Methods and systems for determining signal strength maps for wireless access points robust to measurement counts

摘要

Examples herein include methods and systems for determining signal strength maps for wireless access points robust to measurement counts. An example method comprises receiving data related to RSSI for a wireless AP for a plurality of locations of an area, and determining an intermediary signal strength map for the wireless AP based on the received data related to the RSSI for the wireless AP. The method also includes associating the intermediary signal strength map to a regularized signal strength map for the wireless AP that is based on a diffusion mapping model of signal strength. A given partition of the regularized signal strength map is linked to one partition of the intermediary signal strength map. The method also includes providing an output signal strength map for the wireless AP including values of the regularized signal strength map modified based on values of the intermediary signal strength map.

1. A method comprising:
receiving data related to received signal strength indication (RSSI) for a wireless access point (AP) for a plurality of locations of an area; determining an intermediary signal strength map for the wireless AP based on the received data related to the RSSI for the wireless AP, wherein the intermediary signal strength map is configured to overfit the received data based on multiple RSSI measurements linked to partitions of the intermediary signal strength map; associating, by one or more processors, the intermediary signal strength map to a regularized signal strength map for the wireless AP, wherein the regularized signal strength map is based on a diffusion mapping model of signal strength for a given wireless access point and includes a plurality of partitions, wherein a given partition of the regularized signal strength map is linked to one partition of the intermediary signal strength map; and providing an output signal strength map for the wireless AP including values of the regularized signal strength map modified based on values of the intermediary signal strength map.
