VMM6300 Trunk Mounting 
2.5.1 Deployment Considerations 
When deploying the VMM6300 consider the following: 
•  The antenna should be a minimum of 30 inches from any nearby metal poles to avoid 
distortion of the RF pattern.   
•  The antenna must have a separation distance of at least 2 meters from the body of all 
persons and must not be co-located or operating in conjunction with any other antenna or 
transmitter.   
•  Users and installers must be provided with antenna installation and transmitter operating 
conditions to satisfy RF exposure compliance.  
•  Typically, Vehicle Mounted Modems are distributed within a network and are used as 
subscriber devices. A rule of thumb is to deploy 2-3 hop networks to optimize range, latency, 
and throughput to subscriber devices.  
•  The VMM6300 installation location must provide applicable DC power for the device. 
• It is 
required
 that the VMM chassis be grounded to minimize the possibility of ESD 
(electrostatic discharge) induced damage.  
 
2.5.1.1 Deployment 
Tips 
Locate the antenna to minimize multipath:  
- Minimize interference from nearby transmitters 
- Maximize chance of a direct line of sight connection to other devices. 
- Mount the supplied antenna vertically 
 
2.6  Testing the Device Installation 
Verify the operation of the VMM6300 using the following procedure:  
 
1.  Apply power to the VMM6300 – power reset button will be illuminated to red.
