The basic concept of wired and wireless technology is the connection of wireless and wired endpoints, both of which require hardware and network connectivity. The organization or home network can choose a fully wired or wireless network. With a wireless network, users can be more mobile, but they are not as fast as wired. Therefore, many companies choose wired and wireless network configurations. See Figure 3 for architecture details.
Wireless Power Transmission, Wireless Power Transmission, Wireless Energy Transmission All electromagnetic transmissions are power transmission, and wires are not required as physical links. Wireless power transmission / technology uses time-varying electromagnetic field or electromagnetic field. Wireless power transfer technology can be divided into two types of known near field radiation and radiation or nonradiation techniques using short range power transmission via a magnetic field. Capacitive coupling between the electric coils or the inductively coupled metal electrodes between the electric fields Inductive coupling is the most widely used wireless technology such as charging handheld devices such as telephones and electric toothbrushes and implantable medical devices such as artificial hearts.

Zigbee is the latest wireless network technology based on wireless mesh network. It is used for short distance communication. Wireless mesh networks are known for their high repeatability and wide area coverage, and are commonly used in Zigbee Technolgy. It is very popular because of low setup cost and low power consumption. Because Zigbee is already in use in the elastic zone, the security of this layer is done by AES encryption. The message integrity code of the MAC layer is calculated using the payload and the header (possibly 4, 8 or 16 bytes long). Each frame has a frame number that is used to understand the order of the frames. This helps you to know when frames are lost, even when frames are played in case of foul play. The key to establishing and selecting the security to be used is done by upper layers.
