It considers terrain heights (elevation) on the path and building data, transmitter and receiver heights. It is combined with the distance and angle measurement tool. Start and end business points may snap to the nearest object (e.g. A site antenna or a client, or point taking the configuration of the start and end objects where it snaps to into account. These start and end objects are also directly considered in the link budget calculation which makes planning of dedicated links fast and easy. Point coverage by point field strength calculation the exact field strength and power level for each point on the map is calculated. The points tab in the Project-Explorer shows all points used in the current project. This table can easily be exported and used for further analysis steps. To discover the total power received on a point for a channel the power channel sum can be calculated.
Within its 2d-view and partly also within its 3d-view wimap-4G is able to visualize several different topics, which are based on a previous calculated field strength prediction. The following results are available in wimap-4G with individual defined renderers: coverage based on C/I and power receiving levels Best Server Carrier to Interferer Power level Sub-Carrier Interference field strength Site-to-site link-budget The site-to-site prediction is a special case of the link-budget calculation. For any initial antenna (might be many) the power level to any other antenna of the same carrier and within a suitable range is calculated and visualised as a coloured line, and are shown as tool tips. This is in particular helpful for planning mesh-networks and infrastructure networks on top of the access layer of a radio network. Between each two points, practically between every transmitter and receiver the linkbudget can be calculated, based on all typical rf parameters, including the channel bandwidth and minimum required C/I. Due to its integration with the link budget it is possible to calculate directly with the directed antenna gain of each antenna. Based on the calculations the following results are available: eirp as a result of transmitted power, antenna gains and losses Receiver sensitivity as a result of receiver's noise figure, thermal noise and channel bandwidth Total available path loss dB as a result of Tx eirp. Permitted propagation loss dB as a result of total available path loss and dimensioning figures Maximum (free-space) cell range m Terrain-Profiler The terrain profiler is designed to support the analysis of point-to-point connections and for line-of-sight analysis.

It is designed for suburban - urban areas and considers three non-Line-of-Sight (nlos)-scenarios - a, b and. A - hilly, medium to high vegetation b - hilly, low vegetation or flat with medium to high vegetation c - flat with little vegetation (also for urban areas) cost-231 Walfisch-ikegami itu-r.1411-3 is a semi-empirical model based on cost 231 Walfisch-ikegami and enhanced. The model considers detailed input data like average height and separation of buildings, street data (width, direction bs and ms antenna height, length of the path covered by buildings as well as distance from bs. Corla (3d-raylauncher) corla - a cube Oriented ray launching Algorithm - uses a discrete cube based representation of the supplied area that leads to a fast identification and processing of diffraction and reflection sources. Different antenna patterns, delay spread and building penetration are inherent features of the algorithm. Corla is licensed by tnc (Telecommunication Network consulting).
Based on corla, tnc offers powerful decision support modules for umts network planning, like bts_Opt. For more information visit m or contact. Calculation visualization With the help of the various prediction models a planned network can be analyzed in detail without having it deployed. In particular different planning versions can be compared and modified, re-calculated and optimized with teh help of different visualization methods and topics. For different network types the required methods differ a lot. While for mobile networks audrey areal predictions are most important, last-mile networks rather require detailed methods to investigate the single links to customers' premises.
It includes Location of sites (coordinates) Carriers implemented at the site Antennas (type, height) main-lobe direction, mechanical tilts, power per carrier or subcarrier Additional losses/gains (e.g. Cable loss) Receiving units can be represented as any pixel in a 2D-calculation visualization or as dedicated objects as "points" or "clients". Points are characterized by its coordinates and its receiver height. It is possible to calculate the receiving level for each point or even for a subset of them and to export it in a csv-formatted file. For last-mile networks (fixed-line substitution by wireless) often outdoor antennas with significant antenna gains and high receiver heights are used.
Wimap-4G supports the planning of such scenario with the help of "clients". Apart from "points" these objects are characterized by the supported carrier and antenna gains. It is possible to calculate the receiving level for each client or even for a subset of them and to export it in a csv-formatted file. Propagation Models wimap-4G comes with the built-in Free-space-Propagation, cost-231 Walfisch-ikegami and Erceg model and has an interface to the industrial-strength ray-launcher corla. Freespace The Free-space-Propagation model is primarily based on the elevation model. Optionally it takes into account visibility restrictions regarding the elevation model and the building model. While this model is not well-suited for city centres and strongly cultured regions, it produces good results for suburban and rural regions. It can help you to identify critical regions where detailed measurements should be done. Erceg (a,b, c) The ieee 802.16.3c proposes this model developed by victor Erceg for wimax planning.

Based on these technologies the wimap-4G user may add so called "carriers which represent typically one carrier frequency or a frequency band. Transmitters using the same carrier frequency, in particular those of the same carrier are assumed to interfering each other, while transmitters of different carriers don't. Many carriers may exist for the same technology, the number is not limited. For each carrier channels (e.g. Pilot channel) may exist. These can be represented by so called sub-carrier. Sites, Clients, points Basic objects in a radio network are the network transmitting units base stations" or "access nodes and the receiving units (mobiles or cpes - customer premise equipment). In wimap-4G network transmitting units are represented as "sites". Site data is required for every propagation prediction.
Topographical data (eelevation) is required for every field strength prediction, mainly for detection of "line-of-sight" and for the calculation essay of reflections and shadows. This data is expected to be available in asciigrid-formats (arcinfo, esri) or basic x-y-z lists. Wimap-4G offers also a direct interface to load srtm (elevation) directly from the web. Building data is used by the high-precise propagation prediction model corla, for considering indoor-loss considerations, and for advanced Line-of-Sight considerations. The data is expected to be available as mif-files (MapInfo). Building data can also be generated from vector-orientated data (2.5d - building data) and vice-versa building data can be used as maps. Also manual creation is supported. Carrier wimap-4G supports several current radio technologies, like gsm, umts, lte, wimax, wifi. A particular focus is on site-to-side and last mile technologies like wimax based on ieee 802.16(d,e wlan based on ieee 802.11 (a,b, g) and Micro-wave technology.

Therefore wimap-4G has several options to integrate this knowledge into the planning project as pointed out in the three subsections below. Maps, Elevation buildings wimap-4G supports cartesian (utm, gk) and geographical (WGS84) coordinates. Geographical data is provided typically as raster data (like formats as tiff, gif, jpg or png) or as vector-orientated data (DXF: Autocad, autodesk). For a fast orientation an online access to OpenStreetMap is directly integrated.
