Abstract: Communicating wireless devices collaborate and utilize waveforms to enable secure channel estimation. To protect against a repetitive replay attack, some embodiments include Single Carrier Physical Layer (SC-PHY) waveforms and/or interpolated OFDM waveforms that do not include a repeatable or predictable structure. The waveforms are transmitted in ranging packet structures that are compatible with legacy 802.11 technologies that do not utilize secure channel estimation. The ranging packets are received in combination with the information previously exchanged to enable the receiving wireless system to securely determine a channel estimate (e.g., determine a channel estimate without an interloper transmission that is not an authentic first arrival path in a multi-path channel between the wireless systems). Thus, one or both of the wireless systems can estimate the distance between them (or range). Devices utilizing legacy 802.11 technologies may receive the ranging packet structures and determine durations for deferring access to the channel.

Abstract: In some implementations, the device may include exiting a shelf-life mode and turning on a peer-to-peer wireless protocol in response to detecting a power source. A device identifier can be provided to a host device via the peer-to-peer wireless protocol. A connection ticket authorizing the electronic device to connect to a wide area network can be received from the host device via the peer-to-peer wireless protocol. The connection ticket can be being generated by a server system using a private key. The connection ticket may include the device identifier associated with the electronic device. A connection to a wide area network can be requested from an access point using a network wireless protocol. A software update can be performed over the wide area network via the access point.
