It's often called mmWave . Global growth from mmWave . 四款“iPhone12”机型中只有两款可能支持mmWave 5G. Only two of four iPhone 12 models may support mmWave 5G. AT&T正在开发两种5G网络:mmWave 与sub-6GH。 Note that AT&T is working on two 5G networks- sub-6GHz and mmWave .
什么是5G和mmWave 你什么时候能够真实地使用它们? What are 5G and mmWave , and when will you be able to realistically use them? Many 5G systems will operate in millimeter wave(mmWave ) spectrum. 它可能不能提供mmWave 的高速,但它确实提供了覆盖。 It might not provide the high-speed of mmWave , but it does offer coverage. MmWave 是真正的5G体验-也就是说,直到我们获得更多的中频带。MmWave is the true 5G experience- that is, until we get more mid-band. 他们可以访问的唯一美国5G网络是mmWave 和Sprint的41频段。 The only US 5G networks they can access are mmWave and Sprint's band 41. Verizon:主要是mmWave ,使用其28GHz频谱并将其限制在城市区域。 Verizon: Primarily mmWave , using its 28GHz spectrum and limiting it to urban areas. 以这种方式使用,5GFWA相对于mmWave 的适用性因国家而异。 Used in this way, the applicability of 5G FWA over mmWave varies considerably by country. 毫米波(mmWave )是一类使用短波长电磁波的特殊雷达技术。 Millimeter-wave(mmWave ) is a special class of radar technology that uses short-wavelength electromagnetic waves. MmWave 5G设备与现有的4GLTE、蓝牙和WiFi产品的安全标准相同。MmWave 5G devices are bound by the same safety standards as existing 4G LTE, Bluetooth, and WiFi products. 如今,您可以看到mmW或mmWave,以及MMW和MMWAVE (针对使用大写锁定键的粉丝)等。 Today, you will see mmW or mmWave, and MMW and MMWAVE (for fans of the Caps Lock key), among others. MmWave (毫米波)--更高的频谱(频谱是一种有限资源),当前技术主攻方向;.MmWave (millimeter wave): higher spectrum(spectrum is a limited resource), the main direction of current technology; 通过利用TI的mmWave SDK平台,工程师可以在不到30分钟内开始他们的应用设计工作。 By leveraging the mmWave SDK platform, engineers can start developing their applications in less than 30 minutes. 例如,AT&T和T-Mobile都计划今年在全国范围内覆盖低频段频谱和mmWave 。 AT&T and T-Mobile, for instance, both plan to have nationwide coverage this year with both low-band spectrum and mmWave . AT&T和Verizon使用的是mmWave ,因为他们没有像样的宽带,大约75%的国家都是这种宽带。 AT&T and Verizon will use mmWave where they don't have decent broadband, about 75% of the country in each case. 这家韩国巨擘将在2019年下半年为AT&T提供第二支5G手机,以支持其mmWave 和sub-6-GHz网络。 The South Korean giant will supply a second 5G handset in the second half of 2019 to AT&T, supporting its mmWave and sub-6-GHz nets. 由于其物理限制,mmWave 的部署可能会局限在人口密集的地区,比如城市和体育场。 Because of physical limitations, they will likely limit mmWave deployments to densely populated areas such as cities and sports stadiums. 实际上,我见过最大600Mbps(理论最大值),那么使用400MHz频段,在mmWave 5GNR上应该能达到2.4Gbps。 In real life, I saw a maximum of 600Mbps when in theory, using 400MHz of spectrum should enable up to 2.4Gbps on mmWave 5G NR. 波束形成-用于mmWave 和低于6GHz的基站,将波形导向消费设备,例如从建筑物反射波。 Beamforming- used in mmWave and sub-6GHz base stations to direct waveforms towards consumer devices, such as bouncing waves off buildings. 根据专家机构和我们迄今为止的研究,没有任何迹象表明5GmmWave 是一个重大的健康风险,但很明显,有关该主题的研究还有待进一步研究。 According to expert agencies and the studies we have so far, there's nothing to suggest 5G mmWave is a significant health risk. MmWave 仅在中心城市的户外可用,但如果您在这些中心城市之一附近,则是70Mbps和700Mbps之间的差异。MmWave is only available outdoors in central cities, but if you're near one of those central cities, it's the difference between 70Mbps and 700Mbps. 根据专家机构和我们迄今为止的研究,没有任何迹象表明5GmmWave 是一个重大的健康风险,但很明显,有关该主题的研究还有待进一步研究。 According to expert agencies and the studies we have so far, there is nothing to suggest that 5G mmWave poses a significant health risk. 高通的创新允许终端设备制造商提供有吸引力的形式因素,结合极高的速度从mmWave 5GNR的好处。 The Qualcomm innovation allows terminal device producers to offer attractive form factors combined with the benefits of extremely high speeds from mmWave 5G NR. 并且5100下载速度高达2Gbps,低于6GHz,6Gbps,mmWave ,速度分别是前一代产品的1.7倍和5倍。 And the 5100 download speed is up to 2Gbps, lower than 6GHz, 6Gbps, mmWave , and the speed is 1.7 times and 5 times that of the previous generation. 为了减小容量混合处理信号带来的高成本开销和功耗,mmWave precoding将被分为模拟域和数字域。 Due to the high cost and power consumption of gigasample mixed-signal devices, mmWave precoding will likely be divided among the analog and digital domains. SuperDataLayer”由被称为mmWave 的高频频谱组成,适用于需要极高数据速率或人口覆盖率的区域。 There's the“Super Data Layer” made up of high-frequency spectrum known as mmWave that suits areas requiring extremely high data rates or population coverage.
