CDMA
CDMA (Code Division Multiple Access) is a method that allows multiple users to share satellite and wireless communication channels at the same time. Think of it like having many people speaking different languages in the same room - everyone can communicate simultaneously because they're using different 'codes'. It's commonly used in satellite phones, GPS systems, and some types of mobile networks. When you see this term in a resume, it usually indicates that the candidate has experience with satellite communications systems, mobile network technologies, or wireless communication equipment.
