One of the most important aspects of building a successful medical environmental enterprise wireless LAN is enabling transparent user mobility across the network. The proliferation of portable and mobile devices hasuntethered office workers from traditional desktop computing.

 

Modern employees require application access from diverse locations throughout the workplace, as well as seamless connectivity for your medical devices and while on the move. To enable this new mobile workforce, wireless networks require high performance and low-latency roaming to support real-time multimedia medical applications such as voice and video conferencing, vertical industry solutions such as high-speed mobile devices in manufacturing and distribution, automated warehousing, robotics, and medical instrumentation, to name only a few.

 

Organizations also require strong security to protect sensitive information and comply with various medical environmental / industry regulations such as HL7, HIPPA, PCI, Sarbanes-Oxley, and FERPA. Modern wireless networks provide robust security by requiring authentication of users and devices prior to allowing role-based network access and subsequently securing communications with strong encryption methods. However, the balance between mobility and security has caused an unpleasant trade-off for organizations due to the time-consuming processes that strong security methods require. On one hand, high performance mobility can be provided when relatively weak security is implemented with an Open or WPA2-Personal WLAN, but this leaves sensitive corporate data at higher risk of exposure.

 

On the other hand, much stronger security can be implemented with WPA2-Enterprise, lowering the exposure risk of sensitive corporate data, but resulting in poor mobility performance due to the time-consuming 802.1X authentication process. Thus, the introduction of more secure WiFi networks solved one problem (security) but created another (roaming performance). With our Cisco equipment we keep your medical environmental wifi strong and secure !
