frequency allocation for satellite
Allocation of frequencies to satellite services s a complicated process which requires international coordination and planning. This is done as per the International Telecommunication Union (ITU). To implement this frequency planning, the world is divided into three regions:
Region1: Europe, Africa and Mongolia
Region 2: North and South America and Greenland
Region 3: Asia (excluding region 1 areas), Australia and south-west Pacific.
Within these regions, he frequency bands are allocated to various satellite services. Some of them are listed below.
- Fixed satellite service: Provides Links for existing Telephone Networks Used for transmitting television signals to cable companies
- Broadcasting satellite service: Provides Direct Broadcast to homes. E.g. Live Cricket matches etc
- Mobile satellite services: This includes services for: Land Mobile Maritime Mobile Aeronautical mobile
- Navigational satellite services : Include Global Positioning systems
- Meteorological satellite services: They are often used to perform Search and Rescue service Below are the frequencies allocated to these satellites:
Frequency Band (GHZ) Designations:
VHF: 01-0.3
UHF: 0.3-1.0
L-band: 1.0-2.0
S-band: 2.0-4.0
C-band: 4.0-8.0
X-band: 8.0-12.0
Ku-band: 12.0-18.0 (Ku is Under K Band)
Ka-band: 18.0-27.0 (Ka is Above K Band)
V-band: 40.0-75.0
W-band: 75-110
Mm-band: 110-300
μm-band: 300-3000 Based on the satellite service,
following are the frequencies allocated to the satellites:
Frequency Band (GHZ) Designations:
VHF: 01-0.3 —Mobile & Navigational Satellite Services
L-band: 1.0-2.0 — Mobile & Navigational Satellite Services
C-band: 4.0-8.0 — Fixed Satellite Service
Ku-band: 12.0-18.0 — Direct Broadcast Satellite Services
