Most LTE specifications recommend (or even require) the use of dual antennas for a MIMO configuration.  Many antennas include a MIMO configuration in a single antenna housing, which can be confirmed if there are two cellular coax connections running from the housing.  A single-housing MIMO antenna would also require the use of dual coax extension cables. If you select a non-MIMO antenna it is recommended that two separate antennas are used, though this configuration doubles the cost of the antenna unit itself as well as the coax extension cabling.  It is typically recommended to include some “separation” when mounting antennas to prevent interference (the antenna manufacturer may provide a recommendation but 18 to 24 inches should be sufficient).

Please consider the following when mounting your PoE LTE Router or third-party antennas:

1. Maximize Ethernet vs. coax extensions (e.g. inside vs. outside the building)
2. Avoid mounting inside metal enclosures or even near large metal objects
3. Within reason, maximize the distance from any other electronic equipment
4. Mount the device near an exterior wall or window (or run the antenna outdoors)
5. If possible, mount to the ceiling vs. the wall (the wall can introduce interference)
6. Generally mounting higher is better (but consider future serviceability)
7. Try to always use a MIMO antenna solution for the best results / RF performance

Accelerated has tested the following antenna solutions for performance and compatibility purposes.  Please use this information as a reference to assist in determining the right antenna solution for your specific use case. It is important to test the antennas you select in your specific application environment (meaning your deployment site).

Please note that a booster, repeater, or amplifier may be another strategy to improve RF sensitivity.  However, these technologies can also introduce issues because they may “amplify” bad signal.  The focus of this chapter is on antennas but more information on boosters can be found on-line.
