Regulation 7 Slave device requirementsI1

United Kingdom

(1)

A slave device must only transmit within the frequency band 470 MHz to 790 MHZ—

(a)

after receiving slave operational parameters from a master device which are either—

(i)

parameters for use by all slave devices operating in the coverage area in which communications from the master device can be received (“generic slave operational parameters”); or

(ii)

parameters that are specific to a particular slave device (“specific slave operational parameters”);

(b)

in accordance with the limitations specified in slave operational parameters which have been communicated by a master device; and

(c)

on the specific frequencies and within the specific power limits specified in channel usage parameters that have been determined—

(i)

by the slave device and communicated to a master device; or

(ii)

by a master device for the slave device.

(2)

If a slave device operates simultaneously on more than one DTT channel and if indicated by the slave operational parameters, a slave device must also apply a simultaneous operation power restriction.

(3)

A slave device must cease transmitting if the slave operational parameters it has received are no longer valid.

(4)

Slave operational parameters cease to be valid if—

(a)

the slave device receives an instruction to cease transmissions from the master device from which it has received its slave operational parameters; or

(b)

the slave device has not received any transmission from the master device from which it has received its slave operational parameters for longer than five seconds.

(5)

A slave device which transmits using generic slave operational parameters must communicate to the master device which has communicated those parameters—

(a)

information specifying that the device is a slave device; and

(b)

the slave device’s unique identifier.

(6)

If a slave device requests specific slave operational parameters from a master device, it must communicate to the master device when requesting those parameters the following information (“slave device characteristics”)—

(a)

information specifying that it is a slave device;

(b)

the slave device’s unique identifier;

(c)

information specifying that the slave device is Type A equipment or Type B equipment;

(d)

the location of the slave device expressed as the latitude and longitude coordinates of the location of its antenna; and

(e)

the geo-location uncertainty of its antenna.

(7)

Except where paragraph (8) applies, after receiving slave operational parameters from a master device, a slave device must communicate its channel usage parameters to that master device.

(8)

This paragraph applies if the channel usage parameters for a slave device have been determined by the master device.
