如何将TX/RX功率修改为天线？

问答对人有帮助，内容完整，我也想知道答案 0 大家好，对于我的MSC论文，我尝试开发定向天线用于WiFi通信，以节省与IOT设备相比，机载/外部全向天线的一些功率。关于2个问题： 1）如何将TX/RX功率修改为天线？当然，如果可能的话。更具体地说，我对粒子光子感兴趣，我相信它们使用Cypress Wice。 2）我如何修改WiFi子系统来选择特定的天线（假设我有多个定向天线，比如4个向北、南、East、欧美地区）？我想如果我能把天线号放在什么地方就好了。我也不知道当前的WiFi标准是否有类似于“天线号”的数据包格式。请提出建议和想法… 万事如意凯末尔·基里克可持续环境与能源系统系中东技术大学北塞浦路斯分校 G·Zelyurt -塞浦路斯以上来自于百度翻译以下为原文 Hello Folks, For my MSc thesis, I am trying to develop directed antenna for wifi communication to save some power for IoT devices compared to onboard/external omni-directional antennas. For that 2 questions: 1-) How can I modify the tx/rx power to an antenna? If it is possible of course. More specifically I am interested in Particle-Photons, which they use Cypress WICED I believe. 2-) How can I modify the wifi subsystem to select specific antenna (assuming I have multiple directed antennas, like 4 of them towards North, South, East, West) ? I guess it will be nice if I can put the antenna number somewhere. I also do not know if current wifi standard has something like "antenna number" in the packet format. Please suggestions and ideas..... All the best Kemal Kilic Dept. of Sustainable Environment And Energy Systems Middle East Technical Univ. North Cyprus Campus Güzelyurt - Cyprus 0

答案对人有帮助，有参考价值 0 你好，凯末尔： 1）如何将TX/RX功率修改为天线？当然，如果可能的话。答：我们可以修改发射功率、接收灵敏度取决于模块的设计和天线设计。而且，我们有两个方法修改的权力，一个是在SDK发布的NVRAM修改电源。另一个是修改FW直接，我们建议客户使用第一个因为你需要频繁更新固件如果功率不匹配。二）我怎么修改WiFi系统选择特定的天线（假设我有多个定向天线，像他们往北，南，East，欧美地区）？ A：我知道我们现在使用的天线分集做天线开关，它是在我们的发布两天线。我们需要一个算法来选择最佳的天线产品时移动或旋转，如果你用四，使得选择呆很复杂。它需要的物理天线开关控制引脚上的天线。以上来自于百度翻译以下为原文 Hi Kemal: 1-) How can I modify the tx/rx power to an antenna? If it is possible of course. A: We can modify the TX power, RX sensitivity is depended on the module design and the antenna design. And, we used to have two ways to modify the power, one is to modify the power on the NVRAM released in the SDK. another is to modify the FW directly , we suggest customer to use the first one because you need to update FW frequently if power not matched. 2-) How can I modify the wifi subsystem to select specific antenna (assuming I have multiple directed antennas, like 4 of them towards North, South, East, West) ? A: As I know now we used to use antenna diversity to do the antenna switch , and normally it is two antennas in our release. we need a arithmetic to select the best antenna when the product is moving or rotating , if you used four, that makes the selection stay very complicated. and it need the physical antenna control pin to switch the antenna on .
