Question

What is difference between l-band and c-band?

Answer 1

*C band is a name given to certain portions of the electromagnetic spectrum, as well as a range of wavelengths of light, used for communications. The IEEE C band and its variations, in particular, are microwave ranges used for certain satellite television broadcasts, and by some Wi-Fi devices, cordless phones, and weather radars.

-C Band is the original frequency allocation for communications satellites.

C-Band uses 3.7-4.2GHz for down link and 5.925-6.425Ghz for up link.

The lower frequencies used by C Band perform better under adverse weather conditions than the Ku band or Ka band frequencies.

-The NATO C band is that portion of the electromagnetic spectrum between 500 MHz and 1000 MHz.

-The IEEE C band is a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4 to 8 GHz.

-C band is primarily used for open satellite communications, whether for full-time satellite TV networks or raw satellite feeds, although subscription programming also exists. This use contrasts with direct broadcast satellite, which is a completely closed system used to deliver subscription programming to small satellite dishes connected to proprietary receiving equipment.

*The NATO L band is defined as the frequency band between 40 and 60 GHz (5–7.5 mm).

-The IEEE L band (20-cm radar long-band) is a portion of the microwave band of the electromagnetic spectrum ranging roughly from 1 to 2 G Hz.

It is used by some communications satellites, and for some terrestrial Eureka 147 digital audio broadcasting (DAB).

The amateur radio service also has an allocation between 1240 and 1300 MHz. The L Band refers to the frequency range of 950 MHz to 1450 MHz.

- It is the result of the down conversion of the received down link satellite signals (C or Ku) by the LNB (Low Noise Block converter).

Answer 2

C band as defined by the Radio Society (of Great Britain) and subsequently used widely by other authorities is:

4 - 8 GHz

Nato (North Atlantic Treaty Organization) also uses letter designators.

Nato's C-band is from 0.5 - 1 GHz

Nato's I-band is from 8 - 10 GHz

Nato is the only entity that uses the letter 'I' to designate a band.
