Smart antenna system for reading data tags
A method and apparatus can provide system ( 20 ) for reading radio frequency identification tags ( 22 ). The system includes one or more individual readers ( 24 ), and each individual reader has an operative power supply ( 26 ), antenna ( 28 ), and communication system ( 30 ) for relaying data from the individual reader to an electronic data collection and management system ( 32 ). A computerized electronic processor ( 34 ) is separately and remotely located from the readers, and implements a programming of protocols for each antenna and reader. In a particular aspect, the electronic processor can provide digital signal processor logic and protocol code to each reader.
1 . A system for reading radio frequency identification tags, the system comprising:
at least one individual reader, the individual reader having an operative power supply, antenna, and communication system for relaying data from the individual reader to an electronic data collection and management system;
a computerized electronic processor which is separate and remotely located from the readers, and implements a programming of protocols for each antenna and reader;
wherein
the electronic processor provides a significant portion of the digital signal processor logic and protocol code needed by each reader;
2 . A system as recited in claim 1 , wherein the electronic processor provides at least about 50% of the digital signal processor logic and protocol code needed by the reader.
3 . A system as recited in claim 2 , wherein the electronic processor provides up to about 100% of the digital signal processor logic and protocol code needed by the reader.
4 . A system as recited in claim 2 , wherein the protocol code includes at least the code for Transmission Control Protocol, and the code for Internet Protocol.
5 . A system as recited in claim 1 , wherein the reader has a plurality of individual antennas configured to interrogate and receive data from tags, and the tags have been configured to operate in different, widely-spaced frequencies or frequency bands.
6 . A system as recited in claim 5 , wherein one or more individual antennas have been programmed with one or more electronic product code protocols.
7 . A system as recited in claim 1 , wherein
the system includes a plurality of individual readers; and
each individual reader has an operative power supply, antenna, and communication system for relaying data from the individual reader to the electronic data collection and management system.
8 . A system as recited in claim 7 , wherein the electronic processor provides at least about 50% of the digital signal processor logic and protocol code needed by the readers.
9 . A system as recited in claim 8 , wherein the electronic processor provides up to about 100% of the digital signal processor logic and protocol code needed by the reader.
10 . A system as recited in claim 9 , wherein the protocol code includes at least code for the Transmission Control Protocol and Internet Protocol.
11 . A system as recited in claim 10 , wherein the individual reader has a plurality of individual antennas configured to interrogate and receive data from tags, and the tags have been configured to operate in different, widely-spaced frequencies or frequency bands.
12 . A system as recited in claim 11 , wherein one or more individual antenna have been programmed with one or more electronic product code protocols.
