While benefitting from a derogation, Member States are obliged to ensure that their temporary continued use of the 800 MHz band (for broadcasting purposes, for example) does not hinder the development of wireless broadband in that band in neighbouring Member States.
Kuigi sagedusala suhtes kehtib erand, on liikmesriigid kohustatud tagama, et 800 MHz sagedusala ajutine jätkuv kasutamine (näiteks ringhäälinguteenusteks) nende poolt ei takista traadita lairibaühenduse arendamist kõnealusel sagedusalal naaberliikmesriikide territooriumil.
