Abstract :
The worldwide availability of the unlicensed 2.4-GHz industrial, scientific and medical (ISM) band has propelled the IEEE to issue the 802.11 standard for wireless LAN II. On the other hand, smart antenna technology is a valuable add-in feature to wireless LAN systems. However, the problem of near-field distortion that upsurges from the indoor channel characteristics at the mentioned band has been overlooked. In this paper we evaluate the performance of the proposed near field distortion-compensated smart antenna for indoor wireless systems under the IEEE 802.11 standard´s specifications for the 2.4-GHz band
