Patent ID: 7940736

Claim:
A wireless two-way radio frequency (RF) data communication device comprising a data packet radio component, the wireless two-way RF data communication device being configured to: (a) receive RF transmissions; (b) maintain at least one common designation for purposes of filtering RF transmissions received by the wireless two-way RF data communication device, wherein the at least one maintained common designation comprises at least one maintained class designation; (c) identify specific data in a received RF transmission; and (d) in response to the received RF transmission in which the specific data is identified, (i) transmit a response using the data packet radio component if the identified specific data corresponds to at least one maintained common designation, and (ii) not transmit a response using the data packet radio component if the identified specific data does not correspond to at least one maintained common designation, (iii) wherein the identified specific data is found to correspond to at least one maintained common designation when the identified specific data matches an abstracted class of a maintained class designation, whereby the wireless two-way RF data communication device selectively responds to RF transmissions.
