An Infrastructure Hub is the cornerstone of any empire´s expansion into nullsec territory.
Once online, it allows the owner to cultivate the system it is placed in by applying one of the upgrades available. These upgrades range from simple improvements to a system´s financial infrastructure, to defensive upgrades giving the system owner significant advantages.
As an added bonus, the Infrastructure Hub functions as a defensive structure as well, as sovereignty cannot be taken while it is still online.
