Abstract
A data communication system wherein four independent frequencies provide for transmissions between a communication controller and at least one node including a first node. The four independent frequencies include: an aligning signal sent on a first frequency, a request signal in a slot allocated to a first node for transmitting reserved request sent on a second frequency, a authorization signal sent on a third frequency and data packets sent over a fourth frequency. In addition, data packets sent over the data communication system can include information related to a count value and termination indication information for determining whether the message has been completely received.
