Relay Network

Relay networks are designed to enhance wireless communication by using intermediate nodes—called relays—to forward data between the source and destination. This structure significantly improves coverage, especially in areas with physical obstructions or weak signals, by extending the transmission range beyond direct communication limits. Relay networks also boost capacity by enabling multiple simultaneous transmissions, which increases throughput and reduces latency. Their architecture supports redundancy, making them more reliable and resilient to failures. Additionally, they are well-suited for modern applications like 5G, where high-speed, low-latency communication is essential. Despite challenges such as interference, complexity, and security concerns, relay networks employ advanced techniques like beamforming, encryption, and routing optimization to maintain performance and integrity
