在过去的几年中，对无线通信的信任在整个行业中迅速传播。一旦保留主要是在难以通过电线到达的地方连接设备，或者将设备不友好地旋转到附加的接线时，无线网络现在即使在易于线的应用中也扩展，因为它具有可靠的可靠性，可靠性和易于设置和适应性。另外，通过几乎不断依赖智能手机，我们都对无线变得更加满意。
To ensure the levels of reliability required by industry, attention to detail in wireless communication installation is more involved than setting up a home or office wireless network. To address the key issues around wireless antenna selection and setup for industrial applications,Prosoft技术has released an educational video (which can be viewed at the bottom of this article) that explains many of the key facets of antenna technology that are quickly becoming a core requirement for industrial communications.
例如，该视频突出显示了Omni和定向天线的差异。为了详细说明天线的不同类型的信号发送和接收功能及其范围限制，视频提供了口头和图形描述。
The most common industrial types of wireless antennas are also discussed, including:
- 划线阵列天线（OMNI类型） - 本质上是几个线性天线，彼此堆叠以增加增益，以帮助从多个方向接收/发送信号；
- Width antennas (straight and articulating omni types) — widely used for mobile worker applications;
- Yagi（定向类型） - 由线性元件阵列组成，使信号从天线吊杆中辐射到光束中；
- Parabolic reflector (directional type) —a dish and feed antenna where power radiates from the feed antenna toward a reflector which concentrates the signal into a narrow beam; and
- Panel (directional type) — also known as a path antenna, these thin and rectangular antennas have a low profile and are weather resistant, but are not as focused as Yagi and parabolic types.
影响天线选择和放置的三个关键电特性（pattern，增益和极性）也引起了人们的关注。
MIMO (multiple input/multiple output) is addressed in the video, explaining how this method takes advantage of a natural radio wave phenomenon known as multipath—where signals bounce off walls, ceilings and other objects to reach the antenna from multiple angles, multiple times. Though this radio wave behavior was known to cause signal interference in the past, MIMO-enabled antennas can take advantage of this multi-path behavior to increase communication performance. In fact, all wireless products with 802.11n support MIMO, which is key to allowing those devices to deliver much higher communication speeds.
最后，视频地址关键天线安装问题，包括频率和极性考虑，安装位置问题，危险问题以及如何评估增益要求。
