Methods, systems and instructions stored on computer-readable media for generating a first data stream and a second data stream. The first data stream is spread using a first gold code unique to a first tag. The second data stream is spread using a second gold code unique to a second tag. The spread first data stream and the spread second data stream are combined into a combined data stream. The combined data stream is transmitted to the first tag and the second tag.

Combined unique gold code transmissions

Methods, systems and instructions stored on computer-readable media for generating, at a first node, a plurality of data units. The plurality of data units are spread with a common pseudo-noise (PN) code that is used by a plurality of nodes, including the first node and a second node, that are in communication with an access point. A random timing offset is determined, and a first data unit is transmitted to the access point at a first time based upon a slot start time and the random timing offset. The first data unit is transmitted while at least a portion of a second signal is transmitted from the second node such that both the first data unit and the second signal are received by the access point. The second signal is transmitted at a second time based on the slot time and a second random timing offset.

Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, for receiving monitor data from a lighting equipment monitor. A data stream is created based upon the monitor data. A first signal strength of a signal from the access point received at a first antenna is measured.

Random timing offset determination

This disclosure relates to method, device and system for detecting errors in a communication system. A signal is received from a transmitter at a receiver wherein the signal includes a data portion and a result of a hash function. The hash function is computed in part from a transmitter identification code. The receiver determines if the result of the hash function matches both the data portion and the transmitter identification code. The receiver discards the signal if the result of the hash function does not match both the data portion and the transmitter identification code of the transmitter.
