Exciting times, was prepping for this while applying to Ericsson.

5G is not just about increasing the Bandwidth compared to 4G - it “represents a fundamental rearchitecting of the access network in a way that leverages several key technology trends and sets it on a path to enable much greater innovation”.

In the same way that 3G defined the transition from voice to broadband, 5G’s promise is primarily about the transition from a single access service (broadband connectivity) to a richer collection of edge services and devices.

For more of the vision, see Qualcomm note.


In many ways, I think learning about 5G is the same as when we first learned about the Internet, or the Metaverse (or Crypto / Web3?). It was pretty hard to comprehend what it is.

5G is standardized by the 3rd Generation Partnership Project.


Use Cases:

  1. enhanced Mobile Broadband (eMBB)
  2. massive Machine Type Communications (mMTC)
  3. Ultra-Reliable and Low Latency Communications (URLLC)

5G Waveforms
