wherein location information characterizing at least a first one of said locations is transmitted from said wandering devices to said tracking functionality using Unstructured Supplementary Service Data (USSD),

wherein location information characterizing at least a second one of said locations is transmitted from said wandering devices to said tracking functionality using at least one communication channel other than USSD, and

wherein at least one choice between USSD and at least one communication channel other than USSD is made in real time based on a comparison in real time of computerized data representing current cost effectiveness values for USSD and for said at least one communication channel other than USSD, respectively

wherein the system has at least one server which adjusts communication channels to minimize cost and load on network infrastructure and wherein messages sent between the wandering devices and the at least one server include;

at least one Control Message sent from the server to a wandering device TGD, to control/configure/command;

at least one Notification Message sent from the wandering device TGD to the server to notify of a specific event/alert; and

a flow of messages sent, at least in a tracking mode, from the wandering device TGD to the server.

2. The system according to claim 1, wherein first and second wandering devices from among said population are located in first and second countries respectively served by a high-cost high-reliability communication channel and a low-cost high-reliability communication channel and wherein location information is transmitted from said first and second wandering devices to said tracking functionality using a low-reliability communication channel and said low-cost high-reliability communication channel respectively, based on stored information regarding costs of high-reliability communication channel usage in said first and second countries.

3. The system according to claim 1, wherein said tracking functionality communicates with said population of wandering devices using a higher-reliability communication channel or a lower-reliability communication channel, and wherein one of said channels is selected for usage based on a comparison of current relative cost effectiveness of said two channels.

4. The system according to claim 1, wherein at least one control message includes Cooldown data stipulating a time interval to wait before sending a new notification in a continuous mode.

5. The system according to claim 1, wherein at least one Notification Message includes a Get History element which enables historical location data stored in the device to be pulled due to loss of coverage.

6. The system according to claim 1, wherein at least one Notification Message includes an indication of a number of locations sent in said notification Message and an indication of a number of locations left in device storage after sending said notification Message.

7. The system according to claim 1, wherein at least one Notification Message includes an indication of a location and a speed stored in the wandering device TGD.

8. The system according to claim 1, wherein a Delta Compression Mode is provided and when the delta compression mode is on, some locations are, when transmitted, represented only by their difference from another location.

9. The system according to claim 1, wherein location information is transmitted via a GSM chipset over a GSM cellular network to said at least one server which makes location data available to at least one of the end-users via a viewing functionality.

10. The system according to claim 1, wherein a channel used for transmitting an upcoming set of data units is selected based at least partly on whether the type of channel is cellular data or USSD.

11. The system according to claim 10, wherein the data channel is prioritized except in areas where the data channel is more expensive than a predetermined threshold.

12. The system according to claim 1, wherein a channel used for transmitting an upcoming set of data units is selected based at least partly on the assumed quality of a channel in the area where the device is located such that if stored history indicates that a data channel is less reliable, the USSD may be prioritized relative to the data channel.

13. The system according to claim 1, wherein a channel used for transmitting an upcoming set of data units is selected based at least partly on the actual quality of the channel as experienced in real time such that if transmission attempted over one type of channel yields unexpected errors or delays, a different channel is tried.

14. The system according to claim 1, wherein a channel used for transmitting an upcoming set of data units is selected based at least partly on indications of high load on the communication network at a given time.

15. The system according to claim 9, wherein said viewing functionality is provided by an app on a mobile device via which at least one of the end-users is logged on to the system and wherein apps interact with the at least one server rather than directly with the wandering devices and wherein the at least one server sends commands to and gets at least one of status reports, alerts and notifications from the wandering devices, and updates the apps accordingly.

16. The system according to claim 1, wherein each individual wandering device is commanded to operate in tracking mode or not by the at least one server and only when in tracking mode, the individual device periodically samples its location and periodically transmits an indication of the location to the server where at least one of the sampling and reporting periods are as per command from the server.

17. The system according to claim 16, wherein at least one individual wandering device is commanded by the server to operate in normal mode in which the individual device is connected to the network and waiting for a communication event from the server, and is ready to transmit to the server any local events including alarms.
