A system for troubleshooting signals in a cellular communications network, and in particular, for determining the cause of distortion or corruption of such signals, includes a robotic or other type of switch. The robotic switch can tap into selected uplink fiber-optic lines and selected downlink fiber-optic lines between radio equipment and radio equipment controllers in a wireless (e.g., cellular) network to extract therefrom the I and Q data. The selected I and Q data, in an optical form, is provided to an optical-to-electrical converter forming part of the system. The system includes an FPGA (Field Programmable Gate Array) or the like, and an analytic computer unit, or web server, and SSD (Solid State Drive) and magnetic disk storage, among other components of the system. The system analyzes the I and Q data provided to it, and determines the cause, or at least narrows the field of possible causes, of impairment to transmitted signals. The system includes a display which provides the troubleshooting information thereon for a user of the system to review, or other form of a report, and may communicate the analytical findings to a remote location over a public or private internet protocol network.

Method and apparatus for the detection of distortion or corruption of cellular communication signals

A vending machine is described that uses digital currency transactions to enable a user to purchase items from their portable computing device. Using a control system in communication with various components of the vending machine and an internet connection for communicating with a remote digital currency system, such as a bitcoin network, a digital currency processing system executes digital currency transactions and stores the resulting digital currency in a transaction storage repository. The control system initiates dispensing of purchased items based on communication from the digital currency processing system.

Methods, systems, and configured storage media are provided for flexible data mirroring. In particular, the invention provides many-to-one data mirroring, including mirroring from local servers running the same or different operating systems and/or file systems at two or more geographically dispersed locations. The invention also provides one-to-many data mirroring, mirroring with or without a dedicated private telecommunications link, and mirroring with or without a dedicated server or another server at the destination(s) to assist the remote mirroring unit(s). In addition, the invention provides flexibility by permitting the use of various combinations of one or more external storage units and/or RAID units to hold mirrored data. Spoofing, SCSI and other bus emulations, and further tools and techniques are used in various embodiments of the invention.

Flexible remote data mirroring

Methods, systems, and configured storage media are provided for flexible data mirroring. In particular, the invention provides local-remote role reversal, implementation of hot standby server status through a 'media not ready' signal, several alternate buffer contents and buffering schemes, transactioning, many-to-one mirroring through use of 'virtual' remote mirroring units, identification of frequently accessed data without application-specific knowledge but based instead on an application's logged and analyzed behavior, and use of the secondary server in a non-authoritative manner.
