web-BASED application for Radio Frequency network planning

Spectrum-E offers RF network planning via a web application. Compatible with ATDI’s flagship radio planning and modelling tool, ICS telecom EV.

Spectrum-E is a tablet-friendly web application for planning radiocommunication networks and performing frequency analysis in the MF to UHF bands. Users select different templates specific to the technology they are using. Customized templates can be prepared on request, depending on the types of analysis required.

Spectrum-E enables engineers to plan and model in the field or remotely. Spectrum-E uses a HTML5-capable web browser (tablet, computer or smartphone) and an internet connection (WiFi, cellular or LAN connection). It produces fast and accurate results for almost any environment.

Spectrum-E offers a direct connection to a dedicated ATDI data centre, where users can perform a variety of engineering simulations including multi-station composite coverage analysis (using high-resolution terrain and clutter), frequency nomination analysis and interference studies – all at the touch of a button.


Web-applications offer specific advantages over local software applications:
• Zero footprint on computer resources (i.e. SSL access)
• Cross-platform compatibility including agnostic operating-systems and compatibility with all browsers (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
• Maintenance available as well as upgrades.

Spectrum-E is compatible with any HTML5 web browser (inc Google Chrome, Mozilla Firefox v9+, IE v9+, Safari, Opera). ATDI recommend Google Chrome for the best results. Spectrum-E is a tablet-friendly web application.


Spectrum-E can be licensed in several ways:

• Subscription: allowing customers to access hosted licenses via ATDIs’ servers
• Local Area Network (LAN): Spectrum-E a can installed on the end-users’ internal network
• Standalone Computer: Spectrum-E can be installed on an individual users’ computer.
