Yes this is the difference in India that it will be all and all wireless tech. They will place an antenna on ur baloney or so. As far as speeds are concerned, as I have said already that till date in trial run, they are claiming to have got speed up to 50 whereas tech is capable to giving up to 100 (on paper). So now as with our experience, we get around 1/4 what they say, so in any case we are going to get at lest more than 10-12 mps speed (where it is available in full glory).
Most important point in this thing is that they have included live TV including HD feeds, so they have to make sure of a minimum speed. So all in all, either it will work this way only or it will not work at all and that is why a long testing is going on with this.
Plus being wireless, it has potential to get client in big way at least in 4 major cities.
As far as signal problem is concerned, it will be same as in case of DTH during rain...
It will be a bundled service but not just via cable, it will be through small dish and wire only they will not get good signal. In starting some problem may come but soon things will get improved...just wait for a few months guys....till then enjoy excellent pic of HBO hits and defined...
Now where there is no spectrum suitable for such high speed, even there they will be making it compatible working with 3G sets also, so more speed on 3G sets than now....
Plus in future, more players will come into it.
