The benefits of BOS Digital Radio Network
BOS digital radio network offers enormous benefits to the security authorities and rescue forces.
BOS digital radio network meets the key operational and tactical requirements for a state-of-the-art communication between public security and safety services and features a great number of technical performance criteria which help operational forces to accomplish their mission.
Currently, the authorities and organisations with security and safety tasks operate and use separate analogue radio networks that are independent of each other. This analogue radio technology is meanwhile obsolete and is being replaced by BOS digital radio network which is currently one of the Federal Government's major technological modernization projects.
The following comparison highlights the key benefits of BOS digital radio network as compared to analogue radio technology:
A single network for all security authorities and organisations
- All authorities and organisations with security and safety tasks use a single, nationwide voice and data communications system. The inter-agency communication allows for new forms of cooperation and offers substantial advantages when it comes to organizing and controlling operations.
- With analogue radio, each authority and organisation with security and safety tasks used their own network with its own radio channels and a limited geographic reach.
Security against interception
- In terms of security functions, the TETRA-standard already provides for radio interface encryption which protects the transmission section between the mobile terminal equipment and the base station but does not provide any protection for the underlying network infrastructure. For this reason radio communications in the BOS digital radio network are additionally encrypted by means of a special software (so-called end-to-end encryption). This solution puts Germany into a leading position, also internationally.
- Analogue radio communications are not secure against interception.
- Since each digital radio set has its own address, it is possible to have separate one-to-one radio communications with individual users without other users listening in on the communication.
- With analogue radio communications it is technically not possible to restrict the number of participants. All users of a given radio channel can listen in on all radio communications (open radio channel).
- Apart from the communication within a static user group it is also possible - e. g. in case of a large-scale emergency - to connect participants from different groups, and even from various public safety and security services and across long distances.
- With analogue radio it is not possible to connect different user groups as and when operationally required.
- Radio channels are occupied only as long as they are actually being used.
- With analogue radio communications, each channel permanently occupies a frequency of its own. Even if there is no voice communication going on, this frequency is not available to other users. For this reasons, there is a regular overload of radio frequency channels in case of large-scale emergencies.
Improved voice quality and audibility
- Digital radio technology offers a clearly improved voice quality as ambient noise is suppressed or filtered out.
- With analogue radio technology, the voice and reception quality tends to be poor ("white noise").
- In line with the needs of the authorities and organisations with security and safety tasks, the BOS digital radio network provides a secure, highly available voice communication plus a narrowband data communication which makes it possible to alert the police, for example.
- With analogue radio systems, the data transmission capabilities are very limited.
- With a digital radio network, it is possible to place calls from the radio network into the public telephone network.
- This functionality does not exist with analogue radio networks.
Emergency call button
- All digital radio sets are equipped with an emergency call button. A push on the emergency call button sets up a voice communication which takes priority over all other communications. Thus, messages can be immediately passed on to the command and control centre or other emergency call centres. If the radio sets also have a GPS-receiver, the person in distress can also transmit his or her exact geographic location.
- Analogue radio sets do not feature an emergency call button.
