• Sierra Wireless WP7xxx modem series supports SIMO on LTE. WCDMA UMTS HSPA DC-HSPA+
is diversity only, without SIMO.
• The IR807 must be installed with 2 antennas (Main & Aux) to guarantee the best performance level.
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).
• In case of 3G UMTS, a solo antenna would not be able to switch to the diversity port.
Mounting on a Wall, Table, or Other Flat Surface
The Cisco IR807 can be mounted in a vertical or horizontal orientation. It can be mounted to a wall or other
flat surface, and can also be mounted to a DIN rail.
TIP
: When choosing a location for wall-mounting the router, consider cable limitations and wall structure.
WARNING:
Read the wall-mounting instructions carefully before beginning installation. Failure to use the
correct hardware or to follow the correct procedures could result in a hazardous situation to people and damage
to the system. Statement 378
