Aircraft navigation- As RF is categorized between different bands, for aircraft navigation, VHF (Very high frequency) are used. As aircrafts fly on 1500 ft and to communicate at such a high level you need a very high-frequency band.  

Satellite systems- SHF (super high frequency) is in the range of 3 GHz to 30 GHz. It can only operate in a line of sight path since any obstruction in between the transmitter and receiving station will break the communication. In the case of satellite communication, SHF is required as it needs point to point communication and there is a great chance of loss of signals. In addition, the wavelength and the complexity both are short in case of SHF.

Marine radio- In marine radio VLF is used that range from 3 kHz to 30 KHz. The design and installation of the antenna system are quite complex due to the wavelength. It is used in submarines, radio station that synchronizes clock signals between two remote locations.

Mobile networks- Low frequency (LF) has a range from 30 KHz to 300 KHz used for mobile networks. LF is easily reflected by the ionosphere present above the earth. This can be easily used for long distances communication purposes. It gets less attenuated from the large and harsh terrains such as mountains. It is also known as ground waves.
