Samsung Galaxy Z Fold 4

• 5G Dual-SIM Architecture: Houses a comprehensive 5G layout running on the Snapdragon X65 5G modem. It supports physical Nano-SIM alongside eSIM integration with full Standalone (SA) and Non-Standalone (NSA) carrier compatibility.
• Wi-Fi 6E (Tri-Band): Utilizes the less crowded 6GHz spectrum alongside legacy 2.4GHz and 5GHz airwaves. It is enhanced with HE160 (160MHz channel bandwidth), MIMO, and 1024-QAM modulation for smooth intra-network media streaming or local NAS data synchronization. 
• Bluetooth 5.2: Delivers high-speed audio and peripheral connections. It enables concurrent multi-device routing to cross-pair keyboards, tracking mice, and high-fidelity wireless earbuds simultaneously without introducing perceptible input lag. 
• Advanced Hardware & I/O Technologies
  The engineering of the physical framework handles massive multimedia feeds and physical workspace mirroring:

USB Type-C 3.2 Gen 1: The primary structural data port guarantees hardwired line transmission speeds up to 5 Gbps. It natively supports DisplayPort Alternate Mode, pushing clean uncompressed monitor feeds through standard USB-C dongles.

Ultra-Wideband (UWB): Features an integrated UWB antenna array for precision micro-spatial tracking. It allows you to track spatial location trackers with centimeter-level precision or automatically unlock compatible smart vehicles and smart home locks. 

Samsung DeX (Desktop Experience): Fully transforms the smartphone interface. It projects an adapted desktop environment onto external physical screens—either over a hardwired USB-C setup or wirelessly over a Wi-Fi 6E local area loop.
