Guest Wi-Fi in hotels: foreign guests, floor load, check-out

Hotel guest Wi-Fi differs from a café setup in three ways: guests stay for days rather than an hour, a good share of them come from abroad, and access is expected to close when the stay ends.

Those three differences drive the choice of sign-in method.

Guests from abroad

This is the most common sign-in problem in hotels. Texts to foreign numbers:

• Do not always arrive. Some country and operator combinations drop them.
• Cost more.
• Never reach a guest who has roaming switched off.

A guest with roaming off is precisely the guest who wants the hotel's Wi-Fi; sending them a text is a dead end.

Practical answer: keep SMS as the default but put two options beside it.

1. Vouchers. Reception hands out a voucher valid for the length of the stay at check-in. For foreign guests this is the smoothest method.
2. E-mail. The code goes to an e-mail address instead of a phone. Can the guest read e-mail while connected to the hotel Wi-Fi? Yes, if the portal is set to allow a handful of mail servers before verification.

Floor load

In a hotel, the number of concurrent devices runs at 1.5–2.5 times the room count. In a 100-room hotel, expecting 150–250 devices in the evening is realistic: every guest has a phone, and many also carry a tablet or laptop.

Plan capacity against that multiplier, not the room count. The peak is between 21:00 and 23:00; video streaming produces most of the day's traffic in that window.

Set a speed limit. A sensible ceiling per guest stops a few heavy users from slowing down a whole floor. The limit should be high enough not to annoy guests and low enough to protect the line.

Access after check-out

Wi-Fi access is not meant to continue after a guest checks out. Vouchers solve this naturally: the voucher is valid for the length of the stay and access closes when it expires.

With SMS you get a similar result by setting a session length, though tying it exactly to the check-out moment is hard. Full integration with a property management system is a separate project for businesses that want it.

The staff network must be separate

A hotel runs other devices alongside the guest network: reception computers, card terminals, door locks, the camera system, housekeeping tablets.

None of them belong on the guest network. The separation matters for two reasons: guest traffic should not eat their bandwidth, and guest devices should not reach those systems.

If fixed devices such as printers and card terminals do have to sit on the guest network, a MAC exemption keeps them off the sign-in screen.

Meeting and event rooms

Hotel meeting rooms create a different pattern: many short-lived users in a single day.

Producing vouchers in bulk is the practical answer. Before the event, print day-long vouchers and hand them to attendees. Making everyone wait for their own text is both slow and costly.

The welcome screen

The hotel portal is the first digital face a guest sees. A few things you can use without overdoing it:

• The hotel's logo and colours
• A short notice for breakfast hours, the spa or the restaurant
• A redirect to the hotel's own page after sign-in
• A brief satisfaction question on departure day

Keep it restrained. The guest wants to get online; the welcome screen should not last more than three seconds.

Setup order

1. Separate the guest network from the staff network.
2. Route guest traffic through the device at the network edge.
3. Turn on sign-in methods: SMS by default, vouchers and e-mail as backups.
4. Set speed and time limits.
5. Show reception the voucher screen and fit it into the daily routine.
6. Define MAC exemptions for fixed devices.
7. Test at peak hour with a real device — your own phone, in the furthest room, not the lobby.

The last item is the one most often skipped, and the one that causes the most trouble.
