Therefore the PHY header has as size of 40 bit, including CRC.
For additional protection, the header in encoded using a [8,4] Hamming code, which can reliably correct single-bit errors and detect double-bit errors in every block of four bits.

The encoded data is always modulated using QPSK.

=== Burst Transmission
Burst transmission allows the transmitter to send multiple packets in quick succession.
Packets are transmitted in bursts which combine multiple packets in a contiguous transmission.
A burst consists of the following elements:
