* 18.1.1.1 Preamble field

* The Preamble field shall contain phyFSKPreambleLength multiples of the
* 16-bit sequence “0111 0111 0111 0111” for filtered 4FSK.
*
* We need to define this in order to be able to compute e.g. timeouts for the
* MAC layer. According to 9.3, phyFSKPreambleLength can be configured between
* 4 and 1000. We set it to 4. Attention: Once we use a long wake-up preamble,
* the timing parameters have to change accordingly. Will we use a shorter
* preamble for an ACK in this case???
