Antenna Guide for ISR and CGR with Verizon Wireless 4G LTE

LTE Site Survey via SMS: Details

This ISR app will respond to 2 different requests. To use the app, a text message is sent to

the ISR’s LTE interface Mobile Device Number (phone number, the “MSISDN” as seen from

output of “show cell x hardware” command).

The following 2 messages can be sent (as shown below, not case sensitive):

- survey - The ISR will respond with multiple texts including the ISR name, detailed

radio signal info, radio access technology, network information, and GPS coordinates

- survey says - The ISR will respond with a single text including the ISR name, RSSI

and RSRP values, and “Pass” or “Fail”.

Considerations:

- Radio signal strength and quality change dynamically. It is recommended to run the

script multiple times per antenna placement location (a minimum of 3 times). The

antenna locations chosen should “pass” all the surveys.

- It may be helpful to mark the antenna placement spots for each set of survey runs, to

simplify recalling which survey test mapped to each placement.

- To assist in remembering the placement for each survey test, text can be added after

“survey” or “survey says”, and will be ignored by the app. This helps document the

test; for example, placing sticky notes where the antennas were placed with a test

name, and running the surveys with that test name added after the command. See

the last example of the “Sample Installation and Operation” section.

LTE Site Survey via SMS: 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, latest M release recommended (e.g. 15.4(3)M)

3. An active SIM inserted with appropriate IOS configuration, and (optionally)

knowledge of the phone number where text messages are to be sent

4. The Site Survey script loaded onto ISR flash and configured (as shown below)

5. Both main and diversity antennas connected, one via an extension cable. Each LTE

eHWIC, LTE GRWIC, or C819G-4G-V ships with at least one 10’ extension cable.

6. Optional: An external GPS antenna connected to the ISR, with line-of-sight to the sky.
