate cut or some surprises to telecom users. After Mr.Raja became minister, their is no surprises.
