Summary

One of the tasks in writing a good standard is to choose a set of terminology and to consistently use it. The 802.15.3 standard differentiates among four different types of piconets that can be formed: independent, parent, child, and neighbor. Timing in the piconet is based on the superframe. The superframe begins with the first symbol in the PHY preamble of the beacon and ends superframe duration later. The DEVs are required to set their timers to zero at the start of the PHY preamble of the beacon. The PNC is key to the operation of the piconet. The PNC controls membership in the piconet using association, disassociation, and secure membership. A key part of any networking standard is the ability to split data up for transmission and the reassembly of the data at the receiver. Fragmentation can be done at any layer in the protocol stack.
