A. How to Achieve Maximum Signal Strength with GWR-HS Router?
The best throughput comes from placing the device in an area with the greatest Received Signal Strength
Indicator (RSSI). RSSI is a measurement of the Radio Frequency (RF) signal strength between the base station and
the mobile device, expressed in dBm. The better the signal strength, the less data retransmission and, therefore,
better throughput.
RSSI information is available from several sources:
•
The LEDs on the device give a general indication.
•
Via the GWR-HS Router local user interface.
