# Do I need to cover the whole building?

No, we can build a system as small as, or as large as required. Our systems are designed such that they can be modified at any time to expand or reduce coverage based on the changing needs of your building.

The smallest possible system typically comprises a rooftop antenna, repeater, and a small indoor antenna that fits directly onto the repeater. This size system is ideal for a back-office, house, demountable/donga, and covers up to about a 20-30 metre radius in these sorts of environments. Even this small-styled system can be extended by simply removing the antenna and replacing with a set of distributed antennas, ideal for scenarios where coverage needs to be expanded to nearby demountable offices, or extended from a back-office area to front-of-house. These sorts of systems can be grown to cover even two or three level buildings.

For medium-to-large sized buildings and for maximum flexibility we recommend a UBC system. These are the more modern systems that use a centralised Access Unit which connects to multiple Coverage Nodes placed strategically throughout the building. When you need to expand, we either add more antennas to a Coverage Node, or for big upgrades we add more Nodes.

It is very common for a client to improve coverage across one or two floors (priority areas), and then ask to expand to a few more floors in a following budget period.
