4.4. Modulation and transmission power
Modulation and transmission power play an important role in the transmission.
Modulation
Choose „HG“ (High Gain) for a robust, almost faultless transmission. It is especially suitable for
mobile applications without line-of-sight-connection between transmitter and receiver. This setting
makes use of the QPSK modulation, thereby considerably reducing transmission interferences
and errors. In return, the image quality is lower than HPQ.
If you select „HPQ“ (High Picture Quality) you operate with better picture quality. This settings
uses the 16QAM modulation, which transfers a higher data rate per second, yet consequently is
more susceptible to transmission interferences and errors.
Please note that setting 16QAM is only available for HPQ models!
Transmission power
This function can switch transmission power to an admitted value. For example a 100mW
transmitter in frequency band 5.8GHz transmission power can be reduced to 25mW (“middle“)
so that the European regulations regarding licence free 5.8GHz-ISM-band are fulfilled.
In case you intend to operate your system according to R&TTE directive and thus without
the need to get an approval of your local/national authorities, please take into account
that, the transmission power (EIRP) may not exceed the maximum threshold value
defined by your local/national authorities!
