ITGS Portfolio Draft 2
Criterion A: Presentation of the issue
My portfolio will be based on a newspaper article published on the 16th of September 2008.Titled: Mobile phone ban sought for train drivers in wake of crash. It can be found on http://www.thewest.com.au/default.aspx?MenuID=2&ContentID=98102. For many, many years Mobile phones have been a fast way of communication in our world rather than using letters and/or emails. Mobile phones have also been a huge problem because they cause a lot of different hazards.
Hazards like cancer, diminished hearing and worse crashes are sometimes caused by mobile phones. These crashes especially happen in trains and airplanes and have become a common issue of discussion between aviation industries like Boeing and Airbus. If a mobile phone is switched on or used during flight or train journeys, since they operate at a different frequency than the airplanes or trains, they could intercept, scramble or block the frequency thereby prohibiting communication between the pilots and the airport towers or the train engineer and the station.
This might cause crashes which endanger the life and property of other people on the train or airplane. Sometimes the passenger isn’t the only problem, the pilot or train engineer are too. The recent 2008 train crash was caused by the train engineer who was making calls and texting to his friend when the crash happened. Every year there are approximately 3,000 train accidents. Every year approximately 1,000 people will die as a result of train accidents. Almost every 2 weeks a train derailment causes a chemical spill, leading up to evacuations of local residents and most of them are as a result of some electrical malfunction and also of mobile phones.
Criterion B: The IT Background of the Issue.
Mobile phones have become more and more popular since its creation. They have been improved lot in the way they work, their compatibility, design, durability and versatility. Nowadays everyone has a mobile phone. Everywhere you go you see people with mobile phones chatting away. On trains especially, there is an unusual amount of talking. This disease called the mobile phone has even caught onto people like the drivers of trains and cars, whose little mistake due to absent mindedness can cause the lose of lives and properties.
The use and production of mobile phones are improving every year. These new mobile phones operate at about 2100 MHz (2.1GHz). They also have the ability to receive more than 800 different frequencies. This ability in the mobile phones therefore becomes a problem when an individual is on a train because the mobile phone could intercept the train frequency used for communication by the drivers of the train and the control station. This interception between the two frequencies could cause perplexity between tower and driver and therefore lead to a fatal accident.
Falling mobile phone prices and slowing growth in new handset production is leading to lower revenue in the handset market worldwide in the years ahead, according to iSuppli Corp. Overall market saturation and related moderation in sign-up of new subscribers also is finally taking a toll on device market economics. The average selling price of a mobile phone is now $129, about $36 lower than it was just two years ago.http://material.htlwien10.at/unterrichtsmaterial/n/howstuffworks-pdf/cell-phone.pdf
Criterion C- The Impact of the Issue
As they have improved, so have the frequencies which they use to transfer information. Mobile phones are everywhere nowadays but few people really care or even know what kind of diseases they can cause. Continuous use of mobile phones over a long period of time can cause damage to the ear and it could also affect the brain. It could also cause cancer. Use of mobile phones in public transports has also been a problem. Reports on trains especially have also caused significant problems.
Mobile phones increasing frequency which is called “Radio Frequency” nowadays have now become very similar to that of the trains and can interfere with information passed to and from the train. The currently used frequency in some mobile phones which are called 3G, or third generation, is the generic term used for the next generation of mobile communications systems. The systems enhance the services available today and offer multimedia and internet access and the ability to view video footage. This similarity in frequency causes interference in information transmission which can be quite critical in the case of trains because the information might be about where the train should not go to avoid a crash.
The effect of mobile phones could also cause the government a lot of money in buying new trains, removing the wreckage of trains which are usually caused by mobile phones and pay the families of the harmed or dead on the crash. A recent train crash which was caused by mobile phones was on September 13, 2008. A Commuter train with 225 aboard slammed into a freight train on a winding route in Chatsworth. More than 135 are injured and 17 dead. Many stakeholders who would be very interested in this information would be companies like Nokia, Sony Ericsson, Samsung and Motorola. They could use this information to make better mobile which wouldn’t interfere with surrounding frequencies. http://www.latimes.com/news/local/la-me-traincrash13-2008sep13,0,2874450.story
Criterion D: A solution to a problem arising from the issue.
The use of mobile phones and their dangers, in this case directed at trains can be limited through a number of ways. The best solution would be to set up a network which would intercept all calls going to the train and also from the train thereby preventing people from making or receiving calls. The missed call would then be converted into text later on, after the individual has left the train and sent to his/her mobile. Another solution could be to setup phones in the trains much like the ones found in aircrafts for making calls. These phones should operate at a lower frequency than the train so whenever an individual wants to make a call he/she can simply use his/her credit card or money to pay and make the call.

Criterion D: A solution to a problem arising from the issue.
The use of mobile phones and their dangers, in this case directed at trains can be limited. Rules should be made that any passenger in the train even the train engineers should have their mobile phones switched off before boarding the train. Also anyone caught with their mobile phone switched on should be fined since hey are endangering the lives of other people on the train. This can be achievable by placing watches or police men at points before the entry onto the train and also in the train to make sure people don’t switch on their mobiles. This could also increase employment because there are many train stations and many officers would be needed to watch over. Flyers and posters could also be posted in the train station and outside it to tell and also remind people that their action (switching their mobile phone on in the train) could lead to a train crash and therefore death.

Criterion C: The impact of the issue.
Mobile phones have been a source of communication for a little more or about10 years and they have been improved in the way they work, compatibility, design, durability and versatility. As they have improved, so have the frequencies which they use to transfer information. This brings us to the main idea of the topic, Mobile phones and trains. Mobile phones are everywhere nowadays but few people really care or even know what kind of diseases they can cause. Continuous use of mobile phones over a long period of time can cause damage to the ear and it could also affect the brain. It could also cause cancer. Use of mobile phones in public transports has also been a problem. Reports on trains especially have also caused significant problems. Mobile phones increasing frequency which is called “Radio Frequency” nowadays have now become very similar to that of the trains and can interfere with information passed to and from the train.

The systems enhance the services available today and offer multimedia and internet access and the ability to view video footage. These services operate at 2100 MHz. (2.1GHz). This similarity in frequency causes interference in information transmission which can be quite critical in the case of trains because the information might be about where the train should not go to avoid a crash. This effect of mobile phones could also cause the government a lot of money in buying new trains, removing the wreckage of trains which are usually caused by mobile phones and pay the families of the harmed or dead on the crash.

http://telephonyonline.com/wireless/metrics/mobile_phone_production_013006/
This brings us back to the usage of trains on mobile phones on trains. This can influence the passage of information in the train to the driver. Mobile phones work on almost the same frequency as trains do. Therefore they can intercept each other and cause confusion which might therefore lead to a crash.
