- Issue Time
Sertag base station adopts Hopping technology.
Although it works in a frequency band, Wi Fi devices usually work on a fixed channel and use the channel in a competitive way. Sertag electronic shelf labels solution for 2.4G adopts frequency hopping technology, which transfers from one channel to another at a frequency of 1600 hops per second according to the agreed random sequence. The device sends and receives data in one channel for a fixed time (625us), and then jumps to another channel. There is only a small probability that it will be affected by Wi Fi signals. Moreover, we have adopted the method of sending repeatedly to ensure the success rate of data.
