1. A method for determining locations in a predefined area for placing a Radio Frequency Identification (RFID) reader in order to obtain a full coverage of the predefined area, comprising:
- arranging a plurality of hexagonal areas together to form a combined area until the total area of the combined area is at least equal to the predefined area, wherein each hexagonal area represents an area of coverage of the RFID reader;
aligning the predefined area within the combined area; and
determining the hexagonal areas which are at least partially covered by the predefined area,wherein the center of the hexagonal area which is determined to be at least partially covered by the predefined area corresponds to one of the locations for placing the RFID reader.

Abstract
A method for determining locations in a predefined area for placing a Radio Frequency Identification (RFID) reader in order to obtain a full coverage of the predefined area is provided. The method includes arranging a plurality of hexagonal area to form a combined area until the total area of the combined area is equal or larger than the predefined area, aligning the predefined area within the combined area, and determining the hexagonal area which is fully or partially covered by the predefined area. Each hexagonal area represents an area of coverage of the RFID reader, and the center of the hexagonal area which is determined to be fully or partially covered by the predefined area corresponds to one of the locations for placing the RFID reader.

13. A location optimizing unit for determining locations in a predefined area for placing a Radio Frequency Identification (RFID) reader in order to obtain a full coverage of the predefined area, comprising:
-
a hexagon field generator for receiving a reading range of the RFID reader and generating a combined area comprised of a plurality of hexagonal areas, wherein the length of each edge of the hexagonal area represents the reading range of the RFID reader; a rectangular area generator for receiving dimensions of the predefined area and generating a rectangular area representing the predefined area; an alignment optimizer for receiving the combined area and the rectangular area, and aligning the rectangular area with the combined area and determining the hexagonal areas which are at least partially covered by the rectangular area; and a hexagon center locator for determining the centre of the hexagonal areas which fully are at least partially covered by the rectangular area, wherein the determined center of the hexagonal areas corresponds to the locations for placing the RFID reader. - View Dependent Claims (14, 15, 16, 17, 18)
