Spectrum management Light, colors, AM and FM radio, and electronic devices make use of the electromagnetic spectrum. This determines which frequency ranges can be used for what purpose and by whom. They can be used within range of the mobile telephone site used to house the equipment required to transmit and receive the radio signals from these instruments. For all wireless Internet access, see Wireless broadband.
Some of these tasks include connection to the internet, lower phone bills via internet calls, finding location in a new city, etc. Radack enumerates some of the major benefits of wireless devices when she states, Many organizations and users have found that wireless communications and devices are convenient, flexible, and easy to use.
Users of wireless local area network WLAN devices have flexibility to move their laptop computers from one place to another within their offices while maintaining connectivity with the network.
Wireless personal networks allow users to share data and applications with network systems and other users with compatible devices, without being tied to printer cables and other peripheral device connections.
Users of handheld devices such as personal digital assistants PDAs and cell phones can synchronize data between PDAs and personal computers and can use network services such as wireless email, web browsing, and Internet access.
Further, wireless communications can help organizations cut their wiring costs. In other words, concern is often raised about the safety of information that is exchanged with the use of these devices.
Radack enumerates the security issue involved with the use of wireless devices when she writes, Wireless networks transmit data through radio frequencies, and are open to intruders unless protected. Intruders have exploited this openness to access systems, destroy or steal data, and launch attacks that tie up network bandwidth and deny service to authorized users.
Another risk is the theft of the small and portable devices themselves. In the first place, it is important to assess the many threats and attacks which wireless devices are prone to and the extent of damage that is done. Furthermore the size of some wireless devices makes it easy for it to be lost or stolen.
Thus what can be done to prevent this scenario? Security issues concerning wireless devices are diverse and approaches vary from one country to the other. What lessons can be learnt between various approaches.

4) Medical Device Connectivity - As wireless LANS (WLANs) are quickly becoming the connection of choice for patient monitors, electrocardiograms (EKGs), portable CAT scans and other medical devices, hospital wireless networks need to improve information flow and the quality of care.
The rapid integration of mobile devices into clinical practice has, in part, been driven by the rising availability and quality of medical software applications, or “apps.” 2 Apps are software programs that have been developed to run on a computer or mobile device to accomplish a specific purpose.
