# Vertically oriented beams using antenna arrays

Referring to the above picture, can an antenna array mounted on Node A direct beams towards Node B and Node E, without the need for an antenna rotator (or manually orienting the antenna array towards the respective nodes)? In other words, can the antenna array orient its beam along the vertical direction (along the line joining Node B and Node E)?

The motive for this question is related to the upcoming IEEE 802.11ad standard. By operating at 60 GHz, users communicate with one another through directional beams pointing at each other. Without the use of mechanical rotators for the antennas, how could these users possibly orient their beams in a changing/moving environment?
