In the fifth generation mobile communications system (5G), it is expected to use millimeter wave (mmW) radio access with very wide frequency bandwidths of more than 1 GHz.

This paper presents field experiments on the downlink performance of a 5G radio access system employing higher rank MIMO in the quad-directional antenna configuration at UE side comparing the uni-d

This paper presents field experiments on the downlink throughput performance of a 5G centimeter wave radio access system employing higher rank MIMO in a shopping mall environment and a long corrido

This paper presents field experiments on the downlink throughput and SNR performance of a beam forming 5G millimeter wave radio access system with beam tracking in the following urban environments:

This paper presents field experiments on the downlink throughput performance of a beam tracking proof-of-concept system targeting 5G millimeter wave radio access in the following typical small cell

High contact resistance has been observed with relays containing Au10Ag (10 weight percent Ag) contacts after approximately one year in the field.

In this report, the optical field fluctuations produced by four-wave mixing processes in fibers are studied in detail.

We have measured the isotope shifts between sup 36,38,40 Ar I using Doppler-free intermodulated optogalvanic spectroscopy on the 4p-5d transition at 604.3 nm.

The isotope shifts between sup 36, 38, 40 Ar on the 4p-5d transition at 604.3nm in Ar I have been measured using the Doppler-free intermodulated optogalvanic spectroscopy technique.

IEEE This paper has two main objectives. First, it describes the practical challenges of field trials and proposes a developed test method.
