A method and corresponding system is disclosed for use in a Networked Lighting Control System whereby communication costs (e.g. costs associated with LTE technologies), variable electric rates and traffic models are analyzed to maximize cost savings. In one example, the system consists of receiving cellular usage rates, electric usage rates, and generated traffic models or statistics to manage transmission and broadcast of usage rates to lighting poles. An apparatus associated with the lighting pole can then use this information to determine frequency of sending lighting commands to nearby poles.

Lighting system optimized for cost reduction

A method and apparatus for adjusting the transmission power level or transmission data rate between a plurality of stations located within the coverage area of a basic service set (BSS) or in an independent basic service set (IBSS) in a wireless local area network (WLAN). The receiving station extracts a transmission data rate from an incoming signal, determines a signal-to-noise ratio (SNR) for the incoming signal, and then calculates noise margin information based on a difference between the SNR of the incoming signal and a minimum SNRfor the extracted data rate. The noise margin is then transmitted back to the original transmitting station and using the noise margin information, the transmit power level and/or the transmission rate of this station may be adjusted accordingly.
