RES646 – 364 – r) that when a disaster occurs, the PPDR agencies and organizations are usually the first responders on the scene using their day-to-day communication systems and, additionally, other agencies and organizations may also become involved in disaster relief operations; s) that some countries in Region 1 have identified certain parts of the frequency range 694-791 MHz for broadband PPDR deployment; t) that some countries in Region 1 have identified certain parts of the frequency range 790-862 MHz for broadband PPDR deployment; u) the provisions contained in Nos. 5.266 and 5.267, and Resolution 205 (Rev.WRC-15); v) that Metaids and Metsat services operate on a globally harmonized basis in the frequency band 400.15-406 MHz; w) that the radio astronomy service operates on a primary basis in the frequency band 406.1-410 MHz and there may be PPDR operations adjacent to that frequency band, noting a) that many administrations will continue to use different frequency bands below 1 GHz for narrowband systems and applications supporting PPDR and may decide to use the same range for future PPDR systems; b) that some administrations also use certain frequency bands above 1 GHz for broadband PPDR applications; c) that applications requiring large coverage areas and providing good signal availability would generally be accommodated in lower frequency bands; d) that many administrations have made significant investments in PPDR systems; e) that flexibility allows disaster relief agencies and organizations to use current and future radiocommunications, so as to facilitate their humanitarian operations; f) that disasters and emergency events require response not only from PPDR agencies and organizations but also from humanitarian agencies and organizations; g) that broadband PPDR can be realized and deployed in the frequency bands identified for IMT; h) the benefits of cooperation between countries for the provision of effective and appropriate humanitarian assistance in case of disasters, particularly in view of the special operational requirements of such activities involving multinational response; i) the needs of countries, particularly the developing countries3, for cost-efficient communication equipment; j) that the use of technologies based on Internet protocols is well established, _______________ 3 Taking into account, for example, the latest version of the ITU-D Handbook on disaster relief.
