Another issue may have been that the plane and helicopter could have been talking on different frequencies, Mr Coffield said. "The helicopter is talking on UHF frequencies, which the military uses, and the airlines are talking on VHF. The tower talks to both at the same ...
These two communicate over Bluetooth using ultra-high frequency (UHF) radio waves – electromagnetic waves with frequencies of around 2.4GHz (2.4 billion waves per second). If you have ever wondered what Bluetooth is named after, the answer isn't something you would correctly guess and scrib...
These spy devices resemble regular sunglasses or spectacles but conceal a hidden camera within their frame or, in some cases, the lens itself. The electronics are similar to those found in spy pen cameras, with the camera and circuitry discreetly integrated into the glasses’ frame. Some spy sh...
Today, the codes are declassified and widely used in the classification of wave bands. Low Band HF, VHF, UHF and L operating in 3 MHz-2 GHz Frequency Radars using this portion of the electromagnetic spectrum are particularly effective at long-range target detection of challenging targ...

The RFID is a wider area with other frequencies like the UHF where SpringCard develops a new offer, and the world of the active RFID where in lots of situations the old proprietary systems are replaceable by BLE systems. Published on 9/11/2018...
802.11af enhances the 802.11 WLAN PHY to support operation in the TV white space (TVWS) spectrum in the VHF and UHF bands. It introduces a new Television Very High Throughput (TVHT) PHY to accommodate the narrow TV channels that are available in the TVWS spectrum. In addition to OFDM, ...
To uniquely identify a tagged item, each RAIN RFID tag contains a number that corresponds to that item in a database. RAIN RFID readers, which operate at ultra-high radio frequencies (UHF), can read up to 1,000 individually tagged objects in one second. ...
