Bit-oriented transmission reduces system-related latency compared to packet-based communication
reduces susceptibility to external electromagnetic interference and facilitates coexistence with existing wireless systems such as WLAN or Bluetooth. In many industrial scenarios, this can significantly reduce the effort required for frequency and coexistence planning. Multiple NearFi connections can operate in parallel in close proximity without interfering with one another, which supports scalable architectures. applications where connectors or slip rings require frequent maintenance. Industrial-grade housing designs and standardized connection designs support use in harsh environments.
System security through physically limited coupling The highly spatially limited coupling reduces the range of potential eavesdropping and attack attempts. Since NearFi operates at the physical layer and does not provide its own network identities or management mechanisms, cybersecurity-related functions are primarily shifted to the connected end devices and their application and protocol layers. This can simplify the risk analysis, but it does not replace a system-wide safety assessment.
Robustness against offset, rotation, and motion NearFi reduces the requirements for mechanical precision, as offset and angular deviations are tolerated within the specification. As a result, NearFi couplers are well-suited for moving and rotating
