![]() ![]() In this case, the closer we get to zero the better signal, unfortunately, that concept doesn’t apply to college exams. RSSI (Received Signal Strength Indicator) is the measurement we rely on to determine the strength of a signal of the client to the access point (Opengear Cellular device to Cellular tower). ![]() Today we’ll be covering cellular reception which is absolutely critical to maintaining a good connection to providing OOB access during network outages. % plotGrid(GRIDSIZE,CSIRSIND) plots the carrier grid of size GRIDSIZE % by populating the grid with CSI-RS symbols of multiple resources % indicated by a cell array of CSI-RS indices CSIRSIND.The two most common questions that arise when we begin discussing cellular out-of-band is reception and security. The purposes of these measurements include: For this measurement, CSI-RS transmitted on antenna port 3000 is used.ĬSI-RSRQ (CSI reference signal received quality): CSI-RSRQ is defined as, N * CSI _ RSRP CSI _ RSSI. CSI-RSSI includes the power from sources, such as co-channel serving and non-serving cells, adjacent channel interference, and thermal noise. This measurement is also performed across N number of resource blocks (measurement bandwidth). For this measurement, CSI-RS transmitted on antenna port(s) 3000 or 30 is used.ĬSI-RSSI (CSI received signal strength indicator): CSI-RSSI is defined as the linear average of the total received power observed only in the OFDM symbols, in which CSI-RS is present. This measurement is performed across N number of resource blocks (measurement bandwidth). CSI-RSRP (CSI reference signal received power): CSI-RSRP is defined as the linear average over the power contributions of the resource elements of the antenna ports, which carry CSI-RS configured for RSRP measurements. ![]()
