When additional range and link robustness are required, an RF front-end module (FEM)/range extender can be used to increase the range distance and the strength of the link's connection.
In addition to increasing range, an RF FEM also increases the robustness of the link connection. A more robust link leads to less packet loss, meaning less retransmissions. Retransmissions are redundant packets that reduce energy efficiency and maximum throughput. The probability of successfully receiving the first packet also increases, resulting in a more stable link latency.
Many applications can benefit from adding an RF FEM, including asset tracking, smart home, industrial, smart agriculture, audio, as well as professional lighting. Smart home, as well as industrial applications, benefit from extended range (e.g. range in an entire home). Audio applications benefit via increased throughput and decreased latency.
