Calzavara and Desall invite you to participate in a new contest dedicated to the design of a telecommunications structure, which combines its primary function with elements of urban furniture and ambient intelligence services.

Company description

Calzavara is an Italian company renowned globally for revolutionising the concept of telecommunications infrastructure. With a legacy spanning over 50 years, Calzavara has consistently led the industry by transforming traditional telecommunications structures into architectural masterpieces that seamlessly blend functionality with aesthetic appeal. From the outset, the company’s vision has been to integrate telecommunications structures harmoniously into urban landscapes, thereby revolutionising the concept of connectivity. Today, Calzavara stands at the forefront of innovation, spearheading the development of multifunctional structures designed to accommodate not only antennas but also a comprehensive array of enabling technologies for the Smart City. This commitment to excellence, coupled with Italian design elegance and unwavering engineering innovation, forms the cornerstone of Calzavara’s success as it continues to shape the future of telecommunications infrastructure worldwide.

The brief is available in the following languages:
- English

What we are looking for

Calzavara is looking for fresh concepts and designs for multifunctional urban furniture structures. These structures will house mobile phone antennas and other radio devices while also functioning as attractive and/or functional aspects.
The “macro” mobile cell phone antennas will always be at the top, while the radio devices will typically be put in an accessible area near the base (lower section).
Given the structure’s urban destination, the remaining parts can be designed to host ambient intelligence services such as cameras, advertising or informational LED screens, advertising decorative elements (e.g., banners), lighting, electric charging for cars or scooters, and urban furniture elements such as benches, bicycle racks, and so on.


To ensure the proper development of your projects, carefully consider the following guidelines:

Project type

You are invited to create a multifunctional urban structure that will house mobile telephony antennas. The antennas can be hidden inside the structure or made apparent as part of its design. Please refer to the downloadable Material files for examples of multifunctional urban constructions, as well as antenna and radio device dimensions.
Style and aesthetic
The new structure must be innovatively designed, with a modern aesthetic fit for urban installation and global dissemination. The construction must be essential, taking into account the cost of the resources that will be used to build it.
The structure may incorporate the aesthetics of urban furniture (such as a streetlight pole) or a single ornamental piece (such as an “urban sculpture” placed along an avenue, in a garden, or in the centre of a roundabout).
There are already buildings in the firm inventory that resemble trees, such as pine trees, palms, and cypresses. As a result, such solutions are not eligible for consideration in the contest and will not be accepted.
We remind you that antennas can be hidden inside the structure or apparent integrated parts in the structure’s design, which plays a significant role in its aesthetics. In any scenario, the antennas must be located at the top. For more details, see the downloadable Material files.

The structure’s primary function is to host mobile phone antennas on its highest point, but it can also provide urban-related functionalities such as informational panels, displays with traffic information, parking availability, or other types of information, surveillance services (cameras), lighting, advertising (LED screens or banners), electric charging services (car chargers, scooters, bicycles), and so on. The constructions may also incorporate urban furniture components such as benches, bicycle racks, green areas and so on.
When selecting functionalities, evaluate the rising needs of the urban population and what unique services and functions these buildings could supply. When selecting functional pieces or devices to use, make sure that they are all readily available on the market.

The antennas must be located at the highest point of the construction, which will have an overall height of between 15 and 25 metres. You can use a pole or a portion of the main structure to get as high as possible.

Technical Information
Three sectors totaling 360 degrees of antenna emission will be housed in the structures you create. The antennas are usually mounted in a consistent pattern on a single pole above 15 metres in height, with each antenna pointing outward and spaced 120 degrees apart.
Each sector is made up of: 

- Two or more antennas positioned at the top of the structure, either level with each other or one above the other, to provide the best possible signal coverage. The hosted antennas are of the macro type for either 4G or 5G, and they can be combined into a single 4G/5G combo antenna or separated (the two options are alternatives to each other).
- Two or more radio devices placed either behind or beneath their individual antennas, or at the base of the structure (within a technical cabinet, for example).

A basic explanation of the two distinct elements is provided below:

The antennas
As previously stated, the antennas may be:

1. Combo Antennas for 4G/5G
Every antenna can be thought of as a parallelepiped with the following measurements: 2010 mm x 498 mm x 198 mm (HxLxW).

2. Antennas for 4G and 5G
Think of the antennas in this instance as two distinct antennas, one for 4G and one for 5G. The approximate measurements of the 4G antennas are 2009 × 469 × 206 mm (HxLxW), and the approximate measurements of the 5G antennas are 841 × 521 × 217 mm (HxLxW).

Radio devices
Each antenna has a radio device unit that transmits radio waves. The radio device unit can be thought of as a parallelepiped measuring 500 × 500 × 180mm (HxLxW).

In summary, each structure will have three sectors, each containing two or more antennas and two or more radio devices, resulting in a total of at least six antennas and six radio devices per structure. For installation examples, please see the downloadable Material files.

Installation and Maintenance Notes
When designing the structure, keep in mind that antennas and radio devices will require frequent maintenance. As a result, make sure both places are easily accessible and have plenty of room surrounding them.

If your design includes covering the antennas, only utilise materials that allow radio waves to propagate, such as polycarbonate, polyester nets, or fibreglass. Steel or carbon-containing materials cannot be placed in front of the antennas.
Structures are typically constructed of hot-dip galvanised steel. Use UV- and weather-resistant materials that are appropriate for outdoor locations.
Consider incorporating creative and eco-friendly aspects, sectors, or architectural elements into a structure made from the aforementioned materials (for example, bamboo, composite material coatings, and other eco-friendly materials).
Photovoltaic panels can be used as partial surface coverings to power low-consumption technological elements. However, because of their high power consumption, the radio equipment/antennas will be unable to be powered.

Submission materials
Provide detailed descriptions and up to 5 images to effectively present your projects. Images should be in 4:3 format, with .jpg, .gif or .png file formats acceptable. The colour mode should be RGB and the maximum size of a single file should be 1 MB.
To better evaluate your proposals, you are invited to upload:
- At least one render of the project in a 3/4 perspective on a white background.
- A render with urban contextualization (emphasising lighting effects, if applicable).
- At least one image including measurements, to provide an idea of the maximum dimensions, internal volumes, and structural features.
You’re also invited to use the designated field on the Upload page to attach a .zip file containing 3D files and high-resolution versions of the project images. The maximum file size for the .zip archive is 100MB.

Judging criteria
Entries will be judged based on the following criteria:

Degree of innovation 5/5
Functionality 5/5
Aesthetic quality 4/5
Technical feasibility 4/5
Economic sustainability 3/5

Desall is an international community, so all texts (abstract, description, tags, etc.) must be written in English.
