Machine to Machine communication has amazing potential of connecting the world and enabling strong decision making with the help of collected data , imagine if my fridge can collect all the data as what all items are currently stored inside and what has been missing from regular schedule , how useful this data can be.
It may transfer this data to nearest super market who can then analyse requirement for entire area and organise the inventoy accordingly , subsequently the data will be availble to actual supplier.
In case TV can communicate with the bluetooth enabled fridge then whenever you are watching tv and there is an advertisement of a super market , a pop can appear on the side reminding you that there are certain items for which you may like to place order. If you are an airtel user , TV can remind you for recharge when you are watching air tel add , taking it one step further if same data collected across regions and sent to Airtel , then they would know what percentage of TV audience are already thier customer and what are not.
Similarly the Possibilities with healthcare and patient monitoring are unlimited and very execiting where gadgets attached to patients can communicate with central monitoring systems of health care centers and allow a proactive response.
In last decade this might not be so realistic but in current and coming decade with bluetooth enabled deviced and sophisticated but standard operaing systems , this and much more M2M can be realised in coming future
