EUT Description
Model: B-DB-AC, Bullet
Description: Dual Band Networking Device
Firmware: N/A
Software: N/A
Serial Number: N/A
Additional Information: The Bullet AC (Model: B-DB-AC) is a dual band networking device that is
powered over ethernet (passive POE, 24V) and provides an N-type antenna connection. It features dual-
band AC mode operation in 5GHz and 2.4GHz bands, and a dedicated 2.4 GHz WiFi management radio
for convenient device setup.

EUT Operation during Tests
Radio testing has been done conducted and radiated with controlling the device for continuous
modulation transmission on low, middle and high channels with client’s provided commands through
telnet.

Note: Power is brought down one by one for other antennas mathematically so the highest EIRP for 4dBi
antenna would be the same for other antennas as well.
