LTE user plane simulation model, compatible with the INET Framework.

Features

General

eNodeB and UE models
Form-based configuration editor

PDCP-RRC

UM, (AM and TM testing) modes

MAC

RLC PDUs buffering
HARQ functionalities (with multi-codeword support)
Allocation management
AMC
Scheduling Policies (MAX C/I, Proportional Fair, DRR)

PHY

Heterogeneous Net (HetNets) support: Macro, micro, pico eNbs
Channel Feedback management
Dummy channel model
Realistic channel model with
- cell interference
- path-loss

- shadowing
- (an-isotropic antennas - work in progress)

Other

X2 communication support
(Relay support - work in progress)
Distributed Antenna System - DAS (Testing)

Applications

VoIP
Gaming
Trace Based traffic

Limitations

User Plane only (Control Plane not modeled)
FDD only (TDD not supported)
no EPS bearer support – note: a similar concept, "connections", has been implemented, but they are neither dynamic nor statically configurable via some config file
radio bearers not implemented, not even statically configured radio bearers (dynamically allocating bearers would need the RRC protocol, which is Control Plane so not implemented)
handovers not implemented (no X2-based handover, that is; S1-based handover would require an S-GW model)

Using the configuration editor

SimuLTE also contains a form-based configuration editor to edit the most often used simulation parameters. To use it, right-click an Ini file, and choose 'Open With | SimuLTE Configuration Editor' from the context menu. Try it on 'simulations/demo/gui.ini'.
