Abstract: A network device may be configured to iteratively modify an initial tone map for each communication region of a powerline cycle to minimize the time before application data can be transmitted. A first network device estimates an initial tone map for each communication region based, at least in part, on sounding messages received from a second network device. The first network device determines whether to estimate a modified tone map for the first communication region based on at least one performance measurement associated with a data packet generated using the initial tone map for the first communication region. If so, the second network device retransmits the sounding messages in the first communication region that will be used to modify the initial tone map for the first communication region, and the second network device continues to transmit the data packets using the initial tone maps in the remaining communication regions.

Abstract: Embodiments provide WiFi and LTE tailored transceiver radio frequency (RF) filtering techniques and configurations to enable coexistence between WiFi and LTE transceivers operating in close proximity. In particular, embodiments provide filtering techniques to reject emissions from LTE into WiFi, and vice versa. The filtering techniques eliminate the need for additional isolation between LTE and WiFi antennas (approximately 50 dB), which is beyond what is achievable in practice. Embodiments can be tailored according to different use cases of the WiFi and LTE transceivers (e.g., fixed CPE, portable router, smart phone with tethering).

Management software acquires configuration information of a storage system (computer system) in two stages. In a first stage, the management software acquires only basic information of resources (identifiers of resources, the number of resources, and relationship between the resources) included in storage subsystems, host computers, switches, hubs, and the like. The management software determines a range and timing of acquiring detailed configuration information and necessity of holding the detailed configuration information based on the acquired basic information. In a second stage, the management software acquires the detailed configuration information of an appropriate range at appropriate timing. The management software always holds the basic information, but holds the detailed information only necessary to hold.
