Latest State-of-the Art Wireless Antenna Technology To achieve long range, wireless antennas MUST be directional. That requires careful aiming of the antenna at distant user. All distant users must be in the same direction. New phased array antenna: Aiming is done automatically and electrically. No actual physical aiming of the antenna. Covers a full sector all at once. Longer range than ANY other antenna.
