A. MC Connector

B. RP-TNC

C. RP-SMA

D. N Connector

E. MMCX

A. One station seems to be streaming video, thus may have reserved significant bandwidth via admission control

B. Contention Free is in place in this network, which may starve some non-QoS stations from access

C. Multipath or excessive collisions seem to be an issue in this area

D. The station that sent this frame is causing a DoS attack by using extended Duration values

E. The AP seems to be too far to provide enough coverage to this area

F. Stations are using null data frames as protection mechanisms to reserve the medium

A. With passive tags, AP transmit gain should be increased to supply extra power for near-field coupling or backscatter modulation from the tag to the AP since the passive tag lacks an internal power source.

B. Active tags transmit directly to the APs and may not require 802.11 authentication and association to pass data traffic to the RTLS engine.

C. When tracking assets with passive RFID tags, some APs should be moved, or additional APs be added, to provide more accurate triangulation and location services.

D. When passive tags are implemented, the AP density should be increased by 25% to make up for the shorter transmit range of passive tags as compared to active tags.

E. Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the tag interrogator to communicate tag information to the infrastructure's location tracking server/database.

F. Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized with the AP for proper location of the tagged asset.

A. Always use paints with metallic dye in them to prevent potential RF propagation impact.

B. Painting APs may void the product manufacturer's warranty.

C. Painting APs always introduces a fire and gas emissions hazard and should be avoided for all indoor APs.

D. Do not paint the notification LEDs on the AP, but configure them to be dim or turned off altogether until troubleshooting is required.

E. Most AP models for indoor environments come in a variety of form factors and colors. Painting is never recommended.

A. mW 10(dBm/10)

B. mW

C. mW

D. mW =

E. mW

F. mW

A. Install APs for client access in the central area and use a mesh backhaul link to connect to the DS.

B. In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as possible to the central area of the warehouse.

C. Position APs along the walls, and equip the APs with Yagi antennas to cover the central area.

D. Equip workers laptops with a directional antenna and install APs less than 328 feet (100m) away from the switch.
