Abstract
A computer network is indispensable for realizing the use of telemedicine. Recently, experiments to provide telemedicine to residents in remote places over a broadband Internet access have been reported. However, if a disaster were to occur with devastation over a wide mountainous area, and telephones and Internet access were to become unavailable, the provision of telemedicine for injured residents in this area becomes difficult. To solve this problem, we have developed 2.4 GHz wireless LAN units with the longest coverage in Japan to date, of 30 km plus at 54Mbps which complies with the IEEE802.11 g standard and the Japanese radio regulations to re-establish communications temporally between disaster devastated areas and hospitals, and so on. We tested them in the disaster prevention drill with the regional fire bureau and concluded that wireless LAN units we developed can transfer high-quality video images and sound good enough for use in telemedicine.
Highlights
Providing prompt and efficient post disaster measures, the opportunity to share and utilize live video images of a devastated area has become very important for disaster-related organizations.Emergency services, such as fire, search and rescue, hospitals, and international help organizations will need to provide much needed assistance to help victims in a catastrophe
This software can measure the maximum transmission of a network. This software was installed onto 2 different personal computers. One of these computers was to be set up to run as an Iperf server and the other one was set up to run as Iperf client
This enables doctors to check patients’ complexion and health condition. This live video image transmission is likely to cut about 1 hour off the time at which a surgery starts after a patient is transported from this drill site to Shinshu University Hospital, whereas without it, it could take up to 3 hours to start surgery
Summary
Providing prompt and efficient post disaster measures, the opportunity to share and utilize live video images of a devastated area has become very important for disaster-related organizations. Emergency services, such as fire, search and rescue, hospitals, and international help organizations will need to provide much needed assistance to help victims in a catastrophe. Examples would be the affected areas in the 2004 tsunami in the Indian Ocean, and the 2005 Hurricane Katrina incident in the United States. Both incidents highlight the need for a communication system that is easy to set up, operate, and that is inexpensive
