3 Configuring Smartant
3.1 Overview
Smartant means smart antenna, also known as auto-sensing antenna array. It is composed of three parts: antenna array,
beam forming network, and beam forming algorithm. By adopting algorithms meeting certain criteria, Smartant adjusts the
weighted amplitude and phase of each array signal and thereby adjusts the radiation pattern of the antenna array to
enhance required signals and suppress interference signals.
Smartant can solve network interference and signal fading and increase system capacity.
Smartant is usually used in a complex environment where, for example, a lot of obstacles or certain interferences exist.

Basic Concepts
Smartant
Based on beamwidth, antennas are divided into omni-directional and directional. Omni-directional antennas usually
provide a wide horizontal coverage but a narrow distance, which is contrary to directional antennas. Smartant combines
the advantages of both omni-directional and directional antennas. It can cover 360 degree horizontal radiation with a
longer distance at each angle.
Wireless Packet Training
Smartant samples STA communication packets for training. When an STA transmits downlink traffic, Smartant changes
the direction of packet transmission by setting the transmitting antennas, extracts the rates of packet loss in different
antenna directions for evaluation, and finally computes an optimal path for antenna transmission based on the beam
forming algorithm.
Overview
Finds an optimal transmission path between the AP and STAs for the best performance.
3.3.1 Smartant Path Selection
With Smartant enabled, the AP can find an optimal transmission path for each STA.
