For in-building wireless, success depends on understanding what mobile network operators want. This session examines MNO roadmaps for indoor coverage and capacity, including spectrum priorities, preferred signal sources and carriers’ willingness to fund in-building systems. Carrier representatives and industry experts will discuss when operators will participate in a project, how they evaluate venues, and what alternatives exist when carriers won’t pay, including neutral-host and owner-funded models. Attendees will gain insight into carrier decision-making and practical guidance for aligning in-building projects with MNO requirements, helping them structure deals that get signal sources committed and systems turned on.
