摘要： Systems and methods for determining locations of wireless sensor nodes in a tree network architecture having mesh-based features are disclosed herein. In one embodiment, a system includes a hub having one or more processing units and RF circuitry for transmitting and receiving communications with sensor nodes to enable bi-directional communications. The one or more processing units of the hub execute instructions to configure the system with a tree architecture for communications between the hub and the sensor nodes, and to configure the system temporarily with a mesh-based architecture for determining location information for the sensor nodes.

摘要： The disclosed embodiments generally relate to techniques for processing signals received from multiple antennas. More specifically, the disclosed embodiments relate to a system that uses an integrated phase-shifting-and-combining circuit to process signals received from multiple antenna elements. This circuit applies a specified phase shift to the input signals, and combines the phase-shifted input signals to produce an output signal. In some embodiments, the integrated phase-shifting-and-combining circuit uses a current-steering mechanism to perform the phase-shifting-and-combining operations. This current-steering mechanism operates by converting the input signals into associated currents, and then steering each of the associated currents through multiple pathways which have different delays. Next, the currents from the multiple pathways for the associated currents are combined to produce the output signal. During this process, while steering each of the associated currents through multiple pathways to achieve different phase shifts, complementary impedance changes through the multiple pathways cause the aggregate impedance at the output to remain substantially constant.
