DECT cordless deployment and coverage design is one of the most overlooked line items in a warehouse, healthcare, or retail voice rollout, and getting it wrong shows up fast as dropped calls and dead zones. This guide walks MSPs through the site survey process, multi-cell base station and repeater planning, and the network and power prep that has to happen before a single handset ships. It breaks down how coverage requirements actually differ across warehouses, hospitals, and retail floors, from ruggedization to RF considerations near patient telemetry equipment. You will also find a practical hardware shortlist, a troubleshooting list of the mistakes that generate callbacks, and where Viirtue's white label platform fits into a repeatable DECT deployment offering. The goal is a deployment MSPs can scope and quote with confidence instead of guessing at coverage after the fact.
