Abstract

This invention discloses a mesh network comprised of at least two dynamic mesh nodes, wherein the two dynamic mesh nodes comprise each a multiple radio access technology architecture, the multiple radio access technology architecture comprising: at least two radio access technologies for providing access to a core network, and an abstraction layer communicatively coupled to the at least two radio access technologies for receiving and converting data into protocol agnostic data, wherein the first and second dynamic mesh nodes are configured to: in response to a query regarding environmental conditions from a computing cloud component, send an environmental condition to the computing cloud component, receive an instruction from the computing cloud in response to the computing cloud component having processed the environmental condition, and change an operational parameter in response to the received instruction.

First claim

at least two different radio access technologies (RATs) for providing access to a core network and backhaul, and
an abstraction layer communicatively coupled to the at least two radio access technologies for receiving and converting data into protocol agnostic data,
wherein the first and second dynamic mesh nodes are configured to function dynamically switching between client and server or simultaneously acting a both client and server;
wherein the first and second dynamic mesh nodes are further configured to:
in response to a query regarding environmental conditions from a computing cloud component, send an environmental condition to the computing cloud component,
receive an instruction from the computing cloud in response to the computing cloud component having processed the environmental condition, and
change an operational parameter in response to the received instruction,
and wherein a dynamic multi-RAT mesh node uses a first RAT for access and a second RAT for backhaul and dynamically switches internally to using the second RAT for access and the first RAT for backhaul; and
wherein the mesh network is a heterogeneous mesh network and wherein a single routing table is used for heterogeneous nodes within the heterogeneous mesh network.

2. The mesh network of claim 1 , further comprising a self-organizing network, SON, module, a management layer, an application layer, or a control layer.
