Replacement of mobile phones

  Universal SIM phones with Roaming in Fixed network.

Many may think it is a crazy idea, but look a little deeper. In the years to come the distinguishing factors between Wired and Wireless network will have to vanish except for the type of terminal device and the end link. 

With increase in data speed, the Wireless cell areas will become smaller and smaller in turn making the wireless portion in the whole network also smaller, ie. the end cell to device and the remaining wil be on OFC. Most part of the Wireless network will have to be on OFC back bone which is similar to the present FTH networks.  

In fact the wired network has more potential for high speed data products as much high quality, higher bandwidth could be realized. With these, there will be change in the end user terminal in fixed network also. So in due course, there will be a universal system of telephony practice where the back bone is OFC and end link is wireless, common type of connectivity with different type of user terminals which could be used as required.  

There will be no distinction between wired and wireless networks; every phone line will have roaming facility, every phone will have SIM and there will be different types of user devices which could be logged from any where to access your service, at home, in the office, in the car, in trains and may be in aero planes also. The terminal in the house can be a fully loaded system that can handle mult-Mega bit multimedia products and networked with your Home Theatre and other gadgets. The phone in the office could be a desk top one with connectivity with your personal laptop andthrough it to the office network. And then the sleek mobile one while you are moving around, for you to just login and use. In  the car with a hands free and connectable to your car TV and audio system and your personal Laptop. And then a sleek mobile while yu in the outdoor. Every device can have a SIM in it which gets activated when you switch on the device overriding the other devices. Which other method can provide number portability, better than this?Those interested may please see my posting "Roaming in Fixed Networks" in Telecom&IT community
