The medium of claim 17, further comprising a defining code segment that defines priorities based upon user defined criteria.

The medium of claim 17, further comprising a modifying code segment that dynamically modifies the priority of each wireless network.

The medium of claim 17, in which the availability code segment further comprises determining if a previous network is available; and</claim-text> the selecting code segment further comprises selecting the previous network as the current most rred network when the previous network is available and the previous network is a higher priority than a current network. view more

The medium of claim 22, in which the availability code segment further comprises determining if a next network is available when the previous network is not available; and</claim-text> the selecting code segment further comprises selecting the next rk as the current most preferred network when the next network is available and the next network is a higher priority than the current network. view more

A computer readable medium storing a program for dynamically routing data over multiple dissimilar parallel wireless networks that are each monitored for status information, the medium comprising:</claim-text> an availability code segment that tains availability of at least two of the wireless networks based upon the status information; a determining code segment that determines whether to switch between networks when at least two networks are available, in response to a user configuration and each network's speed; and a switching code segment that switches from a first available network to a second available network, which is dissimilar at a link layer from the first available network, during a transmission while remaining connected to both the first network and the second network for a period of time. view more

The medium of claim 39, further comprising a packet size code segment that determines a packet size prior to transmitting data.

A mobile system, comprising:</claim-text> a local device comprising a database server application, the local device residing on a local area network; a server connected to the local device via the local area network, the server being connected to a lity of incompatible wireless networks; and a mobile device connected to the plurality of incompatible wireless networks, the mobile device being associated with a plurality of transmitters, each transmitter operating with one of the dissimilar networks, the mobile device comprising a client application that enables a remote user to send and retrieve data from the database server application via the server, the mobile device sending data to the database server application via at least two of the plurality of incompatible wireless networks while switching between the at least two incompatible wireless networks, and remaining connected to the at least two incompatible wireless networks for a period of time after switching. view more

A method for dynamically routing data over multiple dissimilar parallel wireless networks that are each monitored for status information, the multiple wireless networks being simultaneously in coverage, each wireless network being associated with a transmitter, the method comprising: maintaining a priority of each wireless network, the priorities indicating a most preferred network; determining availability of each wireless network based upon status information associated with each wireless network, including determining if a previous network is available, and determining if a next network is available when the previous network is not available or is a lower priority than a current network; indicating a current most preferred network from the wireless networks determined to be available, the indication being based upon the network priorities, the current most preferred network comprising the previous network when the previous network is available and the previous network is a higher priority than the current network, which is dissimilar at the link layer from the current most preferred network; switching from the current network to the current most preferred network, which has a higher priority, during a transmission when the higher priority network becomes available; interrupting transmitting over the current network after switching to the current most preferred network; and remaining connected to the current network for a period of time after switching to the current most preferred network. view more

The computer readable medium of claim 48, in which the switching further comprises switching to the next available network, immediately after transporting a first data packet and before transporting a subsequent consecutive data packet, when the monitoring determines that the first network is unavailable for data transport. view more

The computer readable medium of claim 59, in which the switching further comprises switching communications links immediately after transporting a first data packet and before transporting a subsequent consecutive data packet.

The computer readable medium of claim 66, in which the switching further comprises switching communications links immediately after transporting a first data packet and before transporting a subsequent consecutive data packet.
