| Summary |
IEEE 802.11ac, which is the latest standard of IEEE 802.11, supports forward-link (downlink) MU (Multi-User)-MIMO (Multiple-Input Multiple-Output), and it can improve the transmission efficiency. IEEE 802.11ax,
which is under standardization, is considered to apply reverse-link (uplink) MU-MIMO, and a further improvement
of the efficiency is expected. In this paper, we propose to introduce reverse-link MU-MIMO in addition to
forward-link MU-MIMO for wireless mesh networks, and evaluate the performance in terms of area transmission
efficiency, which indicates a number of packets in a unit area. Then, we clarify that the proposed system achieves
the higher area transmission efficiency than forward-link MU-MIMO. |
