TinyOS has two 802.15.4 frame formats. The first format, the T-Frame, is for TinyOS networks which do not share their channel with other wireless -networking archtiectures. This frame format assumes that TinyOS can use +networking architectures. This frame format assumes that TinyOS can use every bit of the packet and does not need to state that it is a TinyOS packet.
