Coverage Economics Moved Spending From Concrete To Sensors
A mile of physical barrier costs around USD 21 million and secures exactly one mile, while an autonomous tower costs a fraction of that and detects across a radius near 7.5 miles. That comparison settled the argument in most programmes without much debate, and barrier construction slowed as tower deployment accelerated. The shift favours sensor and integration suppliers over civil works contractors, and it has reshaped which firms hold significant border programme revenue. Civil works contractors who held large positions a decade ago now bid into programmes that barely mention concrete.
Market Impact: Costs USD 21 million per mile
