Frequency Assignment for Trunked Radio Networks (PMR / TETRA)
German trunked radio network operator require frequency licences to operate their radio stations (telecommunication act (§ 55 paragraph 1 und 3) The regulatory authority performs the frequency coordination process for all frequencies and for all radio sites. If all requirements are met a frequency license is issued. Changes of site or radio parameters trigger a new licence request.
It should be noted that many frequency licenses where temporary only and expired 31.12.2015 already.
PreHCM supports you during processing and improving your frequency request processes at a fixed price. This will begin with making a professional request documentation according to administrative regulation (VVBüfu) and go up to consulting and support.
- HCM check
- HCM optimization
- HCM propagation footprint (antenna radiation pattern) and optimization
Frequency Assignment for TETRA Systems deployed at Offshore Wind Farms
The German implementing directive of the Ministry of Transport demands („Seeraumbeobachtung Offshore-Windparks“) that operator of offshore wind farms need a frequency license. The Regulatory Authority coordinates all frequencies for offshore areas and assigns each single frequency for a site location. Changing radio parameters trigger a new licence request.
Frequency assignment in marine area require a different frequency coordination process. Radio sites located in an exclusive economic zone (AWZ) are administered by BNetzA. BNetzA also does coordination with neighbouring countries.
Limitations to Trunked Radio Systems due to Border Proximity
Limits set by HCM agreement in border areas can put challenges on Trunked Radio sites. In worst case scenarios no economic justifiable operation won’t be possible. Respecting these obligations is monitored by national telecommunication regulatory Aauthorities – in Germany BNetzA.
The HCM Agreement provides a harmonized calculation method to predict interfering field strength levels. The calculation result depends on several radio parameters. Regulatory restrictions can make optimal radio coverage impractical.
Radio Site Optimization can help in difficult Cases
If field strength of radio sites exceed limits in border areas or at radio monitoring locations of BNetzA then these sites they don’t comply with regulations and won’t receive a frequency license. Complex changes of these sites are necessary or even moving of sites in bad cases can be required. Radio site tuning based on HCM calculations can fix the problem and save operators from additional cost.
PreHCM acts as your representative and manages the complete process for a radio site or even your entire network. Our goal is to successfully request the frequency licence with proven HCM compliance.
