A subcarrier is a secondary modulated signal frequencymodulatedinto the main frequency (the carrier) to provide an additional channel of transmission. It allows for a single transmission to carry more than one separate signal. It is most commonly used in radio frequency (RF) transmissions but can...
What is Sub-GHz? Wi-Fi, Bluetooth, and ZigBee technologies are 2.4 GHz protocols widely used in today’s wireless communication applications. The Sub-GHz protocol works in a different radio frequency, below the 1 GHz band. Sub-GHz is one of the essential technologies for wireless communication...

The electromagnetic spectrum consists of many subranges of frequency bands, such as radio waves, microwaves, X-rays,infraredrays and gamma rays. Each subrange falls under a specific frequency band. The ITU helps regulate the transmission of frequency bands along with any regulatory laws of the cou...
khz is a unit of frequency equal to 1,000 cycles per second. it is commonly used to measure frequencies in various fields, including technology, computing, programming, and communications. how does kilohertz relate to sound? in the context of sound, kilohertz represents the frequency of audio ...
specific groups of frequencies in the RF spectrum, or bands, are used. These bands can be further grouped into a range of subfrequencies, called channels. The use of frequency bands and channels for specific applications, such as Wi-Fi, TV, radio, and air traffic control, is regulated by...
This original amendment added support for the 5 GHz band, allowing transmission up to 54 megabits of data per second. The 802.11a standard makes use of orthogonal frequency-division multiplexing (OFDM). It splits the radio signal into sub-signals before they get to a receiver. 802.11a is an...
the powerline adapter works by taking electricity from an electrical outlet and transforming it into a radio frequency signal that is then transmitted by the adapter over your existing wiring. this allows you to use the same outlet as both an input for power and an output for data transmission...
aThis equipment is intended for use in a laboratory test environment only. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to subpart J of part 15 of FCC rules, which are designed to provide reas...
Significantly reduce the antenna size: When the antenna transmits and receives radio electromagnetic waves, the antenna size must be equal to the wavelength of the signal (the antenna size is greater than 1/4 wavelength). For example, for a voice signal (20 Hz to 20 kHz), a corresponding ...
