bandwidth of microwaves/radiowaves/infrared (1 Viewer)

Can anyone tell me the bandwidth for microwaves/radiowaves and infrared?
Different websites state different things.

Thanks

Most wireless applications frequencies 1GHz > 30GHz are used
Microwaves closer to 15GHz - satellite TV eg. Foxtel 12.4GHz.
Mobile phones 1GHz > 2GHz
Bluetooth + current 802.11g WLANs 2.4GHz.
GPS 1GHz > 1.5GHz.
Infrared waves occur above microwaves and below visible light. For communication
systems, frequencies just above microwaves are used. Infrared waves travel in straight
lines hence a direct line of sight is required between source and destination. Currently
infrared is only used over short distances.

think we'll need to memorise this? Seems too specific.
