| | | DECT base | | | The DECT base offers the best prerequisites for low-effort and thus economical development of radio systems specially tailored to suit special customer wishes and application conditions using the worldwide recognised DECT (Digital Enhanced Cordless Telecommunication) telecommunication standard.
Technical features
A DECT radio system consists of at least one Fixed Part (FP) and one Portable Part (PP) and works with a frequency and time multiplex process in the frequency range between 1.88 and 1.90 GHz. 10 frequencies each with 1.728 MHz are available for the transmission. In each of these frequencies frames with a size of 10 ms are generated, which are in turn split up into 24 time slots. Half of these time slots are used for the transmission direction FP to PP and the other half for the transmission direction PP to FP. Because a DECT connection only needs one of these timeslot pairs, the system has up to 120 possible channels for this connection. All the rest can be used by other DECT systems for setting up connections. DECT thus enables a high density of connections in the smallest space that are independent of each other.
Technological advantages
The following advantages of DECT transmission technology can be used with the aid of the DECT base:
- Great anti-interference security
- High transmission power
- High data rates possible
- High eavesdropping and manipulation security
- Range of max. 300 m in open space
- Low power consumption
- Minimal construction size
Application examples
The DECT transmission technology opens up a multitude of new cordless data communication possibilities for the user.The following applications can be realised with software adaptations of the DECT base:
- Point-to-point data transmission via UART
- Speech transmission via PCM/ADPCM interface or Codec
- Display controls
- Measured value recording, measured value processing and data transmission
- Integration into existing systems with various interfaces possible
- Synchronous measured values recording (deviation ±10µs) at several stations and much more
