The project Space of Signal in a speculative design that explores the potential impact of 5G signal on built environment. As proved by the conducted research, the Presence of 5G Transmitter will encourage the act of gathering of e-businesses in the close proximity to signal source, as this will remain the guaranty of reliable and stable 5G connection. Therefore, the scope of the project may be defined as 5G implementation model consisting of signal transmitter and receiver design, where the primary spatial topic will be the relation between two buildings. Both facilities are considered with a particular focus towards the urban relation between facilities, efficient placement of antennas and spatial consequences within each building. The project will therefore embrace the different spatial qualities required by signal transmitter and receiver. By looking through the scientific lenses of signal streams and directions, the final outcome depicts, how the built environment that surround us continuous to be shaped by individual dimension of signal.
