Abstract

This thesis considers the problem of low radio frequency (RF) signal strength at remote locations where connectivity has been proven to be problematic. In such areas, the low signal strength makes it more difficult for the residents to establish reliable internet connections. Moreover, in addition to long distance between mobile user and the base station the signal is degraded due to natural obstacles such as hills or forests. The most straightforward solution to the signal deterioration in this case is both elevating user’s antenna and amplifying the received signal by means of dedicated devices. In this regard, we have proposed two configurations for improving the signal strength. The former one, described as fixed installation is installed at home. The elevated modem with the antenna together with the integrated router were used in order to facilitate proper reception for home-dwellers. The latter one, is referred to as semi-mobile installation, where the directional antenna is mounted on the vehicle in order to enable connectivity for users on the go. The measurement campaign was conducted at remote locations in Loppula and Rokua, Finland. The targeted long term evolution (LTE) signal was measured at band 20 at 800 MHz. In case of semi-mobile installation the performance of the inductive coupler was measured in terms of signal parameters received signal strength indicator (RSSI), reference signal received power (RSRP), reference signal received quality (RSRQ) and signal-to-noise ratio (SNR). For the fixed installation, the modem performance was measured in terms of data rate. In both cases, the installed set-up improved the quality of the signal, and thus can be recommended for users facing connectivity issues at remote locations.
