Hi Adrian, Yes, I am assuming a simplified unicast scenario (peer to peer communication). In that case, one packet can be handled by the hardware. Upon completion of directional transmit process, the antenna is always kept at omnidirectional configuration.On the other hand, cases like broadcast/mu

.. in fact, what I'd really _really_ like is if someone would build an open source phased antenna array that's intended to be used by three-stream (ie, three transmit/receive chain) antenna devices. That way we could do both phased array station operation (when it directs its transmit power _to_ a

Hi Adrian, Thanks for the reply. I am realize there might be hardware constraint for me to use sectorised antenna. I currently have a NIC with only one antenna exposed . I have reconsidered my scenario and now I am planning to use switched beam antennas (specifically ESPAR antenna). This antenna

Hi, Yes you can do this. The trick is changing the antenna config for each frame you send out. If you do it with an rs232 port then you have to only hand the hardware one packet at a time. If you hand it multiple packets to different nodes, you won't be able to do per-destination antenna configur
