MAC sublayer service specification
- MAC sublayer constants
- MAC PIB attributes
- MAC PIB security attributes
- Elements of ACL entry desriptor
Constants have a general prefix of "a"
Attributes have a general prefix of "mac"
The MAC sublayer provides two services, accessed through two SAPs:
* The MAC data service, accessed through the MAC common part sublayer (MCPS
) data SAP(MCPS-SAP
* The MAC management service, accessed through the MLME-SAP
A hands on course focusing on the technical development of IEEE 802.15.4. The course moves from a fast paced introduction to wireless basics through to the technical specifics of 802.15.4 and then onto the building of an 802.15.4 application.
Who will benefit?
Technical staff requiring a grounding in 802.15.4 including application engineers.
None but the course is aimed at experienced technical staff.
By the end of the course delegates will be able to:
# Recognise the features and benefits of 802.15.4.
# Install and configure an 802.15.4 device.
# Describe the 802.15.4 standard and the Technologies it uses.
# Design 802.15.4 networks.
# Build 802.15.4 applications.
# Secure an 802.15.4 network.
