Claims

In a method for communicating through a multi-access communication network,
The method comprising: receiving a first signal from the first device, the first signal is spread using a first predetermined pseudo-noise (PN) code, the first signal 1 Transmitting after a first delay that includes a first random number related to the beginning of one slot , and wherein the first signal includes first payload data;
Receiving a second signal from a second device, wherein the second signal is spread using a second predetermined pseudo-noise (PN) code, and the second signal is Transmitted after a second delay including a second random number related to the beginning of the slot, and wherein the second signal includes second payload data, and Receiving at least a portion of a second signal while the first signal is received;
Selecting a first destination for the first payload data based on a first characteristic of the multi-access communication network;
Selecting a second destination for the second payload data based on a second characteristic of the multi-access communication network;
Transmitting the first payload data to the selected first destination;
With a method.

Determining whether the first destination and the second destination are the same;
Transmitting the second payload data to the selected first destination together with the first payload data if the first destination and the second destination are the same;
The method of claim 1, further comprising:

The method of claim 1, wherein the first characteristic of the multi-access communication network is a seed value assigned to a device.

Receiving a first communication signal via a broadcast channel including a first seed value;
Selecting a second seed value based on the received first communication signal;
The method of claim 1, further comprising:

5. The method of claim 4 , further comprising communicating a request to associate with a device based on the first seed value.

The method of claim 4 , further comprising communicating a request to associate with a device based on a power measurement of the received first communication signal.

The method of claim 1, further comprising receiving a transmission from an associated device.

The method of claim 7 , further comprising determining timing based on the received transmission.

The method of claim 7 , further comprising determining a transmit power level based on the received transmission.

The method of claim 4 , further comprising communicating a request to associate with the second device based on the one or more missed messages.

The method of claim 4 , further comprising transmitting a second communication signal over a broadcast channel having a selected second seed value.

The method of claim 1, further comprising transmitting a broadcast channel message that allows neighboring devices to participate in communications as peers.

The method of claim 1, further comprising determining frame timing or frequency drift from the received communication signal.

The method of claim 1, wherein the multi-access communication network comprises a mesh network.

The method of claim 14 , wherein the mesh network is based on an IEEE 802.11 standard set.

In an apparatus for communicating through a multi-access communication network,
A receiver configured to receive a first signal from a first device and receive a second signal from a second device, wherein the first signal is a first predetermined pseudo-noise. (PN) code is transmitted after a first delay including a first random number related to the beginning of a slot, and wherein the first signal is: Including first payload data;
The second signal is spread using a second predetermined pseudo-noise (PN) code, and the second signal includes a second delay including a second random number related to the beginning of the slot. And the second signal includes second payload data, and at least a part of the second signal is received by the first signal. A receiver that is received during
A transmitter,
Electrically coupled to the receiver and transmitter to command the reception of a first signal at the receiver, and the first payload from one or more devices based on characteristics of the multi-access communication network A controller operable to select a first destination for data and to command transmission of the first payload data to the first destination at the transmitter;
With a device.

The apparatus of claim 16 , wherein the characteristic of the multi-access communication network is a seed value assigned to the apparatus.

The controller further directs reception of the first communication signal via a broadcast channel of the communication network including the first seed value, and selects the second seed value based on the received first communication signal. and, and operable to direct the transmission of the second communication signals via a broadcast channel of the selected communication network with the second seed value, according to claim 16.
