CORRECTLY PLANNING OF DRM BROADCASTING NETWORKS

O.V. Varlamov, Moscow Technical University of Communications and Informatics, senior staff scientist, Ph.D.; vov@mtuci.ru.

The main questions of correct DRM network planning on LW and MW bands for daylight hours are considered. The reference point for the seasonal variations of the ground wave field strength was defined.
Defined maximum expected atmospheric radio noise field strength in different regions. In most parts of Russian Federation, they do not exceed the intrinsic noise of the receiver. For the calculation of the coverage area of the DRM system proposed to use ground-wave propagation curves, transformed to SNR curves, taking into account the atmospheric radio noise field strength the in the estimated region. It is shown that despite the increase in atmospheric noise field strength with decreasing frequency, the use of lower frequencies provides a substantially larger radius of coverage area.
A comparison of coverage areas in the AM and DRM modes are given.
The given examples of calculations are confirmed by experimental measurements.
Using DRM digital broadcasting on LW band can provide the most economical coverage of large areas with low population density, especially in the northern regions of Russia.
Key words: digital broadcasting, DRM, radio noise, field strength variation, coverage area, experimental measurements.

The article considersthe possibility ofputting the right to use radio frequency spectrum into civil circulation. Sufficient experience of other countries in this field as well as the existing native judicial practices allow to affirm the necessity to focus on the development of legal regime for the spectrum use meeting the demands of economic development of the country.
The article analyses the particularities of the legal regime for frequency spectrum, such as: the object of legal regime, defining the legal status of legal persons, defining the complex of regulatory, protective and procedural means. And developed proposals for updating the licensed activity.
Key words: radio frequency spectrum, natural resource, act of legislation, legal regime, civil turnover, right of use.

The article deals with problems arising during measurements of a radio-frequency spectrum occupancy in traditional conditions when requirements to accuracy of occupancy estimations are established in the form of limiting of maximum permissible relative or absolute errors. It is shown that for achieving of a reasonable compromise between equipment expenses and quality of obtained estimations, «floating» demands to errors should be imposed assuming that with increasing of an occupancy relative error will be more rigorous while allowing an insignificant increase of an absolute error of the evaluation. It is shown that at the lack of availability of a priori data on occupancy of analyzed channels, at a choice of an equipment operation mode it is necessary to be guided by obtaining of minimum 600 samples during integration interval of data accumulation for channels with lengthy signals, and not less than 1800 samples for radio channels with pulse signals.
Key words: radio-frequency spectrum, occupancy evaluation, measurement error.

Knowledge of the level of risk of threats to information security allows for the design, testing and operation of the network to make decisions to improve its information security by increasing protection against threats to which corresponds to the highest level of risk. This paper analyzes the mathematical model of evaluation threat levels adopted for multiple networks. The analysis is performed on the basis of ETSI, works domestic and foreign experts. All models are divided into those that are constructed using pre- calculate the risk of information security threats and without it. The possibility of using two of these models to assess the level of information security threats of fraud in the SIP signaling system for transmitting voice and data over IP.
