The table below shows recommended RSRP (Reference Signal Received Power) and RSRQ (Reference Signal Received Quality) values for LTE signals. See more on 4G Bands and 5G Bands in use in the U.S. On the other hand, mmWave bands can exhibit lower interference because of the narrow wavelengths (narrow pencil-like beams in the order of several millimeters) and shorter range which reduces opportunities for encountering interfering signals. However, such lower bands can exhibit higher interference because of the wider coverage and longer wavelengths. For example, a low frequency band such as LTE/NR band 71 can help operators achieve wider coverage (because of lower pathloss exhibited by lower frequency signals). Additionally, different LTE/NR bands could exhibit different levels of interference. Interference is often worse at the cell-edge. There are different types of interference sources (and different naming) including: self-interference, multiple-access interference, inter-cell interference, intra-cell interference, co-channel interference (CCI), adjacent channel interference (ACI), etc. Signal quality is primarily affected by interference. Gps-info <- LTE Modem GPS information.While most users of cellular devices understand that “signal strength” is important for good cellular signal reception, most folks do not realize that “signal quality” is by far a more determinant of the performance of 4G LTE and 5G NR cellular devices. Signal-info <- LTE Modem signal information.ĭata-session-info <- LTE Modem data session information. Sim-info <- LTE Modem SIM card information. Modem-details <- LTE Modem detailed information.
Traffic-status <- LTE Modem traffic status.
This article describes how to check the strength and other statistics of the SIM card (LTE/3g).įew commands to check the lte-modem stats: In cases where the Internet cannot be accessed, consulting the carrier about APN and set the APN in LTE modem configuration is possible using the below command: Most LTE modems have a preset APN in the SIM card.Īs a result, the APN doesn't need to be set in FortiOS configuration.
