Spectrum Engineering is now online! Based on HTZ and ICS engines, ATDI's new RF network planning web application adds another dimension to the classic ATDI product line of desktop based software solutions. Spectrum-E is ATDI's tablet friendly web application for planning telecommunication networks and performing frequency nomination analyses for government and commercial networks operating in the MF through UHF bands. Customers can select from different templates specific to their technology of interest. Custom templates can be prepared per request. By connecting to ATDI's dedicated Data Center, ATDI customers can perform various engineering simulations such as a multi-station coverage analysis over 5 meter or 10 meter terrain and clutter, frequency nomination analysis, interference studies all within a minute each! Below are some examples of the features available in Spectrum-E for different radio technologies.

Web application advantages:

Web applications offer specific advantages over local software applications in the following areas:

  • Consumption of client computer resources: zero footprint implementation. (i.e. SSL access)

  • Cross platform compatibility: Operating system agnostic. Runs off of modern browsers. (i.e. tablet or PC or smartphone)

  • Ease of distribution of information: database information can be communicated to large groups of people very quickly and easily. (i.e: multi-resolution map databases, relational databases, equipment databases, etc.)

  • Customization and integration-friendliness: Work flow automation with dedicated interfaces. (i.e. import FCC ULS, WMS stream, integration with SpectrumWatch)

  • Maintenance: Upgrade distribution is immediate.


Spectrum-E is compatible with any HTML5 compatible web browser (Google Chrome, Moxilla Firefox v9+, IE v9+, Safari, Opera). Google Chrome is recommended for the best Spectrum-E experience. Spectrum-E is a tablet-friendly web application.

Access to Spectrum-E can be delivered in any of the following methods:

  • User Subscription: Customers will subscribe to access of Spectrum-E hosted on ATDI Inc's servers

  • Local Area Network (LAN): Spectrum-E and services installed on customer's internal network

  • Single Computer:, Spectrum-E can be installed on an individual user's computer


Security

ATDI Inc. uses 256-bit encryption along with a secure message authentication and key exchange mechanism to keep communication to Spectrum-E secure. For customers who don't have access to the internet in their working environments, Spectrum-E is also offered in an internal Local Area Network (LAN) or single computer flavors.

ATDI study: HF Analysis in Spectrum-E

ATDI, Inc. recently completed a HF (high frequency) analysis for the United States Coast Guard (USCG), analyzing the coverage capabilities of the existing US Customs and Border Patrol's (CBP) Customs Over The Horizon Enforcement Network (COTHEN) along with existing USCG HF sites nominated for potential inclusion in the existing COTHEN system. Using the most recent version of ITU propagation model 533 (Fig. 1), method for the prediction of the performance of HF circuits, the ATDI team was able to effectively model both existing and potential sites in the COTHEN network for coverage of expansive areas both on- and off-shore.

Through the use of point-to-point and point-to-area skywave coverage functions, the ATDI team was able to recommend an updated COTHEN layout designed to expand network coverage along with the bolstering of existing coverage reliability. The analysis considered the many complex characteristics of HF radio propagation including, but not limited to: seasonal variations, daytime/nighttime variations, sunspot numbers, receiver noise environments, required signal-to-noise values, distinctive antenna patterns with prominent vertical nulls, etc.

ATDI, Inc. also recently implemented a bevy of new high frequency (HF) functions into the Spectrum-E web application for the modeling of HF radio propagation. The added functions allow for both point-to-point and point-to-area analysis and the production of visual chart- and map-based result outputs. The ability to model multiple frequencies for one object or a network allows for simplified analysis of ALE (automatic link establishment) networks that frequency-hop through a frequency set, communicating on the most advantageous frequency at any one time. Map-based outputs also allow the user to fine-tune their results for presentation, allowing for both signal-to-noise based plots (Fig. 2) along with percentage of time of day plots (Fig. 3).

ATDI's Spectrum-E Featured in Public Safety Communications magazine

ATDI was recently featured in the August issue of Public Safety Communications magazine. The article highlights Spectrum-E as APCO AFC's advisors RF engineering tool for FCC Part 90 compliant propagation analysis and frequency coordination. "Spectrum-E is now the official tool used by APCO advisors to perform a variety of studies essential to supporting public safety communications networks on a local, state and national level."

The details of ATDI's contract delivery of the Spectrum-E web application to APCO International are featured in the recent article, Spectrum Engineering Goes Online. Some of the article highlights also include the applications's customization, user friendliness, efficiency, and functionality. "The collaboration with APCO has been exceptional, and the resulting platform reflects what best-in-class partners achieve when their efforts are pooled together. This step forward for our organizations and the RF engineering field in general promises great opportunities for many years to come," says Pierre Missud, CEO of ATDI Inc.
