The figure missing from Caldes de Montbui's profile

One in four people lives outside the town centre

According to the Idescat gazetteer at 1 January 2025, of Caldes de Montbui's 18,554 inhabitants, 4,862 don't live in the main town: 1,935 in Can Valls i Torre del Negrell, 1,672 in els Saulons i la Finca Ribó, 215 in els Lledoners and 1,042 in scattered rural homes. That's 26% of the municipality, and it's the real starting point for talking about connectivity and security here.

Seven residential estates, 39 farmhouses and cameras at the entrances

The Consell Comarcal counts seven residential estates in the municipality: Font dels Enamorats, Can Valls, Can Maspons, La Vall, Torre Negrell, Els Saulons and El Farell. On top of that there's the rural land: the Town Council lists 39 farmhouses and rural houses on non-developable land, and the municipality stretches as far as the village of Sant Sebastià de Montmajor, between Gallifa and el Farell. Homes here are also the largest of any area we work in: according to the 2021 census, 26.4% of the 6,603 main residences exceed 120 m², and 1,105 homes (14.3% of the housing stock) are not main residences. In February 2017 the Town Council increased the number of municipal cameras at the entrances to the residential estates to six (Can Maspons, els Lledoners, el Negrell, Can Valls and la Font dels Enamorats), with the stated aim of deterring crime and speeding up the police response to burglar alarms. Those cameras watch the entrance to the estate; what happens inside each plot is still down to each owner.

Mesh, radio link or Starlink, depending on the plot

These figures can't tell you which operator reaches each street or each farmhouse, and we're not going to make it up. What they do describe is a type of installation: a large house on a plot, sometimes empty for part of the year, and in the scattered rural areas with the network connection a long way off. What works there is measuring before buying: mesh Wi-Fi when the problem is spreading the signal across several floors and the garden, a point-to-point radio link or a Starlink installation when the problem is that the connection doesn't reach, and security cameras with phone alerts when the house is left empty. The same goes for businesses and working farmhouses.

On the ground

What working in Caldes de Montbui is like

On Caldes's residential estates the typical house is large: according to the 2021 census, almost half of the municipality's main residences are over 90 m². That means several floors, a garage and a garden, and an operator's router that only covers the entrance. Before proposing anything we measure coverage room by room, and that map decides whether a couple of access points will do or cable needs to be run.

The La Borda industrial estate, next to the C-59, covers 52.98 hectares and is home to most of the municipality's industry: leather and tanning, metalworking and plastics. Since February 2026 it has been undergoing works, with a €1.09 million project (sewers, pavements, dropped kerbs and resurfacing) paid for by the Diputació and the PUOSC. These are street works: the internal network in each unit, the office Wi-Fi and the perimeter cameras are still each business's responsibility. On the same estate is Caldes Emprèn, the municipal business incubator with offices, small units and coworking, where a newly created company needs the basics done right from day one: backups, professional email and computers that don't let you down.

And then there's the spa town. The water of the Font del Lleó springs out at over 70 °C, the Roman baths (Termes romanes) are a Bé Cultural d'Interès Nacional, and in 2025 Idescat counted four hotels with 350 beds, a campsite with 516 pitches and two rural tourism establishments. In a hotel or a spa, Wi-Fi is part of the service: a guest network separate from the management network, coverage in the rooms and a backup internet connection so the card terminal and bookings don't depend on a single line.

FAQs

About Caldes de Montbui

How long does it take to get from Granollers to Caldes de Montbui?+

About 25 minutes by road: 14.4 km between the two town halls via the C-1415 and C-59, according to the route planner we use to organise call-outs (with no traffic it's just over 22 minutes, and we round it up). The call-out is included, just as in Granollers. When the problem is software (a reinstall, an antivirus, a network setting) we often don't even need to travel: we sort it remotely. For network, camera, radio link or Starlink installations we do come in person, to the town centre, the residential estates and the La Borda industrial estate alike.

Do you cover the residential estates, such as Can Valls, els Saulons or els Lledoners?+

Yes, and in Caldes they make up a large part of the municipality: according to the Idescat gazetteer at 1 January 2025, 1,935 people live in Can Valls i Torre del Negrell, 1,672 in els Saulons i la Finca Ribó and 215 in els Lledoners. The Consell Comarcal also lists Font dels Enamorats, Can Maspons, La Vall and El Farell. These are large houses on plots, where the Wi-Fi typically doesn't reach the upper floor, the garage or the garden. We solve it with mesh Wi-Fi or with cabling, after measuring the coverage, not by switching operator blindly.

What options are there for a farmhouse or a scattered rural property in Caldes?+

According to Idescat, 1,042 people live in scattered rural settlements, and the Town Council lists 39 farmhouses and rural houses on non-developable land; the municipality stretches as far as Sant Sebastià de Montmajor, between Gallifa and el Farell. There's no public source saying which operator reaches each farmhouse, so we're not going to claim one. What we do is check at the specific address and, if the connection doesn't reach or falls short, propose a point-to-point radio link where there's line of sight, or Starlink. Sometimes the two are combined for backup, especially if there's a business operating from the farmhouse.

Do you work with businesses on the La Borda industrial estate?+

Yes. La Borda is Caldes's large industrial estate (52.98 ha, next to the C-59), and the other is El Pinatar (4.85 ha), home to small workshops. According to Idescat, in June 2026 there were 606 employer accounts in the municipality and 1,430 general-scheme registrations in industry. For an industrial unit we set up the internal network and Wi-Fi for office and warehouse, perimeter and access cameras, backups and support when a machine fails. The works that began on the estate in February 2026 (sewers, pavements, dropped kerbs and resurfacing) change none of that: the network inside each unit is down to each business.

I have a second home in Caldes. What do you recommend for keeping an eye on it?+

According to the 2021 census, 1,105 homes in Caldes (14.3% of the housing stock) are not main residences, and many are on residential estates. The Town Council has had cameras at the entrances to several of them since 2017, but they watch the entrance, not your plot. For a house that stands empty for long periods, what works is combining cameras with phone alerts and a connection that doesn't depend on someone being there to restart the router. We help you decide between an alarm or a camera, work out how many you need and make everything accessible from your phone. And if it's not a second home but your house or your business, that too: we serve home users, shops and businesses.

«Llevamos ya varios años trabajando con Thrax y la verdad es que estamos súper contentos. Nos gestionan la web, el programa de facturación y todo el tema de SEO, y el cambio se nota mucho.La web la dejaron limpia, rápida y fácil de usar tanto para nosotros como para los clientes.
El programa de facturación lo tienen muy bien montado: es intuitivo, nos ahorra un montón de tiempo y no hemos tenido ni un solo problema con las facturas ni con Hacienda.
En SEO también están haciendo un gran trabajo; hemos empezado a subir posiciones y a recibir más visitas orgánicas sin tener que preocuparnos nosotros.
Lo mejor es que responden rápido, son claros y se nota que saben lo que hacen. No es solo que cumplan, es que se involucran y proponen mejoras.
Sin duda los recomendaríamos a cualquiera que busque un equipo serio y profesional.»
