Fanny, your thoughts: In a mobile device, the fact that the orientation of the device is unknown, could even be an argument FOR using beamforming. The pattern of the antenna could be varied according to position (assuming we can move the beam to any point in 3 dimensions).
Horn antenas are broadband and directional. they are good for test chamber applications because of their wide bandwidth and strong field in the direction of the DUT. Vivaldi cross polarized antennas are another good alternative.
on a mobile device you may not have enough transmitters to do beamforming but the mobile device can respond to the base station with channel sounding results and the base station would then know how to beamform to that mobile device.
This field is very new to me but my experience with MEMS microphone arrays helps me understand antenna directionality. My experience in aircraft flutter testing helps me understand multi-path and mathematical transforms.
Hi all -Audio is live! If you don't see the audio bar at the top of the screen, please refresh your browser. It may take a couple tries. When you see the audio bar, hit the play button. If you experience audio interruptions and are using IE, try using FF or Chrome as your browser. Many people experience issues with IE. Also, make sure your flash player is updated with the current version. Some companies block live audio streams, so if that is the case for your company, the class will be archived on this page immediately following the class and you can listen then. People don't experience any issues with the audio for the archived version.
-The streaming audio player will appear on this web page when the show starts at 2 PM Eastern time today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser. If that doesn't work, try using Firefox or Google Chrome as your browser.

-You are eligible to earn IEEE Professional Development Hours by attending these courses and participating in the chat function. Additionally, we are no longer using the points system, offering "graduation", or giving grades. The IEEE hours are taking the place of that. There are some important things for you to know about earning the hours. The most important ones are that you need to attend these courses live, you need to attend a minimum of two of them per semester, you need to fill out a course evaluation form within 2 weeks of the end of the class, you need to attend 4 out of the 5 classes per course, and you need to participate in the chat function every day you attend. Please click on the link at the top of this page that says "How do I earn IEEE professional development hours" to read all of these important details and more.
