Abstract

A method for operating a receiver and a device are provided. The device comprises a first and a second antenna, a receiver operationally coupled to the first antenna and a transceiver operationally coupled to the second antenna. The receiver receives information in bursts on a first band of radio frequencies. A controller of the device measures signal strength of the information received with the receiver, compares the measured signal strength to a reference value and enables operation of the transceiver if the measured signal strength is above the reference value, and limits operation of the transceiver during reception of the bursts if the measured signal strength is below the reference value.

First claim

The invention claimed is:

1. In a device comprising a coupling to a first antenna and a second antenna, a method for operating a receiver comprising a coupling to the first antenna in combination with a transmitter comprising a coupling to the second antenna, the method comprising:
receiving information in bursts with the receiver on a first band of radio frequencies,
measuring signal strength of the information received with the receiver,
comparing the measured signal strength to a reference value, and
if the measured signal strength is above the reference value,
enabling operation of the transmitter, and
if the measured signal strength is below the reference value, limiting operation of the transmitter during reception of the bursts,
wherein the transmitter is in a GSM network, the method further comprising:
configuring the transmitter to send data as short messages and interrupting transmission when the receiver is receiving bursts.

2. In a device comprising a coupling to a first antenna and a second antenna, a method for operating a receiver comprising a coupling to the first antenna in combination with a transmitter comprising a coupling to the second antenna, the method comprising:
receiving information in bursts with the receiver on a first band of radio frequencies,
measuring signal strength of the information received with the receiver,
comparing the measured signal strength to a reference value, and
if the measured signal strength is above the reference value,
enabling operation of the transmitter, and
if the measured signal strength is below the reference value, limiting operation of the transmitter during reception of the bursts,
wherein the transmitter is in a GSM network, the method further comprising:
configuring the transmitter to send data using GPRS, and timing the transmission to time instants at which the receiver is not receiving bursts.

3. In a device comprising a coupling to a first antenna and a second antenna, a method for operating a receiver comprising a coupling to the first antenna in combination with a transmitter comprising a coupling to the second antenna, the method comprising:
receiving information in bursts with the receiver on a first band of radio frequencies,
measuring signal strength of the information received with the receiver,
comparing the measured signal strength to a reference value, and
if the measured signal strength is above the reference value,
enabling operation of the transmitter, and
if the measured signal strength is below the reference value, limiting operation of the transmitter during reception of the bursts,
wherein the step of limiting the operation of the transmitter during reception of the bursts comprises:
delaying signaling of the transmitter to a time instant at which a burst is not being received.

4. In a device comprising a coupling to a first antenna and a second antenna, a method for operating a receiver comprising a coupling to the first antenna in combination with a transmitter comprising a coupling to the second antenna, the method comprising:
receiving information in bursts with the receiver on a first band of radio frequencies,
measuring signal strength of the information received with the receiver,
comparing the measured signal strength to a reference value, and
if the measured signal strength is above the reference value,
enabling operation of the transmitter, and
if the measured signal strength is below the reference value, limiting operation of the transmitter during reception of the bursts,
the method further comprising: notifying a user of the device before a large amount of data is about to be transmitted or received.

5. In a device comprising a coupling to a first antenna and a second antenna, a method for operating a receiver comprising a coupling to the first antenna in combination with a transmitter comprising a coupling to the second antenna, the method comprising:
receiving information with the receiver on a first band of radio frequencies;
transmitting information from the transmitter in a second band of radio frequencies;
measuring signal strength of the information received with the receiver;
measuring output signal strength of the transmitter;
determining a difference in measured signal strengths; and
controlling the transmitter on the basis of the determination.
