This is how the evolution is going: 
 
 2G introduced digital voice calls and SMS, improving call quality and enabling text messaging.
 
 3G brought higher data speeds, video calls, and global roaming.
 
 4G LTE offered broadband-like speeds, VoLTE for better voice quality, and seamless streaming of HD videos and online gaming.
 
 5G revolutionizes wireless technology with ultra-fast speeds, low latency, massive IoT connectivity, and network slicing for tailored performance.
 
 How does it affect antenna design:  Antennas have adapted with beamforming, MIMO, and small cells to meet the demands of each new generation.
