Repeater equipment: GMSK Node Adapter - these devices are hardware GMSK modems with firmware to take D-STAR protocol frames over a USB cable and provide the necessary logic and GMSK modulation to control a simplex node or a full duplex repeater. One repeater that is easily adaptable is the Kenwood TKR-820 as documented by K7VE. [27]
In essence, a trunked radio system is a packet switching computer network. Users' radios send data packets to a computer, operating on a dedicated frequency — called a control channel — to request communication on a specific talkgroup.
Data transmission is utilized in computer networking equipment such as modems (1940), local area network (LAN) adapters (1964), repeaters, repeater hubs, microwave links, wireless network access points (1997), etc.
Jakeboard input software and hardware emulation keyboard and mouse was used by persons with physical limitations and/or problems of movements. [35] Software and hardware schemes are downloadable at BlackBeltSystems Amiga Software page. [36] Talkboard [35] similar to jakeboard, is a downloadable speech-generation system for persons.
The OSC carries information about the multi-wavelength optical signal as well as remote conditions at the optical terminal or EDFA site. It is also normally used for remote software upgrades and user (i.e., network operator) Network Management information. It is the multi-wavelength analog to SONET's DCC (or supervisory channel).
Kiwix Android App. Kiwix is a free and open-source offline web browser created by Emmanuel Engelhart and Renaud Gaudin in 2007. [9] It was first launched to allow offline access to Wikipedia, but has since expanded to include other projects from the Wikimedia Foundation, public domain texts from Project Gutenberg, many of the Stack Exchange sites, and many other resources.
A 2023 Communications of the ACM article [90] found that current quantum computing algorithms are "insufficient for practical quantum advantage without significant improvements across the software/hardware stack". It argues that the most promising candidates for achieving speedup with quantum computers are "small-data problems", for example in ...
The word television comes from Ancient Greek τῆλε (tele) 'far' and Latin visio 'sight'. The first documented usage of the term dates back to 1900, when the Russian scientist Constantin Perskyi used it in a paper that he presented in French at the first International Congress of Electricity, which ran from 18 to 25 August 1900 during the International World Fair in Paris.
