The major challenge is the . High-accuracy sensing requires long pilot sequences or high-power chirps, which reduce data rate. Researchers are exploring novel waveforms (e.g., orthogonal time frequency space - OTFS) and deep learning to jointly optimize both functions.
: Moves beyond "add-on" security to a secure-by-design approach, incorporating physical-layer security (PLS) and quantum-resistant cryptography. The major challenge is the
As networks become more "aware" through sensing, the attack surface expands. The massive influx of data from billions of sensors, combined with the sensitive nature of environmental mapping, makes security a paramount concern. 6G moves beyond traditional software-based encryption toward Physical Layer Security (PLS). : Moves beyond "add-on" security to a secure-by-design
The integration of security into 6G wireless networks will enable a wide range of applications, including: This is the "multi-functional" promise.
👇 Let's discuss.
The full potential of 6G emerges only when all three functions operate cooperatively. This is the "multi-functional" promise.
