RNC
RNC (Radio Network Controller) is an important piece of equipment in mobile phone networks. It's like a traffic controller that manages multiple cell towers and helps coordinate how mobile phones connect to the network. When someone talks about RNC in their resume, they're usually referring to experience with managing or working with these systems in mobile network operations. Think of it as the middle manager between cell towers and the core network - it makes sure calls don't drop when people move between different cell towers and helps manage network resources efficiently.
Examples in Resumes
Managed RNC operations for a network of 200 cell sites
Optimized Radio Network Controller performance resulting in 30% fewer dropped calls
Configured and maintained RNC systems for 4G/5G network deployment
