rohde & schwarz is advancing its pioneering sub-thz research in the d-band and has reached important milestones. in collaboration with the berkeley wireless research center (bwrc), the test and measurement expert has successfully characterized a tx/rx multi-antenna chip (charm) operating at up to 140 ghz, using their d-band over-the-air (ota) test chamber. academia and industry leaders agree that the 110 ghz to 170 ghz frequency range, known as d-band, is critical for beyond 5g and 6g mobile communications and future automotive radar applications.
lte user equipment (ue) receiver performance has significant impact to cellular radio network coverage and capacity. it determines the maximum data throughput across the air interface between the lte base station (enb, evolved node b) and the mobile network subscriber ue, thus it determines the total capacity across the air interface. therefore, it is one of the most important measurements to verify the actual receiver performance of individual devices, and a key metric to compare different devices, in particular.this paper shall give an introduction to receiver performance measurements and discusses the measurement metrics as well as the challenges of over the air (ota) measurements.

面向生产和研发的综合性测试九游官网下载的解决方案指南
小基站是一种紧凑型基站，和常规的宏基站相比体积更小、传输功率更低。小基站的覆盖范围相对较小，承载的用户量也更少。一般而言，小基站能够集成到现有的移动网络中。无线接入技术持续演进，小基站的作用也随之不断变化。在 2g/3g 时代，小基站被用于在极端情况下提供覆盖。在之后的 lte 时代，基站网络不仅提供覆盖，还提供容量。小基站被用于根据需要提供附加容量，不额外增加频谱。在当下的 5g 时代，网络运营商采用关键的密集化策略来提供流畅一致的 5g 服务，这同样需要保障网络覆盖、容量和性能。对于需要部署 5g 毫米波 (mmw) 的应用，考虑到毫米波的传播特性，可以通过小基站有效增加基站密度。在本应用指南中，我们将探讨产品生命周期中的小基站测试，并使用无线电综测仪 r&s®cmp200 和 ota 暗箱 r&s®cmq200 重点针对拆分选项 6 讨论空口 (ota) 环境中 fr2（频率范围 2，毫米波频段）的小基站被测设备 (dut) 的生产测试九游官网下载的解决方案。指南的第二部分将更加深入地介绍典型研发测试应用中使用的测试九游官网下载的解决方案。
