The Colombian integrator grew by following its customers across borders. Now it is selling a harder promise: making the networks, security systems and people behind critical infrastructure work together.
New Zealand’s third mobile network won attention with 44-cent calls. Its next act involves fibre, private 5G and a proposal to share infrastructure with an old rival.
Under railway tracks, around racetracks and inside livestock sheds, Boldyn builds networks that other businesses use. Its wager: sharing the infrastructure can make difficult connections worth the expense.
SISL Global built a $220 million business around a stubborn corporate nuisance: keeping hardware, networks and people working across borders without turning every country into a separate project.
The Fort Mill company is stitching cameras, sensors and wireless links into one operating layer for remote sites - a useful idea whose economics depend less on magical AI than on good placement, clean signals and humans who still make the call.
Boingo began by making airport Wi-Fi easier to buy. Twenty-five years later, its real product is the invisible layer beneath airports, bases and ballparks - a lesson in moving from a convenient app to infrastructure that is painful to replace.

He left a vast telecom organization for a startup with two scientists and a difficult idea: let radios share. A decade later, Iyad Tarazi is applying the same instinct to AI, physics and the stubborn economics of wireless networks.
For 16 years, a nine-person Raleigh company has argued that the most underused computer in telecom is already inside the device. SIMbae turns that overlooked chip into a programmable traffic cop for connected fleets - with no new hardware and far less Java Card work.
For a decade, Federated Wireless made crowded radio bands behave like orderly airspace. Its next wager is that physics-aware AI can turn the same towers and frequencies into much more network.
Rakuten built a mobile network in Japan, then turned the operating lessons into software for everyone else. The wager is that telecom's next upgrade looks less like a hardware swap and more like a cloud migration.
The 149-year-old Swedish firm that helped write the rules of 5G now has to prove those networks can grow again - under a new CEO and an AI-driven cost squeeze.
