20090185600 | STRENGTHENED FREQUENCY HOPPING COMMUNICATION METHOD AND DEVICE - The invention relates to a frequency hopping communication method in which the data travels over time-variable frequency bearers. A frequency bearer is defined as a subset pair of carriers in a channel of a set of frequency channels (RF). The choice of the frequency bearers is derived from a pseudo-random draw. | 07-23-2009 |
20100177659 | METHOD AND SYSTEM FOR LOCATING INDIVIDUALS INSIDE A BUILDING - A system and a method for locating one or more mobile objects in a detection space is disclosed. The system has a number of detection terminals ( | 07-15-2010 |
20100246476 | METHOD FOR DRIVING SMART ANTENNAS IN A COMMUNICATION NETWORK - A method and device for implementing a smart antenna in a network that uses a deterministic access protocol, one or more mobile stations MS and at least one base station BS, the transmitted data being included in a data frame, wherein it comprises at least the following steps: On entry into the network: | 09-30-2010 |
20110305175 | SELF-CONTAINED ANTENNA DEVICE WITH QUICK AIMING SWITCHING - The present invention includes an autonomous antennal device with fast pointing switching. The antennal device has an electron beam switching antenna, and the device is linkable by a cable to a radioelectric facility. The device includes a calculation unit to determine a direction of pointing of the beam of the antenna on the basis of measurement parameters for the radiofrequency signal processed by the facility, and the parameters are received on a communication interface of the device. The invention applies, for example, to intelligent antennas, sometimes designated by the acronym FESA, which stands for Fast Electronically Steerable Antenna. | 12-15-2011 |

20130064233 | Transceiver Station for Forming a Telecommunications Network Node and Associated Telecommunications Method - A transceiver station is provided for forming a telecommunications network node. The station includes at least two transceiver radio modules and a control module. Each transceiver module is adapted to operate alternatingly as a subscriber station and as a base station, as a function of commands from the control module. The control module is adapted to determine a modification of the state of the network and to dynamically control at least one change in the operation of at least one transceiver module, from subscriber station to base station or vice versa, as a function of at least the determined modification. The control module is adapted so that the number of subscriber stations connected to a base station is at most equal to 1. | 03-14-2013 |
