With RSRP values for all the nearby towers, the modem chooses the tower with the best RSRP. A connection with a high RSRQ should be good, even if the RSRP is low: the modem is able to extract the information in the weak signal because of minimal noise. The LTE specification defines a second value, RSRQ (Reference Signal Received Quality), as the ratio of the carrier power to the interference power: essentially this is a signal-noise ratio measured using a standard signal. the closer to zero it is, the higher the power of the signal.
RSRP values, presented in dBm, are always negative, and the higher the number, ie. This is the measured power of the LTE reference signals spread across the broadband and narrowband portions of the spectrum. LTE technology includes reference signals which a modem uses to assess the state of the connection to a given cell tower in a standard way.Ī modem determines which tower to connect to on the basis of a value called RSRP (Reference Signal Received Power). Cellular modems - ‘User Equipment’ (UE) in the jargon - continuously monitor signals transmitted by all nearby cell towers so that they can always connect to the one with the best signal. Work with the Breakout SDK for Narrowbandįortunately, cellular communications technology was developed specifically to cater for these factors.
