Abstract

A method and system for data communication between a base station and at least one transponder via a high-frequency electromagnetic carrier signal onto which information packets are modulated. Each information packet has a header section, a middle section, and a trailer section. The header section can be provided in a forward link of a data communication between the base station and the transponders for controlling data communication. The header section is used in a return link of a data communication in order to transmit information from the transponder to the base station.

Claims

1. A method comprising, by one or more computer systems, transmitting data between a base station and one or more transponders.
