Appl. No.:

09/764779

Inventors:

Ronald D. Fellman - San Diego CA
Rene L. Cruz - San Diego CA
Douglas A. Palmer - San Diego CA

Assignee:

Path 1 Network Technologies, Inc. - San Diego CA

International Classification:

H04L 1228

US Classification:

370420, 370445, 370463, 370437, 370461

Abstract:

An arbitration mechanism provides quality of service guarantees for time-sensitive signals sharing a local area computer network with non-time-sensitive traffic. Device adapters are placed at all access points to an Ethernet network. The device adapters limit admission rates and control the timing of all packets entering the network. By doing so, collisions are eliminated for time-sensitive traffic, thereby guaranteeing timely delivery. A common time reference is established for the device adapters. The time reference includes a frame with a plurality of phases. Each of the phases is assigned to a device adapter. Each device adapter is allowed to transmit packets of data onto the network only during the phase assigned thereto. The length of the phases may be modified in accordance with the number of packets to be transmitted by a particular device adapter. A master device adapter may be appointed to synchronize each of the device adapters.

International Classification:

H04B 7/185
H04B 7/00

US Classification:

370318, 455522

Abstract:

The invention concerns routing, scheduling, and power control methods for single and multi-hop wireless networks. A multi-hop network is one in which source and destination nodes may communicate directly or through relay nodes. Nodes in single hop networks communicate without use of relay nodes. Embodiments of the invention may produce an optimal schedule to provide for the best-case goal for a given parameter. In a preferred embodiment, total power is the parameter and total power is minimized for the network. In another preferred embodiment, data throughput is the parameter, and throughput is maximized for the network.

US Classification:

370351, 370395, 370461, 709227

Abstract:

Methods, systems and devices for sharing communication resources among a plurality of clients (-) that are part of a common wireless community (). The communication resources are, for example, Internet access resources (-). Another example, might be a video or data delivery communication resource. As an example, clients have separate Internet access accounts. Embodiments of the invention, for example, allow client business units or residential units to share separate Internet access accounts.

International Classification:

H04L 12/28

US Classification:

3703952, 37039521, 3703953, 370437

Abstract:

The system provides a low cost way of providing high speed point to point communications between two offices, as well as Internet access, which exploits the use of low cost access technologies, such as ADSL, in such a way that (a) no CO component is required to deploy the solution, (b) the two offices could have different types of communication technologies available, and (c) more than two offices can form an overlay network, whereby each pair of offices has a virtual single high throughput pipe available which is achieved through aggregation of Internet access services at each office. The proposed system allows intranet communication links or Internet connections to be aggregated, thereby enabling faster and more reliable communications.

Abstract:

Receivers and reception methods conduct spread spectrum reception using the energy of multiple bits, preferably a substantial number of bits, in a packet for correct alignment of the spreading code at the receiver. Code acquisition, as well as packet detection and acquisition are provided by embodiments of the invention. Preferred embodiment receivers and reception methods provide packet detection at low SINR looking at energy of multiple bits of the packet, frame synchronization using short preamble, timing recovery at low SINR looking at energy of multiple bits of the packet, quick code acquisition using parallel search for all possible code phases, code acquisition at low SINR, and tracking of acquired timing and code phase. Preferred embodiment receivers and reception methods use the energy of multiple bits for making decisions.
