Understanding next-generation wireless frequencies, AI applications, and intelligent surfaces
Source: IEEE Spectrum6G wireless networks are being shaped by ten major technological components. Key enablers include THz (terahertz) communications above 100 GHz, the 7 24 GHz frequency range, AI/ML-based signal processing, reconfigurable intelligent surfaces (RIS), and photonics. THz bands face CMOS technology challenges at sub-THz frequencies, which new semiconductor approaches aim to solve. AI/ML will replace traditional signal-processing blocks through auto encoder-based learning. Joint communications and sensing will allow single waveforms to serve both data transmission and radar functions. Reconfigurable
