“…Recent years have seen great advances in mm-wave phased antenna arrays and corresponding transceivers for base stations (BSs) and user equipment (UE). For instance, Samsung [17] has presented a 28 GHz base station with a 64-element phased antenna array, IBM and Ericsson [15] have demonstrated a dual-polarized 28 GHz phased antenna array module with 128 elements, and Sivers IMA has released 16-element mm-wave phased antenna array [16]. However, these new mm-wave transceivers and phased antenna array designs have largely been evaluated in controlled environments [15]- [17], rather than in real outdoor urban settings.…”

Exploiting multi-antenna technologies for robust beamsteering to overcome the effects of blockage and beam misalignment is the key to providing seamless multi-Gbps connectivity in 5G-and-beyond mm-wave networks. In this paper, we present the first large-scale outdoor mm-wave measurement study using a phased antenna array in a typical European town. We systematically collect fine-grained 3D angle-of-arrival and angleof-departure data, totaling over 50,000 received signal strength measurements. We study the impact of phased antenna arrays in terms of number of link opportunities, achievable data rate and robustness under small-scale mobility, and compare this against reference horn antenna measurements. Our results show a limited number of 2-4 link opportunities per receiver location, indicating that the mm-wave multipath richness in a European town is surprisingly similar to that of dense urban metropolises. The results for the phased antenna array reveal that significant losses in estimated data rate occur for beam misalignments in the order of the half-power beamwidth, with significant and irregular variations for larger misalignments. By contrast, the loss for the horn antenna is monotonically increasing with the misalignment. Our results strongly suggest that the effect of non-ideal phased antenna arrays must be explicitly considered in the design of agile beamsteering algorithms.

“…In this paper, we have extended the work presented in [15] by adding more results and especially including the beam steering measurements. This beam steering is performed with 2 × 16 phased antenna array fed through a 16 × channel RFIC.…”
