Self-organizing communications network nodes and systems

A wearable communications node, comprising:

• an apparel item in the form of a backpack attachment that comprises:
• a panel;
• a first arm extending from the panel;
• a second arm extending from the panel opposite the first arm;
• an antenna element affixed to the first arm or the second arm;
• an A/V hub affixed proximate to the first arm or the second arm;
• a communications device;
• a battery;
• a control circuit communicatively coupled to the antenna element, the A/V hub,
• the communications device, and the battery;
• wherein
• the backpack attachment is configured to demountably attach to a backpack via one or more of the panel, the first arm, and the second arm;
• the A/V hub
• is affixed to at least one of the first arm and second arm;
• demountably and communicatively couples to an audio/video source;
• the control circuit is configured to establish, via the communications device, a self-organizing local area network (“LAN”) with a plurality of computing devices that each connects directly, dynamically, and non-hierarchically to the LAN;
• the antenna element comprises:
• a conductive composition comprising:
• fully exfoliated single sheets of graphene;
• a polymer;
• the fully exfoliated single sheets of graphene
• form a three-dimensional percolated network within the polymer;
• and
• are separated on a nanoscale within the polymer.
