无连接的电话广播包
原标题:Broadcasting packets to a phone without a connection

这是一个很奇怪的问题, 但我知道这是可能的。

我试图用特定频率广播信息包,我想用一个运行应用程序的电话来接收这些信息包。 电话不需要连接任何网络就可以这样做,而只需打开wifi即可。 广播设备不需要从电话中获取任何信息,把每个信息包发送到电话也不必得到保证,这跟UDP一样。

我从哪开始呢?对于手机来说,这有可能不扎根吗?是否有某种FCC条例禁止这样做(针对标准的wifi频谱 )?

我知道这是可能的, 因为它正是路由者如何告诉一个可以连接的电话。 提前感谢任何输入 。
