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.
Claims13
An apparatus to attempt to determine probabilities of establishing a connection with at least one wireless network, the apparatus comprising:
- memory;
- machine readable instructions;
- and
- at least one processor to execute the machine readable instructions to cause the at least one processor to at least:
- convert a coverage map into zones;
- determine percentages of the zones where there is wireless coverage, the wireless coverage indicated by the coverage map;
- store the percentages of the zones as probabilities of establishing connections with the at least one wireless network within the zones in a probability map;
- access connection logs from field devices, the connection logs indicative of connection successes and connection failures with the at least one wireless network for the zones;
- identify the zones having probabilities of establishing connections with the at least one wireless network to be updated;
- aggregate the connection logs from the field devices and remove records of the connection successes and the connection failures that are outside of a threshold period of time;
- determine a number of connection successes and a number of connection attempts for respective ones the zones that occurred within the threshold period of time;
- determining adjusted probabilities for the respective ones of the zones by dividing the number of connection successes for the respective ones of the zones by a total number of connection attempts for the respective ones of the zones;
- store the adjusted probabilities for the respective ones of the zones;
- and
- transmit the probability map to a requesting field device.
A non-transitory computer readable medium comprising instructions which, when executed, cause at least one processor to at least:
- convert a coverage map into zones;

- store the percentages of the zones as probabilities of establishing connections with at least one wireless network within the zones in a probability map;
- access connection logs from field devices, the connection logs indicative of connection successes and connection failures with the at least one wireless network for the zones;
- identify the zones having probabilities of establishing connections with the at least one wireless network to be updated;
- aggregate the connection logs from the field devices and remove records of the connection successes and the connection failures that are outside of a threshold period of time;
- determine a number of connection successes and a number of connection attempts for respective ones the zones that occurred within the threshold period of time;
- determine adjusted probabilities for the respective ones of the zones by dividing the number of connection successes for the respective ones of the zones by a total number of connection attempts for the respective ones of the zones;
- store the adjusted probabilities for the respective ones of the zones;
- and
- transmit the probability map to a requesting field device.
