6G goals to attach the bodily, digital, and human worlds via rising expertise specializing in new spectrum utilization, synthetic intelligence integration into networks and units, digital twins, and new community architectures. These parts improve community programmability and automation throughout varied 6G use instances.
Whereas the business deployment of 6G appears fairly distant, the analysis wants for 6G are already right here, together with rising efforts across the spectrum. New frequency ranges are wanted to fulfill the bandwidth wants of the ever-growing throughput necessities. Frequency vary 3, or FR3, is among the new spectrum ranges the place 6G is evolving. There have been solely two frequency ranges for 5G: FR1 and FR2. FR3 is between FR1, also known as sub-6 GHz, and FR2, the so-called millimeter-wave vary, between 7 and 24 GHz.
6G Necessities : A Drive In direction of Deterministic Channel Fashions
4G and 5G addressed radio channel modeling necessities utilizing geometry-based stochastic channel fashions (GSCMs) for simulating and testing large multiple-input and multiple-output (mMIMO) methods. Nevertheless, 6G use instances and applied sciences are producing new necessities for radio channel modeling due to:
- Close to-field (NF) and short-range communications utilizing smaller cells.
- The necessity for correct location-based companies.
- Sensible environments with a number of radio entry applied sciences.
- Propagation challenges at sub-terahertz (THz) frequencies.
- Versatile adaptation and enhanced environmental consciousness.
- Built-in sensing and communication (ISAC) and excessive MIMO (xMIMO).
6G FR3 Radio Channel Modeling
Antenna arrays with substantial apertures are below investigation within the 6G FR3 band for MIMO applied sciences, together with MIMO, mMIMO, and xMIMO. xMIMO antenna arrays help slender pencil beams and extra MIMO layers than typical mMIMO. Determine 1 reveals an instance of maximum hybrid beamforming, FR3 higher mid-band base station. Because of this, the design and validation of xMIMO wi-fi methods necessitate correct intra- and inter-cluster angular traits from the channel mannequin.
Making certain that the channel mannequin precisely captures the intra- and inter-cluster angular traits is important when conducting system simulations or testing the precise efficiency of xMIMO base stations in RAN and Open RAN configurations. As well as, dynamic channel fashions are vital for evaluating beam administration and precoding adaptation over person gear motion. These channel fashions think about transitions between line-of-sight / non-line-of-sight and blockage situations.
Nevertheless, the present 3GPP GSCM channel fashions lack the accuracy wanted to develop excessive beamforming algorithms with extremely directive pencil beams. To deal with that, a brand new 3GPP RP-234018 Launch 19 technical examine merchandise on channel modeling enhancements for 7 to 24 GHz for New Radio (NR) was initiated.
To check the higher mid-band for FR3, take a look at engineers want:

- Semi-deterministic and/or deterministic channel fashions.
- Precisely calibrated gear for section and amplitude measurements.
- Complete measurement and evaluation instruments.
6G FR3 System Testing
6G FR3 system testing requires section and time-coherent multichannel emulation utilizing semi-deterministic and deterministic channel fashions. From the bodily layer (PHY) to the applying layer, key efficiency metrics for 6G FR3 testing embody:
- Beam weight estimation and pointing metrics.
- Beam form and achieve.
- Sidelobe ranges.
With a strong channel emulation answer, take a look at engineers can reproduce a various propagation surroundings and emulate {hardware} impairments like section noise and interference. They may want:
- Channel emulation capabilities to create life like and extremely correct 6G FR3 surroundings fashions.
- Sign technology capabilities to offer the required 6G transmit waveform to the channel emulator.
- Efficiency metrics, together with beamforming achieve, beam width, and sidelobe ranges.
- Software program instruments to carry out section and time-coherent multichannel emulation and create geometry-based stochastic channel fashions.
- Testing surroundings to breed propagation environments and guarantee complete testing.

Keysight 6G FR3 system take a look at answer features a channel emulator, channel emulation software program, and an MXG sign generator.This answer creates life like and extremely correct stochastic and deterministic fashions for mimicking 6G FR3 parts and methods. The MXG sign generator offers the sign enter to the FR3-capable channel emulator. The channel emulator additionally helps ISAC for detecting and monitoring objects.
The Backside Line
Exact channel emulation is essential for 6G FR3. Correct channel fashions are wanted to help superior 6G options and permit for life like testing of 6G applied sciences, comparable to mMIMO and beamforming, below varied situations to grasp how these applied sciences will carry out in real-world eventualities. Moreover, it helps superior use instances like ISAC, which require detailed information of the channel traits to operate successfully.
Be ready for 6G and the challenges it brings onboard and speed up your 6G prototyping earlier than releasing requirements utilizing Keysight options for channel modeling and emulation for FR3 MIMO, mMIMO, xMIMO, and ISAC.
