NetSim v13 New Release!

The May 21 release comes with exciting new features and updates including:

  • 5G Core (Based on TS23.501, TS23.502) functions and interfaces:
    • Access Mobility Function (AMF) that coordinates the 5G Standalone registration procedure, SMF and UPF
    • Session Management Function (SMF) that serves as a control plane entity and is responsible for the session management
    • User Plane function (UPF) that is a data plane component that handles user data
    • Interfaces: N1/N2, N3, N4, N6, N11, XN
  • 5G NSA deployment architecture (in addition to existing SA mode)
    • For LTE – 5G dual connectivity, to leverage existing LTE RAN/EPC deployments.
    • Option 3 where only LTE core/ EPC is present and no 5G Core devices are present. Here, eNB is the Master Cell and gNB is the Secondary Cell.
      • Option 3: Only eNB connects to EPC and eNB and gNB connects to the XN interface.
      • Option 3a: Both eNB and gNB connects to the EPC. No XN interface.
      • Option 3x: Both eNB and gNB connects to the EPC. eNB and gNB connects to the XN interface.
    • Option 4 where only 5G Core devices are present, and EPC is not available. Here, gNB is the Master Cell and eNB is the Secondary Cell.
      • Option 4: Only gNB connects to all the 5G Core interfaces. eNB connects to the XN interface.
      • Option 4a: gNB connects to all 5G Core interfaces and eNB connects to AMF and UPF through respective interfaces.
    • Option 7 where only 5G Core devices are present, and EPC is not available. Here, eNB is the Master Cell and gNB is the Secondary Cell.
      • Option 7: eNB connects to all 5G Core interfaces. gNB connects only to the XN interface.
      • Option 7a: gNB connects to all the 5G Core interfaces. eNB connects to AMF and UPF through the respective interfaces.
      • Option 7x: gNB and eNB connects to all the 5G Core interfaces.
  • 5G RAN
    • FDD bands added to existing TDD bands
    • MIMO operation with layer count equal to Min (Tx-antenna-count, Rx-Antenna-count). Note that NetSim v12.2 used the abstraction “layer count” directly as a user input
      • gNB antenna count supported 1, 2, 4, 8, 16, 32, 64, 128
      • UE antenna count supported 1, 2, 4, 8, 16
    • MIMO Spatial channel model
      • MIMO Spatial Channel Model (SCM), i.e., the channel is represented by a matrix H, whose entry (t, r) models the channel between the t-th and the r-th antenna elements at the transmitter and the receiver, respectively
      • Gaussian channel with Rayleigh fast fading: i.i.d Complex Normal (0, 1) channel (H-matrix) that changes independently every coherence time.
      • Beamforming gain per the eigen values of the covariance (Wishart) matrix
    • Ability to input per gNB pathloss files from 3rd party software tools like MATLAB
      • Pathloss along cartesian X, Y coordinates in a mesh grid around the gNB
      • Best server (gNB) per UE calculation automatically handled by NetSim
  • Military Radios (TDMA Radio Networks)
    • Forward error correction (FEC)
    • L-band and S-Band Radios
  • Device models
    • Processing delay to simulate compute related latencies
  • Applications
    • Faster FTP fragmentation for simulation acceleration
  • Satellite
    • Updates to Markov Loo fading model in Satellite networks
  • Graphics
    • Simple and Smooth working
    • Reimagined home screen design
    • Workspace enhancements: Size field for experiments and workspaces, and File selection option for import/export
  • Documentation
    • Figure and table numbers for all manuals with cross referencing
    • New examples and experiments (for Edu users)
  • Utilities
    • Config file generator: Automated scenario generator for generating large scale networks with 1000s of nodes.
    • Batch simulations: Automated execution of 100s of config files sequentially. Ideal for running simulations over night
    • Multi-parameter sweeper: Automated sweep of multiple parameters across its range of values and logging of results in csv for analysis
