Highlights
- phone seamlessly bounced from one tower to another, without you noticing.
- hard” handoff is when connection with one tower must break before making with a new one.
- soft” handover is when the new connection is made, there is a bit of overlap, and then the old one is dropped.
- Phone <> cell tower, 2 parallell calls basically start at that point, while the telephone operator still sends data from source call to the other end.
- Then while both connections are strong, the telcom operator switches which incoming data stream it is connecting to the other end.
- And once that is working for a few milliseconds/seconds at good health, it drops off the older line.
