Literature Review On Mobile Technologies Essay


One of the many useful mobile technologies that can be used for handling disaster relief operations is the telemedicine facility. In spite of its little application in the medical world it is still considered as a useful technology for emergency purposes.  Tele medicines is a process that includes diagnosis, treatment, monitoring and education along with expert advice and other needed information from independent site access for helping the patients in recovering from all kinds of medical emergencies.[1].  This technology is very useful cases where occurrences for natural disasters are unavoidable.

The working of the telemedicine technology is described as follows:
Tele-medicines works using transmission devices which include wired as well as wireless connections. The wired connections is done using phone lines and special data lines and the wireless connections range from radio, microwave signals to satellite based links.

Tele communication is an integrated system that consists of computer and telecommunication technologies that are used to provide a face to face communication between the patient and the doctor. [2]

According to a paper about Tele-medicines it was told about the application of this technology in NASA, which will be discussed in the Application of Tele medicines  This paper talked about how this technology helped civilians during the disaster period .


The Tele-medicines was applied early in the 1985 earth quake that took place in Mexico by NASA and this was the relief effort provided by the American Red cross and Pam American Health organisation. [1]. This shows that a patient can be cured of his medical ailments even without the doctor being giving him a direct medical check through.

Tele medicines were also used in 1950’s by anaesthesiologists to treat polio victims and later in the use of micro process controlled ventilators which are managed by respiratory therapist to treat their patients [3].

As far as the Asian Tsunami and earth quakes in Pakistan are concerned, technologies like these could have been used and would have been of great relief for the victims but due to lack of knowledge and awareness, not much took place.


In spite of its efficiency, the Tele medicine service comes along with some major draw backs. According to the study undergo an by the Committee on Manpower for Pulmonary and Critical Care Societies (COMPACCS), the Tele medicine service may become a problem to deal in the near future with the increasing population, and work force trends. [3] So since it is a challenge to deal with, the technologist must find new ideas and new areas for improving this technology.

Ka-band System:

This technology uses ka-band satellites. These use high frequency bandwidth satellite projects that were started in the early 1970s for developing 32-34- GHz satellite communication service.[4]. It is currently used for several mobile services, internet services and other network services. Being a satellite based project it has been used to for several rescue and relief operations in the past and it is still of use in the current world. Some main limitations that exist in this technology is the difficulty of reaching the victims during the disaster periods. The time taken for the rescue team to reach the victims that are caught in the disaster may vary and hence it might be too late to reach them.


Mobile phones help in providing quick sharing of information and quickly raising a lot of relief aid. Mobile phones played a major role in the Asian sea quake disasters. People like the victims of the tsunami were able to communicate with their families with mobile service to let them know that they were live. The SMS service is one of the major achievements in the mobile phones services. When the tsunami disaster took place a lot of people in other parts of the world were ready to contribute by using the SMS service to send money. In Netherlands telephone users could transfer 1.5 euro to Asia funds by tapping the word ‘give’ on the keypad and sending the text message to number 2020.[6] Mobile phones and SMS services come in hand in hand and this is useful for future natural disasters occurring.


“WIMAX stands for worldwide interoperability for microwave access”. It provides wireless access to the internet economically and easily to even people who far away or from the rural areas. It has the ability to reach people at 30 miles. This supports the mobile technology by providing speed wireless access and excellent communication service. This service provides broad band service for metropolitan areas[7] hence proving a more regional service. With WIMAX , there are alternate routes provided for landline during disaster recovery and relief operations.[7] Because of its accessing capability, it can provide a major achievement during disaster periods by allowing victims and survivors of natural disaster to communicate with outsiders and help can be provided in the form relief aids. WIMAX contains 2 major stands which are IEEE802.16-2004 and IEEE204.16e Wimax also provides the added advantage of data backups which can be used in companies when disasters strikes in these places.[7]. By providing back up files government agencies can record the victims of the disasters and take immediate action by sending relief aid to these victims.
