Provision 5.1.3
A digital entry in the Plan may also be notified
with characteristics different from those
appearing in the Plan, for transmissions in the
broadcasting service or in other primary
terrestrial services operating in conformity with
the Radio Regulations, provided that the peak
power density in any 4 kHz of the above-mentioned
notified assignments shall not exceed the
spectral power density in the same 4 kHz of the
digital entry in the Plan
4
Conformity to RR
operate in one of the frequency band allocated
for its type of service in accordance with the
Table of Frequency Allocations in Article 5 of
the Radio Regulations
5
Secondary service?
The notification and bring into use of services
with secondary status is treated under the
standard procedure of Article 11 of the Radio
Regulations

Band III GE06

Band IV V

8
Within spectrum envelope

• The MASK concept
• Does not exceed its spectrum right as a digital
  Plan entry
• Peak power density in any 4 kHz
• Radiated peak power

9
Conformity to the Plan entry

• To ensure that it does not cause more
  interference
• Different site location, effective heights
• Criteria in section II of the Annex 4 of the GE06
  Agreement
• Cut-off contours
• Buffer zones
• Compare field strengths at all the test points

10
No claim for more protection
The proposed notified assignment if successfully
recorded in the Master Register (MIFR) with a
favourable finding shall not claim more
protection than that afforded to the digital Plan
entry.

Some examples

• T-DAB using a DVB-T digital entry
• Mobile Television T-DMB using a T-DAB digital
  entry
• Fixed WiMAX
• IMT-2000 applications

12
How to notify

• eNotice GB1 (Circular Letter CR/262)
• t_pwr_dens Maximum power density (dB(W/Hz))
  averaged over the worst 4 kHz calculated for the
  maximum effective radiated power.
• t_emi_cls The class of emission of the
  assignment under treatment.
• t_bdwdth The necessary bandwidth of the system
  to be implemented (kHz)

13
Conclusions

• Flexible
• Responsive
• Long-lasting
