PromotionCode.org was founded in 2008 by Mike Catania while he was a part-time music technology instructor at the Florida State University. Originally, the site was an online forum and coupon rewards website for teachers.
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
Wideband RF monitors can be used at a broader variety of base station sites than for example a narrowband, cellular RF monitor which is designed only to be used in the mobile telephone- and data networks. IEEE Std C95.3 states that "In the region between 1-100 GHz, resistive thermoelectric dipoles are used as sensors with a background of lossy ...
There is an international standard, IEC 62037 "Passive RF and microwave devices, intermodulation level measurement", for measuring intermodualtion distortion of passive components. Testing to the standard ensures that specifications from different manufacturers are done under the same conditions and can be compared with each other. [ 6 ]

Radio-frequency identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a tiny radio transponder called a tag, a radio receiver, and a transmitter.
More than one million delivery drivers collectively paid more than $10 million in fees after Walmart and Branch Messenger illegally opened costly deposit accounts in their names without consent ...
The waveguide E band is the range of radio frequencies from 60 GHz to 90 GHz in the electromagnetic spectrum, [1] [2] corresponding to the recommended frequency band of operation of WR12 waveguides. These frequencies are equivalent to wave lengths between 5 mm and 3.333 mm. The E band is in the EHF range of the radio spectrum.
