Nowadays, WLAN are provided in almost US hospitals. Recently, interest in wireless systems for medical applications has been rapidly increasing. WBAN: Wireless Body Area Network CIMIT is a center conducting research in order to improve patient care [CIMIT].             2.3 WPAN https://mentor.ieee.org/802.15/file/08/15-08-0154-00-0006-capsule-endoscope-using-an-implant-wban.pdf, [Yuce07] Mehmet R. Yuce & Steven W. P. Ng & Naung L. Myo & After the introducing of 802.11a and 802.11b, WiFi alliance formed and started its work certifying wireless based devices. Summary Each patient lead can be designed as a separate battery-powered Bluetooth device that communicates with a battery-powered Bluetooth-enabled patient monitor. ISO/IEEE 11073-10201 Domain Information Model The devices constantly transmit data from patients and clinicians that can be used for analytics purposes or improved operations. EMSS: emergency medical services system The mentioned challenges are associated with technical implementation [Stankovic05]. A wireless medical device delivered at the right purchase price and service cost will require appropriate design effort in terms of connection control and cost-effective use of the wireless network for data delivery, both real-time and nonurgent. In most of the life, the devices are in sleep mode to save device’s power. The developers have to consider the longevity of the devices and extend it by using such scheduling algorithms and power management schemes that energy consumption should be shared over the whole network, rather than having a few devices or nodes carrying the whole network’s load. The number of nodes in a network can be as many as 65000 nodes. A cyberphysical system (CPS) is a computer system in which a mechanism is controlled or monitored by computer-based algorithms.In cyber-physical systems, physical and software components are deeply intertwined, able to operate on different spatial and temporal scales, exhibit multiple and distinct behavioral modalities, and interact with each other in ways that change with context. These issues could be a motivation for developers to create the better solutions. http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=552302, [McLoughlin06] Eoin McLoughlin, Dympna O’Sullivan,Michela Bertolotto, and David C. Wilson; “MEDIC MobilE Diagnosis for Improved Care”, SAC’06 April 2327, With the advancement of wireless technology, wireless devices can be used to reduce medical errors, increase medical care quality, improve the efficiency of caregivers, lessen the caregiver-lacking situation, and improve the comfort of patients. ASTM issued ASTM F1220-95(2006), a standard guide for emergency medical services system (EMSS) [ASTM F1220]. Integrated wireless technology, these wireless devices could communicate with a gateway that connects to the medical center’s network and transmits data to health data stores for monitoring, control, or evaluating in real time or offline after storage. Airborne modules help these machines have wireless communication, reduce wiring and make it compatible with modern network. Coming along with the urgent development of wireless technology, wireless devices have invaded the medical area with a wide range of capability. With advantages in mobility, transmission speed, QoS and security, WiMAX technology is an excellent choice for telemedicine service providers in both fixed and mobile environments [Niyato07]. Wireless medical devices are for the most part designed and tested in the simulated environments of test labs. 2006, Dijon, France            5.3 Capsule endoscope In emergency situations, real-time health parameter is crucial. This paper is organized as follows: We will briefly discuss the base wireless technologies which current applications are using. The rapid growth of the technologies extends the potential for exploitation of wireless medical application market. CIMIT: Center for Integration of Medicine and Innovative Technology Examples of functions that can utilize wireless technology include controlling and programming a medical device, monitoring patients remotely, or transferring patient data from the medical device to another platform such as a cell phone. As mentioned above, the other application of WiMAX-based network is prehospital management service. A number of physiological monitoring systems based on the motes have been proposed and deployed in real clinical settings. The FDA recommends that manufacturers periodically consult the FCC website for new specifications and updated information. It all started with German physicist Heinrich Hertz (1857-1894) when he discovered electromagnetic waves. Remote monitoring can also help special populations such as seniors, through home monitoring of chronic diseases so that changes can be detected earlier before more serious consequences occur. 10 hot new home medical devices that are lifesavers Published Fri, Jan 29 2016 10:00 AM EST Updated Fri, Jan 29 2016 10:02 AM EST Chris Morris, special to CNBC.com http://www.cimit.org/orfuture.html, [CodeBlue] CodeBlue project IEEE 802.20 will use the licensed bands below 3.5 GHz and provide data transmission speed over 10Mb/s for user speeds up to 250 km/h. Home monitoring systems for chronic and elderly patients is rapidly growing up in quantity and quality [Otto06]. The next section of the paper will be reserved to discuss standards used in wireless medical applications. http://ieeexplore.ieee.org/document/4201256/, [Natarajan07]Anirudh Natarajan, Mehul Motani, Buddhika de Silva, Kok-Kiong Yap_ & K.

Started with Erission’s Bluetooth Project in 1994, Bluetooth technology is considered a Wireless Personal Area Network (WPAN). A Zigbee network can be formed by three types of devices which are PAN coordinator, Full Function Device, Reduced Function Device. When manufacturers submit pre-market notification to the FDA for device clearance or approval, declarations of conformity to these standards may eliminate the need for certain safety and effectiveness data. This is a novel application of wireless technology into in-body patient monitoring [Takizawa08]. A set of standards, so-called ISO/IEEE 11073 or X73[Yao05], identifies nomenclature, abstract data models, service models, and transport specifications for interoperable bedside devices.

Nowadays, thanks to the large-scale wireless network and mobile computing solutions, such as cellular 3G and beyond, WiFi mesh and WiMAX, caregivers can access into vital information anywhere and at any time within the healthcare networks. Bluetooth operates in frequencies ranging from 2402 to 2480MHz with channel bandwidth of 1MHz in US. They also patented the photophone in that year. Patient’s data is easily transferred around the hospital. While many devices help extend and improve quality of life, a … Medical devices that incorporate wireless technology introduce some unique risks that should be addressed. The following part will identify challenge of deploying wireless networks based solutions in medical care. The data rate is defined at 720 kbps per user. In addition, the standards identify state planning goals and objectives for EMSS communications.             5.1 CIMIT As the mater of fact, most wireless network based devices are battery operated; therefore, the design of a system must not require devices to expend excessive energy. Using WBAN technologies to transmit data from monitoring devices, such as Capsule Endoscope [Takizawa08], to outside body, these applications used to monitor the digestive organs such as the small intestine by video or successive image data. Implanted medical devices are one of the most profitable businesses of the U.S. healthcare industry. However, there are many other challenges associated with deployment of a new technology. List of Exhibitors @ the Digital Corner, ESCardio2018 in Barcelona. The standards’ primary goals are “providing interoperability for patient-connected medical devices and facilitating the efficient exchange of vital signs and medical device data in all health care environments”[Cooper02]. We have also identified standards being used in wireless medical applications and location of wireless network in a healthcare system. Connecting medical devices including IV pumps and vital sign monitors to a hospital's network also will lead to greater productivity and improved care.
