Operator Supervisor for Fleet Management DispatchBand- Jobs in Afghanistan

The equipment is therefore often more expensive than similar equipment for other services, even though that other equipment may be more sophisticated than the needed equipment. The reasons for this are complex, involving the scale of production as well as the lack of competition. The method of claim 54 further comprising notifying said recipient of a delayed dispatch.

Those skilled in the art will appreciate that non-circuit-switching services 103 use considerably less bandwidth than circuit-switching services 100. This, coupled with the significant reduction in allocation and transmission time, produces a significant reduction in the overall expenditure of system resources in network 24. This in turn produces a significant reduction in operating expenses.

One answer to the eavesdropping problem is to encrypt the information. This is a straightforward procedure in digital systems, but somewhat cumbersome and expensive in analog systems. While encoding can be successfully used in critical PTT dispatching services (police, fire, etc.), it is often cost-prohibitive for business systems. Again, because the dispatch unit of a PTT dispatch system is inherently different than a field unit, a field unit cannot normally be used as an alternative dispatch unit in the event of failure of the dispatch unit. Therefore, the integrity of the entire system depends upon the integrity of a single dispatch unit.

The dispatching unit is typically a fixed “base station.” As such, the dispatching unit is tied to mains service and is not mobile. This causes PTT dispatching systems to be severely handicapped during fluid situations where the base station may be lost. To cover for such circumstances, a “mobile base unit” may be used, typically an alternative base station mounted in a truck or other vehicle. Such a mobile base station adds significantly to the overall expense of a PTT system. The expense involved often drives such a feature beyond the range of small communities who, ironically, may best benefit from it.

Destination unit 28 receives information packet 22 configured as destination packet 52. Destination packet 52 may assume any of several embodiments (FIGS. 3, 4, and 5) within system 20. The first problem encountered when replacing a PTT Dispatch App system with a cellular telephone system is that of overkill. The replacement of a simplex communication system with a full-duplex system represents a significant waste of resources. Not only must adequate bandwidth for full duplex communication be allocated, it often must be allocated for the full duration of the conversation, i.e., from the time the connection is made until the parties hang up. These inefficiencies are a result of the circuit-switching services of cellular telephony, and are directly translatable into fiscal losses.
