5G’s Orthogonal Frequency Division Multiplexing (OFDM) brings with it a major design challenge, namely an inherent wide dynamic variation between a signal’s peak and the average power. The peak-to-average power ratio (PAPR) leads to inefficient transmission performance. That’s because the OFDM waveform is created by the sum of multiple sinusoidal signals that can exhibit constructive…
Our second 5G Handbook is now available

OpenRAN mid-band radio brings cellular to private and campus networks
Benetel’s RAN650 operates in the n77u band, which covers CBRS and other private network frequencies. It’s compliant with O-RAN fronthaul specifications.
How DPD improves power amplifier efficiency
Digital predistortion compensates for an amplifier’s nonlinearities, letting it operate in its nonlinear region for maximum power efficiency.
Functional Splits: the foundation of an Open 5G RAN
The open standards for radio access networks offer options for locating network functions. These functional split options depend on network services and available transport links.
