However, the path to widespread adoption of in-building wireless solutions has challenges. Providers must address issues such as the need for scalable, reliable coverage in complex environments, diverse building architectures, and the growing demand for high-bandwidth, low-latency connectivity to support next-generation applications. Additionally, the high costs and complexity of network installation and upgrades complicate widespread adoption. To overcome these challenges, vendors have developed innovative solutions. For example, Ericsson 's Radio Dot, a neutral host system, has been approved by major U.S. carriers and already provides flexible coverage in dense, high-traffic environments like airports. Similarly, Nokia 's AirScale portfolio enables operators to deploy future-proof private 5G networks that support advanced technologies like mmWave, IoT, and automation.
