1. A system for providing a wireless asymmetric network, comprising:

  • a hub having one or more processing units and at least one antenna for transmitting and receiving radio frequency (RF) communications in the wireless asymmetric network;

    a plurality of sensor nodes each having a wireless device with a transmitter and a receiver to enable bi-directional RF communications with the hub in the wireless asymmetric network to determine localization of the plurality of sensor nodes within the wireless asymmetric network, to monitor loading zones and adjacent regions within a building based on receiving information from at least two sensor nodes including at least one indoor node and at least one outdoor node, and to determine for each loading zone whether a vehicle currently occupies the loading zone wherein at least one of image data, RF data from the RF signals, and RF tracking data from the indoor node and at least one of image data, RF data from the RF signals, and RF tracking data from the outdoor node are utilized in combination to monitor a dynamically changing environment of the interior region and whether a vehicle occupies the loading zone.
