Heterogeneous network optimization utilizing modal antenna techniques
A communication system is described where multiple communication networks are simultaneously accessible from a plurality of fixed and/or mobile communication devices. A Master and Slave hierarchy is implemented among the communication devices to improve communication properties on one or multiple networks. A network system controller is implemented to select the network with optimal communication characteristics for subsets of communication devices as well as assigning Master status to a communication device within these subsets.
1. A method for controlling communications in a communication system having a first communication network and a second communication network, the first communication network implementing a different protocol or modulation scheme relative to the second communication network, the method comprising:
obtaining a designation as a master device in the communication system;
obtaining data indicative of communication link performance for one or more slave devices in the communication system, the one or more slave devices comprises a modal antenna capable of generating two or more radiation modes in each of the first communication network and the second communication network, each radiation mode associated with a different radiation pattern;
selecting, for each of the one or more slave devices, a determined network from the first network and the second network for sending one or more communications based at least in part on the data indicative of communication link performance;
selecting for each of the one or more slave devices, a determined radiation mode from the two or more radiation modes for sending one or more communications; and
controlling the one or more slave devices based at least in part on the determined network and the determined radiation mode.
2. The method of claim 1 , wherein the determined radiation mode is selected based at least in part on the data indicative of communication link performance.
3. The method of claim 1 , wherein controlling the one or more slave devices is implemented by the master device.
4. The method of claim 1 , wherein the first network is a cellular network.
5. The method of claim 4 , wherein the second network is a wireless local area network.
6. The method of claim 4 , wherein selecting for each of the one or more slave devices, a determined radiation mode from the two or more radiation modes for sending one or more communications comprises selecting, for each of the one or more slave devices, a determined radiation mode from the two or more radiation modes for sending one or more communications via the determined network.
7. The method of claim 4 , wherein selecting for each of the one or more slave devices, a determined radiation mode from the two or more radiation modes for sending one or more communications comprises selecting, for each of the one or more slave devices, a determined radiation mode from the two or more radiation modes for sending one or more communications with another slave device.
8. The method of claim 1 , wherein the master device has higher communication link quality with the first network relative to each of the one or more slave devices.
