-Ham radio frequency bands are bands you're allowed to transmit on if you have a license. Note: there are non-ham radio bands which everyone is allowed on (example: PMR446). Also, some ham radio bands are shared with other non-ham radio things (example: ISM @ 433.05 - 434.57 MHz and 2.4-2.5GHz, also WiFi/Bluetooth/microwaves). Of course you can use your ham radio equipment to use these public bands, but keep an eye on power!

+It is not allowed to use ham radio equipment on for example PMR bands! On ISM bands all equipment needs to be CE certified which ham radio equipment is not!

 Each band is referred to by it's approximate wavelength. Not exact (example: 40m band has a wavelength 41.6-42.8m). Mention λ[m] = 300/(f[MHz]) as rule of thumb!
