문제2
After preparing a LAN Planner predictive site survey to visualize data rate coverage for an upgrade to an existing 802.11b/g WLAN, you are informed that the customer will also need to continue to provide support for 802.11b bar code scanners throughout the facility. Using LANPlanner, you predict that with the current placement of APs, a maximum 802.llg data rate of 18 Mbps will be available in the locations indicated by arrows on the heatmap shown in Exhibit A.4.2.01 at the bottom. This is due to dense wall construction materials and low AP output power settings. Using the raw values shown in Chart A in the exhibit, and ignoring any additional fade margins or fudge factors, what would be the maximum, possible 802.11b connection rate at the indicated locations?

문제3
You are designing a new 802.11 installation that will be built on an IEEE 802.3 10/100/1000 BaseT-backbone infrastructure. All IEEE 802.11n access points and VoIP phones will be IEEE 802.3 Power over Ethernet (PoE) powered devices. The 802.11n access points will utilize dual band 3X3 MIMO and require 802.3at PoE. Which is a true statement regarding a WLAN deployment of this nature?

문제4
You have been working on the design specification for a new WiNG 5 VVLAN for a new customer. The client needs wireless internet connectivity as well as voice over IP (VoIP) in two key auditoriums of their sports center. Your team has just created a LANPIanner report and the design calls for 11 APs. The customer had identified 2 client locations (Location A and Location B) that he would like to discuss with you.
If the necessary SIR for a customer application is 20db at 2.4 GHz, which of the following is TRUE? Use the relevant SIR map in the LANPlanner - Sports Center exhibit at the bottom.
