Slide 4

Technical Issues:– A new device creating a Network does a scan of the environment

and get to know about the existing PAN in the network.

– Based on the scan results the new device selects a Unique PAN ID to create a new Personal Area Network.

– In case of an existing network which is using RIT, will not be able to communicate any information about its PAN as the receiver will be OFF most of the time.

– In such case there is a possibility that the new device may create the new Personal Area Network using a pre-existing PAN ID.

Slide 5

Proposed Solution:– Introduction of a new type of PAN ID

• Extended PAN ID (64 bit)

– If the extended PAN ID is selected, the PAN ID field will be of 64 bit length and it will contain the Extended address of the PAN coordinator.

– This will make sure that no two PAN in the network have same PAN ID even if we have a PAN consists of sleeping devices.

– 0xFFFFFFFFFFFFFFFF: Broadcast extended PAN Identifier in case the extended PAN ID Mode is selected.

– Following slides explains the changes required in the specification

Proposed Change in the specification

Frame Format changes:– Page 112, Line number 16-29

– Chapter “7.2 General MAC frame format”– Change the “Figure 86 – General MAC Frame Format” to support the 8

Octets Destination and Source PAN Identifier.

Slide 7 Amarjeet Kumar, Procubed

Proposed Change in the specification

Frame Control Field change:– Page 113, Line number 1-9– Chapter “7.2.1 Frame Control field”– Change the “Figure 87 – Format of the Frame Control Field” to use the 7th bit

(currently reserved) as PAN ID Mode.– The PAN ID mode should indicate the type (normal or Extended) of PAN ID used.

Slide 8 Amarjeet Kumar, Procubed

Proposed Change in the specification

PAN ID Mode description:– Insert the below description in Page 114, Line number 3

7.2.1.6 PAN ID Mode

The PAN ID Mode field shall be set to NORMAL_PANID if the device is sending the frame with 2 Octets Normal PAN Identifier and it should be set to EXTENDED_PANID if the device is sending the frame with 8 Octets Extended PAN Identifier.

Table 7 – values of PAN ID Mode Field

– The following chapter number will need to be reassigned automatically after insertion of above.

Proposed Change in the specification

Changes in other places with respect to PAN ID:– In Page 116, Line number 40

A value of 0xffff or 0xffffffffffffffff in this field shall represent the broadcast PAN ID, which

Proposed Change in the specification

Modification in the API’s:– All API’s and structures which uses the PANID as one of the parameter

needs to add an additional field “PAN ID Mode”.• MLME-ASSOCIATE.request()

• MLME-DISASSOCIATE.request()

• MLME-DISASSOCIATE.confirm
