Extremely low frequency or ELF refers to the band of radio frequencies from 3 to 300Hz.
Very low frequency or VLF refers to radio frequencies (RF) in the range of 3 to 30 kHz.
Low Frequency or LF refers to Radio Frequencies (RF) in the range of 30-300 kHz.
Medium frequency or MF refers to radio frequencies (RF) in the range of 300 -3000 kHz.
High frequency (HF) radio frequencies are between 3 and 30 MHz.
Very high frequency (VHF) is the radio frequency range from 30 MHz to 300 MHz. Common uses for
VHF are FM radio broadcast at 88-108 MHz and television broadcast.
Ultra high frequency (UHF) radio frequencies are those between 300 MHz and 3.0 GHz.
Extremely high frequency is the highest radio frequency band included in the range of frequencies from
30 to 300 gigahertz.
IEEE 802.11 or Wi-Fi is a set of Wireless LAN standards developed by working group 11 of IEEE 802.
This includes three separate versions: 802.11a operates at 5.2GHz and 5.5GHz, 802.11B operates at
2.4GHz and 802.11G operates at 2.4GHz.
L band a portion of the microwave band of the electromagnetic spectrum ranging roughly from 950 MHz
to 2.5 GHz. It is used by some communications satellites.
S band a part of the microwave band of the electromagnetic spectrum ranging roughly from 1.55 to 5.2
GHz where 2.3 GHz is currently used by Sirius Satellite Radio and XM Satellite Radio.
C band a portion of electromagnetic spectrum in the microwave range of frequencies ranging from 4 to 6
GHz. C band is primarily used for satellite communications, normally downlink 3.7 –4.2 GHz horizontal
polarization, uplink 5.9–6.4 GHz vertical polarization,
X band in the microwave band of the electromagnetic spectrum roughly ranges from 5.2 –10.9 GHz.
K band a portion of the electromagnetic spectrum in the microwave range of frequencies ranging between
12 to 40 GHz.
The K band a portion of the K band of the microwave band of the electromagnetic spectrum ranging from
a
18 to 40 GHz.
The K band a portion of the electromagnetic spectrum in the microwave range of frequencies ranging
u
from 11 to 18 GHz. K band is primarily used for satellite communications.
