"My focus is on developing a converged communication network architecture that enables seamless mobile access to voice, data and multimedia services for cellular users, police officers and enterprise workers."

Creating systems enabling seamless mobility for public safety
As a Motorola Fellow and a Dan Noble Fellow, Mario DeRango has strived to provide global public safety agencies with the most advanced communication networks available to support their mission critical needs. Since joining Motorola, he has served as a lead architect within Motorola's government business on several major system initiatives, including in the early 1990s the first Land Mobile Radio system architecture incorporating a fully digital two-way radio technology. This later became the basis for the P25 Public Safety communications standard.

In the late 1990s, Mario was the lead architect for the transition of government wireless networks to packet based infrastructures, including the architecture design for the first Internet Protocol-based core network for worldwide P25 and TETRA systems. This architecture pioneered IP Multicast innovations to support mission critical voice over IP for both group and individual dispatch (push-to-talk) call services. He was also lead architect for Motorola's government broadband technology strategy, and helped influence the Federal Communications Commission (FCC) to open up the 4.9GHz band for public safety solutions, including advanced wireless backhaul, Wi-Fi and mesh networking architectures.

Mario leads the Common Architecture and Systems Engineering team within the Advanced Technology, Standards and Common Engineering organization of the Networks and Enterprise business, the scope of which includes all cellular and enterprise network architectures in addition to government.

Driving convergence across all wireless markets
Motorola is uniquely positioned to serve multiple markets for wireless systems. Historically these systems required substantially different architectures and wireless protocols. However, as the architectures for wireless communication networks begin to converge on a common set of wireless and Internet based protocols and services, system components and entire solutions can be deployed equally well across cellular, government and public safety, and enterprise communication networks. Mario and his team of system architects and software engineers are responsible for achieving this convergence for Motorola's solutions.

What does Mario's work at Motorola mean?
It means Motorola can develop world-class networks based on system architectures that enable the realization of the seamless mobility vision. These common architectures and platform based development allow Motorola to operate more efficiently, while also enabling new innovative services that can interoperate seamlessly across a combination of networks. The result is Motorola's customers are safer and more productive as they remain connected to one another and to their critical information sources. As an example, it means improved Homeland Security Interoperability as public safety users will have the ability to use any network, whether public, enterprise or government operated, to securely communicate and access information.
