DATA COMMUNICATION USING A PRIVATE PREAMBLE
First Claim
Patent Images
1. A method, comprising:
- detecting, by a computing node, a data stream;
determining, by the computing node, whether the received data stream includes a private preamble known to the computing node; and
if it is determined that the data stream includes a private preamble known to the computing node, receiving, by the computing node, a targeted data stream intended for the computing node.

Abstract
Examples of data communication using a private preamble are disclosed. In one example implementation according to aspects of the present disclosure, a data stream is detected. It is then determined whether the received data stream includes a private preamble known to the computing node. If it is determined that the data stream includes a private preamble known to the computing node, a targeted data stream intended for the computing node is received by the computing node.

8. A method, comprising
detecting, by a computing node, an incoming hailing data packet; -
determining, by the computing node, whether the incoming hailing data packet includes a known private preamble; if it is determined that the hailing data packet includes the known private preamble, receiving, by the computing node, the hailing data packet during a hailing listening period on a set of a plurality of non-frequency hopping spread spectrum (non-FHSS) channels; and receiving, by the computing node, a targeted data stream intended for the computing node. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A computing system, comprising:
-
a sending node; and a receiving node, wherein the sending node further comprises a hailing module configured to hail a receiving node by transmitting a hailing data packet over at least one of a set of a plurality of non-frequency hopping spread spectrum (non-FHSS) channels, the hailing data packet including a private preamble, and a data transmission module configured to transmit data to the receiving node after receiving a hailing acknowledgement from the receiving node, and wherein the receiving node further comprises a channel activity detector module configured to detect the private preamble on at least one of the set of the plurality of non-FHSS channels, to determine that the private preamble is a known private preamble, and to receive a hailing data packet during a hailing listening period on the set of the plurality of non-FHSS channels when it is determined that the private preamble is a known private preamble, an acknowledgement module configured to transmit a hailing acknowledgement to the sending node after detecting the private preamble and receiving the hailing data packet, and a data receiving module configured to receive the data transmitted by the sending node. - View Dependent Claims (17, 18, 19, 20)
