WinProp Release 12

Propagation

Indoor Propagation Engine

• Significant acceleration of computation due to new algorithms for the evaluation of a ray between two arbitray points (acceleration factor depends on number of objects in the database. The more objects, the higher the factor. For databases with more then 500 objects the acceleration factors are in the range of 5...8..10). 

• New prediction model: 2D Vertical Plane Ray Tracing (considering only objects in the vertical plane between Tx and Rx).

• Dominant Path Model  DPM 3.0 is now available (accelerated, more accurate, higher flexibility).
  
• Propagation paths for arbitrary prediction planes and prediction points can now be displayed in the 2D result view.
• New prediction mode: Multiple point predictions (instead of areas). Points can be located on arbitrary (individual) heights.
  

• 64 bit version of Indoor API available

• The indoor API allows now the definition of antenna patterns for the mobile stations (incl. tilt and azymuth) and to use different antenna patterns for horizontal and vertical polarization (for base station and mobile station).
  

Urban Propagation Engine

• Prediction areas can now be larger than the topographical databases. Pixels outside the topographical database are not predicted. 

• IRT (Intellig. Ray Tracing): Parallel preprocessing on multiple cores accelerates the preprocessing time significantly. 

• IRT (Intellig. Ray Tracing): The number of visibility relations for a single object was extended from 65k (16 Bit) to 2G (32 Bit). This allows in the 64 bit mode a very high resolution even for very tall buildings/towers (with visibility relations to nearly all tiles and segments in the database).
  

• DPM (Dominant Path Model) is now available in Version 3.0 (accelerated, more accurate, higher flexibility)

• Further empirical indoor coverage model with user-defined attenuation factor inside the buildings (loss per meter).
  

• 64 bit version of the Urban API available

Combined Urban <> Indoor Propagation Engine

• Propagation paths for points inside CNP buildings, etc. can now be displayed in the 2D result view.
  

• Prediction on multiple floors inside buildings. In each building the predictions relative to the floors of this building.

• Topography also included in CNP with IRT (Intellig. Ray Tracing).
  

Rural Propagation Engine

• New prediction model: Rural Ray Tracing

• Dominant Path Model is improved with respect to computation time and accuracy.
  

• Prediction areas can now be larger than the topographical databases. Pixel outside the topographical database are not predicted. 

• 64 bit version of the Rural API available

Tunnel Propagation

• Now "topography" inside the tunnel is possible (i.e. tunnel is not constant in z-coordinate).
• Radiating cables can be exported via TuMan (location of cable defined in the crosss sections) and the coordinates of the cable can then be imported into ProMan.
  

Satellite Transmitters

• Improved propagation models for satellite transmitters.

• In the projects individual path loss exponents for satellites and terrestrial antennas are now possible.

Network Planning

All Air Interfaces

• Throughput (for multiple users at the same location) and Max Data Rate (for a single user at the location of the pixel) are now written into two separate result files for easier interpretation of the results. 

• The max. number of mobile stations using the same transmission mode is now additionally predicted for each pixel in the preditcion area.
  
• The properties for TDD operation are now more flexible to adapt the settings to all air interfaces with TDD options (e.g. LTE TDD or TD-SCDMA). Now the number of frames, the guard periods, the switching blocks, etc. can be defined individually.
  

• Uplink reception probability (based on Rayleigh fading) now also available (former versions predicted this result only for the downlink).

• Transmission Modes can now be either "bidirectional", "only downlink" or "only uplink". This allows an independent analysis of the performance of the radio link in uplink and downlink.
  

• Simulation of each carrier individually possible (all other carriers are ignored for the simulation of the selected carrier). The results for each carrier are shown individually in the tree view of the result browser. 
• Four modes for cell asssignment to obtain more flexibility: Either highest power or highest SNIR can be selected as criterion. And either all carriers in the network (incl. carriers with insufficient SNIR or signal levels) or only the sucessfully received carriers can be analyzed.
  

