Wireless communication networks
In addition to standardized protocols for the implementation of wireless transmission, there are a number of original (not approved as standard) protocols. The frequency range is 200 MHz to 3.9 GHz. Several blocks are used in the implementation. On the receiving side there is an antenna, which receives the signal. A bandpass filter clears the received signal of unnecessary frequencies. After cleaning, several downscalers on the receiving path convert the carrier frequency into an intermediate frequency (IF). Then signal processing blocks (baseband) are created, which are obtained from the in-phase/square (I/Q) stages. There are various ways of separating the system into separate stages. For example, when using ZigBee technology, the block is implemented with the help of crystal based systems. And in cases when developers use original protocols, the radio channel is built on a separate digital information system, made to order.
