第5章 結論

This report researches advanced technologies and markets for wireless and wired communications systems that are supported by MIMO - Multiple Input/Multiple Output structures - to enhance their performance. It revises and updates earlier issues of the report as well as adds the analysis of latest technologies.

Users' demand for more efficient networking brought to life many technological innovations. One of them is MIMO, which became very popular in wireless systems - almost all recent and future 3GPP standards use (or will be using) variations of such a technique. MIMO is also used in wireline systems.

This report is based on the Practel analysis of MIMO-based communications systems, their technologies and markets specifics. Particular, the following industry standards that utilize MIMO have been considered:

• 3GPP LTE
• IEEE802.11ax
• IEEE802.11ay
• IEEE 802.11ac
• HomePlug AV2
• ITU G.hn.

The goal of this report is to characterize MIMO advantages and specifics for each standard. It also addresses market characteristics of discussed technologies. Report concentrates on profiling the industry players and their products.

MIMO characteristics, structures and types are also addressed and compared. The report also surveys patents related to the discussed subjects.

The report is written for a wide audience of managers and technical staff that involved in the design and implementation of advanced communications systems.
