Unmanned Aerial Vehicles (UAVs) have been widely
used in military and civilian fields in the recent years. In order
to give support to the vast amount of added value services,
UAV communications have become a hot spot for the fifth
generation (5G) and have a very broad development prospect. In
this paper, based on the channel modeling results obtained by
actual measurements, we evaluate the end-to-end delay of Long
Term Evolution (LTE) for air-to-ground (A2G) communications
in suburban environments. The results show that, in order to
satisfy the reliability and latency requirements of the critical communications,
the base stations (BSs) deployment and the flight
routes need to be carefully considered since small increments on
the flight distance can have great influence on the packet success
rate and the end-to-end delay. The obtained results are of great
importance to evaluate if current LTE deployments can support
critical communications for cellular-connected UAVs.
