Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, are configured to spread a first frame of data using a first spreading code to create a spread first frame and to spread a second frame of data using the first spreading code to create a spread second frame. A delay generator generates a first transmission delay and a second transmission delay. A transmitter starts to transmit the first spread frame on a first frame boundary delayed by the first transmission delay and starts to transmit the second spread frame on a second frame boundary delayed by the second transmission delay. A receiver starts to receive a third spread frame on a third frame boundary delayed by the first transmission delay and starts to receive a fourth spread frame on a fourth frame boundary delayed by the second transmission delay.

Synchronized access point transmissions with random timing

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.

Downlink communication with multiple acknowledgements

This disclosure relates to method, device and system for compensating for information not received in a communication system. An encoded signal is created from a source signal using a forward error correction technique. A first predetermined part of the encoded signal is transmitted.

One or more antennae are selected to transmit the spread data stream based upon the first signal strength and the second signal strength. The data stream is transmitted using the one or more selected antennae.

Light monitoring system using a random phase multiple access system

This disclosure relates to method, device and system for selecting a device for communication in a communication system. A node receives a spread signal from a first transmitter and a second transmitter. The node despreads the spread signal with a first spreading code into a first frame and determines a first receive signal strength indicator (RSSI) from the first frame. The node despreads the spread signal with a second spreading code into a second frame and determines a second RSSI from the second frame. The node selects an access point based in part on the first RSSI and the second RSSI. The node transmits an uplink signal to the access point based on a slot start time and a random timing offset. The node transmits while a portion of a second signal is transmitted from a second node such that both the uplink signal and the second signal are received.
