Locating and provisioning devices in a network
First Claim
1. A method of provisioning a device, the method comprising:
- initializing a radio frequency identification (“
RFID”
) device;
reading RFID tag data from an RFID tag;
inserting the RFID tag data in an option field of a DHCPDISCOVER request; and
sending the DHCPDISCOVER request to a Dynamic Host Configuration Protocol (“
DHCP”
)server.

Abstract
Methods and devices are provided for locating, identifying and provisioning devices in a network. According to some implementations of the invention, a combination of EPC code information and existing networking standards form the basis of identifying and provisioning methods. For example, location information included in a DHCPDISCOVER request can be used to determine appropriate configurations for networked devices. In some such implementations, the location information is read from an RFID tag near the networked device and is inserted in the DHCPDISCOVER request. The location information may include any type of absolute or relative coordinate, positioning, cartographic or similar information and/or information from which such information may be derived.
