使用高增益天线实现足够的覆盖是实现厘米/毫米波段宽带宽的关键。我们报告了广泛的室外测量在28 GHz的郊区住宅区在新泽西和智利，超过2000个链接测量相同的街道链接类型[植被阻挡视线（LOS）]从13条街道和其他街道链接类型[真正的非LOS（NLOS）]从7条街道，使用一个专门的窄带通道探测器在范围达到200米。适用于固定无线接入的测量涉及放置在临街窗户外部的55发射天线和在货车桅杆顶部以3米高度旋转的10接收喇叭天线，模拟灯柱安装的基站（BS）。测得的路径增益-距离的依赖性是很好地表示幂律模型，和方位角增益在基地通过散射退化超过4.3 dB的10个链接。已经发现，在BS处具有51 dBm的有效各向同性辐射功率（EIRP）并且在室外安装的终端处具有11 dBi天线的情况下，可以从部署在相同街道中的BS以90度覆盖保证递送高达100 m的lGb/s下行链路速率。
Achieving adequate coverage with high gain antennas is key to realizing the full promise of the wide bandwidth available at centimeter/millimeter bands. We report extensive outdoor measurements at 28 GHz in suburban residential areas in New Jersey and Chile, with over 2000 links measured for the same-street link types [vegetation blocked line of sight (LOS)] from 13 streets and other-street link types [true non-LOS (NLOS)] from 7 streets, using a specialized narrowband channel sounder at ranges reaching 200 m. The measurements, applicable to fixed wireless access, involved a 55 transmit antenna placed on the exterior of a street-facing window and a 10 receive horn antenna spinning on top of a van mast at 3 m height, emulating a lamppost-mounted base station (BS). The measured path gain-distance dependence is well represented by power-law models, and azimuth gains at the base are degraded through scattering by more than 4.3 dB for 10 of links. It was found that, with 51 dBm effective isotropic radiated power (EIRP) at the BS and 11 dBi antenna at an outdoor- mounted terminal, 1 Gb/s downlink rate can be delivered up to 100 m from a BS deployed in the same street with 90 coverage guarantee.
