A method for controlling data transmission within a telecommunications network involves providing interconnections to both a core network and to at least one user device via a base station. A configurable network is defined interconnecting the at least one core network and the base station. A first network slice is selected responsive to use of the configurable network by a first application. A second network slice is selected responsive to use of the configurable network by a second application. Data transmission are provided between the core network and the base station over the configurable network based on the selected first or second network slice.

A wireless device driving method includes hiding a header emulated with a second protocol in a payload of a packet defined with a first protocol and transmitting the emulated header at a transmission side, receiving the emulated header and an ambient signal at a reception side, and decoding the ambient signal according to the second protocol to obtain a bit sequence.

Novel tools and techniques are provided for implementing a novel integrated programmable gain amplifier (“PGA”) and protection circuit. In various embodiments, a circuit is provided that comprises: a PGA, an analog-to-digital converter (“ADC”), and a protection circuit all disposed on the same semiconductor chip. The PGA is configured to receive as input a wireless signal received from an antenna and to output, at its output, an amplified wireless signal based on the wireless signal being amplified by a programmable gain amount. The protection circuit is configured to, in response to detecting a spike in gain at the output of the PGA that exceeds a threshold amplitude, control a decrease in the programmable gain amount to cause a resultant signal at the output of the PGA to be below the threshold amplitude. A normally-open switch may also be added at differential outputs of the PGA to further clamp PGA output.

Applications of CI processing to ad-hoc and peer-to-peer networking significantly improve throughput, network capacity, range, power efficiency, and spectral efficiency. CI-based subscriber units perform network-control functions to optimize network performance relative to channel conditions, network loads, and subscriber services. CI codes are used to identify and address network transmissions. Channel characteristics of communication links are employed to encode, address, and authenticate network transmissions. CI transceivers used as relays and routers employ unique characteristics of transmission paths to code and decode network transmissions. A central processor is adapted to perform array processing with signals received from, and transmitted by, a plurality of subscriber units in a wireless network.

A communication system is described. The communication system includes a number of nodes which frequency hop without coordination from a frequency table. To establish communication, the nodes scan across a band for one or more signals of interest. The signals of interest include one or more of a synchronization signal, a control signal, and a traffic signal. When transmitting the signals of interest, the nodes determine one or more characteristic for the signal, such as a channel, based on a spectral occupancy of interferers in the band.

The disclosed invention includes methods for linking individual software-defined radios (SDR) into a cohesive network of SDRs capable of recording a sample of radiofrequency (RF) signals emitted in an RF environment. Individual SDRs communicate with an IP network, and host a linking application that executes the recording. A user identifies a lead SDR from among the SDRs, and uses the lead SDR to task participating SDRs with reference to a clock source.

Such systems can employ a network of RF sensors that can coordinate in response to communication with a computer to perform any such detection and/or determination using trained models executed onboard the RF sensors and/or the computer. RF signals may have unique characteristics when received at one or more RF sensors that may be detected using trained models described herein, even in high noise or non-line of sight (LOS) environments and with low cost, low resolution RF receiver hardware.
