The procurement concerns an Anechoic RF Chamer (hereinafter referred to as "Chamber") for wireless communication technology, to be integrated into the WICO research environment and primarily used by the Tampere Wireless Research Center. The facility will be used for conducting Over-The-Air (OTA) antenna measurements, supporting advanced research and experimental validation in wireless communications. The chamber will enable research on current and future wireless systems and will further strengthen the existing high-level research in the field. The object of the tender process is described in more detail in the invitation to tender documents. A dedicated space has been allocated for both the chamber and an adjacent control room. Detailed layouts and spatial specifications are provided in the appendices to this tender. In addition, a separate appendix outlines the existing measurement equipment that will be installed and utilized within the new chamber. The chamber will be constructed within the Sähkötalo building, in the F-wing. The chamber is effectively located at the ground-floor level, allowing convenient access through large doors. This facilitates the transportation and installation of sizeable chamber components and measurement equipment. The selected supplier will be required to conduct a site survey promptly after contract signing. The purpose of the survey is to verify all relevant dimensions, environmental conditions, and technical details necessary for the design and installation of the chamber. Access to the site during the renovation phase will require coordination with the main construction contractor (details are provided after the contract has been signed). It is expected that participation in a mandatory construction site safety training (approximately one hour) will be required prior to site access. At the time of issuing this tender, the specified area within Sähkötalo is undergoing renovation. The renovation is scheduled for completion by the end of April 2027. Consequently, construction of the anechoic chamber is expected to commence at the beginning May 2027, subject to the completion of renovation works and in the absence of unforeseen delays. The anticipated construction period for the chamber is during spring-summer 2027. Budget Available: Please note maximum budget available for this procurement is no greater than 500.000 € (EUR, excl.
