Abstract
A wireless network device including a signal-to-noise ratio (SNR) module, an error rate module, and an antenna selection module. The signal-to-noise ratio measures i) a first average SNR while utilizing a first antenna, and ii) a second average sNR while utilizing a second antenna. The error rate module measures i) a first error rate while utilizing the first antenna, and ii) a second error rate while utilizing the second antenna. The antenna selection module selects the first antenna or the second antenna based on i) a first comparison of the first average signal-to-noise ratio to the second average signal-to-noise ratio, and ii) a second comparison of the first error rate to the second error rate. The second comparison is selectively performed depending on the first comparison.
