Cellular vs. Landline Telephone Entry: Which Should You Choose?
For most new telephone entry system installs today, cellular connectivity has become the practical default, and a landline-dependent system is increasingly the exception rather than the norm. But understanding why — the actual call path, the cost structure, and what code requires either way — makes the choice clearer than just following the trend.
Cellular is the more practical default for nearly any new telephone entry system install, because it skips running a dedicated phone line and reaches the resident’s cell phone wherever they are — but landline still makes sense if a property already has an active line in place and avoiding a recurring service cost matters more than that flexibility. The two differ in how the call physically reaches you (a wired line into the house vs. a cellular radio in the call box itself) and in cost structure (a landline system is closer to a one-time install, while cellular systems typically carry an ongoing plan cost similar to a cell phone bill). One thing that doesn’t change: code requires the call box itself to sit at least 6 ft from the gate, out of its reach, with a full view of the gate — regardless of which connectivity type is behind it.

The real difference: how the call reaches you
Both landline and cellular telephone entry systems do the same basic job: a visitor at the gate reaches the resident by phone, and the resident decides whether to grant access. What differs is entirely in how that call physically travels. A landline system rings into the house over a dedicated phone line run from the gate — reliable, but only reachable where that handset actually is, and it requires that line to exist in the first place. A cellular system puts a cellular radio in the call box itself, connecting straight out to the resident’s cell phone wherever they happen to be, the same way any cell call would. Neither technology changes the underlying access decision — see our page on what a telephone entry system is and how the call flow works for that part.
Landline vs. cellular telephone entry, side by side
| Landline | Cellular | |
|---|---|---|
| How the call reaches you | Over a dedicated phone line run to the house | Direct to the resident’s cell phone/app, wherever there’s coverage |
| New install requirement | Running a dedicated phone line to the gate | A confirmed cellular signal at the gate location |
| Typical cost structure | Closer to a one-time hardware/install cost | Hardware cost plus an ongoing service/data plan, similar to a cell phone bill |
| Best fit | A property with an existing landline already run for this purpose | Most new installs, especially where no landline already exists |
| Call-box placement rule | Same either way: ≥ 6 ft from the gate, full view of the gate (DASMA TDS 353 / #352) | Same either way: ≥ 6 ft from the gate, full view of the gate (DASMA TDS 353 / #352) |

Landline or cellular: which fits your gate?
Answer three questions about your property to see which connectivity type the factors above actually point to. This doesn’t replace a site visit — it just applies the same reasoning in the sections above to your specific situation.
Based on the connectivity factors described on this page. The 6 ft call-box placement rule (DASMA TDS 353 / DASMA #352) applies the same either way and isn’t part of this check.
