Abstract: An apparatus includes a radio frequency (RF) receiver to receive packets. The RF receiver includes first and second synchronization field detectors (SFDs). The first and second SFDs detect synchronization headers generated using first and second physical layer (PHY) modes, respectively.

Abstract: A system having a locator device and a plurality of tag devices is disclosed. The locator device comprises an antenna array allowing it to determine an angle of arrival for incoming signals from each of the plurality of tag devices. The system also defines a sequence of time slots, where each time slot has a specific function. The sequence may start with a locator time slot, where the locator device transmits a packet that informs all of the tag devices that this is the start of the sequence. A sync slot follows the locator time slot, where new tag devices may transmit a sync request to the locator device. Upon receipt of a sync request, the locator device assigns the new tag device a tag slot. Following the sync slot are a plurality of tag slots, where each tag device transmits an AoA packet during its assigned tag slot.

Abstract: A novel system and method for remotely debugging a network device is disclosed. A debug system is used to transmit debug commands over a network to the network device. The network device interprets the debug commands. The processing unit on the network device includes a special debugging mode where it is able to perform special debug operations. This special debugging mode operates at a priority that is lower than that of the network interface so that the network device can still receive network packets while being debugged. The network device also has the ability to generate responses to the debug commands in some embodiments. The concept of wireless debugging can also be applied to multi-core processors as well.
