2. Submission doc.: IEEE 802.11-15/0809r0 July 2015 Dmitry Cherniavsky, SiBEAM, Inc.Slide 2 Abstract Concurrent links double/triple the network throughput Beamforming minimizes the interference in concurrent links. This presentation proposes an extension to existing beamforming protocol for concurrent link operation for 802.11ay link.
