ASSET enables to plan a DVB-H network [DVB-H (Digital Video Broadcasting - Handhelds), part of the DVB-T (Terrestrial) standard, is a broadcast technology] as follow .
Set up a Standard Long-Range propagation model
Use the UMTS functionality to represent a DVB-H network
Run a simulation to generate a C/I array
using the following propagation model
Model
Brief Description
Recommended Usage
Mapping Data Needed
Standard Macrocell 3 (mk:@MSITStore:C:%5CProgram%20Files%5CAIRCOM%20International%5CENTERPRISE%206.2%5CHelp%5CASSET.chm::/11570.htm)
General Purpose macrocell model that accounts for the different elements of propagation in the wireless channel.
Can be typically calibrated to less than 7dB standard deviation.
Models 1 and 2 are only supported for customers who still want to use them, and upgrade from previous versions of ENTERPRISE (these models cannot be added).
Sites in environments where the distance from the site is greater than approximately 500m
Base station antenna heights in the range of 15-200m
Receiver heights in the range of 1-10m
Terrain DTM height - raster data
Terrain clutter - raster data
Clutter and Height data should be of the same resolution(s). Although there is no minimum resolution, recommended pixel sizes for this data are between 20m and 200m.
Enhanced Macrocell (mk:@MSITStore:C:%5CProgram%20Files%5CAIRCOM%20International%5CENTERPRISE%206.2%5CHelp%5CASSET.chm::/48029.htm)
In the pathloss calculation parameters for this model, you can specify the slope and intercept parameters (k1 and k2) independently for LOS and NLOS. These parameters are used dynamically during the propagation calculations.
It is advantageous to use this model in environments with hilly terrain
It has several further advantages over the Standard Models, as described in About the Enhanced Macrocell Model (mk:@MSITStore:C:%5CProgram%20Files%5CAIRCOM%20International%5CENTERPRISE%206.2%5CHelp%5CASSET.chm::/48029.htm).
As above.
MYRIAD model
The MYRIAD model is the successful result of several years of research in such domains as propagation, modelling, optimisation and algorithms.
The MYRIAD model is able to automatically adapt itself to all engineering domains, radio environments and systems.
The model relies on highly realistic modelling of the propagation channel.
All cell sizes (micro, mini, small, and macro cells)
All radio environments (dense urban, urban, suburban, mountainous, maritime, open)
All systems (DVB-H, GSM, GPRS, EDGE, UMTS, CDMA2000, EV-DO, WiFi, WiMAX)
Frequencies from 400MHz to 5GHz
As above.
For full information on how to use this model, refer to the MYRIAD Help or MYRIAD User Reference Guide.
SUI model (mk:@MSITStore:C:%5CProgram%20Files%5CAIRCOM%20International%5CENTERPRISE%206.2%5CHelp%5CASSET.chm::/33903.htm)
The SUI (Stanford University Interim) model is one of the recommended models for use in analysing fixed wireless broadband communication networks such as Fixed WiMAX (802.16d standard) at frequencies below 11GHz.
Cells with radius <10km
Can be used for various terrain and tree density types
Base station antenna heights in the range of 15-40m
Directional antennas (2-10m) at the CPE receiver, installed on or below rooftops or windows
Terrain DTM height - raster data
Terrain clutter - raster data
Clutter and Height data should be of the same resolution(s). Although there is no minimum resolution, recommended pixel sizes for this data are between 20m and 200m.
SLR model (mk:@MSITStore:C:%5CProgram%20Files%5CAIRCOM%20International%5CENTERPRISE%206.2%5CHelp%5CASSET.chm::/35773.htm)
The SLR model in ASSET is partly based on the ITU-R P1546-2 recommendation. The model can be used for DVB-H planning or for other applications that require long-range calculations (1-1000km).
Point-to-Area model that can be used to make predictions for terrestrial services in the frequency range of 100 to 2000 MHz.
Restricted to 50% time variability and to a land path.
Terrain DTM height - raster data
Terrain clutter - raster data
Clutter and Height data should be of the same resolution
as final i have aseet 6.2 full version ,i need support to have a newer license for it
