Hello, everyone!
Today, I would like to continue to share with you the medical application scenarios on WBAN (Wireless Body Area Network) technology.
Currently, there is no standard for a wireless body area network that is specifically designed for healthcare purposes. ZigBee/IEEE892.15.4, WLAN, GSM (Global System for Mobile), and Bluetooth are the most often used wireless technologies for medical monitoring (802.15.1).
Except for the GSM standard, all of these technologies are commercially accessible and optimized for short-range communications. These wireless protocols are designed for general-purpose sensor networks and so are not ideal for medical applications.
If these devices are employed for wireless body area network applications, interference and coexistence difficulties must be addressed. Other medical bands, such as MICS (Medical Implant Communication Service) and WMTS (Wireless Medical Telemetry Service), are explicitly regulated for medical monitoring by communication commissions around the world, in addition to unlicensed ISM (Instrumentation Scientific and Medical) bands.
Due to its low transmitter power, recently developed short-range low data rate ultra-wideband (UWB) technology is another intriguing technology that could be employed for body area network applications.
A frequency of roughly 400 MHz has been employed as a common transmission band in systems to monitor medical implant devices and the state of inner organs. The MICS is an unlicensed, ultra-low-power mobile radio service for sending data to assist diagnostic or therapeutic tasks connected with medical devices that have been implanted.
This frequency band can be utilized to facilitate wireless communication between medical implant devices, allowing for more comfort, mobility, and improved patient care.
In order to monitor and differentiate each unique implanted device and a patient in a large number of patients wearing implanted devices in the same setting (e.g., a hospital), dependable wireless networking is required.
Implanted wireless nodes in the body of a patient should form a wireless body area network, allowing one or more implanted devices inserted in the bodies of a number of patients in a healthcare setting to be controlled with minimal complexity.
I will continue to share on this article in the following post.
