Fibre at 835 m: why connectivity is not the compromise

Yes, Foncine-le-Bas has fibre: the house has a 1 Gbit/s line. The first objection to a mountain work retreat falls quickly, at least for laptop work. For mobile phones, it helps to know where the signal comes from, which is what this page covers.
The first objection
Before anyone books, the same question comes first: what about the network? The worry is fair. A small village with forest on every side: you picture a client call dropping at the worst moment. The answer is one word: fibre. An optical line runs to the house, fixed infrastructure of the kind cities get, laid where nothing else around resembles a city.
What the line lets you do
The number matters less than what it carries. A line of this capacity lets a team video call run, cameras on, while someone else sends a heavy file. A screen-shared workshop, a live demo, a link back to headquarters: what a team expects from an office, the line allows. We do not publish a measured speed; if a use case looks borderline to you, tell us before you book.
Mobile phones, plainly
According to ANFR open data, no mobile mast stands in the commune itself: the mobile signal comes from neighbouring villages. Neighbouring Foncine-le-Haut is 6 km away by road, and all four operators, Orange, SFR, Bouygues Telecom and Free, have 4G and 5G antennas there. In a wooded valley, though, reception varies from room to room and from one operator to another. Before you come, check the ARCEP « Mon réseau mobile » map for your operator, and turn on wifi calling on your phones: with fibre, that is the safest option for an important call.
Doors for your calls
Bandwidth settles only half the problem; the other half is privacy. A call that matters wants a door that shuts, and that is the whole gap between a house and a hotel floor. The 3 bedrooms and the study give as many rooms to step away into, then everyone regathers at the long table. The line belongs to your team alone, like the house. Two simple habits make the week calmer. Everyone brings a headset with a microphone, so that calls do not carry from one room to the next. The team also sets meeting-free hours, in the morning for instance, when nobody takes a phone call in the main room.
Preparing a working week
A few habits prevent surprises: a network cable for the laptop that hosts the video calls, updates run before leaving rather than on site, and a shared call schedule so that three meetings do not land at the same time. For a team coming from Switzerland, the drive from Geneva describes the arrival; to plan the days, the Monday-to-Friday week suggests a running order.