All Air Interfaces in CNP Scenarios

• Graphical display of cell assignment with links to the serving cells (and received cells) now also available for the pixel inside buildings. 

• MIMO streams displayed graphically also for pixels inside CNP buildings.
  
• Neighbor cell list includes now additionally the evaluation of the pixels inside the buildings (and not only the outdoor pixels).
  

All Air Interfaces in Indoor Scenarios

• Graphical display of cell assignment with links to the serving cells (and received cells) now also available for the pixel inside buildings.
  

• In DAS (Distributed Antenna Systems) now the best carrier map includes the display of the signal ID (i.e. the whole coverage area of a combined cell gets the same ID).

• Neighbor cell list includes now additionally the evaluation of the prediction planes (and not only the horizontal prediction grids).
  

OFDM (LTE, WiMAX, WLAN)

• Distribution of subcarriers can be defined for different types of symbols (time-domain) to improve the accuracy in LTE downlink analysis.
  

• Prediction of RSRP, RSRQ, and RSSI for LTE networks improved.
  

• Power backoff for control channels can be defined (additionally to the power backoff for the signals used for cell assignment (reference signals)). 

• The cell load can now either influence the Tx power in downlink or the number of subcarriers used for data transmission to model the interference in LTE more accurately (especially for the interference at the border of the cells).
  

CDMA (UMTS, CDMA2000, TD-SCDMA)

• Prediction of Ec and Ec/(N0+I0) additionally to the prediction of Eb and Eb/N0.

• Code-Combining (e.g. for HSPA) now supported.

• Definition of soft/softer handover window to define the cells which are selected/considered for soft/softer handover.
  
• Own cell interference includes now the parallel streams of multiple users at the same pixel.
• Limitation of Node B with respect to the max. number of codes to be processed simultaneously is considered.
  

MIMO

• Interference between MIMO streams can be defined by the user depending on polarizations, LOS-state, etc.
  

Tools

ProMan

• Faster drawing of the 2D screen with new scrolling concept (scroll bars).
  

• New zoom features with possibility to save the settings for different zoom areas ("snapshots") in the project properties to get the same zoom areas again in a later stage.

• Export of results to bitmaps with the option to define scale, resolution, etc.. Separate export of legend possible.
• Improved (and accelerated) drawing of background bitmaps (with transparency, etc.).
  

• New tables for sites and transmitters in dialogues with multiple columns for a better overview.
  

• New icons in tree view of result browser for easier navigation and user can select if the results are opened in the current view or if a new window is opened for each result.
  

• Propagation paths for arbitrary prediction planes, prediction points, points inside CNP buildings, etc. can now be displayed. 

• Coordinates of leaky feeder cables can be imported/exported.
  

WallMan

• It is now possible to define, generate, draw, and edit clutter maps for indoor and urban vector databases (these maps can later be used for traffic modeling in the nework planning).
  

• New converter for topo & clutter pixel databases to 3D vector data format.
  

• Trajectories can be imported/exported to model time-variant objects or leaky feeder cables easier.
  
• New mode to define the movement of time-variant objects (e.g. with trajectories).
• Corners of objects can be "catched" while drawing new objects for easier generation of databases.
• Rotation of objects and total databases (especially important for import of indoor databases into urban databases in CNP mode)
  

Propagation Plug-Ins (Enterprise & Atoll)

• Indoor vector extension allows deterministic indoor predictions considering the interior walls of buildings for all transmitters of the network.

• Transmitter inside buildings are now possible. For these transmitters the walls inside the building are considered and the full outdoor prediction area is predicted.

• The user can also work with single buildings (indoor data format) and then the RNP (Enterprise, Atoll,...) can be used as an indoor planning tool with the indoor propagation engine of WinProp computing the propagation on different floors and with the network planning engine of the RNP computing the network anaylsis for each floor individually.
