What is claimed is: 1. An apparatus for acquiring seismic data, comprising: a circuit configured to receive signals from a seismic sensor; a data storage device configured to store therein information about a plurality of attributes relating to the acquisition of seismic data; and a processor configured to utilize the information in the data storage device to: determine a value of each attribute when the apparatus is deployed to receive signals from the seismic sensor; generate a message indicative of an alarm condition when the determined value of any attribute in the plurality of attributes meets a criterion set for that attribute; send each generated message wirelessly to a remote unit; and use a filter provided to the processor for a particular attribute to refrain from sending or generating a message for the particular attribute. 2. The apparatus of claim 1, wherein the processor is configured to automatically send each message to the remote unit. 3. The apparatus of claim 1, wherein the processor is configured to perform a data compression by preparing a common data packet for a plurality of messages generated during a preselected time period. 4. The apparatus of claim 1, wherein the processor is configured to prioritize the generated messages prior to sending the messages to the remote unit. 5. The apparatus of claim 1, wherein the processor is configured to assign a unique identifier to each generated message, which identifier is selected from a group consisting of: (i) an identification number of the apparatus; (ii) an identification number of the apparatus and a time slot for the message; (iii) a variable value; (iv) a fixed value; and (v) a random number generated by a random number generator. 6. The apparatus of claim 1, wherein the processor is configured to limit the number of messages transmitted in a preselected time period based on one of: (i) instructions stored in the data storage device; and (ii) instructions received from the remote unit. 7. The apparatus of claim 1, wherein the processor is further configured to re-transmit each alarm signals for which no acknowledgment is received by the apparatus from the remote unit within a selected time period. 8. The apparatus of claim 7, wherein the processor is configured to limit the number of times it transmits a particular message to the remote unit. 9. The apparatus of claim 1, wherein the attribute is selected from a group consisting of: (i) a power source condition; (ii) a motion sensor measurement; (iii) a shot condition; (iv) a data storage medium condition; (v) a timing error condition; (vi) a seismic alarm condition; (vii) an environmental parameter condition; (viii) a configuration error condition; (ix) a data download condition; (x) a software condition; (xi) a noise condition; (xii) a device initiated activity including one of (a) status of turning off a device, and (b) a status of turning on a device associated with the apparatus; (xiii) a pre-shot test condition; and (xiv) a synchronization condition. 10. A method of acquiring seismic data, comprising: defining a plurality of attributes relating to acquisition of seismic data by a field service unit; determining a value of each attribute when the field service unit is deployed at a field location: generating a message for each attribute whose determined value meets a selected criterion; transmitting wirelessly each generated message to a remote unit without solicitation of such a message by the remote unit; and blocking transmission of a particular generated message using a filter provided to the field service unit relating to the particular generated message. 11. The method of claim 10, wherein the selected criterion corresponds to one of: the determined value is above a threshold value; the determined value is below a threshold value; and the determined value is outside a range of values. 12. The method of claim 10, further comprising performing a data compression by preparing a common data packet for a plurality of the messages generated during a preselected time period. 13. The method of claim 10 further comprising prioritizing messages that are generated in preselected time prior to transmitting such messages to the remote unit. 14. The method of claim 10 further comprising assigning a unique identifier to each message, which identifier is one of: (i) an identification number relating to the field service unit; (ii) an identification number relating to the field service unit and time slot for the alarm signal; (iii) a variable value; (iv) a fixed value; and (v) a random number generated by a random number generator. 15. The method of claim 10 further comprising automatically retransmitting a message for which no acknowledgment is received from the remote unit within a selected time period. 16. The method of claim 10, wherein the attribute is selected from a group consisting of: (i) a power source condition; (ii) a motion sensor measurement; (iii) a shot condition; (iv) a data storage medium condition; (v) a timing error condition; (vi) a seismic alarm condition; (vii) an environmental parameter condition; (viii) a configuration error condition; (ix) a data download condition; (x) a software condition; (xi) a noise condition; (xii) a device initiated activity including one of (a) status of turning off a device, and (b) a status of turning on a device associated with the apparatus; (xiii) a pre-shot test condition; and (xiv) a synchronization condition. 17. A computer-readable medium accessible to a processor containing a computer program embedded therein, wherein the computer program comprises: instructions to receive signals from a seismic sensor; instructions to determine a value for each of a plurality of attributes relating to acquisition of the seismic data; instructions to generate a message for each attribute in the plurality of attributes when the determined value of that attribute meets a selected criterion set for that attribute; instructions to cause wireless transmission of each generated message to a remote unit without prior solicitation of such alarms by the remote unit; and instructions to block transmission of a particular generated message using a filter provided to the field service unit relating to the generated message. 18. The computer-readable medium of claim 17, wherein the computer program further comprises instructions to prioritize the generated messages based on a selected criterion. 19. The computer-readable medium of claim 17, wherein the computer program further comprises instructions to prepare a common data packet for a plurality of the generated messages. 20. The computer-readable medium of claim 17, wherein the computer program further comprises instructions to assign a unique identifier that is one of: (i) an identification number of an apparatus; (ii) an identification number of an apparatus and a time slot for the message; (iii) a variable value; (iv) a fixed value; and (v) a random number generated by a random number generator. 21. The computer-readable medium of claim 17, wherein the computer program further comprises instructions to limit the number of messages that are transmitted to the remote unit within a selected time period. 22. The computer-readable medium of claim 17, wherein the computer program further comprises instructions to retransmit a message for which an acknowledgement is not received from the remote unit.
