A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.

Secure data parser method and system

Aspects of the subject disclosure may include, for example, receiving, by a feed point of a dielectric antenna, electromagnetic waves from a dielectric core coupled to the feed point without an electrical return path, where at least a portion of the dielectric antenna comprises a conductive surface, directing, by the feed point, the electromagnetic waves to a proximal portion of the dielectric antenna, and radiating, via an aperture of the dielectric antenna, a wireless signal responsive to the electromagnetic waves being received at the aperture. Other embodiments are disclosed.

Method and apparatus for coupling an antenna to a device

A distributed antenna and backhaul system provide network connectivity for a small cell deployment. Rather than building new structures, and installing additional fiber and cable, embodiments described herein disclose using high-bandwidth, millimeter-wave communications and existing power line infrastructure. Above ground backhaul connections via power lines and line-of-sight millimeter-wave band signals as well as underground backhaul connections via buried electrical conduits can provide connectivity to the distributed base stations. An overhead millimeter-wave system can also be used to provide backhaul connectivity. Modules can be placed onto existing infrastructure, such as streetlights and utility poles, and the modules can contain base stations and antennas to transmit the millimeter-waves to and from other modules.

Backhaul link for distributed antenna system

A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

Remote distributed antenna system

Aspects of the subject disclosure may include, for example, a device that facilitates transmitting electromagnetic waves along a surface of a wire that facilitates delivery of electric energy to devices, and sensing a condition that is adverse to the electromagnetic waves propagating along the surface of the wire. Other embodiments are disclosed.

Method and apparatus for sensing a condition in a transmission medium of electromagnetic waves

A first radio station receives a message in a first frequency band from a second radio station and passes the message to a third radio station in a second frequency band, where the width of the first frequency band differs from the width of the second frequency band. The modulation of the data in the message is maintained unchanged and the first radio station is not required to perform decoding of the message.

Radio Communication with a Repeater

The invention relates to a method for transferring data (D) via an interface (VA, BS, A) of a communication system (GSM/A) between at least one emitter (MS1) and at least one receiver (MS2), at least part of the data (CD) being transferred in a secure manner. The aim of the invention is to transfer the data in an efficient, but nevertheless secure, manner. To this end, the part of the data (CD) to be transferred in a secure manner is transferred via a secure interface (VA, GSM, A) and the remaining part of the data (ND) is transferred via an interface (VB, WLAN, B) which is not especially secure, especially another communication system. Basic data for the reproduction of a basic information message can be selected and/or transferred as the data (CD) to be transferred in a secure manner. A code for decoding coded data (ND) can also be transferred as the data (CD) to be transferred in a secure manner. The rest of the data (ND) is then transferred as data (ND) which is encoded by said code (CD). The secure interface (VA, GSM, A) is embodied in a secure manner in terms of availability and/or in terms of data security.

Method and data processing device for transferring data via various interfaces

A data processing unit (DIV) sends data (D) between a transmitter (MS1) and receivers (MS2) with a coded part (ND) sent over a normal local area network radio interface (VB) and a code (C) to unlock these data sent (CD) over a secure cellular radio interface (VA).

Data processing unit splits data and code between cellular and local networks

The aim of the invention is to adapt a transmission data rate to an existing transmission channel. To this end, the invention provides that the transmitter power and/or the coding method is/are selected in such a way that a maximally possible transmission data rate or minimal transmitter power can be used according to the transmission quality of the transmission channel.
