Term
Definition
MAC
Medium Access Controller - responsible for several functions such Error
Correction, Packet (De)Multiplexing, etc.
MBSFN
Multicast-Broadcast Single Frequency Network is an LTE feature
designed to deliver services such as Mobile TV using the LTE
infrastructure, and is expected to be a competitor to DVB-H-based TV
broadcast
MCS
