Abstract: An apparatus, method and computer readable medium for special thermal density reduction by antenna thinning. A system comprises N transmit/receive (TX/RX) chains, where each TX/RX chain comprises an RFFE and each RFFE comprises one or more thermal sensors configured to measure heat in the RFFE. An antenna array coupled to the plurality of TX/RX chains. A codebook that comprises a plurality of code words configured to respond to real-time heat measurements from the thermal sensors in each TX/RX chain is configured to switch off selected TX/RX chains to reduce thermal density at the antenna array while maintaining M RFFEs switched on, where M

Abstract: A method can include receiving, from communicatively coupled mesh nodes of the mesh distribution network, data indicating whether respective mesh nodes of the mesh nodes are acting as gateways and an amount of traffic being served by the mesh nodes, determining, based on the received data, a first mesh node of the mesh nodes to put into an inactive state, and providing a communication to the first mesh node that causes the first mesh node to enter the inactive state.
