Traduction de «Frequency-tuning-range limit » (Anglais → Français) :

Notwithstanding paragraph (a), in the Canadian waters of a roadstead, harbour, river, lake or inland waterway, the upper limit of the frequency range referred to in that paragraph may be expanded to be within the range of 180-2/100 Hz (± 1 per cent).

5.19 (1) If a device that is capable of producing and emitting energy in the form of electromagnetic waves or acoustical waves is used on board an aircraft, the radiation to which an employee is exposed shall not exceed the limits recommended in Chapter 2 of Safety Code 6, Limits of Human Exposure to Radiofrequency Electromagnetic Fields in the Frequency Range from 3 kHz to 300 GHz published by the Department of Health.

In the specific frequency bands covered by this Decision, the combination of the harmonised short-range devices category and the technical usage conditions (frequency band, transmit power limit/field strength limit/power density limit, additional parameters and other usage restrictions) establishes a harmonised sharing environment in such a way as to allow short-range devices to share the use of spectrum with each other on a non-exclusive basis, regardless of the purpose of such use.

It is important to note that Safety Code 6 sets forth maximum human exposure limits for a range of frequencies in the RF spectrum and not device emission limits.

With regard to (b), Safety Code 6 sets forth human exposure limits for electromagnetic fields in the frequency range 3 kHz to 300 GHz.

On the other hand, it's perhaps so modest that it does raise some sovereignty protection implications, which the committee might like to address. In terms of possible measures we could take, I'll run through these very fast: additional land, sea, and air deployments from southern Canada; improved multi-agency data sharing and analysis; the creation of a modest, and I stress modest, northern training centre; the retention and upgrading of the Arcturus, Arctic sovereignty aircraft, or what was nominally supposed to be an Arctic sovereignty aircraft but is now scheduled to be disposed of; acquire a supplement to the Twin Otter aircraft currently stationed in Yellowknife; acquire and we're looking at naval options an ice-capable seabed ope ...[+++]rations vessel; explore a full range of space-based sensors, unmanned aerial vehicles, and subsurface surveillance systems, northern terrain vehicles; explore the utility of high-frequency surface wave radar in the north I believe Dr. Leggatt spoke to you about that and acknowledged that it had some potential utility, but there were limitations; and, in the longer term, continue to explore the potential for installing air-independent propulsion power plants on the four recently acquired submarines.
