Modernisation of IT infrastructure in a small company - case study
Modernising the IT infrastructure in a small company did not start with choosing a router. It started with determining what eight workstations, several printers and the server with the ERP system were actually working on, since the Internet was regularly disconnected, there was no Wi-Fi, and no one had a full picture of the network. We show the existing condition, the scope of work performed and the project boundaries without providing the client's name and without adding results that we did not measure.

Rack cabinet in a small company: what should it contain
In a small company, a rack is a distribution point that provides access to the network, devices and documentation, not a storage space for equipment. This article shows you how to plan its contents, power supply, cooling, physical access and development space so that every subsequent change does not start with untangling cables.

PoE in the enterprise network: switch power budget
One cable instead of two is the greatest advantage of powering over Ethernet and at the same time the source of the most common mistake when shopping: assuming that all PoE is the same. This article explains how the standards differ, how to calculate the PoE power budget for a switch and how to know when it has run out.

Roaming Wi-Fi: why the phone keeps a weak signal
The phone passes through the office, past two access points with a strong signal, and then sticks to the third, weakest one. This is not a bug, but the way Wi-Fi roaming works in the company: the decision is made by the client device, not the network. This article explains the mechanism, shows what can be done about it on the network side, and says directly what cannot be done.

Cat6 or Cat6A in the company: where is the decision threshold?
Cat6 or Cat6A is a decision about a spare for several years, not about which cable is better. This article shows where the real threshold is between them, why the cable itself is not the entire track and when the price difference is not worth it.

Wi-Fi for hotel and guesthouse: what is different
Wi-Fi for hotel and guesthouse is part of the service sold, not supporting infrastructure. This changes requirements in five places at once: placement, login, operational network separation, guest service, and maintenance. This article describes each of them.

How to prepare your company for network valuation
Preparing for a network valuation comes down to a few simple things that shorten the entire process and make it more accurate, and none of them requires knowledge of the network. This article collects them into a checklist, explains the importance of each point and shows why an inaccurate quote may result in an annex.

Firmware updates of network devices in the company
Firmware updates for network devices bring bug fixes and security gaps, but each of them means a restart, i.e. a break. This article describes how to plan your service window, what order to update, when to consciously wait, and why it's a recurring, not a one-time, activity.

Questions for the network contractor before signing the contract
Good questions for the network contractor, asked before the contract, save more than many price negotiations, because they reveal what exactly the order is about. This article collects them in six areas and explains in each one why they should be asked and what should be disturbing in the answer.

Remote corporate network management: how it works
Remote management of the company network means you don't have to be on site to see what's happening there. This article explains the difference between a cloud panel and a VPN connection, what can and cannot be seen remotely, who should have such permissions and why it is the foundation of multi-location support.

Network acceptance protocol and as-built documentation
The network installation acceptance protocol is not a formality, but a document that states exactly what was done, tested and handed over. This article describes what it should contain, what is the difference between a continuity test and a certification measurement, and what must remain in the company after the work is completed so that the network is not dependent on the contractor.

Wi-Fi in the hall and warehouse: why shelves attenuate the signal
Wi-Fi In a warehouse, different rules apply than in an office, because metal shelves and variable merchandise layout reflect and attenuate the signal in a way that cannot be predicted from behind the desk. This article explains why the hall behaves differently, why adding access points usually does not help and what exactly changes the on-site measurement.

How to secure your corporate network: four basics
The question of how to secure a corporate network is not answered in one purchase, but in four things done in the right order: know what is on the network, divide it, organise administrative access and update devices. This article describes each of them, points out what they don't do, and says directly which of them require constant supervision.

How many access points are needed in the office?
There is no conversion factor from square metres to the number of access points, so the question of how many access points an office really needs is resolved differently. The result depends on the number of devices, the arrangement of partitions and what this network has to carry. This article shows which dimensions actually determine why adding equipment can make the situation worse and what to prepare to make the selection make sense.

Network modernisation in an active company without downtime
Modernising your corporate network without downtime is more a matter of sequence and contingency plan than the hardware itself. This article describes what to determine before work, how to limit the break technically, when a break is inevitable and why we do not specify the number of days in advance.

Router from the operator and managed corporate network
It's not a choice between two devices from the same shelf. A router from the company's operator provides the Internet to the building, and the managed network allows you to control what is happening inside. This article shows what exactly the management layer changes, when the operator's equipment is completely sufficient and how to know when it stops.

Corporate network running slow? How to diagnose the cause
"Network is slow" is a symptom, not a diagnosis. A slow network in a company is caused by one of three layers, so before you replace the router or buy access points, it is worth determining in which of them the problem actually occurs. This article walks you through a sequence that saves you money: from clarifying the symptom, to separating the layers, to when purchasing equipment makes sense.

Ubiquiti UniFi for companies: opportunities and limitations

Remote and on-site IT support: how it works in practice
The question "are you coming to us?" comes up in almost every first conversation, and remote and on-site IT support is a more useful answer when it is broken down into parts: what can be done remotely, what requires on-site presence and who organises it. This article describes our model without beating around the bush, including what we don't promise.

SLA IT: what is the difference between response time and repair time
A 15-minute response sounds better than a 4-hour response until you see what happens after those 15 minutes. An SLA does not promise that the outage will disappear quickly. It promises that you always know what is happening with it.

A small company is increasingly based on everyday work on computers, the Internet and applications. One failure in the system can paralyse sales, customer service or accounting for hours. Meanwhile, maintaining your own IT department can be costly and requires continuous recruitment and training. The solution that many micro and small enterprises choose is IT outsourcing, that is, entrusting IT services to external specialists.

One IT partner or multiple suppliers? Model comparison
