Telecom Services in C- Band

In News 
  • India’s Aviation safety regulator (DGCA) has written to the telecom department flagging concerns over the likely interference of the 5G C-Band spectrum with aircraft radio altimeters.
Radio Altimeter 
  • A radio altimeter provides direct-height-above-terrain information to several aircraft systems.
  •  These altimeters as well as a part of the 5G telecom services operate in the C-Band and therefore risks interference. 
  • The radio altimeters pick up even the faintest signals, reflected off the ground in the assigned frequencies, to attain highly accurate results.
  • Therefore, the instruments can pick up 'out-of-band' signals, which could significantly impair the altimeters' functioning.
C- Band 
  • For telecom service providers, the C-Band presents a sweet spot for rolling out 5G services, ensuring coverage as well as high bandwidth, resulting in faster internet speeds. For aircraft operations, the use of altimeters in this band ensures highly precise measurements of the plane’s altitude.
  • However, experts say, India has auctioned the C-Band spectrum in frequency ranging from 3.3 GHz to 3.6 GHz.
  • Aircraft radio altimeters mainly use frequencies ranging from 4.2-4.4 GHz. So, there is a significant 500 MHz gap between the two frequency ranges.
