实际上没有关系。但是后来人们逐渐习惯用WIFI来称呼802.11b协议。它的最大优点就是传输速度较高,可以达到11Mbps,另外它的有效距离也很长,同时也与已有的各种802.11 DSSS设备兼容。笔记本电脑技术——迅驰技术就是基于该标准的。

您好,我已将旧的无线网卡更换为英特尔AC 7260(7260.HMWWB.R)数周。在互联网连接上没问题。但是,当使用蓝牙设备时,它通常会有中断,大约每30-60分钟一次。例如,我的耳机以低速重复声音(就像播放旧的划痕音乐一样)几秒钟。使用我的鼠标,它在移动时会中断几秒钟。有时它完全失去与设备的连接,尽管它仍然显示连接了2个设备。我已经与另一个蓝牙鼠标进行了双重检查,但问题仍然存在。但是,如果他们使用我的东西,我的朋友没有任何问题。我正在使用Sony Vaio FIt 14“笔记本电脑(SVF14A16SGS),Windows 10 Home 64位(Build 17134)。蓝牙驱动程序:20.60.0.4请告诉我该怎么办。提前致谢!以上来自于谷歌翻译以下为原文Hi there, I've change my old wireless card to Intel AC 7260 (7260.HMWWB.R) for few weeks. It's ok on Internet connection. However, when using bluetooth devices, it often has interrupts, about every 30 - 60mins. For example, my headphone has repeated voice in slow speed (just like playing an old scratched disc music) for few secs. With my mouse, it's interrupted for few secs while moving. Sometimes it's totally lost connections with devices although it still shows that 2 devices connected.I've made a double check with another bluetooth mice but the problem is still there. However, my friend doesn't have any problem if they using my stuff.I'm using Sony Vaio FIt 14" laptop (SVF14A16SGS), Windows 10 Home 64-bit (Build 17134).Bluetooth driver: 20.60.0.4Please let me know what should I do. Thanks in advance!

时间回到2009年,当我们还在考虑是否要升级到300M无线网络的时候,当IEEE(美国电气和电子工程师协会)还正在着手研发下一代千兆(1Gbps)网无线标准——802.11ac/802.11ad的时候,一个全新的无线吉比特联盟(Wireless Gigabit Alliance)悄然成立了,这一无线联盟仅用不到一年的时间就完成了新千兆无线网络标准的制定工作,并于2010年5月颁布了正式的WiGig(Wireless Gigabit,无线千兆比特)标准。 为什么全新的WiGig标准能制定的如此高效呢?如果你了解这个联盟的组成成员,你就不会对这样的速度感到惊奇了。下面就让我们一起来看看这个联盟的阵容究竟有多豪华。

大家好,我是使用EMpro的新手,我一直在使用Momentum来进行EM模拟。我试图从ADS布局导出到EMpro运行模拟,我得到一个脚本错误。我无法加载整个脚本(请参阅附件)导入时出现问题。因此,我不知道如何添加端口来模拟天线S参数。我不熟悉这个工具,似乎很难添加一个模拟端口。有人可以告诉我如何添加端口到这个测试天线,所以我看看它的S11参数。我有兴趣知道它的共振频率和电感,如果允许我输入方程式。另外,EMpro可以模拟由Air分隔的两个天线,并且参数化地仅从左到右,从上到下,向上和向下移动天线中的一个?一个天线将固定另一个天线相对于另一个创建一个音量。固定天线将以40V峰值电压或大约200mA激励,另一个将拾取场并将其转换为我可以测量的电流?这在EMPro中是否可行?在其他工具中,我只是想找出EMpro的功能。谢谢大家的帮助EMPro_Import.py30.6 KB 以上来自于谷歌翻译 以下为原文Hello everyone, I am very new to using EMpro, and I have been using Momentum to do EM sims.I am trying to run a simulation from ADS Layout export that to EMpro, and I got an scripting error.I could not load the entire script (see attached) there was an issue with the import. As a result, I don't know how to add ports to simulate the antenna S-parameters.I am not familiar with this tool, and it seems hard to just add a simulation port.Can someone please tell me how to add ports to this test antenna so I look at the S11 parameters for it.I am interested to know its resonant frequency, and inductance if allows me to enter equations. Additionally, can EMpro simulate two antennas separated by Air and parametrically move only one of the antenna left to right and top to bottom and up and down?One antenna would be fixed the other moves relative to the other creating a volume.The fixed antenna will be excited with 40V peak voltage or perhaps about 200mA, and the other would pick the field and converts it to a current I can measure? Is this possible in EMPro?It is possible in other tools, I am just trying to find out the capabilities of EMpro. Thank you all for your Help附件TEST_ANTENNA.ep.zip45.1 KBEMPro_Import.py30.6 KB
