WEB-BASED APPLICATION FOR SPECTRUM MANAGEMENT AND ENGINEERING

ATDI introduces Spectrum-E, the company’s latest web-based spectrum engineering and management software for civil and defence markets.

With three-decades of radio planning and spectrum engineer software behind it, ATDI offers its latest radio engineering software, Spectrum-E. This software is the latest product added to its product portfolio, giving users the options to access it as a SaaS subscription model or a perpetual/concurrent user license model.

Spectrum-E provides the flexibility to plan and model in the field, from the office or at the end user’s site.  The application supports cross-platform compatibility between mobile and PC devices.

Spectrum-E SaaS option enables customers to use the abundant computer resources available via ATDI’s secure cloud server to perform simulations in a matter of minutes. Features include multi-station composite coverage analysis (using high-resolution terrain and clutter), frequency nomination and interference studies – all at a click of a mouse.

MODULES

Since its development, considerable resources have been invested into Spectrum-E, providing a must-have toolkit for every radio engineer. The software is supplied in three separate modules, which can be operated singularly or as part of one integrated solution:

  • e-Licensing
  • Technical Analysis
  • Remote Monitoring

Technical Analysis Module

This module focuses on spectrum engineering and features the following functions:

  • Propagation analysis
  • Interference analysis
  • Electromagnetic compatibility analysis
  • Frequency coordination
  • Frequency nomination
  • Population coverage analysis.

The Technical Analysis module includes access to a repository of digital terrain models, land cover and ground conductivity maps for the entire planet.  The user can also upload data in vector format (lines, points, polygons) in SHP or KML/KMZ formats.

In addition, the Technical Analysis module offers significant benefits in terms of non-functional benefits, including:

  • Distributing task orders over multiple cores (true parallelism)
  • Accessing a continuous, single projection map of the planet (removing the need to “load” maps limited to 2 UTM zones)
  • Managing 10,000 or more emissions during a single analysis.

e-Licensing Module 

The e-Licensing module allows an applicant, or an existing licensee, to prepare and submit applications for spectrum through an online portal. In addition, it enables the regulator to receive, validate and continue to process the application through the same platform, reducing the complexity and duplication of licensing and improving speeds. The e-Licensing module leverages Spectrum-E’s Business Rules Engine (BRE) to help assign a library of rules to automate the validation process of the in-coming application, wherever possible. The BRE engine works with the e-Licensing module workflow management capabilities to process the data included with the in-coming applications.

Monitoring Module

Spectrum-E supports leading spectrum monitoring equipment vendors including Rohde & Schwarz, TCI, Anritsu and Keysight. This module enables users to perform remote spectrum monitoring tasks by activating requests to launch monitoring and measurement campaigns directly from the monitoring system’s interface or, in some cases, directly to the monitoring equipment itself via a socket layer connection. This module allows the user to store measurement results, once returned by the spectrum monitoring system, in the Spectrum-E database. This module allows the user to output these results into various graphs and ITU compliant reports.

Access to Spectrum-E

Spectrum-E can be licensed in several ways:

  • Subscription: accessed via ATDI’s dedicated servers and available on a monthly subscription rate
  • Local Area Network (LAN): installed on the end-user’s internal network on a perpetual license basis
  • Standalone Computer: installed on an individual user’s computer on a perpetual license basis.

Benefits of web-applications

Web-applications offer specific advantages over local software applications:

  • Zero footprint on computer resources (i.e. SSL access)
  • Compatible with all browsers and technology agnostic operating-systems (tablet, PC or smartphone)
  • Distribute information to large groups instantly from a database (multi-resolution map databases, relational databases, equipment databases)
  • Customizable and integration friendly, allowing work flow automation with dedicated interfaces
  • Feature software maintenance package as well as upgrades.

Spectrum-E is compatible with any HTML5 web browser. ATDI recommends Google Chrome for the best results. Spectrum-E is a tablet-friendly web application.

Architecture and Distribution

Spectrum-E is developed utilizing the latest open-source web technologies.  As an n-tiered web application, its presentation-layer leverages the advantages of the latest web technologies such as HTML5, CSS, JavaScript, E-commerce, Single Page Applications (SPA), WebGL and Scalable Vector Graphics (SVG), as well as ongoing development to incorporate evolving new technologies (i.e. HTML6, Progressive Web Apps, etc.).  By embracing the latest web technologies Spectrum-E can adapt to the rapidly evolving web technology landscape, enabling ATDI bring this cutting-edge software solution to market.
