First Claim
1. A system for providing a wireless asymmetric network architecture, comprising:
- a first hub having a wireless control device that is configured to control communications and power consumption in the wireless asymmetric network architecture; and
a first plurality of sensor nodes each having a wireless device with a transmitter and a receiver to enable bi-directional wireless communications with the wireless control device of the first hub in the wireless asymmetric network architecture, wherein the wireless control device is configured to determine a timing separation between a transmit window and a receive window of each wireless device of the first plurality of sensor nodes and to determine a timeslot definition signal that is defined with a first scheduled timing of causing the transmitter to be operable to transmit wireless communications during a transmit window and causing the receiver to be operable to receive wireless communications during a separate receive window for each wireless device of the first plurality of sensor nodes based on the timing separation and a periodic beacon signal of the first hub, wherein the timeslot definition signal is separate from the periodic beacon signal.

Abstract
In one embodiment, a system includes a hub having one or more processing units and RF circuitry for transmitting and receiving communications in a wireless network architecture. The system includes a plurality of sensor nodes each having a wireless device with a transmitter and a receiver to enable bi-directional communications with the hub in the wireless network architecture. The one or more processing units of the hub are configured to execute instructions to determine a first scheduled timing of causing the transmitter to be operable to transmit and causing the receiver to be operable to receive for each wireless device based on a periodic beacon signal of the hub.
