iQ·linkXG
Key Features

Multi-Platform Compatibility
iQ·link®XG is built on the multi-platform Qt framework. This allows the software to be installed directly on multiple operating systems including both Microsoft Windows—and Sun Solaris (UNIX) servers and PCs. This framework also offers a new, modern, user-friendly interface that further enhances the user's interaction with the software.

Adaptive Modulation (ADM)

Comprehensive Support for Adaptive Modulation (ADM) Radios:
The result of numerous discussions and meetings with major operators and equipment manufacturers, iQ·linkXG offers the most comprehensive functionality to support the design of microwave links with adaptive modulation radios including:

• Simple and flexible import of numerous Adaptive Modulation radios through the use of a standardized spreadsheet format.
• Highly customizable link designs with Voice/Data analysis (High Priority/Low Priority traffic).
• Option to report Outage/Unavailability statistics based on the specified Priority and Non-Priority traffic distribution.
• Full Consideration of:
• ADM Power Adjust
• ADM Power Boost
• Modulation Downshift offset
• Modulation Upshift offset
• Full implementation of ADM with Automatic Transmit Power Control (ATPC).
• Availability and Performance calculations for all modulations.
• Detailed interference analysis with the ability to automatically detect the worst-case modulation combination of interfering transmitter and victim receiver.

Network View

Network View Module
Network View provides a multi-faceted interface that allows the user to graphically represent all or any part of the microwave network.

Links and sites can be displayed, as well as information regarding each component, including frequencies, capacities, channelization plans, high-low configuration, and other details of the system. The Network View module provides a rapid overview of the network architecture and allows the engineer to perform many rapid engineering assessments such as quick point-to-point link clearance analysis and global line-of-sight studies from a single site with overlap region definition from multiple sites.

Users have the ability to visualize environmental factors such as terrain, morphology, and clutter layers, as well as buildings, map, aerial imagery, vector data and other layers.

Several Engineering functions can be accomplished directly from this utility including quick and detailed link profiles, rapid Line of Sight (LOS) analysis and reporting, site creation, chain reliability calculations and Coverage and C/I analysis for PMP systems.

Engineering

Quick Link Budget Design
iQ·linkXG enables rapid creation of Point-to-Point (PtP) or Point-to-Multipoint (PMP) links.

Links may be saved as working designs (nominal), primary designs or confirmed (password protected, on-air) links.

This engineering window provides a one-page summary of all of the necessary microwave link elements, enabling the user to build the link and make changes without the need to sort through a clutter of multiple windows.

Detailed Path Profile Analysis

Profile Anti-correlation

iQ·linkXG's Profile Module generates a terrain profile between two sites to determine the line-of-sight (LOS) characteristics of the proposed link. The terrain profile can also incorporate clutter data such as buildings and vegetation.

Digitized terrain profiling allows the microwave design engineer to accurately optimize antenna heights for proper path clearance, while avoiding potentially harmful reflections.

Results of the profile are shown both graphically and numerically for flat earth and up to three values of earth curvature (K-factor) and link clearance (Fresnel zone) criteria. The K-factors and Fresnel zone values are user-specified, and can be easily changed as necessary.

Morphology, user-definable clutter and even high resolution building data can be incorporated into the path profile.

Anti-Correlation analysis provides the user with the ability to determine the ideal primary and diversity antenna spacing required in order to counter multipath propagation effects (based on ITU-R P.530).

Design

Availability and Performance Assessment
iQ·linkXG performs link availability and performance calculations using industry standard propagation and objective models including Vigants, Glauner, ITU-R P.530-6, ITU-R P.530-7, ITU-R P.530-8, ITU-R P.530-9, ITU-R P.530-10, ITU-T G.821 and G.826, Crane, ITU-R P.837-3, ITU-R P.837-1.

Interference Case Details

Interference Analysis
iQ·linkXG's detailed, efficient interference analysis, calculates the interference potential from a proposed new link against the database of all previously stored primary designs and confirmed links. Both Point-to-Point and Point-to-Multipoint systems are considered simultaneously.

A Cumulative interference analysis is offered in order to predict the amount of degradation caused by the cumulative interference of a maturing network.

Other options include the ability to utilize 3-D antenna patterns when available, predict diffraction loss along interference paths due to obstacles and relax interference objectives due to correlated fading in bands where rain is the primary fading mechanism.

TX Spectrum & RX Selectivity

Detailed interference objectives between any combination of interfering and victim radios are quickly derived using Tx Spectrum masks and Rx selectivity curves provided by the manufacturer or ETSI defaults. The interference objective matrix stores the results for every interfering-victim combination so that these intensive calculations are only done once. This results in a very fast interference analysis.

AFP Utility

Automatic Frequency Planning (AFP)
iQ·linkXG provides the user with the ability to perform automatic frequency planning. Detailed criteria can be set so that the final result meets your network design needs. In addition, this module incorporates a sophisticated high/low conflict resolving algorithm. Combined with the speed of iQ·linkXG native calculation algorithm, this feature can significantly improve on design efficiency and time.

Point-to-Multipoint Design

Point-to-Multipoint Design Functionality
iQ·linkXG supports the design of Hub-Subscriber links that are required to implement such networks as Wireless Local Loop (WLL), Local Multipoint Distribution Service (LMDS), and other point-to-multipoint (PMP) applications.

The network view module offers a color-coded plot of receive signal level (RSL) and interference (C/I) which may be displayed for selected hub sites within the Network View. The user controls the color-coding scales. It is possible to visualize locations around hub facilities where acceptable coverage and interference-free operation are available.

Both omni-directional and sectorized antennas are supported with the ability to enter and utilize antenna pattern data in both the azimuth and elevation planes.

When combined with high-resolution terrain and building data, design and analysis of point-to-multipoint networks is fast and simple.
