Wideband Performance Comparison between the 40 GHz and 60 GHz Frequency Bands for Indoor Radio Channels

Abstract

When 5G networks are to be deployed, the usability of millimeter-wave frequency allocations seems to be left out of the debate. However, there is an open question regarding the advantages and disadvantages of the main candidates for this allocation: The use of the licensed spectrum near 40 GHz or the unlicensed band at 60 GHz. Both bands may be adequate for high performance radio communication systems, and this paper provides insight into such alternatives. A large measurement campaign supplied enough data to analyze and to evaluate the network performance for both frequency bands in different types of indoor environments: Both large rooms and narrow corridors, and both line of sight and obstructed line of sight conditions. As a result of such a campaign and after a deep analysis in terms of wideband parameters, the radio channel usability is analyzed with numerical data regarding its performance.

Effect of Space Diversity for Fading Mitigation at 40 and 60 GHz Indoor Channels

“…To have an idea of how the environment affects the radio waves, the PDP received from the antenna at the front (S 31 ) for the four case studies is ploted in Figure 5 . More information about that can be found in [4]. A couple of things can be pinpointed:…”

Millimeter-Wave Communications

“…Each of the twelve papers collected in this Special Issue contributes to a solution to one or more of the challenges described in the introduction. Regarding radio wave propagation, Rubio et al [1] provide an experimental characterization of the path loss and time-dispersion of an in office radio channel at 26 GHz, while in a study by Riobó and colleagues [2], wideband results at 40 GHz and 60 GHz frequency bands are also provided for indoor environments.…”

A Wideband Radio Channel Sounder for Non-Stationary Channels: Design, Implementation and Testing

“…Thereby, VNA-based sounders are typically used indoors and over short distances. As in the STDCC case, these sounders have been widely used [20][21][22][23]. 7.…”
