Simple power over ethernet data transmission protocol

Simple power over ethernet data transmission protocol

The present invention relates to a simple data transmission protocol and a data receiving device (10, 10′, 10″, 10′″) for a power over Ethernet system (100′) using the simple data transmission protocol. The device (10, 10′, 10″, 10′″) comprises a port and a simple logic unit. The port is configured...

description The present invention relates to a simple data transmission protocol and a data receiving device (10, 10′, 10″, 10′″) for a power over Ethernet system (100′) using the simple data transmission protocol. The device (10, 10′, 10″, 10′″) comprises a port and a simple logic unit. The port is configured for receiving power and data transmitted to the device (10, 10′, 10″, 10′″) via an Ethernet connection (16′). The simple logic unit is configured to decode data encoded in a characteristic of one or more data packets received at the port. The data can be encoded in data packet length, data packet duration, number of data packets in a predetermined interval, and/or sequence of data packets. The simple data transmission protocol can reduce power consumption as in contrast to the Ethernet protocol MAC does not need to be decoded for information transfer. Hence only simple logic functions are required.
