System and method of communication between multiple point-coordinated wireless networks
View Patent ↗A wireless scatternet is provided that has at least two networks, each including a controller and one or more devices. The controller of each network has a usable physical area that indicates the farthest distance to which the controller can successfully communicate. The controllers will pass network information to each other in various ways depending upon the extent of overlap between the networks. If two networks have visible overlap, the controllers will pass the network information directly. If they have hidden overlap, one controller will use a device in the other controller's network to pass the network information. If they have indirect overlap, one device from each network will together in a child network, and the controllers will pass the network information via the devices in this child network. The network information may be passed through beacons or a separate broadcast message.
1. An ultrawide bandwidth wireless scatternet, comprising:
a first network including
a first controller for controlling operation of the first network, the first controller having a first usable physical area indicating a farthest distance to which the first controller can successfully communicate, and
one or more first devices located in the first usable physical area; and a second network including
a second controller for controlling operation of the second network, the second controller having a second usable physical area indicating a farthest distance to which the second controller can successfully communicate; and
one or more second devices located in the second usable physical area,
wherein one of the one or more first devices is a controller-capable device,
wherein the controller-capable device operates as a child network controller for controlling operation of a child network, the child network controller having a child network usable physical area indicating a farthest distance to which the child network controller can successfully communicate,
wherein at least one of the one or more second devices is within the child network usable physical area and operates as a child device in the child network, and
wherein the first and second controllers exchange network information data via the child controller and the child device in the child network.
2. An ultrawide bandwidth wireless scatternet, as recited in claim 1 , wherein the network information data includes at least one of: a router/controller identifier, an indicator of an age of the network information data, a count of a number of times the network information data has been passed between controllers or devices, a sequence number, a load feedback, a number of associated network devices, a list of neighborhood media access controller address, a list of supported data rates, a list of available network bridge connections, and a list of available network services.
3. An ultrawide bandwidth wireless scatternet, as recited in claim 1 , wherein the network information data is exchanged in part via an ultrawide bandwidth beacon transmitted by the child controller.
4. An ultrawide bandwidth wireless scatternet, as recited in claim 1 , wherein the network information data is exchanged via first and second ultrawide bandwidth broadcast messages transmitted by the child controller and the child device in the child network.
