Read moreWhat does L band mean?
Long-wavelength band (L-band) The L-band, ranging from 1565 nm to 1625 nm, stands for the long-wavelength band (see Figure 1). It is the second primary wavelength band used for optical communication, because attenuation of optical fiber in the L-band is the second lowest after the C-band.

New material! BandFrequency RangeOrigin of NameL0.5 to 1.5 GHzL for “long” wave.S2 to 4 GHzS for “short” wave. Don’t confuse this with the short wave radio band, which is much lower in frequencyC4 to 8 GHzC for “compromise” between S and X band.X8 to 12 GHzUsed in WW II for fire control, X for cross (as in crosshair)Frequency Letter Bands – Microwaves 101 www.microwaves101.com › encyclopedias › frequency-letter-bands

Read moreWhat is band 2 radio?
Band II is the range of radio frequencies within the very high frequency (VHF) part of the electromagnetic spectrum from 87.5 to 108.0 megahertz (MHz) .
Read moreWhat is band channel?
A “channel” refers to a portion of a band which in the case of the TV Band is around 8MHz wide . Other bands have smaller or larger channels depending on their use, varying from 9KHz for AM radio up to 30MHz for a satellite TV transponder.
Read moreWhich is stronger VHF or UHF?
VHF has smaller frequencies which means interference with other radios is common. UHF, on the other hand, is an all-around better signal for long distance communication . UHF is better when using radios for indoor use like buildings or around cities.12 Mar 2019
