Network & Wi-Fi

Network and Wi-Fi that simply work – today and at the next refit.

We plan, cable and look after your network: from the socket on the wall and the Wi-Fi to a secure connection for working from home.

Why is a well-planned network so important?

The network connects all devices, servers, printers, phones and the internet connection. If it is poorly planned or the cabling is a tangle, the result is slow connections, outages and security gaps. A cleanly planned and documented network runs reliably and is easy to extend.

We rely on careful planning, tidy, labelled cabling and documentation that makes every later change quick to carry out. For new offices, law firms and medical practices, we coordinate directly with the architects, electricians and other trades.

Scope of services

What we do for your network

Planning & cabling

  • Needs planning for workstations, printers and phones
  • Structured, labelled cabling
  • Network cabinets, patch panels and switches
  • Documentation with plan and port assignment

Wi-Fi

  • Site survey: full coverage instead of dead spots
  • Centrally managed access points
  • Separate guest Wi-Fi
  • Wi-Fi for large sites and outdoor areas too

Security & remote access

  • Network segmentation (VLANs) as standard
  • VPN for working from home and on the move
  • Connecting several office locations
  • Monitoring of the key components

Internet & more

  • Advice on and ordering of internet connections
  • Failover with a second line
  • Video surveillance and access control
  • Integration of the phone system and e-card line (Austrian health insurance network)

Standard with us

Network segmentation – even for small networks.

In many offices, every device sits in one single network: PCs, servers, printers, phones, the guest Wi-Fi, sometimes cameras and smart TVs. If one device is compromised – by a phishing email or an outdated printer – the attacker can reach everything else from there.

That is why we split every network into separate zones (VLANs) as standard, also for small businesses, law firms and medical practices. A firewall between the zones decides who may talk to whom: the guest Wi-Fi only reaches the internet, the printer cannot reach the server, and an infected PC cannot reach the backups.

  • Contains attacks: ransomware cannot spread unhindered
  • Protects servers and backups from infected devices
  • Isolates insecure devices: printers, cameras, IoT
  • Guests and private devices stay outside
  • Clearer network, easier troubleshooting
Your network isn’t segmented?“My IT provider says we don’t need VLANs.” – Let’s talk about it. We’ll show you what segmentation would look like for your network; the initial consultation is free.Have your network checked

Typical occasions

When we get called in

  • New office, new medical practice or a move
  • Wi-Fi drops out in some rooms
  • The network has “grown” over the years and nobody knows the cabling
  • Staff need to work securely from home
  • A second site needs to be connected
  • The internet goes down and work grinds to a halt

In brief

What is a VPN?

A VPN (virtual private network) is an encrypted connection over the internet into the company network. Anyone working from home or on the move can access servers and programs as securely as if they were sitting in the office.

A VPN replaces insecure solutions such as remote access that is reachable directly from the internet – one of the most common entry points for attacks. Read more under IT security.

Typical problems

Cause and solution at a glance

Woman shrugging in frustration at her laptop

Slow Wi-Fi or dead spots

Common cause

Too few or poorly placed access points

Solution

Site survey and centrally managed Wi-Fi

Network cables plugged into a switch

The whole network is slow

Common cause

Outdated switches, incorrect cabling, bottleneck at the internet connection

Solution

Measurement, replacement of individual components, a suitable connection

Server rack with a red warning light

Everything stops when the internet is down

Common cause

Only one line, no failover

Solution

Second line or mobile backup

Tangled cables in a network cabinet

Nobody knows the cabling

Common cause

Missing labels and documentation

Solution

Inventory, labelling, network plan

How we work

From planning to a reliable network

  1. Site visit

    We look at the rooms, existing equipment and requirements on site – for new buildings, based on the plans.

  2. Planning

    You receive a plan covering cabling, Wi-Fi, components and costs.

  3. Implementation

    We cable, install and configure – coordinated with the other trades.

  4. Documentation & support

    You receive complete documentation, and we continue to monitor and look after the network.

Moving or setting up

Involve us early in the planning.

For new offices, law firms and medical practices, we save time and money when we are involved from the room-planning stage. We plan the network, IT and phone system together and coordinate directly with the architects and electricians.

FAQ

Questions about Network & Wi-Fi

Can’t find your question? Call us on +43 1 2266 2260.

What does a business network cost?

That depends on the number of workstations, the size of the premises, the Wi-Fi you need and whether new cabling is required. After a site visit, you receive a quote covering all components and work.

Why is my Wi-Fi so poor in some rooms?

Usually because there are too few or badly placed access points, thick walls or interference from neighbouring networks. A site survey shows where additional access points are needed.

What is network segmentation?

Network segmentation splits a network into separate zones (VLANs), for example for workstations, servers, telephony, printers and devices, and guests. A firewall decides which zones may communicate with each other. If one device is attacked, the damage stays confined to its zone.

Do small networks need VLANs too?

Yes. Attacks do not care about company size, and small networks in particular often have printers, cameras or private devices in the same network as servers and backups. With modern network equipment, segmentation is easy to set up even for a handful of workstations – which is why we implement it as standard for all our clients.

My IT provider says we don’t need VLANs. Is that true?

A network without segmentation works – until one device is compromised. Then the whole network is open to the attacker. We are happy to look at your network and show you what segmentation would look like for you.

Do I need a separate guest Wi-Fi?

Yes. A separate guest Wi-Fi lets visitors onto the internet without giving them access to your servers, printers or patient and client data.

What is structured cabling?

Structured cabling means that all cables are laid according to a uniform system, brought together in a network cabinet and labelled. This makes changes and troubleshooting much faster.

Can several sites be connected?

Yes. With an encrypted site-to-site connection (site-to-site VPN), several offices or medical practices work as if they were on one shared network.

Do you also take care of the internet connection?

Yes. We advise on the choice, order the right connection and set it up. For businesses that come to a standstill without the internet, we recommend failover via a second line or mobile connection.
