Chapter 8 About Connected Grid Antennas
Router Antennas Overview
WiFi Antenna
The Connected Grid 4GE LTE WiFi antenna kit (optional) includes the following items:
•
4G LTE indoor swivel-mount antenna (see
Figure 8-3
)
•
Male QMA connector adapter, to connect the antenna to the router WiFi antenna port
The WiFi antenna provides connectivity to the router internal short-range access point.
The short-range access point enables a WiFi link so users can connect to the router from anywhere within
WiFi range. For example, a technician can check the status of the router from outside the substation or
utility cabinet by connecting to the router over the WiFi link.

Connected Grid Module Antennas
In addition to the two fixed antennas (GPS and WiFi), the router supports additional antennas that
provide connectivity to the Connected Grid modules installed in the router.
The router supports up to two Cisco Connected Grid modules
.
Each module requires one antenna or two
antennas (one main antenna and one diversity antenna). The total number of antennas installed with the
router depends on:
•
Number of modules installed in the router.
•
Module types that are installed in the router
