The Stella Repeater System is a simple, most cost effective way to enable mobile signal within the office. The external antenna receives the signal from the operators from outside, and amplifies and distributes the signal throughout the building in all desired areas. The Stella Online Planning Tool is available to installers to help plan the layout. Building plans can be uploaded and antennas and cables can be positioned on the plan to indicate the locations that will provide the best coverage. As a rough guide, 1 antenna is installed every 20m in the corridors of the building and the signal passes into the adjacent rooms. This saves time on site ensuring minimal disruption to the workplace.
