Manufactory commercial intersystem communication devices of networks, systems, complexes and electro

The present invention is directed toward the field of replicating information from a host system where the information is normally stored to a mobile data communication device. The mobile data communication device is preferably coupled to the host system via a wireless network and one or more landline networks. Due to the bandwidth limitations of wireless networks, only a part of a user-selected data item is generally redirected to the user's mobile device, with the user given the option of then retrieving the entire data item or some other part of the data item from the host system. In these types of systems and methods, when replication of the warehoused data items to the mobile device is desired, the user typically places the mobile device in an interface cradle that is electrically connected to the host system via some form of local, dedicated communication, such as a serial cable or an infrared or other type of wireless link. Software executing on the mobile data communication device then transmits commands via the local communications link to the host system to cause the host to begin transmitting the user's data items for storage in a memory bank of the mobile device. Thus, the two systems host and mobile maintain the same data items only after a user-initiated synchronization sequence.

This application claims the benefit of and priority to U. Provisional Patent Application No. Satellite radiotelephone communications systems and methods are widely used for radiotelephone communications. A satellite radiotelephone communications system or method may utilize a single satellite antenna pattern beam or cell covering an entire service region served by the system.

Alternatively or in combination with the above, in cellular satellite radiotelephone communications systems and methods, multiple satellite antenna patterns beams or cells are provided, each of which can serve a substantially distinct service region in an overall service region, to collectively provide service to the overall service region.

Thus, a cellular architecture similar to that used in conventional terrestrial cellular radiotelephone systems and methods can be implemented in cellular satellite-based systems and methods. The satellite typically communicates with radiotelephones over a bidirectional communications pathway, with radiotelephone communications signals being communicated from the satellite to the radiotelephone over a downlink or forward link also referred to as forward service link , and from the radiotelephone to the satellite over an uplink or return link also referred to as return service link.

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application, illustrate certain embodiment s of the invention.

In the drawings:. Embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Like numbers refer to like elements throughout. It will be understood that, although the terms first, second, etc. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of the present invention.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Unless otherwise defined, all terms including technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms used herein should be interpreted as having a meaning that is consistent with their meaning in the context of this specification and the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Any suitable computer readable medium may be utilized including hard disks, CD ROMs, optical storage devices, a transmission media such as those supporting the Internet or an intranet, or magnetic storage devices. Although some of the diagrams include arrows on communication paths to show a primary direction of communication, it is to be understood that communication may occur in the opposite direction to the depicted arrows.

Some embodiments of the present invention may arise from realization that a transceiver of an Independent Communications System ICS , such as, for example, a satellite or user terminal of a satellite communications systems, may operate in an adjacent or proximate frequency band to a frequency band used by one or more Terrestrial Cellular Systems TCS. For example, a user device of an ICS may be physically proximate to e.

In some embodiments of the present invention, systems and methods are provided that may reduce or minimize inter-system interference from a Terrestrial Cellular System TCS to an Independent Communications System ICS that may be operating in a frequency band that is proximate to a frequency band used by the TCS. The technique also may reduce or minimize the intra-system interference.

Estimates of array covariance matrices may be derived from the received vectors of an ICS signal s and TCS signal s , respectively. The frequency transformed ICS covariance matrix or spatial signature, along with the TCS covariance matrix or a spatial signature, may be exploited to form a composite covariance matrix or spatial signature matrix that contains spatial information associated with both TCS user terminals and ICS transceivers.

As shown in FIG. The space-based component may also be configured to receive wireless communications from a plurality of wireless terminals, such as wireless terminal a in the satellite cell , over one or more satellite return service link uplink frequencies f U. A cellular satellite communications system may include a terrestrial communications system TCS including at least one Base Transceiver System BTS , which may include an antenna a and an electronics system b.

The BTS is configured to receive wireless communications signals from, for example, at least one wireless terminal b via a communication link As noted above, a user terminal a of the cellular satellite communications system may communicate with the SBC using an uplink frequency f U within the satellite frequency band.

