Does the IC 7300 have a CW decoder? Nope. And pretty much every software designed for decoding CW doesn't work very well with real world signals sent by humans in less than perfect conditions. What is the most popular ham radio digital mode? Overview FT8 - In 2018 it is by far the ...
NFC: A Subset of RFID A type of RFID (radio frequency identification), NFC is limited to communication within the aforementioned 10 cm range; however, some forms of RFID can be read at a much larger distance. NFC specifically refers to a branch of high-frequency (HF) wavelengths within the...
What is a hologram and how does it work? Laser beams are split up in order to construct a hologram, causing the light waves that make up the two parts of the beam to travel in similar fashion. It is due to this that the image seems to change. This is also what lends holograms thei...
Each radio frequency has associated standards, including ISO 14223 and ISO/IEC 18000-2 for LF RFID, ISO 15693 and ISO/IEC 14443 for HF RFID, and ISO 18000-6C for UHF RFID. Next-generation RFID use RFID systems are becoming increasingly used to supportinternet of thingsdeployments. Combining ...
“We knew it was important to create an HF radio network,” says Roberts. Over the past nearly two decades, the TEMA team has worked systematically to implement the best practices, as laid out by the UN. There are additional efforts underway to create an interconnected region-wide radio netw...
How Does a Laser Pointer Work? The Basics of an Atom An atom, in the simplest model, consists of a nucleus and orbiting electrons. HSW There are only about 100 different kinds of atoms in the entire universe. Everything we see is made up of these 100 atoms in an unlimited number...
How does RFID work? The so-called air interface refers to the transmission of data via the medium of air by means of electromagnetic waves. The transmission method of the air interface (reader ↔ transponder) differs between LF/HF RFID and UHF RFID. LF/HF RFID LF and HF RFID operate on...
