IPC: H04B10/12
Filed: 1998-06-29
Abstract: A wireless communication system which is reconfigurable to accommodate varying traffic density is provided by using a flexible optical interface between a base station controller and several base stations. Communication between the base station controller and the base stations is provided over an optical fiber. The fiber carries several communication channels in both directions using wavelength multiplexing. The bandwidth between the base station controller and a particular base station is varied by increasing or decreasing the number of wavelengths used to communicate with the base station. Varying the bandwidth provides the ability to adjust the capacity to carry voice and/or data between the base station controller and the base station. As a result the number of radio frequency carrier frequencies assigned to a base station can be varied to support varying radio frequency traffic density throughout the wireless network.

Title: Method for making cards and cards obtained by this method
Inventor: DROZ FRANCOIS
IPC: B29C63/02
Filed: 1996-11-12
Abstract: The invention concerns a method for making smart cards by rolling. A first synthetic sheet (1) is first smoothed by hot pressing against a first smoothing plate (4). Likewise a second synthetic sheet (2) is smoothed against a second smoothing plate (5). Without being unstuck from their smoothing plates, these two sheets are rolled with other layers (3, 6, 7), said synthetic sheets (1, 2) serving as external layers. One of the smoothing plates may comprise a three-dimensional pattern to be relief printed on the synthetic sheet. The rolling is carried out by cold pressing the different layers (1, 6, 3, 7, 2) which the laminated card comprises between the two smoothing plates (4, 5). After being rolled, different cards with adapted dimensions can be cut out from the laminated sheets. The invention is advantageous in that the same plates (4, 5) are used for the hot pressing and the cold rolling. The external surface of the synthetic sheets (1, 2) thus remains protected between these two operations and the cards have better inherent flatness.
