WiFi site survey in Cologne.

Cologne has an unusual spread of building types for wireless planning. Older masonry buildings in the centre absorb signal and often have restrictions on drilling, while converted warehouses along the Rhine combine brick, steel and large glass areas that reflect it. Modern media campuses add open studios, glass meeting rooms and edit suites where many devices compete for airtime. A predictive model gives a useful first budget, but in a building with mixed construction an on-site measurement usually shows what the drawings cannot, such as a lift shaft or a dense wall that cuts a floor in half.

Industry shapes the demand as well. Production and broadcast teams often use wireless equipment that competes with office WiFi, so interference needs to be measured rather than assumed. Insurers moving to flexible desks need dependable coverage across large open floors, and the trade fair district and hotels deal with crowds that arrive in waves. We usually recommend a validation survey after installation, timed outside event periods where possible, so that the results reflect a normal working day and the access points are tuned before staff rely on them. The report then lists any changes by access point and location.

Cologne's IT estate reflects a city built around media, insurance, trade fairs and industry along the Rhine. Broadcasters and production companies run studios and edit suites, insurers keep large office floors and back-office systems, and chemical and automotive firms in the wider region run plants and logistics sites that depend on reliable networks. Much of this is spread across sites: a headquarters or studio in the city, warehouses and plants in surrounding towns, and equipment held in colocation facilities in Cologne or in the larger Frankfurt market a journey away. IT teams are often lean, so physical work tends to be planned and documented.

Geography and the calendar shape the work. The Rhine divides the city, and crossing between the two banks can be slow at busy times, particularly around the trade fair grounds in Deutz when large events are on. Carnival season brings road closures and restricted deliveries in the centre, and building managers often ask contractors to avoid those days. Premises range from older masonry buildings in the centre to converted harbour warehouses and modern media campuses. Business is done in German and English, so site paperwork is often German while work notes are written in English. For work in Cologne we line up local engineers who know these conditions and keep one manager as your single contact.
