Assess the probable difficulties of the IT executives at St. Luke's view of wireless networking as a key lever in their quest to increase clinician productivity and improved patient care.

The St. Luke’s Health Care System has hospitals that use wireless local area networks (WLANs) for their mobile use of technology. They effectively use wireless technologies that allow the health care system to provide services 24 hours a day. The applications use in a wireless format help with Diagnosing patients and charting their progress, provide up to date prescriptions distribution, applications for blood management, case management, and other critical application for services needed in the industry. One of the difficulties the IT executives found was in their Critical care units. In this unit running hard wires would mean moving parts of the building such as ceiling panels. Moving the ceiling panels or putting wires in the walls would stir up dust and microbes. Dust and microbes in the Critical care units pose a threat to patients. When it came to case management, wireless network and devices allowed for real-time access to information. This allowed for a higher level of patient care and a timely discharge wherein the pass, it would take time to gain access all the needed information.

The longer to get or gain access to files of a patient the longer it took for solutions for their care and processing to another patient. Patients at meal time could now get services such as the ordering of menu food before the cut off time. The wireless system also allowed for a dietitian to see current patient information and meals restriction, supplement or needed tube feeding data. The wireless system allows for the doctor to put into the system what each patient is needed in terms of diet and nutrition and that information would be available even after the doctor is no longer on call for that patient.

In 1998 the WLAN was deployed for St. Luke’s but it kept dropping connections causing users if they were on the move to reestablish connection and re-login to applications. The building itself was also a problem. It was not built for technology and the walls were constructed with chicken wire, which interfered with radio waves. The original design of the building made some areas have a weak radio signal. There would be interference with microwaves and other devices being used in the building. More users became more of a problem with performance slowing down due to users.

Analyze how the Mobility XE enables the IT department to centrally manage all wireless devices used by clinicians .

Mobility is a mobile VPN built specifically for highly mobile workers such as staff at St. Luke's Health care system. Mobility XE is easy to set up and change configurations. The VPN is strong with security that uses single sign-on authentication, multi-factor authentication, along with user reauthentication and encryption. Mobility XE has seamless InterNetwork Roaming with application session persistence. This technology allows for wireless sessions on a server even with the signal is lost. Mobility XE addresses concerns such as intermittent network coverage and effective management of multi-network mobile computing deployments. The level of scalability allows for the deployments and support of thousand mobile workers along with the ability to be a constant reliable tool in use.

With so much data that is being made and altered for updated information, Mobility XE automatically switches compression of data based on the current interface speed. This function removed the need or have an administrator to change the setting for specific users.

Critique the Mobility works solution and recommend one change to the solution to provide better productivity and improved patient care.

Mobility is a software solution form NetMotion Wireless. It is installed on each wireless client device such as a tablet, laptop, or handheld device. The job to Mobility is to maintain connections between the device and the NetMotion mobility server. St. Luke’s have two servers that do this job in the case that if one fails, there is a backup server taking the workload. If a device should go out of rang of the server or received interference, the application switches to standby mode. Once there is a clear connection again, the user application resumes where it last left off. That is the only issue I see with Mobility works solution. The challenging part is the security and connectivity issues that impact performance. Once the device is out of range, the application must stop until it is back in range for finishing the process. Devices not recognized by the Mobility XE server are not allowed to access the network. This allows for St. Luke to have encryptions for all wireless data communications. If a device is lost or stolen, it can be quarantined by the network managers. However, the device cannot be reported stolen or lost until it is reported, giving a window of time to crack the encryption of the device. This can be done by an employee not understanding the importance of security and passing the information to an unknown attacker. Devices would have the opportunity to leave the area of the hospital, an attacker could download a spy software on the device, and it could be returned to the hospital with spyware and reconnected to the network of St. Luke's.
