Software-Defined WAN (ip wan)
le concept découle de la virtualisation des éléments du réseau pour une meilleure gestion et exploitation
l’enjeu : un réseau de meilleur performance (ou plus au moins équivalent), surtout un accès moins cher… que les réseaux privés actuels (MPLS, etc.)
IEEE 802.11 WLAN networks face challenges for end- to-end service performance concerning new mobility applications: real-time interactive communications, analytics and business intelligence.
In dense indoor deployments, co-channel interference is a major issue.
One of Radio Resource Management (RRM) techniques that is used to tackle this issue and maximize transmit opportunity is beamforming.
Beamforming is a major building block of Radio Resource Management (RRM) in WLAN networks that helps mitigate the interference and maximize the transmission opportunity of Access Points (AP) toward Wireless Devices (WD).
In contrast to the related-work In-Path approaches, we propose a novel Out-Of-Path approach to beamforming calibration that is based on concepts from Computer Aided Graphical Design (CAGD) field and now-a-day network design best practices.
The enhancement that the presented solution adds to the beamforming operation time and results’ accuracy is investigated.
Dynamic Radio Resource Management, RRM, is an essential design block in the functional architecture of any Wifi controller in IEEE 802.11 indoor dense enterprise Wlans.
In a mono-channel condition, it helps tackle co-channel interference problem and enrich end-to-end Wifi clients experience.
In this work, we present our dRRM solution: WLCx, and demonstrate its performance over related-work and vendor approaches.
