Radio Channel Characterization of Mid-Band 5G Service Delivery for Ultra-Low Altitude Aerial Base Stations

Abstract: This paper presents a study which evaluated the potential for using ultra-low altitude, unmanned aerial vehicles to deliver fifth-generation (5G) cellular connectivity, particularly into areas requiring short-term enhancement in coverage. Such short-term enhancement requirements may include large gatherings of people or during disaster scenarios where there may be service outages or a need for increased bandwidth. An evaluation of this approach was conducted with empirically generated results regarding signal … Show more

“…where d is distance in meter, α represents the path loss exponent and β is the intercept point with the line d = 1 m, and X σ is a random variable that accounts for shadowing variation modeled with normal distribution and standard deviation σ . Using ultra-low altitude (5 m -15 m) UAVs to deliver 5G cellular mobile services, Catherwood et al [69] investigated the channel gain, mean time delay and the RMS spread of the delay at three different drone heights for an open area, a tree-lined environment, and an enclosed area at 3.4 GHz -3.8 GHz. They find that it is Rician distributed for the received signal strength, whereas mean time delay and RMS-DS for the open and tree-lined environments are Weibull distributed with the enclosed area tests being lognormally distributed.…”

“…Band 42 and Band 43 range from 3.4 to 3.6 GHz and 3.6 to 3.8 GHz, respectively [16]. Moreover, 3.4-3.8 GHz is also the range for mid-band 5G communications for the EU licensed band [17]. The shared 5-GHz LTE-U band ranges from 5.150 to 5.925 GHz [2].…”

“…However, the RPC modelling needs to be further investigated for the partially and fully obstructed channel because channel models in LOS distinctly differ from that of non-LOS (NLOS) [62]. An A2G channel modelling in the open area by investigating both large and small scale parameters within 3.4 -3.8 GHz frequencies was done in [63]. Another measurement campaign limited to open area and 40 m altitude in 1.2 GHz band for A2G channel modelling was done in [64].…”
