Private Business Radio (PBR)
PBR is a category of private mobile radio (PMR) and can be divided into different user groups, some of which are represented by umbrella organisations and interest groups.
PBR user groups, defined by task, includetrading enterprises, craft enterprises, commercial enterprises, authorities, industrial enterprises, (passenger and goods) transport companies, taxi and car hire companies, public and local utility companies, rescue services, social services, and medical professions.
PBR networks usually have a base station (headquarters) and a number of (in-vehicle and/or portable) mobile stations, and a typical coverage range of between 10 km and 15 km. The service area of PBR networks without a base station is taken to be a particular geographic region, for example "Frankfurt city".
Frequencies in the following bands have been designated for PBR:
- 34.75-34.95 MHz
- 68.00-87.50 MHz
- 146.00-174.00 MHz
- 443.00-444.00 MHz
- 455.00-460.00 MHz
- 465.00-470.00 MHz
Given the limited spectrum resources available, frequencies are generally assigned for shared use.
Radio frequencies for PBR networks are normally assigned by the Federal Network Agency's regional office responsible for the area of operation. The frequency assignment specifies the parameters related to the intended use, such as location, channel bandwidth, modulation, transmitter power, antenna height and antenna type, but may also lay down usage restrictions designed to ensure compatibility with other frequency users.
Interconnection with Public Telecommunications Networks
PBR networks may under certain conditions be connected to public telecoms networks for the purposes of speech transmission, subject to special prior approval from the Federal Network Agency.
Advice from the Federal Network Agency
Anyone planning a PBR network is recommended to seek advice from their nearest regional office, in particular before buying their radio equipment, in order to avoid misinvestments. For further information, please contact your nearest regional office.
