Regulation 4 Terms, provisions and limitations

(1)

The exemption provided for in regulation 3 shall be limited to ultra-wideband equipment which satisfies the conditions set out in paragraphs (2) to (5) of this regulation.

(2)

The equipment is used—

(a)

indoors; or

(b)

other than indoors provided it is not attached to:

(i)

a fixed installation;

(ii)

a fixed infrastructure;

(iii)

a fixed outdoor antenna; or

(iv)

an automotive vehicle or railway vehicle.

(3)

The equipment does not cause or contribute to undue interference to any wireless telegraphy.

(4)

The equipment only emits transmissions at frequencies up to and including 3.4 GHz or at frequencies above 4.8 GHz which:

(a)

at frequencies below and up to and including 1.6 GHz when measured in any direction have:

(i)

a maximum mean e.i.r.p. density no greater than -90.0 dBm/MHz; and

(ii)

a maximum peak e.i.r.p. no greater than -50.0 dBm or the equivalent transmission level;

(b)

at frequencies between 1.6 GHz and up to and including 3.4 GHz when measured in any direction have:

(i)

a maximum mean e.i.r.p. density no greater than -85.0 dBm/MHz; and

(ii)

a maximum peak e.i.r.p. no greater than -45.0 dBm or the equivalent transmission level;

(c)

at frequencies between 4.8 GHz and up to and including 6.0 GHz when measured in any direction have:

(i)

a maximum mean e.i.r.p. density no greater than -70.0 dBm/MHz; and

(ii)

a maximum peak e.i.r.p. no greater than -30.0 dBm or the equivalent transmission level;

(d)

at frequencies between 6.0 GHz and up to and including 8.5 GHz when measured in any direction have:

(i)

a maximum mean e.i.r.p. density no greater than -41.3 dBm/MHz; and

(ii)

a maximum peak e.i.r.p. no greater than 0.0 dBm or the equivalent transmission level;

(e)

at frequencies between 8.5 GHz and up to and including 10.6 GHz when measured in any direction have:

(i)

a maximum mean e.i.r.p. density no greater than -65.0 dBm/MHz; and

(ii)

a maximum peak e.i.r.p. no greater than -25.0 dBm or the equivalent transmission level;

(f)

at frequencies above 10.6 GHz when measured in any direction have:

(i)

a maximum mean e.i.r.p. density no greater than -85.0 dBm/MHz; and

(ii)

a maximum peak e.i.r.p. no greater than -45.0 dBm or the equivalent transmission level.

(5)

The equipment only emits transmissions at frequencies between 3.4 GHz and up to and including 4.8 GHz which:

(a)

at frequencies between:

(i)

3.4 GHz and up to and including 3.8 GHz when measured in any direction have:

(aa)

a maximum mean e.i.r.p. density no greater than -85.0 dBm/MHz; and

(bb)

a maximum peak e.i.r.p. no greater than -45.0 dBm or the equivalent transmission level;

(ii)

3.8 GHz and up to and including 4.2 GHz when measured in any direction have:

(aa)

a maximum mean e.i.r.p. density no greater than -70.0 dBm/MHz; and

(bb)

a maximum peak e.i.r.p. no greater than -30.0 dBm or the equivalent transmission level;

(iii)

4.2 GHz and up to and including 4.8 GHz when measured in any direction have:

(aa)

a maximum mean e.i.r.p. density no greater than -41.3 dBm/MHz; and

(bb)

a maximum peak e.i.r.p. no greater than 0.0 dBm or the equivalent transmission level; or

(b)

at frequencies between 3.4 GHz and up to and including 4.8 GHz when measured in any direction have a maximum mean e.i.r.p. density no greater than -41.3 dBm/MHz provided a low duty cycle applies such that:

(i)

the duration of each transmission does not exceed five milliseconds;

(ii)

the sum of all transmitted signals in any second is less than 5% of that second;

(iii)

the sum of all transmitted signals in any hour is less than 0.5% of that hour; and

(iv)

the maximum peak e.i.r.p. is no greater than 0.0 dBm or the equivalent transmission level.
