Abstract:
1. A method for optimizing configurations of a set of radio frequency identification readers under control of a host server, the method comprising: assigning, by the host server, a multicast address to each reader in the set; sending, by the host server, a multicast message to each reader assigned to the multicast address or to each reader within a given address range, wherein information in the multicast message is used for configuring or managing interrogation operations of each reader assigned to the multicast address or each reader within a given address range to begin or end interrogation operations within a reader coverage area, wherein the multicast message includes commands for interrogation configuring settings used by each reader assigned to the multicast address or each reader within the given address range, and wherein the multicast message includes commands for directing each reader assigned to the multicast address or each reader within the given address range to locate a specific radio frequency identification tag that identifies information about the type of item to which the specific radio frequency identification tag is attached or affixed; and transmitting to the host server, by a reader receiving response signal from the specific radio frequency identification tag in response to the multicast message sent by the host server, data obtained from the specific radio frequency identification tag that includes information about the type of item to which the specific radio frequency identification tag is attached or affixed.
