Abstract

L'invention concerne des systèmes d'antennes répartis à base de fibres optiques qui prennent en charge des configurations d'antennes et des communications à entrées et sorties multiples (MIMO). Les modes de réalisation ci-décrits comprennent un système réparti d'antennes à base de fibres optiques qui peut être configuré de façon souple pour prendre en charge ou non des configurations de communications MIMO. Dans un mode de réalisation, des premier et deuxième trajets de communication MIMO sont partagés sur la même fibre optique par une conversion de fréquence pour éviter les problèmes d'interférences, le deuxième trajet de communication étant mis en place pour relier une unité d'extension distante à une unité d'antenne distante. Dans un autre mode de réalisation, les systèmes répartis d'antennes à base de fibres optiques peuvent être configurés pour permettre la mise en place de configurations de communication MIMO à l'aide de composants existants. La capacité existante de composants du système est employée pour créer des deuxièmes trajets de communication pour des configurations MIMO, réduisant ainsi la capacité globale mais permettant de se passer de composants de conversion de fréquence et d'unités d'extension distantes.
