Abstract

A system of aggregating messages utilizing at least one device transmitting at least one short communication message wherein said short communication message comprises a terse command or status message; at least one network router comprising a means of receiving the short communication messages; wherein said means receives said short communication message without interrupting other communications; and an uplink from the at least one router to an external ip-based network wherein said router aggregates said short communication messages and forwards the aggregated messages via the uplink to the external ip-based network wherein said external ip-based network comprises a tree-based logical network comprising wireless nodes.

Claims (9)

1. A tree-shaped mesh network comprising:

a mesh of wireless nodes forming a tree shaped network with one root node having a connection to an external network; chirp clients; and wireless network clients;

wherein chirp clients comprise low cost chirp devices wherein said low cost chirp devices transmit short duration messages wherein transmission of said short duration messages are scheduled at random intervals;

wherein at least one wireless node of the mesh of wireless nodes is a designated chirp-aware node and said chirp-aware node further comprises a bridge between the short duration messages and IP based devices wherein said bridge includes a wireless receiver to receive the short duration messages and is connected to said external network;

wherein all remaining wireless nodes of the mesh of wireless nodes disregard the short duration messages as random and transient noise by adaptively filtering out the short duration messages using Automatic Gain Control, Error correction or noise cancellation, wherein the short duration messages are sufficiently short in duration so that said adaptive filtering by said all remaining wireless nodes disregards the short duration messages as random and transient noise;

wherein each wireless node further comprises two logical radios and a service radio wherein each wireless node uplink and downlink operates on distinct non-conflicting frequencies; and

wherein said wireless network clients communicate with said wireless nodes using said service radios.

2. The tree-shaped mesh network of claim 1 wherein the designated chirp-aware node is at an edge of the tree-shaped mesh network and wherein said chirp-aware node containerizes the short duration messages into containerized packets.

3. The tree-shaped mesh network of claim 2 wherein the designated chirp-aware node assigns a target to the containerized packets.
