Abstract: Communication systems, devices, and methods for provisioning one or more auxiliary antennas are provided. A communication system includes a network device and a set of external antennas. The network device includes a set of integral antennas and one or more auxiliary connectors. The integral antennas generate at least one beam pattern defining a first coverage area corresponding, for example, to an area in front of the network device. The external antennas are couplable to the auxiliary connectors to generate one or more beam patterns defining a second coverage area disparate from the first coverage area. The second coverage area corresponds to an area below or behind the network device. A control logic detects and provisions the coupled external antennas based on one or more user inputs or a self-identifying antenna functionality, and by selectively re-routing a radio frequency signal path from the integral antennas to the auxiliary connectors.

Abstract: A multi-mode radio unit, and more specifically providing a multi-mode radio unit having a 7.2 split mode and a full gNodeB (gNB) mode may be provided. A 7.2 split mode may be executed at a Multi-Mode Radio Unit (MMRU). Next a metric associated with a front-haul link between the MMRU and a Distributed Unit (DU) may be monitored. The metric may be compared to a first threshold, and when the metric is above the first threshold, the MMRU may be caused to switch from the 7.2 split mode to a full gNodeB (gNB) mode.

Abstract: Real-time radio self-calibration may be provided. The self-calibration may begin by sampling a Transmission (TX) signal. An achievable Error Vector Magnitude (EVM) for one or more frames may be determined based on the TX signal. Link budgets for clients may be determined using a TX power and a supported Modulation and Coding Scheme (MCS). A per packet TX power is adjusted based on the achievable EVM and a TX retry rate. The PA linearity of the radio may also be adjusted based on the achievable EVM and the link budget. The client may be regrouped into a new MCS based on the link budget.

Abstract: Disclosed are fluid handling systems and methods for mitigating the effects of pressure drops that occur at the startup of subsea pumps associated with liquid producing reservoirs. The systems and methods are particularly useful in conjunction with subsea pumps used for producing liquids from high-pressure, low permeability hydrocarbon reservoirs. The systems and methods can mitigate damage to reservoir completions and reservoirs caused by high pressure transients downstream of the pump. A choke valve is used to restrict the flow of the liquids prior to the startup of the subsea pump. After the start of the subsea pump, the choke valve is gradually opened while a recirculation valve is gradually closed, and a full bore valve is opened.

Abstract: A transmit system is disclosed herein that includes two receive inputs for receiving input power distributed between two weakly correlated signals. The transmit system further includes a balanced amplifier system for dividing, amplifying, and recombining the two weakly correlated signals and a two antenna array having a first antenna element and a second antenna element for radiating the amplified signals. The transmit system is capable of unicast and multicast transmissions.

Abstract: A method and an apparatus for detecting the start-of-packet in a wireless receiver operating in a packetized wireless network. One method embodiment includes calculating a plurality of start of packet (SOP) indicators, each for one or more of a plurality of receive chains in the receiver; determining one or more linear combinations of respective pluralities of the calculated SOP indicators to form one or more combined SOP indicators; comparing each of a plurality of SOP indicators or combined SOP indicators, including at least one of the combined SOP indicators to a respective threshold to form one or more respective SOP events; and, in the case there is more than one SOP event, determining a logic function of the SOP events to form a SOP decision event.

Abstract: A method for controlling cell size associated with an access point that has a receive sensitivity and an output power. The method includes changing a start of packet threshold and/or a clear channel assessment threshold to vary the cell size of the access point.

Abstract: A configurable antenna system and method of implementing is disclosed, having particular use with a wireless access point of the type used with a wireless local area network. The antenna system includes an antenna arrangement for selectively varying between first and second operational positions. In the first operational position, the antenna arrangement operates in an omni-directional antenna mode. In the second operational position, the antenna arrangement operates in a directional antenna mode. A signal reflecting member is further provided for cooperating with the antenna arrangement in the second operational position, to substantially establish the antenna arrangement in a directional configuration.
