Abstract: In a data communications system a scheduler device and multiple client devices communicate with each other over a data communications network. The scheduler device assigns a portion of the system's client devices one or more data rate multiplier values that individually affect a maximum throughput associated with their respectively assigned modulation and coding scheme (MCS). The data rate multiplier value assignment is selected by the scheduler device based on a type MCS or a signal interference plus noise ratio (SINR) value. The assigned data rate multiplier values may result in a hybrid throughput scheduling scenario amongst the client devices.

Abstract: A data communications system includes a controller device and multiple client devices in data communications with each other over a data communications network. The controller device is configured to issue an instruction to a portion of the client devices that instructs them to acquire an interference characteristic associated with one or more external interference source. The interference characteristic may be measured interference magnitudes associated with a frequency of data communications over the data communications link. The portion of client devices transmits the measured interference magnitudes to the controller device. The controller device then determines a location of one or more interference sources based on the transmitted data.

Abstract: In a redundant wireless base station, a first baseband processing unit is coupled to a first radio unit and a second baseband processing unit is coupled to a second radio unit. A link couples the first baseband processing unit and the second baseband processing unit. The link allows at least one of the first baseband processing unit and the second baseband processing unit to one or more of transmit and receive via the first radio unit and the second radio unit. A buffer is associated with the link. The buffer is configured to synchronize one or more of transmission and reception via the first radio unit and the second radio unit.

Abstract: A redundant base station including a first baseband processing unit and at least a second baseband processing unit. The first baseband processing unit and the at least a second baseband processing unit are coupled by a link. The link is configured to communicate activity status information, operational status information, and reset control signals between the first baseband processing unit and the at least a second baseband processing unit.

Abstract: In a redundant wireless base station, a redundancy parameter solicitation is sent by a first baseband processing unit via a multicast to a local area network including at least a second baseband processing unit. Advertised redundancy parameters are received via a multicast to the local area network from the second baseband processing unit.

Abstract: In a redundant wireless network, a first baseband processing unit is defined as an active baseband processing unit and a second baseband processing unit as a standby baseband processing unit. An active address is associated with the first baseband processing unit and a standby address is associated with the second baseband processing unit. Subscriber traffic is routed to the first baseband processing unit via the active address. If the second baseband processing unit becomes an active baseband processing unit and the first baseband processing unit becomes a standby baseband processing unit, he active address is associated with the second baseband processing unit, and the standby address is associated with the first baseband processing unit. Subscriber traffic is routed to the second baseband processing unit via the active address.

Abstract: A system, method, and computer program product for receiving a Session Initiation Protocol (“SIP”) packet and analyzing at least a portion of the SIP packet to determine if the at least a portion of the SIP packet includes a request related to a bandwidth requirement. If the at least a portion of the SIP packet includes a request related to a bandwidth requirement, bandwidth of an air link for voice over IP (“VoIP”) communications over the air link is allocated based upon, at least in part, request related to a bandwidth requirement.

Abstract: A wireless network includes a wireless subscriber station radio-linked to a set of redundant wireless base stations, the set including a primary wireless base station connected to a secondary base station by a link, the link enabling sending and receiving baseband radio data to and from a radio or to and from another base station, a first base radio unit (BRU) connected to the primary wireless base station and a second BRU connected to the secondary base station, a data link connecting the primary wireless base station to the secondary wireless base station.

Abstract: A method includes, in a wireless network including radios operating in a Frequency Division Duplexing (FDD) mode in wireless subscriber stations and wireless base stations, freeing a portion of spectrum to enable deployment of radios operating in a Time Division Duplexing (TDD) mode, replacing a first portion of FDD radios in the wireless subscriber stations and wireless base stations with H-FDD radios to avoid interference between FDD radios and TDD radios, utilizing a guard band frequency of the spectrum between the FDD radios and the TDD radios for operation of the H-FDD radios, and replacing FDD radios in a remaining portion of the wireless network with TDD radios.

Abstract: Methods and apparatus, including computer program products, for determining signal quality in a wireless network. A computer-implemented method in a wireless network includes determining values for parameters of a wireless signal, comparing those values to predetermined parameter threshold values corresponding to those parameters, assigning parameter quality index values to the parameters based on the parameter threshold values, and assigning a signal quality index value to the wireless signal based on the parameter quality index values.
