簡介

MIMO (multiple-input/multiple-output) 天線設備,是多年來佔行動通訊技術一角的存在,不過,由於幾個規定條件的關係,持續普及範圍受限的情形。可是,隨著LTE的普及和技術性演進,天線的改良、普及等,也有MIMO應該作為通訊規格之一更廣泛使用的意見擴大。

本報告提供LTE環境下的MIMO技術的有效利用的可能性相關分析,技術概要和分類,週邊設備的活用狀況和改良預測,各種通訊技術、系統的改善/經費削減的動向,產業方面、行政方面的對策,各國的LTE/5G的普及預測等調查。

MIMO (Multiple-Input Multiple Output) antenna systems have been a part of mobile technology standards for many years but have not been deployed to any great extent so far, thanks to the combination of several limiting factors. These factors include space constraints, particularly for sub 1 GHz frequencies, at the base station and in the user equipment (UE) or handset and the computational overhead required for frequency division duplex (FDD) systems - the most prolific LTE access technology. These and other challenges including fronthaul capacity, cost and power have helped limit MIMO for the most part to simple 2x2 MIMO deployments.

However, as LTE continues to evolve to more advanced versions such as LTE-Advanced, LTE-Advanced Pro and Gigabit LTE encapsulated in the 3GPP Standards, we expect that MIMO will become an increasingly important part of the mobile network operators' (MNOs) options in the evolution to 5G. Under continuous pressure to boost data throughput MNOs will first upgrade to 256 QAM and/or refarm spectrum. MIMO will be next since adding antennas is a less costly way to densify the network than building a new cell site and erecting a tower.

While MIMO has not delivered on its promises so far, we are left in no doubt that the technology will become a foundational building block for mobile networks in the evolution to 4G/5G and advanced antenna systems will receive increasing attention and R&D by both vendors and MNOs. Advanced antenna systems including complex passive antennas and large scale active antennas will become part of the roadmap to advanced LTE and 5G.
