Regulation 12 Requesting operational parameters
A standard power access point or a fixed client device must request new operational parameters from the AFC system—
on each occasion when twenty-four hours have passed since operational parameters were last received; and
on each occasion when the standard power access point or fixed client device is powered on.
If, on the second or subsequent occasion a standard power access point or a fixed client device requests new operational parameters from the AFC system, it is unable to communicate with the AFC system, the most recent operational parameters may be used for one further period of twenty-four hours.
On expiry of that further period of twenty-four hours, the standard power access point or fixed client device, must cease operations until communication with the AFC system is re-established and new operational parameters obtained.
On each occasion before receiving operational parameters the access point or fixed client device must communicate to the AFC system (directly or indirectly) the following information (“device characteristics”)—
antenna geographic latitude and longitude coordinates and associated geo-location uncertainty
antenna height above ground level or above mean sea level in metres; and
the device’s unique device identifier.
A standard power access point or a fixed client device must be configured such that a user is unable to input, reconfigure or alter any AFC system related technical or operational settings or features of the device in a way which would alter the access point or device characteristics.
