Be aware of the location of the carrier's cellular tower and position accordingly.close to an exterior window or to a higher point in the building, on top of tall cabinets, etc. Select the optimum placement for the antenna, e.g.Keep the antenna and antenna cable away from AC wiring and other interference, such as other electrical or radio devices.Place the antenna outside any metal racks and cabinets, which may induce a Faraday cage effect.Ensure both MAIN and AUX antennas are properly connected.
Antenna selection and placement can drastically affect signal strength: Specialist equipment is available, however a standard cellular phone with a SIM from the same carrier will typically suffice.Ģ. It may be useful to undertake a signal strength site survey to profile your site prior to installation. The LED status is updated every 5 seconds. No LEDs lit: Unacceptable signal, check antenna connection If your Opengear device has signal strength LEDs, refer to the following: This displays the current state of the cellular modem, including RSSI labeled either signal-lte-rssi or rssi. Login to the Opengear CLI as root or an admin user and run: cellctl -l -s This displays the current state of the cellular modem, including RSSI labeled either LTE RSSI (dBm) or Received Signal Strength Indication ( RSSI in dBm). Login to the Opengear web UI as root or an admin user and click Status -> Statistics -> Cellular. There are three ways to check signal strength, via the Opengear web UI, the command line, and via the chassis LEDs.īefore measuring signal strength, configure your cellular connection to ensure the readings are measuring the appropriate carrier and band. 89 dbm to -70 dBm: Medium to high signal 100 dBm or less: Unacceptable signal, check antenna connection It is generally expressed in dBm and the best cellular throughput is achieved when the Opengear device and/or its antennas are positioned to maximize RSSI. RSSI (Received Signal Strength Indicator) is a measurement of the Radio Frequency (RF) power present in a received radio signal at the mobile device.
