Mobile-Satellite Services on national territory 1. This publication is … Ku-band (12–18 GHz) Used for satellite communications. Allocation of frequencies to satellite services s a complicated process which requires international coordination and planning. Satellite communications is now an indispensable part of the most major communications systems. Given the cross-border nature of services concerned, the advantages of pan-European coverage …

There is provided a method for improving an allocation of resources, i.e., frequency and power, to terrestrial services and satellite services that use a same frequency band. EU selection process On 27 February 2007, the European Commission adopted Decision No 2007/98/EC1, which aimed to promote European harmonisation of the use of 2 GHz frequency bands by systems providing Mobile-Satellite Services. To implement this frequency planning, the world is divided into three regions: Satellite Frequency Bands. Ka-band (26–40 GHz) Preface This handbook contains the table of frequency allocations in accordance with the Region 3 allocations under the Radio Regulations which are applicable to Hong Kong, the allocations which have been adopted by Hong Kong, as well as the band plans in use in Hong Kong. It also shows the internationally agreed spectrum allocations of the International Telecommunication Union (ITU). The United Kingdom Frequency Allocation Table (UKFAT) details the uses (referred to as 'allocations') to which various frequency bands are put to the UK. Framework 1.1. This is done as per the International Telecommunication Union (ITU). Frequency allocation (or spectrum allocation or spectrum management) is the allocation and regulation of the electromagnetic spectrum into radio frequency bands, which is normally done by governments in most countries. Last Updated: Saturday, 19-May-2018 15:41:17 MDT | By InetDaemon. To prevent interferance caused by multiple sites transmitting on the same frequencies, government agencies and standards organizations around the globe try to keep the … View Chart (276.83KB).

The higher frequency 6-8 GHz slot is for uplink signals to the satellite, and the lower frequency 4-6 GHz slot is used for downlink signals to earth receivers. Hong Kong Table of Frequency Allocations April 2020 Office of the Communications Authority . In Europe, Ku-band downlink is used from 10.7 GHz to 12.75 GHz for direct broadcast satellite services, such as Astra. 36 - 51.4 DBS = Direct Broadcast Satellite (Consumer direct-to-home Satellite TV) FSS = Fixed Satellite Service (Geostationary Comms Satellites for TV/Radio stations and networks) (Hz = Hertz, Mhz = Megahertz, Gh z= Gigahertz) There are a number of radio frequency ranges in use in satellite communications such as C, X, Ku, Ka and even EHG and V-band. The radio frequency spectrum is divided into frequency bands allocated to various radiocommunication services such as aeronautical, land mobile, meteorological and satellite communication services. US frequency allocations chart, 2016. It involves, for instance, television, radio, cell-phone, radar satellite broadcasting, etc., and even microwave ovens. Today, the world has become a very small place because of satellite communications allowing people with no access to physical connectivity to join roundtable discussions from thousands of miles For the direct broadcast service in the Ku band, the frequency used is 14/12 GHz.
