サマリー

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.

MIMO is the Next Hero Technology for 4G Cellular Networks

Multiple-Input Multiple-Output (MIMO) antenna systems now just starting to realize their full potential in LTE networks

 

Oyster Bay, New York - 17 Oct 2017

As LTE progresses to more advanced versions such as 3GPP standard LTE-Advanced, LTE-Advanced Pro, and the recently marketed Gigabit LTE, ABI Research, a leader in emerging technology intelligence, expects that MIMO will become an increasingly important part of mobile network operators’ options in their evolution to 5G. Massive MIMO will be a key feature of 5G and deploying advanced MIMO for 4G is a long-term investment which will prepare the ground for the deployment of the next generation of networks.

“While MIMO has not delivered on its promises so far, we are left with no doubt that the technology will become a foundational building block for mobile networks in the evolution of 4G and 5G and advanced antenna systems will receive increasing attention and R&D by both vendors and MNOs,” says Nick Marshall, Research Director at ABI Research. “We expect increasing acquisition activities in the antenna market, particularly involving MIMO technology.”

Overall the installed base of MIMO-enabled LTE antennas will grow by more than double worldwide from 2017 to 2021 to reach almost 9 million, with the Asia Pacific region outpacing this with a growth rate of three times. The Asia Pacific region will grow to represent most of the market by 2021. Although the MIMO-enabled LTE platform retains the largest installed base through 2021, growing by a factor of almost two times, it is the MIMO-Enabled LTE-Advanced platform growing at a faster rate and MIMO-enabled LTE-Advanced Pro at almost six times which rise rapidly to match the scale of the earlier MIMO-enabled LTE platform. The cellular antenna market forms a very dynamic and innovative ecosystem with many vendors including Amphenol, Comba, CommScope, Huawei, Kathrein and RFS all competing to include these advanced multi-antenna features,

“Advanced antenna systems including complex passive antennas and large scale massive MIMO active antennas will become part of the roadmap to advanced LTE and 5G,” concludes Marshall. “The need for active antennas when MIMO becomes more advanced will also change the market map, which has largely depended on passive antennas for previous generations.”

These findings are from ABI Research’s Evolution of MIMO in LTE Networks report. This report is part of the company’s Mobile Networks Infrastructure research service, which includes research, data, and analyst insights.
