U.S. Outdoor Small Cells Forecast, 2016-2021: Moving toward the Cloud

iGR believes that outdoor small cells will be an integral part of mobile operator networks. However, the outdoor small cell market is still in the beginning stages of deployment. The main barriers have little to do with the technology itself and more to do with actual installation issues – power, backhaul, regulations, timelines, and overall cost.

The vast majority of the cost of an outdoor small cell is related to providing everything except the actual “small cell” – which iGR defines as either a metrocell, RRH deployed as a small cell or an outdoor DAS (oDAS). Definitions follow in the body of the report.

Accessible sites – actual, physical locations – are the scarcest resource with respect to small cell installation. There are only so many poles, building sides and roofs in a given area, and there is only so much useable space on them. Using that space comes at a premium.

In general, these various issues, among others, have conspired to slow down the deployment of small cells by U.S. operators. However, iGR believes that small cells – and many of them – are inevitable, particularly as carriers march quickly down the road to 5G. In short, the industry cannot meet the demand for mobile data without small cells.

In this market study, iGR presents a total addressable market forecast and an “actual” forecast for U.S. outdoor small cell nodes installed: metrocells, remote radio heads as small cells and outdoor DAS.

The assumptions underlying iGR’s outdoor small cell forecasts are explained in this market study. The forecasts are further based on iGR’s global connections forecast market study and iGR’s mobile data forecast market study, as well as iGR’s primary and secondary research, and various other sources.
