GD upgrading Navy shipboard radio with HF automatic link establishment
Automatic Link Establishment (ALE) is crucial to channel assignment and data exchange in HF radio networks. The link establishment interval and quality are two main concerns in this context. In jamming environments, the jammer signals seriously influence the channel quality.

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.
(PDF) Automatic link establishment for HF radios
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 (ALE) is a technology that takes the guesswork out of choosing the best frequency to use to contact a specific station. Stations on an ALE network periodically send out a signal that identifies the station. This is called sounding.

What is ALE? Automatic Link Establishment, usually abbreviated ALE, is a standard for digitally initiating and sustaining radio communications on HF.
DOWNLOAD Four Generations of Automatic Link Establishment An HF
Automatic Link Establishment ( ALE) is the principle where a specialized radio modem, known as an ALE adaptive controller, is assigned the task of automatically controlling an HF receiver and transmitter in order to establish the highest quality communication link with 1 or multiple HF radio stations.
PPT Automatic Link Establishment for Amateur Radio Status Report
One of the important developments in the HF communication is Automatic Link Establishment. ALE method is widely used by the military and other organizations. In this paper we have tried to describe the implementation of ALE military standard (188-141A). This standard defines a 2G HF ALE standard.

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

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.
