  • Patent number: 11044009
    Abstract: Embodiments include methods and apparatus for wireless network communication between a device that operates a radio in compliance with a wireless communication standard and another device that may not be capable of complying with the wireless communication standard. In an embodiment a sender of a wireless standard compliant message modulates backchannel data on a wireless standard compliant message. The wireless standard compliant message may be addressed to an IP address of a compliant device. However the compliant message may have no meaning for the addressee. A noncompliant device within wireless range of the compliant message receives the message and demodulates the backchannel information. The noncompliant device this does not require a wireless standard radio to be on in order to receive messages and can operate at very low power.

  • Patent number: 10420072
    Abstract: Embodiments include methods and apparatus for wireless network communication between a device that operates a radio in compliance with a wireless communication standard and another device that may not be capable of complying with the wireless communication standard. In an embodiment the non-complaint device is a receiver only. Information is broadcast or advertised or otherwise transmitted by the compliant device according to the protocol and embodiments encode information on top of the protocol for decoding by the receiving device, which does not decode the protocol.

  • Publication number: 20050262241
    Abstract: Admission to a computer network is provided by having a network device listen to a communication channel communicatively coupling two or more components of the computer network. In some cases, the network device may then transmit a connection request to a controller of the computer network within a designated time slot of the communication channel. In other cases, the connection request may be transmitted without requiring the network device to be polled. The connection request may be confirmed by transmitting the connection request from the controller to network device periodically, until a response from the first network device is received by the controller. Upon confirmation, the controller may send to the network device, a connection agreements package, which includes information regarding time slots within the communication channel to be used by the controller for transmitting information to the first network device.
