Abstract

Methods, apparatus, systems and articles of manufacture to attempt to establish a connection with a wireless network are disclosed. An example method includes determining a location of a field device. A frequency at which retry attempts to establish a connection with a wireless network are to be made is determined based on the location of the field device. Establishing the connection with the wireless network is attempted. In response to a failure to establish the connection with the wireless network, an indication of the failure to establish the connection and the location of the field device is stored, and the field device waits an amount of time based on the frequency.

Claims

1. An apparatus to attempt to establish a connection with a wireless network, the apparatus comprising:

a location determiner to determine a location of the apparatus;

a frequency determiner to determine a frequency at which retry attempts to establish a connection with a wireless network are to be made based on the location of the apparatus;

a wireless communicator; and

a connection processor to cause the wireless communicator to attempt to establish the connection with the wireless network, and, in response to a failure to establish the connection with the wireless network;

(1) store an indication of the failure to establish the connection and the location of the apparatus, and (2) wait an amount of time based on the frequency.

2. The apparatus as described in claim 1, further including a coverage server interface to, in response to successfully establishing the connection, transmit the stored indication of the failure to establish the connection and the location of the apparatus to a coverage data processor.

3. The apparatus as described in claim 1, wherein the frequency determiner is to determine the frequency by identifying a probability of establishing the connection with the wireless network using the location of the apparatus, and identifying the frequency based on the probability of establishing the connection.

4. The apparatus as described in claim 3, wherein the frequency determiner is to identify the frequency by calculating the frequency using a linear equation.

5. The apparatus as described in claim 3, wherein the frequency determiner is to identify the frequency by performing a lookup using the probability.

6. The apparatus as described in claim 3, wherein the frequency determiner is to determine the probability of establishing the connection with the wireless network using a probability map stored in a local probability data store of the apparatus, and further including:

a coverage server interface to, in response to successfully establishing the connection, retrieve an updated probability map from a coverage data processor.

7. The apparatus as described in claim 6, wherein the coverage server interface is further to, in response to successfully establishing the connection, transmit a log of connection failures to the coverage data processor, the log of connection failures including the stored indication of the failure to establish the connection and the location of the apparatus, the probability map retrieved from the coverage data processor is created by the coverage data processor using the log of connection failures.

8. The apparatus as described in claim 1, wherein the location determiner is to use dead reckoning to identify the location of the apparatus.
