The
radio modem WZ DFM 500/430S is the logical extension of
our existing radio modem line. The maximum RF- output power of
500 mW as well as frequency synthesizer and signal strength
output are ideal for flexible and fast solutions. The modem
contains a synthesizer-controlled transceiver and a modem with
TLL interface. This makes bi-directional transmission (simplex)
possible.

Emergencies can be immediately transmitted via radio -
especially to protect the environment
- High transmission range due to high output power and GMSK
modulation
- Ideal for cellular networks in the private mobile radio sector
High
data rates and transmission range
GMSK modulation permits data rates up to 19200 baud. Thus, GMSK
modulation offers the optimal ratio between data rate and
RF-bandwidth. In comparison with other modulation methods, like
FFSK, GMSK modulation offers a higher transmission range and
better transmission security.
Interface with special functions
The WZ DFM 500/430S is controlled via TTL interface. The
interface offers some additional signals to optimise the
transmission characteristics.
Frequency synthesizer and signal strength output
The WZ DFM 500/430S uses a frequency synthesizer and
covers the frequencies from 433.100 MHz to 434.750 MHz.
Frequency switching is controlled by software, plug-in jumpers
or DIP switch (with controller WZ DFC). This feature offers
flexible and fast solutions.
The signal strength output permits an indication of the signal
strength at each site. By using this signal, the optimal
installation site can easily be found as well as topographical
data like illumination and coverage can be gained. A combination
of both features (frequency synthesizer and signal strength
output) enables the user to build up cellular networks for
professional applications in the private mobile radio sector. |
