International Classification:

US Classification:

370338, 370349, 37039552, 455445

Abstract:

A fixed broadband wireless data access service providing shared wide-band packet-switched data transport for high speed data access in areas where conventional ADSL service and fiber optic service are unavailable. The wireless data access service is a point-to-multipoint cellular-type network that connects customers to data service providers through the ATM backbone of an existing network. Customers connect to the ATM backbone and data service provider through a cellular grid in which a wireless base station in each cell communicates with the individual customer wireless equipment within its cell site coverage area. The base stations are connected to an ATM backbone switch through wireless and wireline backhaul links. The upstream and downstream bandwidths of the wireless broadband network are engineered in various symmetric and asymmetric configurations to provide a shared packet-switched connection that emulates an uninterrupted, direct wireline ADSL connection. The wireless broadband network employs a data protocol of shared access bandwidth and adaptive asymmetric data rates to support multiuser service sessions by wireless transmission.

International Classification:

H04M 1/00

US Classification:

4555621, 455561, 342368, 343757

Abstract:

An array antenna is utilized to enhance the adaptive acquisition capability of a communication connection with one or more wireless subscribers. Subscribers who are located outside the omnidirectional range of the array antenna are acquired by using adaptive beamforming techniques to create an acquisition beam dedicated to acquiring new connections with wireless subscribers. The acquisition beam may sweep through the coverage of the array antenna seeking subscribers who lie beyond the omni range of the array antenna, but fall within the acquisition range using adaptive beamforming.

Abstract:

Mobile service anchor management (MSAM) is facilitated. MSAM is an anchor management function/system for radio frequency (RF) access configuration/reconfiguration over the downlink, and uplink separated novel frequency division duplex systems. One method comprises determining, by a MSAM system comprising a processor, that a mobile device communicatively coupled to a first network device is associated with a region in which the first network device fails to have line of sight communication with the mobile device; and assigning, by the mobile service anchor management system, the mobile device to a second network device determined to have the line of sight communication for the region. Millimeter watt (mmW) BS devices and devices that operate on other RF bands can be utilized.
