Korträckvidd

Korträckvidd, meaning "short range" in Swedish, is a term often encountered in various contexts, particularly within technology and communication. It generally refers to a limited distance over which a signal or interaction can effectively occur.

In wireless communication, korträckvidd technologies typically operate within a few meters. Examples include Bluetooth, which is commonly used for connecting devices like headphones, speakers, and keyboards to smartphones or computers over short distances. Near Field Communication (NFC) is another prominent korträckvidd technology, enabling contactless payments and data transfer when two devices are brought very close together, usually within centimeters.

The concept of korträckvidd is also relevant in fields such as acoustics, where sound intensity diminishes rapidly with distance, or in optics, for lasers with limited beam penetration. The advantages of korträckvidd systems often include lower power consumption, reduced interference with other devices, and enhanced security due to the proximity requirement. Conversely, their primary limitation is the restricted operational area. Understanding the meaning and application of korträckvidd is key to appreciating the design and functionality of many modern electronic devices and systems.
