“…Propagation Path Loss Models at 60 GHz Bands for Access/Backhaul Links and D2D Communications for users of 4G cellular systems that operate at frequencies below 6 GHz [1], [2]. The vast amount of unregulated spectrum allocation for 60 GHz devices in many countries (roughly 7 GHz [1]) has attracted the cellular industry to explore the possibility of some harmonizations of this spectrum for use in the 5G mobile networks.…”

“…The first outdoor urban cellular environment was a hilly terrain type with high-rise buildings and some vegetation as shown in Fig. 3, while the second environment represents a hilly terrain type with high-rise buildings and rare vegetation [2]. In the first environment, we considered two 60 GHz deployment scenarios, access and backhaul links, while in the second environment, we considered two other scenarios, access and D2D links.…”

“…This signal was mixed up inside the upconverter with a local oscillator (LO) signal that was generated from an analog signal generator at a frequency of 5.4 GHz (i.e., f LO = 5.4 GHz). The output of the mixer is a radio frequency (RF) signal at 60 GHz mmWave band (i.e., f c = 60 GHz) [2]. The RF signal at the output of the mixer was then fed onto a highly directional horn antenna [with 7.3°half-power beamwidth (HPBW)], and finally transmitted over the wireless channel.…”

“…Recently, Sulyman et al [2] presented the initial results documenting the effects of solar radio emissions on path loss exponent (PLE) values at 60 GHz band based on outdoor measurements conducted in an urban environment. Solar radio noise is a phenomenon well known in the satellite community [18], [19], [26], [30], [32], [33].…”

This paper presents analytical and empirical data documenting the effects of solar radio emissions on outdoor propagation path loss at 60 GHz bands. Both line-of-sight (LOS) and non-LOS scenarios were considered. The setup used in the empirical studies emulates the future fifth-generation cellular systems for both access and backhaul services, as well as for device-to-device communications. Based on the measurement data collected in sunny weather with intense solar activities, we developed large-scale propagation path loss models at 60 GHz, and observed the effects of solar radio emissions on the path loss data. It is shown that solar radio emission can decrease carrierto-noise ratio, and that this translates into a corresponding increase in the path loss exponent (PLE) values for the largescale propagation path loss channel models. Empirical data show that 9.0%-15.6% higher PLE values were observed in hot and sunny weather during the day (41°-42°C) compared with the counterpart measurements taken at night in cool and clear weather (20°-38°C). This translates into a corresponding decrease in 60 GHz radio coverage in hot and sunny weather during the day. The empirical data are closely corroborated by analytical estimates presented. Index Terms-Fifth-generation (5G) cellular communications, path loss models, propagation measurements at 60 GHz, solar radio noise. I. INTRODUCTION M ILLIMETER wave (mmWave) spectrum, 30-300 GHz, will play a key role in the fifth-generation (5G) cellular networks, which aim to provide multigigabit per second (Gb/s) data rates over wireless links. Experts have been exploring the prospects of the 28, 38, 60, and 73 GHz mmWave bands for 5G systems. The unlicensed spectrum at 60 GHz offers 10-100 times more spectrum than what is available today Manuscript
