Modem light status - Successful install and expected status of a good quality circuit

The success of Sierra Wireless and MCS is made possible due to excellent availability to reliable, effective service. Our customers expect a stable signal to the modem that is always connected with significant bandwidth performance.

This stability is shown on the front of the modem with the following light status:

Network - Solid Green

Signal - Solid Green

Power - Solid Green

Activity - Flashing Green (if connected) OR

No light - no data being transmitted (if no connection, check the ethernet cable)

This light status should provide the modem with the following signal metrics:

Signal Strength (RSSI) -25 to -75 - RSSI is a typical relative received signal strength in a wireless environment. RSSI is an indication of the power level being received by the receiving radio after the antenna and possible cable loss.
LTE Signal Strength (RSRP) -50 to -100 - The power of the LTE Reference Signals spread over the full bandwidth and narrowband.
LTE Signal Quality (RSRQ) no higher than -15 Indoors/Outdoors - Quality considering also RSSI and the number of used Resource Blocks (N) RSRQ = (N * RSRP) / RSSI measured over the same bandwidth.
LTE Signal Interference (SINR) 0 to 15 - The signal-to-noise ratio of the given signal.

Having a good and stable signal can significantly increase the lifelong success of the circuit and ensure more customer satisfaction for the future of our company and our business.
