1. A host device for wirelessly receiving messages from a plurality of client devices, the host device comprising:

  • a memory configured to store a frequency hopping sequence, the frequency hopping sequence including a plurality of predetermined frequencies arranged in a predetermined order from a first predetermined frequency to a last predetermined frequency;

    a controller operatively coupled to the memory; and

    a receiver operatively coupled to the controller and configured to accept from the controller a frequency selection input that selects one of the predetermined frequencies of the frequency hopping sequence and the receiver listens for a message from the plurality of client devices on the selected one of the predetermined frequencies;

    the controller is configured to provide a sequence of frequency selection inputs to the receiver that repeatedly cycles through the frequency hopping sequence stored in the memory, wherein each cycle through the frequency hopping sequence is defined as a channel, and wherein the controller repeatedly cycles through two or more channels from a first channel to a last channel;

    wherein when a reserving client device of the plurality of client devices reserves one or more channels, resulting in one or more reserved channels, and the remaining client devices are informed of the reservation and in response do not transmit messages during the one or more reserved channels, the controller of the host device receives via the receiver one or more messages from only the reserving client device during the one or more reserved channels; and

    the controller of the host device is configured to receive via the receiver a message from one or more of the plurality of client devices during one or more of the channels that are not part of the one or more reserved channels.
