We have been given the impression this is a simple upgrade from 3 and 4G. It is a weapons system. Dr Barrie Trower & Mark Steele have also discussed this.

If you want to hear the truth about this system you will never hear it from the mouths of those pushing it in spite of all protests from the public. EWR
