Abstract
Starting from outdoor transmission, crossing vegetation, the wideband and narrowband characterization of the indoor mobile radio channel in the 700 MHz band is obtained from experiments carried out in the indoor environment of the Engineering building at Fluminense Federal University, and from the processed data, respectively, the power-delay profiles obtained permitted to calculate the time dispersion parameters and the envelope of the signal permitted to adjust probability density functions to the signal variability, concluding about the influence of vegetation on those characteristics.
Highlights
The access to mobile networks has been growing notoriously throughout the world
The main goal of this paper was to characterize the indoor channel for the 700 MHz frequency band with outdoor transmission and vegetation between the transmitter and the receiver
The carrier of 768 MHz was used for narrowband sounding whereas an OFDM signal composed of 2048 carriers and in the range of 768 10 MHz band was chosen for the wideband transmission
Summary
The access to mobile networks has been growing notoriously throughout the world. LTE was designed to support rates greater than 100 Mbps (downlink) and 50 Mbps (uplink) using a 2x2 MIMO scheme and 20 MHz bandwidth. This ensures optimal spectral efficiency and smaller connection latency time - less than 100 milliseconds. It has metrics such as resource requirements, priority in the routing queue, packet delay time, and packet loss rate to choose the best traffic route [1]
