Persistent mesh for isolated mobile and temporal networking

A multi-part mesh network comprising:

• a first mesh network and a second mesh network wherein each mesh network comprises:
• a) at least two structured mesh nodes;
• wherein each structured mesh node comprises at least a connectivity logic;
• an uplink radio operating on an uplink frequency and a downlink radio operating on a downlink frequency;
• wherein the connectivity logic determines whether each structured mesh node connects with an external network or another node using its uplink radio and client devices or other mesh nodes connect to each node using each node's downlink radio;
• wherein the structured mesh network functions in two configurations selected depending on whether a connection to an external network is present;
• b) in the first connected configuration the structured mesh network includes at least one structured mesh node's uplink radio comprises a connection to an external network;
• and
• c) in the second isolated configuration none of the structured mesh nodes' uplink radio comprises a connection to an external network, and one of the structured mesh nodes acts as an isolated network root of the isolated configuration and all remaining nodes' connect to the isolated network root node as isolated root children nodes forming a tree-like configuration;
• wherein a first set of frequencies, the first network frequencies, is used by the first network for communications between the nodes of the first network;
• a second set of frequencies, the common frequencies, is used for communications between the two networks;
• and a third set of frequencies, the second network frequencies, is used for communications between the nodes of the second network;
• wherein each network is in the isolated configuration;
• and
• wherein initially no communication between the first network and the second network is occurring.
