Directional Measurements in Urban Street Canyons from Macro Rooftop Sites at 28 GHz for 90% Outdoor Coverage
Jinfeng Du, Dmitry Chizhik, Reinaldo A. Valenzuela +6
Path gain and effective directional gain in azimuth in urban canyons from actual rooftop base station sites are characterized based on a massive data set of 3000 links on 12 street…
Backscatter Measurements and Models for RF Sensing Applications in Cluttered Environments
Dmitry Chizhik, Jinfeng Du, Jakub Sapis +6
A statistical backscatter channel model for indoor clutter is developed for indoor RF sensing applications based on measurements. A narrowband 28 GHz sounder used a quazi-monostati…
Path Loss and Directional Gain Measurements at 28 GHz for non-Line-of-Sight Coverage of Indoors with Corridors
Dmitry Chizhik, Jinfeng Du, Rodolfo Feick +3
Adequate coverage with high gain antennas is key to realizing the full promise of the bandwidth available at mm/cm wave bands. We report extensive indoor measurements at 28 GHz (10…
Statistical Model of Time-varying Backscatter Power of Monostatic RF Sensing Channels in Urban Canyons
Dmitry Chizhik, Jakub Sapis, John Drogo +7
We present a measurement-based statistical model for the backscatter power ratio of monostatic RF sensing in urban canyons with moving clutter, suitable for large-scale system leve…
Channel and Spectrum Consumption Models for Urban Outdoor-to-Outdoor 28 GHz Wireless
Manav Kohli, Carlos E. Caicedo, Tingjun Chen +9
Millimeter-wave (mmWave) communication has been widely accepted as an enabler of 6G and other next-generation wireless networks, though high path loss strains link budgets, and dif…
Measured and Modeled Outdoor Indoor Coverage at 28 GHz into High Thermal Efficiency Buildings
Dmitry Chizhik, Jinfeng Du, Reinaldo Valenzuela +3
28 GHz outdoor-indoor coverage into modern office buildings with high thermal efficiency windows is found to be severely limited due to 46 dB median penetration loss at normal inci…
Suburban Fixed Wireless Access Channel Measurements and Models at 28 GHz for 90% Outdoor Coverage
Jinfeng Du, Dmitry Chizhik, Rodolfo Feick +3
Achieving adequate coverage with high gain antennas is key to realizing the full promise of the wide bandwidth available at cm/mm bands. We report extensive outdoor measurements at…
Suburban Residential Building Penetration Loss at 28 GHz for Fixed Wireless Access
Jinfeng Du, Dmitry Chizhik, Rodolfo Feick +3
Fixed wireless access at mm/cm bands has been proposed for high-speed broadband access to suburban residential customers and building penetration loss is a key parameter. We report…
Outdoor-to-Indoor 28 GHz Wireless Measurements in Manhattan: Path Loss, Environmental Effects, and 90% Coverage
Manav Kohli, Abhishek Adhikari, Gulnur Avci +12
Outdoor-to-indoor (OtI) signal propagation further challenges the already tight link budgets at millimeter-wave (mmWave). To gain insight into OtI mmWave scenarios at 28 GHz, we co…
