Title (EN) SECONDARY CHANNEL FOR RADIO FREQUENCY COMMUNICATIONS
(FR) CANAL SECONDAIRE POUR COMMUNICATIONS A FREQUENCE RADIOELECTRIQUE
Abstract:
(EN) A system for radio frequency communications between a first unit and a second unit. The communications are conducted over a first frequency and a second frequency. The first unit and the second unit each transmit and receive communications, including first, second, third and fourth information, in bursts over select time intervals, including a first time interval and a second time interval. The system includes communication between a plurality of wireless handset units and a base unit utilizing an FDD/TDD format.
(FR) L'invention concerne un système de communications à fréquence radioélectrique entre une première unité et une seconde unité. Les communications s'effectuent à une première fréquence et à une seconde fréquence. Chacune desdites première et seconde unité transmet et reçoit des communications comprenant des première, deuxième, troisième et quatrième informations, arrivant par rafales pendant certains intervalles de temps, notamment un premier intervalle de temps et un second intervalle de temps. Ce système consiste à faire communiquer plusieurs combinés sans fil et un bloc de base utilisant un format DRF/DRT.
