Home Portable Medical 3.10 Wireless Communication Offering a broad portfolio of RF products, Freescale primarily serves the wireless infrastructure, wireless subscriber, generalpurpose amplifier, broadcast and industrial markets. Freescale pioneered RF technology and continues to be a leader in the field by providing the quality, reliability and consistency that is associated with our RF products. 3.11 Introduction to ZigBee Technology The ZigBee Alliance defines low-power wireless communication protocol stacks and profiles designed for monitoring and control of devices in a variety of markets and applications. These include consumer, smart energy, control and automation and medical markets. There are two different specifications (ZigBee and ZigBee Consumer) as well as multiple profiles that focus on specific markets. Freescale provides the necessary building blocks used for both ZigBee and ZigBee Consumer solutions, including hardware, software, tools and reference designs. 3.12 Freescale Solutions with ZigBee Technology The ZigBee protocol stack is designed for monitoring and control applications such as building automation and smart energy. It features self-forming and self-healing mesh networks that help differentiate it from other technologies.

Decision support is not limited to just the bedside. The quality of care often depends on the ability to share vital patient data with clinicians in real time outside the care facility. This means clinicians can provide immediate feedback to attending physicians based on real-life clinical research as well as track treatment paths, and give results beyond the Impedance Coupling walls of the hospital over the patient’s lifetime to improve future treatment methodologies. ZigBee technology is rapidly proving to be useful in these applications. It can help provide greater freedom of movement for the patient without compromising automated monitoring functions. ZigBee technology can be deployed in a number of products that can help ensure better patient care and more effective care tracking by providing cost-effective, low-power wireless technology that can cover large buildings and institutions with mesh networking. Freescale has received ZigBee Certified product status for its ZigBee Health Care wireless health and wellness processing platforms. The ZigBee Certified products status is awarded to products that have been tested and met criteria for interoperability that enable wireless devices to securely and 18 Medical Applications User Guide Switch
eliably monitor and manage non-critical, low-acuity health care services. The Freescale processing platforms awarded the certification include the MC13202FC transceiver in combination with the MC9S08QE128 MCU, and the MC13224V integrated transceiver with a 32-bit ARM7 MCU. These products are optimized for sensing and monitoring applications requiring low-power for battery-operated or batterybacked systems. 3.15 Why ZigBee is Ideal for Wireless Vital Sign Monitoring A ZigBee network for long-term care consists of a patient monitoring system and the network infrastructure to communicate with a central location or caregiver station as well as other mobile devices. Wireless monitoring provides feedback through a gateway to a central server where data is maintained. This data can be accessed by doctors, nurses and other health care professionals between caregiver visits, alerting them to changing conditions that need attention. Wireless monitoring also allows institutions to track care for accountability and insurance requirements. 3.16 Freescale Enables ZigBee Health Care Profile for Medical Devices Freescale solutions with ZigBee technology provide the perfect combination of cost effectiveness, low power, high integration and high performance required for medical monitoring applications. These solutions include not only silicon but also software, development tools and reference designs to help simplify development. Freescale’s BeeStack ZigBeecompliant stack with BeeKit Wireless Toolkit provides a simple software environment Figure 3-18: MC1321x Family Block Diagram Figure 3-15: MC1321x Family Block Diagram MC1321x MCU and Transceiver Switch Impedance Coupling Figure Figure 3-16: 3-19: MC1322x MC1322x Family Family Block Block Diagram Diagram MCU Transceiver Module MC1322x Impedance Coupling Figure Figure 3-17: 3-20: ZigBee Zigbee Transceiver Transceiver Options Options IEEE ® 802.15.4 MC1319x MC1320x MC1321x MC1322x to configure network parameters. This tool allows customers to use a wizard and dropdown menus to help configure the ZigBee network parameters. To learn more about ZigBee technology, visit freescale.com/ZigBee.
