U.S. IBW Forecast, 2020 – 2025: Supporting Commercial Buildings and Manufacturing Facilities

Indoor small cells and in-building wireless (IBW) systems are deployed in commercial buildings and manufacturing facilities to provide a secure network and improve the experience of employees and guests indoors. They are also used to support industry-specific use cases, such as online concessions in smart stadiums and ultra-reliable and low latency automated applications on the factory floor.

IBW systems use many types of indoor small cells, including Distributed Antenna Systems (DAS), DAS Lite, picocells or enterprise small cells, femtocells and cellular signal boosters.

This market study provides a five-year forecast for spending for in-building wireless systems in U.S. commercial buildings and manufacturing buildings. iGR found that due to the pandemic, the IBW market for 2020 and beyond is significantly different than it was previously. This revised forecast was modeled with:

  • New data and assumptions regarding the (ongoing) COVID-19 pandemic
  • Newly available data (November 2020) from the Commercial Buildings Energy Consumption Survey (CBECS)
  • Information gathered from conversations with multiple solution providers in the IBW market.

Included in the market study is a five-year forecast for both network build spending and operational spending for the deployment of cellular IBW in U.S. commercial and manufacturing buildings in the sub 6 GHz, CBRS, and mmWave bands.

Note that this market study provides separate spending amounts for commercial buildings and manufacturing buildings, but it does not provide spending breakouts by types of commercial buildings, such as retail, healthcare, stadiums, and transportation buildings, nor does it provide spending breakouts by types of manufacturing facilities. This detailed spending can be found in iGR’s Enterprise 5G series of building-specific market studies.
