Beacon frames Sample Clauses
Beacon frames. MAC Header field settings for beacon frames are described in Table 52. Beacon frames are also referred to as beacons throughout this specification. The beacon frame payload is illustrated in Figure 17. The information elements (IEs) that may be included in a beacon frame are listed in Table 61 in 7.8. IEs are included in order of increasing Element ID, except for ASIEs and DRP-C IEs. ASIEs do not appear prior to any IE with Element ID zero through seven, but may appear anywhere after those IEs. If a DRP-C IE is used to provide context for a reservation, then that DRP-C IE must immediately precede the first DRP IE describing that reservation. DRP IEs that have the same Target DevAddr and Stream Index must be adjacent to each other in the beacon. The Beacon Parameters field is illustrated in Figure 18. The Device Identifier field is set to the EUI-48 [B7] of the device sending the beacon. A device may use a NULL EUI-48 value (all bits set to one) to indicate it does not have a unique EUI-48 value. The EUI is a sequence of 6 octets, labeled as eui[0] through eui[5]. The first three octets (eui[0] through eui[2]) are the manufacturer’s OUI, and the last three octets (eui[3] through eui[5]) are the manufacturer-selected extension identifier. Octets of the EUI are passed to the PHY SAP in ascending index-value order. The Beacon Slot Number field is set to the number of the beacon slot where the beacon is sent within the beacon period (BP), in the range of [0, mMaxBPLength-1], except in beacons sent in signaling slots. In signaling slots it is set to the number of the device’s non-signaling beacon slot. The Device Control field is illustrated in Figure 19.
