A method for communicating data between a central data terminal, a plurality of intermediate data terminals, a plurality of remote cell nodes, and a plurality of network service modules, using a plurality of frames with each frame having a plurality of channels. The plurality of intermediate data terminals transmit IDT-synchronization signals to the plurality of remote cell nodes on a first channel of the frame. The plurality of remote cell nodes transmit RCN-synchronization signals to the plurality of network service modules on a second channel of the frame. The network service modules transmit data from a plurality of physical devices, using radio waves, as NSM-packet signals to the plurality of remote cell nodes using a fourth channel of the frame. The plurality of remote cell nodes store the incoming NSM-packet signals and, responsive to a first polling signal transmitted in a third channel of the frame from a particular intermediate data terminal, transmit the NSM-packet signals to the intermediate data terminal as RCN-packet signals on a fifth channel of the frame. The intermediate data terminal in turn stores the RCN-packet signals received from the plurality of remote cell nodes and, responsive to a second polling signal transmitted from the central data terminal on a sixth channel of the frame, transmits the RCN-packet signals as an IDT-packet signal on a seventh channel of the frame to the central data terminal.

A method for communicating between an intermediate data terminal (IDT), a plurality of remote cell nodes (RCN), and a plurality of network service modules (NSM), using a plurality of frames with each frame having a plurality of channels, comprising the steps, during each frame, of: transmitting, in a first channel of the frame, from the intermediate data terminal to the plurality of remote cell nodes, an IDT-synchronization signal; transmitting, synchronized to the IDT-synchronization signal in a second channel of the frame, from the intermediate data terminal to a first remote cell node, a first polling signal; receiving, at each of the plurality of remote cell nodes, the IDT-synchronization signal; synchronizing, at each of the plurality of remote cell nodes, responsive to receiving the IDT-synchronization signal, an RCN-timing circuit to the IDT-synchronization signal; receiving, at the first remote cell node, the first polling signal; transmitting, synchronized to the IDT-synchronization signal in a third channel of the frame, from the first remote cell node to the intermediate data terminal, responsive to the first polling signal, an RCN-packet signal; transmitting, using radio waves, in a fourth channel of the frame, from each of the plurality of remote cell nodes to the plurality of network service modules, responsive to receiving and synchronizing to the IDT-sychronization signal, an RCN-synchronization signal; receiving, at each of the plurality of network service modules, the RCN-synchronization signal; synchronizing, at each of the plurality of network service modules, responsive to receiving the RCN-synchronization signal, a NSM-timing circuit to the RCN-synchronization signal; collecting, at a first network service module, data from a first physical device; and transmitting, using radio waves, responsive to receiving and synchronizing to the RCN-synchronization signal synchronized to the IDT-synchronization signal, in a fifth channel of the frame, from the first network service module to at least one of the plurality of remote cell nodes, a first NSM-packet signal containing the data from the first physical device.
