Abstract

A method includes identifying multiple statistics associated with each of multiple wireless connections. The multiple wireless connections form a single communication path between two wireless nodes in a wireless network. The method also includes identifying an overall quality associated with the communication path using the statistics. The method can also include assigning a quality value to each statistic for each wireless connection, where the overall quality is based on at least one of the quality values assigned to the statistics (such as a lowest of the quality values). The statistics could include a Received Signal Quality Indicator (RSQI), a Received Signal Strength Indication (RSSI), and a transmit success/fail ratio. The quality value assigned to each statistic could include a “good” quality, a “fair” quality, or a “poor” quality.
