In your company's WLAN, you expect to have a mixed client PHY environment and plan to use protection mechanisms. The protection mechanism used by your client devices is configurable.
What is the best protection mechanism for backward compatibility of 802.11n devices with 802.11b devices?
Response:
In a manufacturing facility with highly reflective materials, you are planning an upgrade to your existing
802.11b WLAN implementation. You have
chosen a dual- band 802.11n infrastructure product for this purpose. Your client applications include:
Handheld scanners for inventory management
Toughbooks (laptops) mounted on forklifts for inventory and workflow management VoWiFi phones used by select employees throughout the facility You are evaluating all of the 802.11n enhancements and determining which features to enable for your environment and applications.
In this scenario, what 802.11n enhancement typically should NOT be enabled on the 2.4 GHz radio of the new APs?
Looking at a client radio specification sheet that states Receive Sensitivity of 82 dBm @ 18 Mbps would mean:
Response:
What single tool, by design can be used to verify channel selection, encryption in use and number of APs above a specified signal threshold in a given location during deployment?
During a post-validation survey, you find an area lacking any detectable Wi-Fi signal at all It is located behind an elevator shaft What is a common solution to this problem?
