That's what my analysis indicates, may be wrong since they have a large 2G subscriber base but then again you have to consider that it will need dedicated spectrum for 2G to keep running and will reduce the spectrum available for 4G and also with the zero iuc regime they will have to pay for the termination of incoming calls on 2G network from their pockets since the calling party will no longer pay for it and they can't charge incoming charges to the 2G subscribers. With 4G they can offer unlimited incoming since there is no cost involved with the pure ip framework unlike the 2G mechanism. With circles where they have non liberalised spectrum they might as well continue with 2G since that spectrum isn't usable for any other purpose and they wouldn't pay for getting it liberalised for just 5 yrs.
hey will have to pay for the termination of incoming calls on 2G network ?????? where is payment going... its just account adjustment toward asset utilization, asset include spectrum and depreciation on machineries, which VIL installed decade ago.
and in todays world tower compnies are sepeate and even there are relaxed norm for acive/passive tower sharing, so in all if 2G BTs running,how much is addional cost than pure 4G BTS on that tower.
Secondly delhi, where lot of user still having feature phone, some having dual sim smartphone,where second sim only works on 2g, and thre are many POS terminal on 2G. so i dont find near possibility of 2G shutdown.
Thes sms are onl effort to reduce loads on 2g network, so that 2G tower/BTS count can be minimized and then block of 8/6.2/4.4Mhz can be recuded to bare minimum in all possible site.
Esmail bhai, BTW I have que for you,
4G deployment works on block sixe of 5Mhz, anything below goes to narrow band like 1.4Mhz, So my que is in delhi VIL having 10.6 liberalise spectrum, after allocating 10mhz in band 3, what VIL will do with rest of 2.6
Possibility 1) deploy additional 1.4Mhz, bcause 3mhz not possible, and 1.2Mhz waste?
2) share additional with other telco like airtel to deploy 5Mhz on 4g?
3) Use 2.6Mhz for running 2g,
subsciber accodoation is 2.6mhz will be definately just 25% comapred to 8Mhz running, now till oct2021. Till that time Enjoy 2g or force upgrade to 4g is waht VIL trying to say with sms.
