As mobile networks evolve toward 5G and beyond, the ability to securely manage who connects, what they can do, and how those actions are tracked isn’t just a feature — it’s the foundation. This is where AAA (Authentication, Authorization, and Accounting) becomes indispensable.
Historically, satellite communication was reserved for the “unreachable” — distant islands, deserts, or mountain ranges. But that paradigm is rapidly dissolving. Thanks to the rise of Low Earth Orbit (LEO) constellations and falling launch costs, satellites are now being considered a viable — and increasingly essential — part of mobile and broadband networks.
Recently, South Korea’s largest mobile network provider experienced a nationwide service disruption that left over 13 million users without voice and data connectivity for several hours.
The evolution of mobile networks has always been about more than just faster speeds. Each generation—from 1G to 5G—has transformed the way we live and communicate.
In a decisive move to protect the nation’s communications infrastructure, the United States has expanded its efforts to eliminate untrusted telecommunications equipment through the Federal Communications Commission (FCC)’s “Rip and Replace” program—officially known as the Secure and Trusted Communications Networks Reimbursement Program.
In today’s telecom landscape, user expectations are higher than ever. Real-time connectivity, seamless experiences across services, and smart data usage policies are no longer a luxury — they are a necessity. This is where Policy and Charging Rules Function (PCRF) and Policy Control Function (PCF) step in, playing a critical role in network intelligence and flexibility.
