Product Overview

Vehicular 5-in-1 and 2-in-1 installation and deployment notes

In the section that follows, the 5-in-1 antenna refers to ANT-5-4G2WL2G1-O, and 2-in-1 antenna refers to

ANT-2-WLAN-D-O.

Installation

Users need to provision a 8 x 8" flat mounting surface with a mounting hole on the roof of the vehicle for the

5-in-1 antenna, and a 6 x 6" flat mounting surface with a mounting hole for the 2-in-1 WiFi antenna. Without

a flat mounting surface, the antenna will not meet IP67 standards and may have reduced service life.

Ground plane

Cisco recommends having a 1 foot ground plane under both the 5-in-1 and 2-in-1 antennas. In case of a metal

vehicle roof, the roof itself shall be the ground plane. While Cisco has investigated the effects of ground plane

and no ground plane, wireless performance was certified with the 1 foot ground plane.

Isolation between 5-in-1 and 2-in-1 antennas

Cisco recommends 18" inch spacing between the 5-in-1 and the 2-in-1 antenna centers for optimal isolation.

Cisco recommends routing the 2.4GHz WLAN ports of the IR829 to the 2-in-1 antenna, and the 5GHz ports

to the 5-in-1 antenna to optimize isolation between WiFi 2.4 GHz and cellular 4G LTE. The 5-in-1 antenna

has been fully optimized for WiFI and cellular LTE coexistence and isolation. Connecting the 2.4GHz WiFi

signals to a separate antenna simply allows to user to optimize the antenna isolation further. Both the 5-in-1

and 2-in-1 are dual band WiFi capable and fully support both 2.4 GHz or 5GHz WLAN signals.
