RF模塊（射頻模塊）是（通常）小型電子設(shè)備，用于在兩個(gè)設(shè)備之間發(fā)送和/或接收無線電信號(hào)。在嵌入式系統(tǒng)中，通常需要與另一個(gè)設(shè)備進(jìn)行無線通信。該無線通信可以通過光通信或通過射頻RF模塊通信來實(shí)現(xiàn)。對(duì)于許多應(yīng)用，選擇介質(zhì)是RF，因?yàn)樗恍枰暰€。射頻通信包含一個(gè)發(fā)射器和一個(gè)接收器。
射頻模塊的特點(diǎn)：
1.成本低
無線數(shù)據(jù)傳輸模塊建立了專用的無線數(shù)據(jù)傳輸模式，既節(jié)省了人力和物力，又節(jié)省了投資。
2.工期短
要使用數(shù)據(jù)傳輸模塊建立專用的無線數(shù)據(jù)傳輸方法，只需安裝適當(dāng)高度的天線，工程周期只需幾天或幾周。相比之下，無線方法可以快速建立通信鏈接，并且工程周期大大縮短。
3.適應(yīng)性強(qiáng)
使用無線數(shù)據(jù)傳輸模塊來建立專用的無線數(shù)據(jù)傳輸方法將比有線通信具有更好，更廣泛的適應(yīng)性，并且?guī)缀醪皇艿乩憝h(huán)境的限制。
4.良好的可擴(kuò)展性
如果使用無線數(shù)據(jù)傳輸站來建立專用的無線數(shù)據(jù)傳輸方法，則僅通過將新設(shè)備與無線數(shù)據(jù)傳輸站連接就可以實(shí)現(xiàn)系統(tǒng)的擴(kuò)展，相比之下具有更好的可擴(kuò)展性。
5.設(shè)備維護(hù)
有線通信鏈路的維護(hù)需要沿線進(jìn)行檢查。當(dāng)發(fā)生故障時(shí)，通常很難找到故障的時(shí)間點(diǎn)。然而，使用無線數(shù)據(jù)傳輸模塊來建立專用的無線數(shù)據(jù)傳輸方法僅需要維護(hù)數(shù)據(jù)傳輸模塊，并且可以在發(fā)生故障時(shí)迅速找到它。如果找到原因，則設(shè)備可以及時(shí)恢復(fù)正常。

RF module (RF module) is a (usually) small electronic device used to send and / or receive radio signals between two devices. In embedded systems, wireless communication with another device is usually required. The wireless communication can be realized by optical communication or by RF module communication. For many applications, the medium of choice is RF because it does not require a line of sight. RF communication consists of a transmitter and a receiver.

Features of RF module:

1. Low cost

The wireless transmission mode saves both manpower and material resources.

2. Short construction period

To use the data transmission module to establish a special wireless data transmission method, it only needs to install an antenna of appropriate height, and the engineering cycle only needs a few days or weeks. In contrast, the wireless method can quickly establish communication links, and the engineering cycle is greatly shortened.

3. Strong adaptability

Using wireless data transmission module to establish a special wireless data transmission method will have better and wider adaptability than wired communication, and is almost not limited by geographical environment.

4. Good scalability

If the wireless data transmission station is used to establish a special wireless data transmission method, the expansion of the system can be realized only by connecting the new equipment with the wireless data transmission station, which has better scalability.

5. Equipment maintenance

The maintenance of wired communication link requires inspection along the line. When a fault occurs, it is usually difficult to find the time point of the fault. However, using the wireless data transmission module to establish a dedicated wireless data transmission method only needs to maintain the data transmission module, and it can be found quickly in case of failure. If the cause is found, the equipment can return to normal in time.
