LABORATORIOS

Infrastructure Mode Throughput Analysis

Pure mode throughput (802.11b vs. 802.11g vs. 802.11a vs. 802.11n)
Mixed mode throughput
Adjacent and co-channel interference
Understanding the "speeds and feeds" of all Wi-Fi technologies is crucial to optimizing WLAN installations, applications, and good network design. This lab demonstrates the varying throughputs for Wi-Fi connectivity standards by using FTP to transfer large files from client devices to servers. You will see and compare actual throughputs of each different technology, and the impact of using mixed technologies within the same radio spectrum.
These comparisons are done using four different network architectures:
Autonomous APs and client devices in pure mode
Autonomous APs and client devices in mixed mode
WLAN Controller with Lightweight APs and client devices in pure mode
WLAN Controller with Lightweight APs and client devices in mixed mode
Co-channel and adjacent channel interference affects throughput of Wi-Fi systems dramatically. Proper network design eliminates most channel interference. The affects of channel interference are demonstrated in this exercise.
Wireless LAN Security.
Security mechanisms for WLANs exists such as VPNs (PPTP, IPSec) and secure applications (FTP/SSH, HTTPS, POP3/SSL). This lab exercise will demonstrate VPN technology using Microsoft's PPTP/MS-CHAPv2/MPPE-128 (RC4).
Site Surveying
Two specific classes of site survey methodology exist and are used in the WLAN market today:
Manual site surveys (often called the "walkabout")
Predictive analysis (often hailed as "the site survey method of the future")
Within each class exist two distinct categories. Manual site surveying can be categorized as either active mode or passive mode, and one or both modes can be used at any given time.
Predictive analysis software tools are based on a mathematical model of a facility blueprint and can be performed in two distinct ways. First, importing and AutoCAD (vectorized graphic) drawing allows the predictive analysis software tool to understand detailed complex layers of a facility's construction, including wall attenuation, attenuation between floors, and channel interference. Second, importing of raster graphics, such as .jpg or .bmp, allows for faster but less accurate modeling.
Neither methodology is 100% accurate, since each has its own individual weaknesses. Used together, the surveyor can create a more complete RF snapshot of any facility.
