The Building Blocks of 5G Latency

When the 3GPP announced the beginning of 5G development back in 2015, the group proposed many performance objectives pertaining to all aspects of the network. Eventually the 3GPP distilled the various metrics down to three distinct use cases: enhanced mobile broad band (eMBB), Ultra Reliable Low Latency Communications (URLLC), and Massive Machine Type Communications (mMTC). There has been much written and published on the eMBB use case and even the mMTC to a lesser extent with the anticipation of smarter devices and pervasive IoT. Although the URLLC use case has garnered less attention, it may in fact prove more impactful than either of the former use cases.
