As 5G is being rolled out, the demand for In Building Solutions (IBS) is growing significantly. Network design is moving inside because key 5G use cases focus on indoor usage. Typical 2-4G spectrum can penetrate structures, but the mm wave frequencies that deliver high speed/low latency 5G cannot.
From the beginning it was clear that upgrading a macro tower to 5G would not be sufficient to meet the data consumption demands 5G is there to facilitate. Infrastructure providers and MNOs have addressed this by investing in more numerous micro sites in high traffic areas by deploying outdoor small cells, mini-macro towers and smart poles.
