Advantages of VoWLAN and Its Application Instances

For a hospital, a voice service (VoWLANs) is built on a wireless LAN. If other interface problems have been solved, it can help staff ----- especially nurses ----- save time and reduce workload and pressure.

Through the use of data spectrum wireless technology, many enterprises find that they can place voice communication on wireless data networks, wireless local area networks (WLANs, it also creates a more effective communication system for the campus environment that most employees often live in.

Industries such as medical, hospital, and retail are more inclined to look for solutions such as VoWLAN. It may be difficult for a mobile enterprise to locate and contact the right person at the right time. With the continuous development of VoWLAN technology, it is becoming more practical and common to locate specific nurses, doctors, salespersons or managers on campus or through a voice system.

Even if VoWLAN can save time and achieve better customer service, these features are most effective only when wireless services are at the peak point ------ no annoyance from other electronic devices.

Moreover, interference may come from the most unexpected services. Most people still expect their calls to be dropped in the elevator or parking lot. But most people expect the phone to continue working in the following environments: Office kitchens (People reheat their lunch with radio waves); when they wander through the office; when they cross the security camera; approaching the CEO's office (maybe the CEO is using his new iPhone) or under the fluorescent light. However, each of the above devices may produce enough interference to disrupt wireless phones and other wireless communication devices.

In a hospital building in the Baptist Medical Center of Wake Forest University, the staff found it so difficult to solve the interference problem that the hospital almost had to reconsider the solutions that could save the staff a lot of time.

For Wake Forest University employees, Vocera's VoWLAN Technology ensures that they can save time in the following ways: Find a proper nurse when patient needs care; locate a wheelchair and take it to the specified room. In the first several buildings on the Wake Forest campus, the implementation of Vocera went quite well, and the staff quickly saw the expected results promised by the technology.

Similar to Star Trek communications badges, Vocera badges use VoWLAN and speech recognition technologies to improve the communication quality of mobile workers in campus environments. Press the button to call the system operator. After this start operation is complete, all other commands will be executed by universal speech. You can allow the operating system to call a specified person or department as needed. The call is connected to the recipient, who can choose to answer or cancel the call service through voice commands.

Although most of Vocera's implementation and usage are progressing smoothly, a particular building proves problematic. But nurses are not engineers or administrators in the IT field after all. For them, there are always problems that need to be solved because they don't have time to deal with idle communication systems. This results in a long time to gain a comprehensive understanding of interference issues.

When Vocera delivers a dedicated Engineer to the accident location to solve the problem, it turns out that the engineer has a wider idea than anyone else. If you avoid a dedicated Engineer at the beginning, the problem will continue and require more help to solve.

Vocera engineers started using Cognio's SpectrumExpert, a tool for analyzing the problem of wireless spectrum soldiers. Vocera has been using SpectrumExpert for two years. Running the software on a laptop allows the specialist to accurately find the equipment that causes interference through the voice communication of hospital staff.

The result is that the interference comes from a legacy patient monitoring system, which enables Vocera's solution to generate a skip frequency when trying to find the best working frequency. There are also some frequency jumps from the interference of nearby buildings, which is easier to solve than the previous one.

However, due to the complexity of testing medical equipment, the Wake Forest University is still evaluating whether to use the Vocera solution in that particular building-continue to use the solution in other buildings-and whether to replace the patient monitoring system with the legacy one. Vocera VoWLAN solution's early and continuous successes in other buildings present a strong example for its continued use on campus.

Vocera's confidence in Cognio's SpectrumExpert capabilities comes from its initial experience with the software. Vocera originally ordered the software for purely evaluation purposes. When Vocera's first engineer began his exploration in this field, all engineers in this field immediately want to have a copy of the software. Other Software analyzers cannot meet Vocera standards in field operations like SpectrumExpert.

"For us, Cognio's SpectrumExpert software helps us better understand our customers' wireless network problems," said Robin Jellum, A Vocera system engineer. "Using SpectrumExpert helps us maximize our customer network capabilities and keep them at the forefront of technology.
