Abstract: A system and method is provided to establish a global positioning service with massive availability of “position-learning” radio communication nodes. Each communication node learns of its geographic coordinate in a global sense by harvesting location information from neighboring communication nodes. By conducting telemetry multiple times and implementing an error index, each communication node maintains its geographic coordinate with a precision that improves progressively over time.

Abstract: An antenna apparatus includes a parabolic dish and a receiver located at the focal point or multiple receivers nearby the focal point. In the one receiver case the receiver includes multiple receiving elements with a common adjacent angle around the axis of the parabolic dish, to create an array of antenna with different polarizations. In the multiple receiver case each receiver includes multiple receiving elements that create an array of antenna with different polarizations. The receiving elements transmit and receive non-orthogonal electromagnetic waves. The receiver(s) may include a reflector located next to the receiver which becomes an antenna resonator. The reflector enhances the transmitting gain by reflecting the electromagnetic waves. The receiving elements transmit and receive the electromagnetic waves using MIMO technology.

Abstract: Disclosed is a mutually-assisted proximity informer system and method with wireless devices, by which a message contained in a message unit is received/transmitted between a plurality of wireless devices with a relay process. An original message unit of a frame format embedded with an ID, a message/status and a relay sequence is generated and issued by one of the plurality of wireless devices and is then received and retransmitted voluntarily one by one with others of the plurality of wireless devices until a termination of the relay process of the message unit, in which the relay sequence is constantly incremented before the termination of the relay process for the delivery of the message. A simple message delivery to a longer distance far away is obtained by means of wireless devices even of a short or a limited communication range. Encryption for security and reliability and establishment of a communication tunnel are also provided by specific implantation into the message unit and operations.
