Abstract: A method of communicatively linking a plurality of electronic devices via users includes the steps of remotely linking the electronic devices in a closed communication network from a facility; verifying each user for the electronic device in an authorized manner in order to activate the electronic device by connecting a user smart phone of the user to the electronic device; restricting each user to remotely access the electronic device in limited locations within an area of the facility via a GPS unit built-in with the electronic device and within a range of the closed communication network; and connecting the electronic devices with each other through the closed networking system that allows the user to selectively communicate with each other and to selectively execute different applications preloaded in the electronic device through the closed communication network in a real time manner.
