xbee天线的通信范围如何确定

数据表中规格的XBee Pro最大范围将基于最佳条件下的视线。
确定您的期望将在很大程度上取决于您的条件。
“注意范围数字估计是基于干扰源有限的自由空气地形。
实际范围将根据发射功率，发射器和接收器的方向，发射天线的高度，接收天线的高度，天气条件，区域内的干扰源以及接收器和发射器之间的地形（包括室内和室外结构，如墙壁），
树木，建筑物，丘陵和山脉。“链接如下。
FCC批准的Atennas开始于第129页.Yagi天线从第131页开始，用于TH模块的SMT版本133

        XBee Pro max range as spec’ed in the datasheet would be based on line of sight in best conditions. To determine what you may expect would greatly depend on your conditions.

“Note Range figure estimates are based on free-air terrain with limited sources of interference. Actual range will vary based on transmitting power, orientation of transmitter and receiver, height of transmitting antenna, height of receiving antenna, weather conditions, interference sources in the area, and terrain between receiver and transmitter, including indoor and outdoor structures such as walls, trees, buildings, hills, and mountains.” Page 12 on link below.

FCC approved Atennas begining page 129. Yagi antennas begin on page 131 for SMT versions 133 for TH modules

谢谢你的答复。
我知道我可以在这些天线之间进行通信。
请你知道吗？没有任何天线，这就是为什么我不能用它们进行测试/你可以帮助我吗？我介绍这些天线链接。

        Thanks for reply. I would know that will i can communicate between these antennas. Please do you know that?İ dont have any antennas, thats why i cant test with them/ Could you help me about it?I introduce these antennas links.

你好@Suleymantural，
我确实和我的一位工程师谈过，他说你选择的部件组有几个问题。
您在Aliexpress上链接的Yagi看起来像标准Yagi，增益为25dBi。
我不知道你在哪里部署系统但是它会违反FCC，除非你在连接到天线的电缆中增加损耗，然后你必须进行测试以验证是否符合FCC。
除了主要问题之外，我看到的问题是，如果你想要Xbee的线天线版本和连接到Yagi天线的Xbee之间的链接，你将不会看到长距离，因为距离受到线天线的限制。
我可以问你想要获得什么样的范围以及你有什么干扰问题？
结构，天气等？
查看这些参数可能有助于提出可以与Xbee一起使用的建议。

        Hello @Suleymantural,
I did speak with one of my engineers and he stated there are a couple issues with the set of parts you selected.
The Yagi you have linked to on Aliexpress looks like a standard Yagi with 25dBi gain. I don’t know where you are deploying the system but it will be in violation of FCC unless you add loss in the cable going to the antenna and then you would have to test to verify meets FCC.
That issue aside the primary issue I see is if you want a link between a wire antenna version of Xbee and an Xbee connected to a Yagi antenna you are not going to see long range since range is limited by the wire antenna.
Can I ask what kind of range you are looking to get and what interference concerns you have? Structures, weather etc? Looking at these parameters may help in making a suggestion of something you can use with your Xbee.
