: Unraveling the Differences between Dual Connectivity and EN-DC for Enhanced Mobile Network Performance"
Dual Connectivity (DC) :
- Simultaneous connection to two different base stations
- Can involve same or different radio access technologies (RATs)
- Improved coverage
, higher data rates 
, and seamless handovers
- Applicable to various combinations of 4G and 5G networks
E-UTRAN New Radio - Dual Connectivity (EN-DC) :
- Specific implementation of Dual Connectivity
- Simultaneous connection to both LTE (4G) and 5G base stations
- Smooth transition from 4G to 5G networks
- Enhanced network performance with better coverage and higher data rates
- Seamless user experience during the transition
Examples 
:
DC:
Video streaming 
on a smartphone while moving between different network cells, ensuring smooth and uninterrupted playback 
with connections to two base stations
EN-DC:
Downloading a large file 
on a smartphone in an area with both 4G and 5G networks, combining resources for faster download speeds and better coverage through connections to both 4G and 5G base stations
Key Takeaways 
:
- Dual Connectivity (DC) is a broader concept , applicable to various RAT combinations
- EN-DC is a specific implementation of DC , focusing on the connection between 4G and 5G networks
- Both techniques aim to improve network performance, coverage, and data rates for users
