Abstract: A scalable medium access control (“MAC”) module is provided that avoids conflict resource reservation so that network performance does not degrade as the number of hops or nodes in a wireless network increases. The MAC also provides different access schemes for traffic with different quality of service (“QoS”) requirements such that QoS is guaranteed and network resources are efficiently utilized. Furthermore, the resource allocation scheme determines the routing path as resources is allocated for data traffic, thereby achieving more robust layer-2 routing at the MAC layer. Finally, the scalable MAC is compliant with both WiMedia MAC and IEEE 802.15.3 MAC.

Abstract: Systems and methods for determining a location of a device with a wireless network. Characteristics of signals received from the device at a plurality of nodes are measured. Based upon the measurements, estimates of the range from the device to the nodes are made. Then, based upon the estimated ranges, and knowing the location of the nodes, a location of the device is determined.

Abstract: A distributed multi-channel TDMA MAC time slot and channel allocation algorithm for wireless networks is provided. The time slot and channel allocation includes a distributed allocation phase and an allocation adjustment phase. Each phase begins allocation at a first node and continues node-by-node until the last node in the network. The allocation then reflects back from the last node to the first node. At each node in the path, the node can initiate resource allocation between itself and its neighbor nodes. Nodes that are within range of the wireless network but are not on the path do not initiate resource allocation but instead participate in the resource allocation initiated from other nodes.

Abstract: A wireless communication system is provided that has at least three nodes arranged in a multi-hop ultra wide band (UWB) communication network such that communications from a first node destined for a third node pass through a second node. Each of the devices in the system includes a radio and a media access control (“MAC”) module that is configured to establish multi-hop UWB wireless communications between the three or more wireless communication devices that enables high bandwidth applications such as Voice Over Internet Protocol (“VoIP”); multiplayer gaming; Wireless High Definition Television; and Internet Protocol Television (“IPTV”) among others. The MAC module is configured to avoid bandwidth reservation conflicts so that network performance does not degrade as the number of hops or the number of nodes in the wireless communication system increases.

Abstract: Systems and methods are provided that facilitate distributed multichannel wireless communication and provide the highest level quality of service (“QoS”) guarantee and support extremely high bandwidth applications such as voice over internet protocol (“VOIP”) streaming audio and video content (including high definition), and multicast applications and also supports convergent networks, ad hoc networks, and the like. A modular MAC architecture provides a group of nodes with the ability to simultaneously communicate with each other using multiple separate communication channels during the same timeslots. The additional throughput gained by employing multiple communication channels is amplified by dynamically mapping the communication channels and timeslots in a network so that multiple channels can be reused simultaneously throughout the network during the same timeslot in a fashion that does not create collisions.
