In this post, we present the work entirely accessible at link: Bézier Curves Based Novel Calibration Technique of Beamformers in IEEE 802.11 WLAN Networks, about a new way of doing beamforming in the wlan unified (WLC-based) network. Let’s recall that beamforming is the mean by which an access point (AP) concentrate the electromagnetic energy toward…
In this blog, we’ll discuss in detail the operation of HSRP one of the most known FHRP (First Hop Routing Protocols) protocols proposed by Cisco to help secure (in terms of redundancy) the gateway (for hosts or servers) within a LAN. The objective is simple: configure one gateway address and provision as many real routers…...

In this blog, we talk about the general idea about using and IDS or IPS. let’s recall that IDS/IPS stands for intrusion detection and prevention systems. We give examples of implementations of vendors and leaders of the market. Scope of an IDS/IPS Let’s start from a basic setup: clients that try to access ressources on…
This post is descriptive of our work on RRM or radio resource management in WLAN (Wireless LAN) and especially on the operation of beamforming, available here : Bézier Curves-Based Novel Out-of-Path Beamforming Calibration Technique in IEEE 802.11 WLAN Networks First of all what is beamforming Beamforming is a major building block of Radio Resource Management…
In this blog let’s try to connect to a home network from outside (internet) in a secure manner using SSL. NAT and PAT NAT and PAT is what allowed local IP addresses translation or mapping to some routable public IP address (over the internet). This mapping can be one to one (NAT) or many to…
