Deep space bands

Deep Space Bands and Near Space Bands are frequency bands that have been allocated to the space research service by the International Telecommunication Union for use in deep space and near Earth research.^[1]

Frequency allocations in MHz
Band Designation	Deep Space Bands (for space stations more than 2,000,000 km from Earth)		Near Space Bands (for space stations less than 2,000,000 km from Earth)
Band Designation	up-link (Earth to Space)	down-link (Space to Earth)	up-link (Earth to Space)	down-link (Space to Earth)
S band	2 110–2 120	2 290–2300	2 025–2 110	2 200–2 290
X band	7 145–7 190	8 400–8 450	7 190–7 235	8 450–8 500
K band	*	*	*	25 500–27 000
Ka band	34 200–34 700	31 800–32 300	*	*
