Linkkapazität

Linkkapazität refers to the maximum amount of data that can be transmitted over a communication link within a given time period. It is a fundamental concept in telecommunications and computer networking, determining the performance and efficiency of data transfer. Often measured in bits per second (bps), kilobits per second (kbps), megabits per second (Mbps), or gigabits per second (Gbps), link capacity is influenced by various factors.

These factors include the bandwidth of the communication medium, the signal-to-noise ratio (SNR), the modulation scheme used, and the encoding techniques employed. For instance, a wider bandwidth generally allows for higher data rates. Similarly, a higher SNR, indicating a stronger signal relative to background noise, permits more complex modulation schemes that can encode more bits per symbol, thus increasing capacity.

The theoretical maximum capacity of a communication channel is described by the Shannon-Hartley theorem, which relates capacity to bandwidth and SNR. In practice, actual achievable link capacity is often lower than the theoretical maximum due to overhead from protocols, error correction mechanisms, and other processing delays. Understanding and managing link capacity is crucial for designing effective networks, ensuring smooth data flow, and meeting the demands of modern applications that require high-speed data transmission.
