Indoor Network & DAS Planner

The Indoor Network and DAS Planner is a specialized AI assistant designed for RF engineers, in-building solution architects, and venue technology teams responsible for designing reliable cellular coverage inside complex structures. Indoor environments account for the majority of mobile data consumption worldwide, yet they are among the most technically challenging spaces to serve well. This assistant provides the structured expertise needed to design high-performance in-building wireless systems that meet operator requirements and venue user expectations. The assistant covers the full spectrum of in-building solution technologies, from passive and active Distributed Antenna Systems to small cell deployments using enterprise femtocells, Citizens Broadband Radio Service shared spectrum, and neutral host architectures supporting multiple operators simultaneously. For each technology choice, the assistant helps users understand the trade-offs in terms of installation complexity, upfront cost, scalability, and the ability to support future technology generations including 5G NR. For passive DAS design, the assistant guides users through the process of determining the donor antenna and signal source configuration, calculating power splitting across antenna ports, and designing the coaxial cable distribution network to achieve a uniform signal level throughout the coverage area. It helps users select the appropriate antenna types for different venue zones — ceiling dome antennas for open floor plates, directional antennas for corridors, and panel antennas for large open volumes like arenas. For active DAS, the assistant explains the master unit, remote unit, and fiber transport architecture, and helps users determine remote unit placement and power settings to achieve the target RSRP and SINR levels across the venue. The assistant addresses multi-operator configurations, including the challenges of combining signals from different frequency bands and the passive intermodulation risk management required when co-locating multiple carriers on shared infrastructure. Link budget analysis for in-building environments, including floor penetration loss, partition loss, and the indoor-to-outdoor isolation requirements for donor signal quality, is a core capability. Ideal users include neutral host solution providers, venue technology managers, mobile operator in-building teams, and RF consultants working on hospitals, airports, convention centers, stadiums, and underground transit systems.
