Using 76 signal strength receiver sites, Ordinary Least Square regression models predicted signal strength with 60% of variability explained in the Valley and Ridge province model and 43% of variability explained in the Blue Ridge province model.Region-specific statistical models were more accurate in determining a region’s transmitter placement and level of power for broadcasting compared to generic computer models.

Vainikainen, “Long range wideband channel measurements at 81−86 GHz frequency range,” In Proc. Antennas and Propagation (Eu-CAP’10), Barcelona, Spain, Apr.
Millimeter-wave frequencies offer large bandwidths for short-range indoor communications and outdoor point-to-point radio links.
In the first part of the thesis, different solutions for realizing integrated antennas in the 60-GHz frequency range are presented.
In this work, several antenna designs utilizing micromachining techniques have been developed and evaluated.
Avainkysymys, johon tarvitaan vastaus ennen kuin millimetriaaltolaitteita voidaan valmistaa kannattavasti suuria määriä on, miten edullinen ja suorituskykyinen antenni toteutetaan niin, että se voidaan integroida muiden lähetin- ja vastaanotinkomponenttien kanssa. Vainikainen, “60 GHz membrane antenna array for beam steering applications,” In Proc. Antennas and Propagation (Eu-CAP’12), Prague, Czech Republic, Mar.
Työn ensimmäisessä osassa esitellään erilaisia ratkaisuja integroitujen antennien toteuttamiseksi 60 GHz:n taajuusalueelle. In addition, beam steering has been demonstrated with the developed antenna arrays. The goal of the propagation part is to measure and model propagation channels in hospital environments, where 60-GHz radio systems can be used to improve the efficiency of medical operations and in urban outdoor environments, where millimeter-wave point-to-point links can be used for last mile access and backhaul of mobile networks. Vainikainen, “Measurement based path loss and delay spread modeling in hospital environments at 60 GHz,” IEEE Transactions on Wireless Communications, vol. Työssä on kehitetty kanavamalleja, jotka kuvaavat etenemiskanavaa viivealueessa, jotta esimerkiksi systeemisimulointeihin saadaan luoduksi riittävän suuri määrä kanavavasteita. Vainikainen, “5×1 linear antenna array for 60 GHz beam steering applications,” In Proc. Antennas and Propagation (Eu CAP’11), Rome, Italy, Apr. Väitöskirjan viimeisessä osassa analysoidaan millimetriaaltoradiojärjestelmien suoritus-kykyä sisätilaympäristöissä kanavakapasiteetin sekä fysikaalisen kerroksen tiedonsiirto-nopeuden avulla. Statistical analysis determined the significance between different terrain factors and signal strength.Field signal strength was found to be related to test site elevation, transmitter azimuth, elevation angle, transmitter elevation, path loss, and distance.Application of RFID sensors allows for a cheap, wireless, powerless system that could be deployed across large area.Current progress in this study has demonstrated a noticeable correlation between the received signal strength and the moisture content of the soil using radio frequencies of 902-928 MHz.The throughput starts to decline when the distance between the transmitter and the receiver exceeds 3 meters. Millimetriaaltotaajuuksien käyttöä pidetään vahvana ehdokkaana tulevaisuuden hyvin suuriin datanopeuksiin yltävien radiojärjestelmien toteuttamiseksi.
