DECT cordless phones: coverage for the whole site, not just the desk

Warehouses, clinics, restaurants, and shop floors run on DECT. How the technology works, and how to plan coverage that doesn't drop calls.

Some jobs refuse to sit still. The pharmacist is at the dispensary shelf, the site manager is on the mezzanine, the maître d' is everywhere at once — and each of them still has to answer the phone. DECT cordless handsets from Yealink and Gigaset give these roles a full business extension that travels the building with them.

Why DECT and not just Wi-Fi?

DECT runs on its own dedicated radio band, completely separate from your Wi-Fi. Voice never competes with laptops for airtime, handoff between base stations is seamless mid-call, and battery life is measured in days rather than hours. It is older technology than Wi-Fi calling, and in dense environments it remains stubbornly better at the one job it does.

Planning coverage that holds a call

  • A single base station covers roughly 50 metres indoors — walls, racking, and cold rooms all shrink that figure.
  • Multi-cell systems let handsets roam between base stations mid-call; plan overlapping cells rather than islands.
  • Do a walk test before committing: carry a handset on a live call through every corridor, stairwell, and yard you expect it to work in.
  • Metal shelving and lift shafts are the classic dead-zone culprits — a warehouse usually needs a base station per aisle block, not per floor.

One extension, wherever the handset roams

On RingPlus a DECT handset is a full extension: it appears in ring groups, pulls the shared directory, records calls if its user's policy says so, and hands off to the mobile app when someone leaves the site entirely. The kitchen porter's handset and the director's desk phone live in the same system, with the same rules.

A dropped call in a warehouse aisle is not a radio problem, it is a planning problem. Walk the site with a handset before you screw anything to a wall.
