Mounting On A Wall, Table, Or Other Flat Surface - Cisco IR809 Installation Instructions Manual

Mounting on a Wall, Table, or Other Flat Surface

• Sierra Wireless MC73xx modem series supports MIMO on LTE. WCDMA UMTS HSPA DC-HSPA+
• The IR809 must be installed with 2 antennas (Main & Aux) to guarantee the best performance level.
• In case of 3G UMTS, a solo antenna would not be able to switch to the diversity port.
Step 1 Manually screw the antenna tight to the TNC connectors on the back of the router.
Step 2
Orient the antennas. For optimum wireless performance, antennas should be generally perpendicular to each other.

hardware or to follow the correct procedures could result in a hazardous situation to people and damage
to the system. Statement 378
Note When mounted from the back using #10 screws, the torque is 22-30 in-lbs. When mounted from front
using #6 screws the torque is 8.3-11 in-lbs.

is diversity only, without MIMO.
Using a single antenna may impact downlink performance by a minimum of 3dB, and can be much more
(10-20dB) due to multipath fading (destructive interference between direct and reflected radio waves).
