Guest Wi-Fi, POS system and back-office network kept apart, and properly connected.
A hotel or restaurant runs guest Wi-Fi, a point-of-sale system, payment terminals and booking software at the same time, often across several floors and thick period walls. NDVDL designs and builds the network and IT infrastructure that carries all of it.

How do you keep guest Wi-Fi properly separated from the POS system in a hotel or restaurant?
Guest Wi-Fi belongs on its own VLAN with a captive portal, technically separated from the network carrying the point-of-sale system, payment terminals and back-office systems, so guests reach the internet and nothing else on the premises. NDVDL sets this separation up at firewall and switch level, not just with a second password on the same network. That also narrows the liability question for the operator, since the guest network stays isolated from the rest of the business. For hotels and restaurants in Vienna, Lower Austria and Slovakia, NDVDL builds this separation as part of network planning and firewall work.
What actually goes wrong in hotels and restaurants
Four patterns that keep showing up in hotels, guesthouses and restaurants.
One network for everything
Guests, the POS system and the office computer often share the same network because a single router covers the whole building. When guest Wi-Fi buckles under many simultaneous connections, it frequently takes the till with it.
Dead spots behind thick walls
Period buildings and listed properties have walls that block Wi-Fi signal, especially on upper floors or in cellar rooms. Guests complain about reception, while running a cable for another access point is often restricted for heritage reasons.
Payment terminals with no network of their own
Card terminals often sit on the same network as guest Wi-Fi or office PCs, because nobody thought about separation when they were installed. That is a security risk and makes it harder to isolate exactly which device is affected if something goes wrong.
Access rights nobody tracks anymore
Seasonal staff get logins for the POS system, Wi-Fi or booking software that are never withdrawn once the season ends. Over the years, access accumulates that nobody can trace back to an active person.
Infrastructure that carries the business
Six pieces NDVDL puts in place to bring order to network and IT in hospitality.
Network planning for rooms, kitchen and reception
NDVDL plans the network by area, so guest rooms, reception, kitchen and storage each get their own network segment. That way a fault in one area stays contained to that area.
Firewall with a dedicated guest VLAN
Guest Wi-Fi runs on its own VLAN with a captive portal, technically separated from the POS system, back office and payment terminals. The firewall governs which device is allowed to talk to which network.
Wi-Fi coverage across multiple floors
NDVDL positions access points so upper floors, cellars and dining rooms behind thick walls still get reliable coverage. In listed buildings, cabling is planned to avoid visible intervention in the fabric of the building wherever that is possible.
Connecting POS, PMS and channel manager
NDVDL connects the point-of-sale system, property management system and channel manager cleanly into the network, including the separation needed around guest areas. Existing systems are integrated rather than replaced.
Camera coverage for entrances and storage
Camera systems for entrances, storage and outdoor areas are planned so dining rooms and staff areas stay out of view. Camera placement follows what is actually permitted under data protection rules.
Ongoing IT support through the year
Network, POS system and server room get ongoing support, not just a one-off setup. That includes remote maintenance, backed up by on-site visits in Vienna, Lower Austria and Slovakia.

What projects look like in practice
Three ways NDVDL's work in hospitality typically takes shape.
Opening a new boutique hotel
A hotel about to open needs network design, Wi-Fi coverage and the connection of PMS and POS built from scratch. NDVDL plans the infrastructure before the fit-out, so cable routes and access point locations are considered from the start.
Retrofitting a listed guesthouse
An existing business in a historic building needs better Wi-Fi on upper floors without opening up the structure. NDVDL assesses on site which cable routes are feasible and plans access points accordingly.
Separating guest network and POS during live operation
A restaurant or hotel still runs guest Wi-Fi and the POS system on the same network and wants that separated without closing. NDVDL implements the separation through firewall and VLAN changes, keeping disruption for guests and staff to a minimum.
