Hcm Agreement


PreHCM International is the answer to these problems and the right solution for compliance with international cross-border agreements and national rules (such as authorisation procedures, radio surveillance sites, broadcasting coordination and coordination of mobile phone services for railways). To prevent wireless telecommunications systems (in the 29.7 MHz to 43.5 GHz frequency band) from causing harmful disruptions in border areas, 17 European countries have signed the HCM agreement to coordinate their allocation of frequencies. Representatives of seventeen national telecommunications authorities signed the HCM agreement for the coordination of the frequency band between 29.7 MHz and 43.5 GHz. The HCM agreement aims to prevent damaging disruptions and optimizes the use of resources in border areas. The national regulatory authorities (BNetzA in Germany) are responsible for monitoring compliance with international agreements. This allows operators to deviate from regulatory restrictions when operating agreements are entered into. The system treats all popular mobile network technologies such as GSM, UMTS, LTE, GSM-R, TETRA, PMR, Trunkfunk, analog radio and more. It offers simulation and prediction of frequency coordination up to individual radio cell level (based on the latest V7 version of HCM) and automation of the corresponding regulatory processes. Optimizations range from the coordination of individual cells (HCM/Wien-Muster model) to operator agreements. Operating agreements are subject to regulatory approval. In Germany, an administrative fiat (“Decision of the Chamber of Presidents of the Federal Network Agency for Electricity, Gas, Telecommunications, Posts and Railways of 28 January 2015 on the organisation and choice of procedure as well as on detailed provisions and rules, as well as the implementation of the frequency allocation procedure in the 700 MHz, 900 MHz, 1800 MHz and other frequencies in the 1452 – 1492 MHz range for access to the wireless telecommunications network; The decision in paragraph 55, paragraph 4, paragraph 5 and para. 10, 61, paragraph 1, paragraph 2, paragraph 3, paragraph 4, and para. 6, 132, paragraph 1 and par.

3 TKG” describes the concept of operating agreements. ITU and the EU are helping participating countries to establish a specific legal framework for the use and harmonization of radio spectrum in border areas, based on the cmM agreement. In the European Union (EU) and in particular in the countries participating in the HCM agreement, frequency coordination with neighbouring countries is based on the HCM algorithm (harmonized method of calculation) and depends on different radio parameters.
