📡 FDD (Frequency Division Duplex) uses separate frequencies for uplink and downlink, making it ideal for voice calls, wide-area coverage, and low-latency communication.

⚡ TDD (Time Division Duplex) shares the same frequency by alternating between uplink and downlink in time slots, making it highly efficient for high-speed data and dense urban deployments.

Modern 4G and 5G networks often combine both technologies to achieve the perfect balance:
✅ Reliable voice services
✅ Excellent coverage
✅ Higher network capacity
✅ Faster data speeds
✅ Better user experience

Understanding the strengths of FDD and TDD helps engineers design smarter, more efficient wireless networks for our connected world.

📡 How Are -

Ever wondered how modern base station antennas achieve high gain, improved coverage, and efficient dual-band operation without becoming bulky?
One powerful solution is the Frequency Selective Surface (FSS). By selectively reflecting specific frequency bands while allowing others to pass, FSS structures help enhance antenna performance, improve isolation, and maintain a compact low-profile design.
In this poster, we explore a dual-band base station antenna operating in the 0.69–0.96 GHz low band and utilizing an FSS reflector for the 3.3–3.8 GHz high band. The results demonstrate excellent impedance matching, strong radiation performance, and significant gain enhancement key requirements for modern wireless communication systems.
