Abstract

A method and a device are provided for controlling operation of a wireless device (200). The method (500) includes transmitting an initial signal (410) to a controller device (120) in an initial mode (505); receiving initial instructions (420) from the controller device in the initial mode, after transmitting the initial signal (510), the initial instructions identifying an operational mode; setting transmit and receive circuitry in the wireless device to transmit and receive according to the operational mode (515, 520, 525); and transmitting operational signals (430) in the operational mode (530). The wireless device 200 includes an antenna controller (290) and an antenna switch (225) for implementing this method.

Claims

1. A method for controlling the operation of the wireless device, including:

receiving an initial incoming signal from a remote device in a first operational mode;

determining a current level of network congestion of the initial incoming signal;

determining that a second operational mode will be a first possible mode if the current level of network congestion of the initial incoming signal is within a first range;

determining that the second operational mode will be a second possible mode if the current level of network congestion is within a second range;

transmitting instructions to the remote device in the first operational mode to transmit and receive in the second operational mode

receiving an operational incoming signal from a remote device in the second operational mode after transmitting the instructions to the remote device;

determining a current level of network congestion of the operational incoming signal;

determining that a third operational mode will be the first possible mode if the current level of network congestion of the operational incoming signal is within the first range;

determining that the third operational mode will be the second possible mode if the current level of network congestion of the operational incoming signal is within the second range; and

transmitting instructions to the remote device in the second operational mode to transmit and receive in the third operational mode.

2. The method for controlling the operation of the wireless device, as recited in claim 1, wherein the receiving of the operational incoming signal, the determining of the current level of network congestion of the operational incoming signal, the determining that the third operational mode will be the first possible mode if the current level of network congestion of the operational incoming signal is within the first range, the determining that the third operational mode will be the second possible mode if the current level of network congestion of the operational incoming signal is within the second range, and the transmitting the instructions to the remote device are periodically repeated, the third operational mode from a previous iteration being considered the second operational mode for new iteration.
