% * + 5. The band 2.50-2.69 GHz (“the 2.5 GHz band”) was identified for International Mobile Telecommunications (“IMT”) at WRC-2000. The WRC-07 decision on agenda item 1.4 has further identified the band 2.30-2.40 GHz (“the 2.3 GHz band”) and band 790 – 806 MHz in Region 3, among other bands, for IMT including IMT-2000 and IMT-Advanced. 2.3 GHz band 6. Having consulted the RSAC at the 30th Meeting held in February 2006 and the public in May 2007, the Telecommunications Authority (“TA”) has decided in a statement1 broadband wireless access (the “BWA on Statement”) to allocate the 2.3 GHz band, as well as the 2.5 GHz band, to enable the provision of broadband wireless access services based on IMT standards in Hong Kong. 790-806MHz 7. Regarding the 790-806 MHz band, the IMT identification under the WRC-07 decision does not preclude the use of the band by any applications of the services to which they are allocated and does not establish priority in the Radio Regulations. 8. In the Spectrum Release Plan published by OFTA, 798-806 MHz had been identified for possible deployment of Digital Terrestrial Television (DTT), mobile TV in Hong Kong which is in line with the WRC-07 decision. 2055-2095 MHz 9. At present, the band 2055–2095 MHz is allocated for electronic news gathering and outside broadcast (“ENG/OB”) services on a temporary basis. The temporary allocation was based on the consideration that the band might be identified for IMT-2000 and IMT-Advanced when the band was opened up for ENG/OB applications in May 2007 (please see RSAC paper no. 4/2007 for details). According to the WRC-07 decision on agenda item 1.4, the band 2055-2095 MHz is not identified as a band for IMT. In the light of 1 TA Statement of 2 December 2007 entitled “Provisioning Radio Spectrum for Broadband Wireless Access Services”

the decision, the 2055-2095 MHz band would continue to be allocated temporarily for ENG/OB applications. % * +) 10. Agenda item 1.9 considers the sharing of the 2.5 GHz band between various space services and terrestrial services. According to the WRC-07 decision, the pdf limits of the space stations operating in this band will be reduced from -113 dBW/m2/MHz to -125 dBW/m2/MHz for 25-90o of angle arrival in order to protect the future development of the terrestrial services operating in the band, subject to a condition that the reduced pdf limits would not be applicable to the mobile satellite broadcasting networks which had been filed with ITU-R before this WRC-07 decision. 11. The mainland of China is planning to operate broadcasting satellite service (China Mobile Multimedia Broadcasting Service) in the 2635 – 2660 MHz band with its satellite footprint covering Hong Kong. This satellite broadcasting network was filed before WRC-07 and thus would not be subject to the reduced pdf limits requirement. In view of the potential interference between satellite broadcasting and terrestrial services, it may not be feasible to harness the 2635-2660 MHz band for other terrestrial services. 12. In addition, as explained in the BWA statement, this band is also a candidate band for mobile TV services in Hong Kong. In this connection, the TA will not allocate the 2635 – 2660 MHz band for the time being until a decision is made by the Government about the provision of mobile TV services in Hong Kong.
% * +, 13. At present, the band 135.7 – 137.8 kHz is allocated as fixed, maritime mobile and radionavigation service on a primary basis in Region 3. According to WRC-07 decision on agenda item 1.15, the band will also be allocated for the amateur service on a secondary basis in Region 3. Amateur stations operating in this band shall have a maximum radiated power of 1 W and shall not cause harmful interference to stations of the radionavigation service. In Hong Kong, there is no radionavigation station in the 135.7 – 137.8 kHz band. However, frequencies ranging from 3 kHz to 195 kHz are allocated for licence-exempt
3
telecommunications apparatus. At present, apparatus using the frequencies is mostly the anti-theft security system. 14. OFTA supports the WRC-07 decision on allocation of 135.7 – 137.8 kHz band for the amateur service. In the light of the large-scale deployment of anti-theft security systems in Hong Kong and the possible co-channel interference to these systems, OFTA would take a cautious approach in the frequency allocation. To this end, OFTA will initially allow the amateur to operate in this band under experimental permits. OFTA will assess the impact on the licence-exempt telecommunications apparatus during a trial period and subsequently decide to allocate the band for the amateur service by amending the Kong Kong Table of Frequency Allocation. ( - 15. OFTA has issued the Hong Kong Table of Frequency Allocations giving information on Region 3 allocation, Hong Kong allocation and band utilisation. The WRC 07 decisions will lead to revision to Region 3 allocation. Annex 2 gives a summary of revision of allocations in Region 3 including Hong Kong. To be in line with the timeframe for implementation of the WRC-07 decision, OFTA will update the Region 3 allocation accordingly and make public the revised Table in January 2009. OFTA will consult the RSAC in the future if the Hong Kong allocation and band plan are needed to be revised. . / 0 /(

Resolution 224 is revised for the above IMT identifications. These IMT identifications do not preclude the use of these bands by any application of the services to which they are allocated and do not establish priority in the Radio Regulations. Resolution [COM4/13] is added to invite ITU-R to conduct sharing studies for Regions 1 and 3 in the band 790-862 MHz between the mobile service and other services in order to protect the services to which the frequency band is currently allocated and to invite ITU-R to report the results of the studies for consideration by WRC-11. 3400-3600MHz 4 The band 3400-3600 is allocated to mobile service on a primary basis subject to agreement obtained under No. 9.21 with other administrations and is identified for IMT in some administrations.
