Report Itu-r Bs.1203-1* Digital Sound Broadcasting to Vehicular, Portable and Fixed Receivers Using Terrestrial Transmitters in the Uhf/vhf Bands

Propagation Effects Relating to Terrestrial Land Mobile Service in the Vhf and Uhf Bands

The ITU Radiocommunication Assembly, considering a) that there is a need for information on aspects of propagation likely to affect terrestrial land mobile services, recommends 1 that the information contained in Annex 1 be taken into account in the design and planning of such services. 1 Introduction This Recommendation provides information on various aspects of propagation which are likely to...

A path-specific propagation prediction method for point-to-area terrestrial services in the VHF and UHF bands

New Business Strategies and Marketing Opportunities Utilizing a Liberalized Spectrum Management Framework

The current global move to switch from analogue to digital terrestrial television has opened up an opportunity for the re-allocation of valuable spectrum resources in VHF/UHF frequencies. In one way, spectrum bands once used for analogue TV broadcasting will be completely cleared, leaving a space for deploying new licensed wireless services, and in another way, digital terrestrial television te...

Consideration of Interference Analysis for Wireless Systems in VHF/UHF Bands with Geographic Information

With the help of Rec. ITU-R P.1546 and geography information system, the interference analysis for the fixed wireless system and radar is presented based upon the frequencydistance rules with minimum coupling loss. To obtain the computational results, real geography information on the map was taken for the given area of 80x60[km] 2 , and field strength and path profile were illustrated for rada...

HF , VHF , and UHF Systems and Technology

A wide variety of unique systems and components inhabits the HF, VHF, and UHF bands. Many communication systems (ionospheric, meteor-burst, and troposcatter) provide beyond-line-of-sight coverage and operate independently of external infrastructure. Broadcasting and over-the-horizon radar also operate in these bands. Magnetic-resonance imaging uses HF/VHF signals to see the interior of a human ...
