When considering the range of radio frequencies for satellite communications, say from around 300 MHz to 30 GHz, the free-space wavelength varies from 1 m to 1 cm .
Read moreWhat is the bandwidth of satellite?
Internet via satellite phone Bandwidth varies from about 2400 bit/s for Iridium network satellites and ACeS based phones to 15 kbit/s upstream and 60 kbit/s downstream for Thuraya handsets .
Read moreWhat is the bandwidth of a typical satellite transponder?
The bandwidth of a typical transponder is 36 MHz . If we employ 12 such transponders with 4 MHz of guard band between each transponder, then accommodation of 12 transponders in 500 MHz bandwidth is achievable.
Read moreWhat is the range of RF frequency?
Radio frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz .

Read moreWhat are the frequency ranges for LW MW and SW?
Sometimes a division by wavelength is used: Short wave (SW): Wavelengths of 10-200m hence frequencies of 1.5-33 MHz ; there are several sub-bands. Medium wave (MW): Wavelengths of 200-1000m hence frequencies of 300 kHz-1.5 MHz. Long wave (LW): Wavelengths > 1000m hence frequencies < 300 kHz.