Thus, as illustrated in FIG. This interference may generally be strongest when the transmitted signal uses the same carrier frequency as the cell in question e. Even with spatial separation, however, interference may impair the signal from the first wireless terminal a.

Still referring to FIG. The satellite gateway communicates with the space-based component over a satellite feeder link The satellite gateway may also be configured to communicate with ancillary terrestrial components in the ancillary terrestrial network, generally over a terrestrial link The satellite gateway may communicate with the BTS via a communications link , which may be used to coordinate communications of the BTS and the SBC in order to reduce interference between the ancillary terrestrial network and the SBC The satellite may be part of a separate satellite communications system i.

Accordingly, the use of satellite frequencies may not be coordinated between the external satellite and the BTS For example, the external satellite may be a satellite in the existing Inmarsat satellite communications system, which includes eleven geostationary communications satellites, and the ICS user terminal may include, for example, a fixed or mobile satellite terminal.

Socio-Technical Perspectives on Smart Working: Creating Meaningful and Sustainable Systems

This application is based up and claims the benefit of priority for prior Non-provisional patent application Ser. Mobile data communications can enable a wide variety of services. However, mobile data providers, such as cell phone providers, mobile virtual network operators MVNO's , or mobile virtual network enablers MVNE's , have processes—for example, provisioning processes—that are tailored for standard cell phone services. In particular, an equipment provider or another type of customer for mobile data communications may desire to provide equipment enabled to use mobile data communications. In order to test that the equipment is fully functional with a mobile data communications provider, the equipment provider in the current environment most likely will be required to completely activate the equipment i. When the testing is complete, the service plan will likely be terminated, and the final customer will be required to reactivate the service plan with customer billing. It would be beneficial if the mobile data providers' processes—for example, provisioning—could be tailored for the needs of customers of mobile data communications.

Internetworking is combined of 2 words, inter and networking which implies an association between totally different nodes or segments. This connection area unit is established through intercessor devices akin to routers or gateway. The first term for associate degree internetwork was catenet. This interconnection is often among or between public, private, commercial, industrial, or governmental networks. Thus, associate degree internetwork could be an assortment of individual networks, connected by intermediate networking devices, that functions as one giant network. Internetworking refers to the trade, products, and procedures that meet the challenge of making and administering internetworks. Internetworking was designed to resolve the matter of delivering a packet of information through many links.

Industrial Internet of Things IIoT applications, featured with data-centric innovations, are leveraging the observability, control, and analytics, as well as the safety of industrial operations. The wireless system design for IIoT applications is inherently a joint effort between operational technology OT engineers, information technology IT system architects, and wireless network planners. In this paper, we propose a new reference framework for the wireless system design in IIoT use cases. The framework presents a generic design process and identifies the key questions and tools of individual procedures. Specifically, we extract impact factors from distinct domains including industrial operations and environments, data service dynamics, and the IT infrastructure. We then map these factors into function clusters and discuss their respective impact on performance metrics and resource utilization strategies. Finally, discussions take place in four exemplary IIoT applications where we use the framework to identify the wireless network issues and deployment features in the continuous process monitoring, discrete system control, mobile applications, and spectrum harmonization, respectively. The goals of this work are twofold: 1 to assist OT engineers to better recognize wireless communication demands and challenges in their plants, 2 to help industrial IT specialists to come up with operative and efficient end-to-end wireless solutions to meet demanding needs in factory environments. The volume and categories of industrial data exhibit a remarkable growth.

In the environment of the automation of industrial processes, the communication between the devices that intervene in the control of these systems, is a key issue to allow not only a correct operation, but also the supervision and control of these processes. The communications between devices are carried out through the use of different industrial communications protocols. A communication protocol is a set of rules that allows the transfer and exchange of data between the devices to communicate. As technological development in the field of electronics has progressed, automated control of industrial processes has been imposed on traditional production methods. In the early stages of the introduction of this technology in the industry, automation was limited to local control of certain machines or production lines, leading to automatic systems isolated from each other, which could not share information to optimize the development of work on a larger scale.
