The maximum power for LTE (RSRP) at the antenna connection of user equipment is − 25 dBm. 3 GHz on AT&T, 2. 9. the reference signal received power (RSRP) on a regular basis and connects to the cell that results in the best-received signal quality [16]. The statistical analysis shows that the existing LTE networks are able to provide a reliable communication link for UAVs at a distance up to 400 m and elevation angle up to 30 degrees, while the RSRP is in the range of −59 dBm to −79 dBm and RSRQ is in the range of −9 dB to −14 dB. 72" N and longitude 000° 14׳ 33. In fact, a mapping is applied to RSRP measurements prior to including them within RRC messages. Deployment density.
