Network Deployment & Corporate Wi-Fi: coverage in Curitiba - PR

Voice and video change the design criterion

Real-time traffic makes a demand that downloads do not: predictability. A file that arrives with irregular delay arrives all the same; a call that arrives with irregular delay breaks up, because there is no waiting for the late packet.

In practice, three design decisions come to matter more than the contracted speed. The first is prioritization: voice and video need precedence over backups, updates, and file synchronization, which tolerate waiting. The second is the choice of medium — a fixed desk on frequent calls performs better on cable, because it eliminates the variation inherent to shared radio. The third is access point density, sized for how many devices talk at the same time, not for covering the floor plan.

Without these, the symptom is the most frustrating one possible: an excellent speed test and bad meetings, which leads the team to blame the videoconferencing tool.

The headset is part of the network too

A practical note: a good share of call-quality complaints in offices comes from wireless devices operating in the same saturated band, not from the link. Many audio peripherals use the 2.4 GHz band — the same one occupied by legacy Wi-Fi and by the equipment of the tenant on the next floor.

In a dense environment, moving workstations to 5 GHz and freeing up the 2.4 GHz band reduces that conflict. It is a configuration change, costs nothing, and resolves complaints that are usually treated as a vendor problem.

Corporate buildings: the infrastructure is not yours

An office in a leased building carries a constraint that owned premises do not: part of the infrastructure belongs to the building. The entrance facility where carriers land, the riser between floors, and sometimes the pathway up to the floor's own ceiling all follow someone else's rules.

That has concrete planning consequences. Work in common areas requires authorization and usually has a window defined by building management. Bringing in a second provider depends on there being an available path in the riser — a field verification, done before signing a connectivity contract, not after. Reversible installation is preferable, because the lease will require the space to be handed back.

The approach is to survey those conditions at the start: what belongs to the building, what requires authorization, what pathway exists, and what can be executed within the floor without depending on a third party.

Office layouts change more than industrial ones

Offices reorganize constantly: teams grow, areas get redivided, a room becomes open space, part of the team starts working alternate days, and actual occupancy drops below the number of desks.

A rigidly designed network ages with every one of those changes. The answer is to build in margin — cabled points at likely expansion positions, support infrastructure with free capacity, and a distribution that allows an access point to be moved without a new design.

There is an extra gain in this kind of environment: with variable occupancy, Wi-Fi sizing should be based on the real peak of simultaneous presence, which tends to be quite different from the total number of chairs. Measuring it avoids both undersizing and overspending.

Segments defined at design time

The deployment separates the corporate network from the guest network from day one, and puts equipment administration in its own segment. In clinical or laboratory environments, a segment for the instruments comes in as well — devices that rarely receive updates and therefore depend on isolation.

Doing this at design time costs configuration. Doing it later, on a flat network already in production, costs downtime — and in a corporate operation, downtime has a scheduled hour and witnesses.

The sectors that drive demand in Curitiba

Professional services, healthcare, technology, and education define the capital's profile. Professional services and technology concentrate demand on voice, video, and cloud access. Healthcare requires dependable coverage in treatment rooms and equipment segmentation. Education combines a high-density student network, an administrative network, and labs — three profiles that need to coexist without mixing.

How we run the deployment

It starts with a site visit and measurement, with the environment in use: how many desks exist, what the peak of simultaneous presence is, who spends long stretches on calls, which devices operate at the same time, and which neighboring networks occupy each channel.

In parallel, a survey of the building's conditions: what is common area, what requires management authorization, and what pathway exists in the riser. From that combination comes the design — access point placement, channels, power levels, cabled points, traffic prioritization, and the segment structure.

Execution proceeds in stages, keeping the current environment running until the new one is validated, and is scheduled outside operating hours. Closeout includes testing every point, verifying call quality at the desks that depend on it, and documenting what was installed — which is what lets the next expansion follow the same standard.
