Locust 802.11b Drive Study Test Receiver

Locust™ is a wireless receiver designed specifically for sweeping and optimizing 2.4 GHz Local Area Networks. The instrument measures coverage of direct sequence CDMA networks which operate on the IEEE 802.11b standard allowing the user to determine the AP (Access Point), PER (Packet Error Rate), and RSSI signal levels aiding in locating the hub and access points of neighboring WLANs. Locust™ provides measurements in realtime and also logs data for further post processing analysis. Users may detect and differentiate from narrowband multipath interferences using a drive-test vehicle, GPS antenna and a laptop PC.

The Locust Data Logger is a software application for Windows® 95, 98, NT, ME and 2000 that displays, records and logs all WLAN data received by the Locust™. The software allows complete control of the LOCUST IEEE 802.11b scanner. All data displayed on the Locust LCD is also displayed on the PC screen. Data received by the PC software can be saved in disk files for later replay and conversion. Each measurement screen of the Locust is duplicated by the PC software.
