PPT Automatic Link Establishment for Amateur Radio Status Report
Automatic Link Establishment (ALE) was developed to provide for establishing best quality high frequency communications without the need for consulting propagation forecast information, or the need of having training to interpret propagation forecast information.
Automatic Link Establishment
ALE is the acronym for Automatic Link Establishment. ALE is the de-facto worldwide standard for initiating and sustaining communications using High Frequency radio. HF radio conveys signals via ionospheric propagation, a constantly changing medium.

With an unrivalled pedigree in HF communications, Leonardo has developed Third Generation Automatic Link Establishment (3G ALE) algorithms that ensure that links are automatically established and maintained to achieve successful trafic transfer without operator intervention. HF2000 monitors link quality and selects the best transmission frequency.

The ION2G software brings HF Automatic Link Establishment (ALE) MIL-STD-188-141B to your computer with a familiar and easy to use interface. ION2G helps you stay connected to the people you need to communicate with across thousands of miles without dependence on infrastructure.
Automatic Link Establishment (ALE) YouTube
Automatic link establishment (ALE) is one of the important technologies in HF communication. One of the indicators to measure the performance of an ALE system is the linking time, which includes channel switching, spectrum sensing, and trying to call three periods. Asynchronous mode has been widely used for its simple operation. When establishing an link, the station sorts all the channels and.

This paper examines existing automatic link establishment (ALE) techniques for high frequency (HF) radio systems, identifying areas of improvement in calling techniques and protocols for ALE. Automated HF radio systems improved in these areas have been implemented, and results of these implementations are presented. Compromises between link establishment time and reliability are also considered.

AUTOMATIC LINK ESTABLISHMENT Third-generation ALE (3G-ALE) is designed to quickly and efficiently establish one-to-one and one-to-many (both broadcast and multicast) links. It uses a specialized carrier-sense-multiple-access (CSMA) scheme to share calling channels, and monitors traffic channels prior to using them to avoid interference. Scanning
