2. United Frame Format
All the receivers in the 15.4 network, will fist check the first 3bits of the received MAC frames, this field is defined as Frame Type field, then analyze the received MAC frames for different formats setting, according to the different value of this field.

3. Common MAC Frame Format
When the value of Frame Type field is between 000~011, the MAC frames will use the united MHR as follow:
Frame Control field
Frame Version subfield: 00 indicates compatible with , 01 indicates compatible with , 10 indicates compatible with the new frame version we defined here.
Change the reserved bit 7-9 to Network Type subfield, indicating the MAC frame used for which network. This subfield is only meaningful when the Frame Version subfield is set to 0x10.
