Tag location,client location, and coverage hole location in a wireless network
First Claim
1. A method of determining location of a radio tag or client station of a wireless network, the method comprising:
- receiving from a plurality of wireless stations of the wireless network path loss information of the path loss of one or more location frames received at the respective wireless stations, the location frames transmitted by the radio tag or client station and having a pre-defined frame structure; and
determining the location of the wireless station or radio tag from the path loss information, wherein the radio tag or client station uses for transmitting a location frame, a common infrastructure configured for radiolocation by path loss measurement, the common infrastructure including a pre-defined protocol common for both radio tags and client stations for transmitting information for reception by the plurality of stations of the wireless network for radiolocation, the pre-defined protocol including using the location frame having the pre-defined frame structure.

Abstract
Determining the location of a radio tag or client station of a wireless network, and the location of coverage holes by receiving from a plurality of wireless stations of the wireless network path loss information of the path loss of one or more location frames received at the respective wireless stations. The location frames transmitted by the radio tag or client station having a pre-defined frame structure. The radio tags and client stations use a common infrastructure for transmitting a location frame configured for radiolocation by path loss measurement. The common infrastructure includes a pre-defined protocol common for both radio tags and client stations for transmitting information for reception by the plurality of stations of the wireless network for radiolocation. The pre-defined protocol includes using the location frame having the pre-defined frame structure.
