–101 or less dBm = Unacceptable (running LED),
•
–100 to –91 dBm = Weak (1 LED),
•
–90 to –81 dBm = Moderate (2 LED),
•
–80 to –75 dBm = Good (3 LED),
•
–74 or better dBm = Excellent (4 LED),
•
0 is not known or not detectable (running LED).
Antenna placement
Placement can drastically increase the signal strength of a cellular connection. Often times, just moving the
router closer to an exterior window or to another location within the facility can result in optimum reception.
Another way of increasing throughput is by physically placing the device on the roof of the building (in an
environmentally safe enclosure with proper moisture and lightning protection).
•
Simply install the GWR-HS Router outside the building and run an RJ–45 Ethernet cable to your
switch located in the building.
•
Keep antenna cable away from interferers (AC wiring).
Antenna Options
Once optimum placement is achieved, if signal strength is still not desirable, you can experiment with
different antenna options. Assuming you have tried a standard antenna, next consider:
•
Check your antenna connection to ensure it is properly attached.
•
High gain antenna, which has higher dBm gain and longer antenna. Many cabled antennas
require a metal ground plane for maximum performance. The ground plane typically should have
a diameter roughly twice the length of the antenna.
NOTE: Another way of optimizing throughput is by sending non–encrypted data through the device.
Application layer encryption or VPN put a heavy toll on bandwidth utilization. For example, IPsec ESP
headers and trailers can add 20–30% or more overhead.
