Above 10 GHz, the power density shall be averaged over any 68/f -minute period (where f is the frequency in GHz) to compensate for progressively shorter penetration depth, as the frequency increases.

(21) In addition to a timely and pro-competitive freeing up of the 880-915 MHz and 925-960 MHz frequency bands (the ‘900 MHz band’) in accordance with Directive 2009/114/EC of the European Parliament and of the Council , the 790–862 MHz band (the ‘800 MHz band’) can be used in an optimal way for the coverage of large areas by wireless broadband services.

(4a) The future use of the 900 MHz band and in particular the question of how long GSM will remain the reference technology for technical coexistence in this band is a question of strategic importance for the internal market that should be examined together with other issues of the Community's wireless access policy in the future radio spectrum policy programmes, to be adopted in accordance with Directive 2002/21/EC of the European Parliament and of the Council of 7 March 2002 on a common regulatory framework for electronic communications networks and services (Framework Directive) as amended.

Recognising that this technology can affect a range of species and degrade marine habitat worldwide, what research is planned in Europe to study the impact of LFA and other high-intensity sonars on marine life, and the cumulative and synergistic impact of several nations simultaneously deploying these technologies?

The selection of frequencies for Galileo's PRS signal is perfectly justifiable in technical terms, however, as this is the frequency spectrum which offers the best performance in peacetime, particularly in terms of resistance and robustness, the best cost/benefit ratio, and the best guarantee of continuity and integrity.
