introduction If you can wirelessly control all devices in the same place, you can simplify your day's work. When you arrive at the warehouse in the morning, you can use remote control equipment, turn on the temperature sensors in the lights, air conditioning units (HVAC) , and refrigeration equipment, then turn off the security system, and send the shelves or equipment list to the workers who manufacture the products. During work hours, you can check whether the garage in your home is locked, whether the lights are turned off, whether the temperature setting of the temperature adjustment device is too high, whether the oven is turned off, whether the safety system is turned on, and whether the shutters are open. At home in the evening, you can use the wireless keyboard and mouse to check e-mail, help your child turn on wireless learning toys, and communicate with your entertainment center through remote control equipment. All of the above functions can be achieved through smart home and office applications with flexibility and seamless mobility without the need for line connections. Introduction to 802.15.4 Technology Freescale Semiconductor ( formerly Motorola Semiconductor Division of Freescale Semiconductor ) is an important member of the IEEE 802.15.4 standards body. The 802.15.4 specification is a cost-effective, low data rate (<250 kbps) , 2.4 GHz, and 868/928 MHz wireless technology used in personal area networks and peer-to-peer mesh networks. Target markets for the 802.15.4 standard include: industrial control and networking, home automation and control, inventory management, human-machine interface devices, and wireless sensor networks. The 802.15.4 standard is the basis for ZigBee applications and network layer protocols. The ZigBee Alliance is an association of companies that cooperate to provide software interoperability certification and testing. In May 2003, IEEE 802.15.4 standard was adopted. Currently, Freescale Semiconductor is providing RF data modem engineering samples to development partners to adapt to the standard. At present, more than 8 billion Freescale processors have been put into use, the company's embedded electronic solutions are everywhere, and in fact have penetrated into all advanced technology applications.
