Abstract
A wireless monitoring system comprises a remote asset about which data is to be collected and a wireless data-transfer device connected to the remote asset. The wireless device includes a radiofrequency transceiver and a chip having a memory for storing a plurality of subscriber identifiers corresponding to different wireless networks and for further storing logic that constitutes network selection rules for selecting one of the wireless networks to use for transmission of the data. In a GSM/UMTS implementation of this technology, the subscriber identifier is the IMSI and the chip is a Subscriber Identity Module (SIM) chip or card. By using multiple IMSI's, the wireless data-transfer device connected to the remote asset may switch seamlessly between wireless networks. A new IMSI (for a new network) may be provisioned over the air to enable the device to communicate over a new network for which it did not previously have an IMSI.
