Integer 0–5 The maximum number of backoffs the 0 macMaxCSMABackoffs LLDN simplified CSMA-CA algorithm will attempt before declaring a channel access failure. LLDN Security LLDN cannot be secured in this standard. LLDN uses 8-bit addresses (simple addresses). Any mode using simple addresses including LLDN shall not use security. Data frames Type b001) and MAC Command frames (Frame Type b011) may be used within an LLDN. In this case, the Security Enabled bit of the Frame Control field of these frames shall be set to zero (no security enabled). PHY considerations The LLDN specification has been developed for the 2450 MHz O-QPSK PHY. The LLDN specification is PHY-independent, in principle. For instance, it can be used with the HRP UWB PHY. However, the use of several PHYs of this standard with LLDN is not advisable, for instance, PHYs targetting a completely different application case than LLDN. There is no requirement that every PHY of this standard has to support LLDN.
