摘要:
An ad-hoc, peer-to-peer radio access system for cellular communications systems using time division duplex as a way of maximizing the bits/hz/km2 for cellular systems. The network architecture of the ad-hoc system allows the radio access to be integrated with the fixed components of a conventional cellular system, PSTN or ISP. The objective is to make the system of the invention transparent to the features and services provided by the external network. The advantages of such a system to a cellular operator are that significantly less infrastructure is required, and that the RF spectrum is more efficiently utilized resulting in much lower building and operating costs. The system architecture is comprised of remote terminals, routers, gateways, and at least one gateway controller that interfaces the ad-hoc system to a cellular network system. The ad-hoc system of the invention allows for both voice and data transmissions and receptions.

Spectrum that overlaps in time, geography and frequency is allocated to more than one radio network. The networks share the spectrum by employing spectrum sharing in accordance with spectrum sharing control data to avoid collisions between the transmissions of the networks.
摘要:
Spectrum that will become venue-protected in the future is made available to radio devices by a central control system with which the radio devices requests spectrum access information for use in wireless communication. The central control system establishes a re-request time duration specified in an amount of time that will elapsed at or before the spectrum becomes protected. The elapsing of the re-request duration serves as a command to the radio device to transmit a new channel request to the central control system
摘要:
Systems and methods of providing network access information from one or more servers to a wireless device. The wireless device acquires information from the servers about available networks at a current location of the wireless device. The network information is based on a plurality of device parameters, network parameters and regulatory requirements that govern the operation of the wireless device. In addition, the wireless device may assess the acquired information for suitability for communications to be carried out by the wireless device.
摘要:
Disclosed are techniques for managing situations where spectrum use by one party is preempted by spectrum needs of another party. A revocation may be sent from a spectrum management system to secondary radio systems that are impacted by the presence of priority radio system. Remedial action may be taken if an acknowledgement of the revocation message is not received from a secondary radio system. Also, the secondary radio systems may transmit keep-alive messages to monitor operation of the communication pathway for the revocation messages.

摘要:
A registration system for secondary radio systems that use spectrum that is interleaved with spectrum used by primary radio systems may include an interface to communicate with the secondary radio systems over a network. The registration system also may receive a registration request from a requesting one of the secondary radio systems and generate a spectrum certificate for the requesting secondary radio system. The spectrum certificate may contain a channel map identifying available channels that may be used for wireless communications activity of the requesting secondary radio system and may contain, for each available channel, a guidance indicator that identifies relative channel desirability to the requesting secondary radio system.
摘要:
In systems and methods for analyzing spectrum, a radio system may sample spectrum and transmit the sample to a remote spectrum analysis system. The remote spectrum analysis system analyzes the sample to determine if an incumbent radio system or radar is present and returns analysis results to the radio system. The remote spectrum analysis system may use information acquired from other sources, such as a knowledge base of devices that operate in the vicinity of the radio system to assist in analyzing the spectrum sample.

摘要:
The present disclosure describes systems and methods that facilitate the transfer rights associated with spectrum between parties. Access to spectrum for wireless communications may be transferred from a spectrum holder to a spectrum user while minimizing their role in submitting regulatory agency compliance filings. As a result, parties may transfer spectrum with relative ease, with faster transaction time and lower expense. This leads to more efficient use of the spectrum.
