Antenna Guide for ISR and CGR with Verizon Wireless 4G LTE
Requirements
1.
ISR G2 with an LTE eHWIC or an 819 series ISR with embedded LTE
2.
A minimum IOS level of 15.3(3)M2
3.
An active SIM inserted with appropriate IOS configuration, and (optionally) knowledge of the phone number
where text messages are to be sent
4.
An external GPS antenna connected to the ISR, with line-of-sight to the sky.
5.
gps_geofence.tcl script loaded onto ISR and properly configured
Installation
1) Insert an external GPS antenna connected to the ISR. An 819-4G is shown below.
2) Enable GPS
From IOS configuration mode:
controller Cellular <number>
(“number” from running config or “show ip int brief”)
lte gps mode standalone
lte gps nmea ip
(note that for ISRs using eHWIC/GRWIC, the “ip” variable is omitted)
3) Download the gps_geofence.tcl script from
https://supportforums.cisco.com/document/12150821/geo-fence
4) Copy gps_geofence.tcl script onto the ISR flash via USB drive, TFTP, FTP, etc.
5) (optional) Configure the following variables as needed:
-
_homelongitude x y z east|west
(x y z coordinates are degrees minutes seconds and either east or west, as
found via the ISR “show cell x gps” command output
-
_homelatitude x y z north|south
(x y z coordinates are degrees minutes seconds and either north or south,
as found via the ISR “show cell x gps” command output
Both of the above should be included, or neither included. If included, this will be the “home location”. If not
included, the script will set the “home location” as the location seen the first (or next) period the script runs. If
the lines are present then removed, the next time the script runs it will reset the “home location” and keep this
value. To reset it, reinsert the definitions.
