Mobile Phones
PAST
Beginnings =
Evolution

We can classify the evolution of mobile phone thanks to generations raised during the years:
Other type of mobile phones' applications are the fact that we can send pictures or voice messages. We use as well things like bluetooth or video calls.
CONCLUSION
Need for REMOTE COMMUNICATION
Second World War
('40s)
Handie Talkie H12-16
Until beginning of the years 80s several companies:
Investigated
Sought to offer a system of communication distantly for general public
History of mobile phones
Related to the development and evolution of the radio
First mobile phones
Heavy
Too big
Only used in cars
First Generation 1G
Basic Mobility and Services
Incompatibility
Analog system
Faster and much quieter than its analog predecessor
Digital system
Smaller batteries
More energy-efficient
Second Generation 2G
Third Generation 3G
Capable of transferring voice data, emails, information and instant messages
Global Solution
Multimedia services add high speed data transfer to mobile devices
The future of the mobile telephony is based in a lot of new concepts and elements that will be used for the elaboration and development of these future mobiles. But in this project are going to analyse in depth the following concepts:

- Graphene
- Telephony 5g
- Long battery life

FUTURE
EVOLUTION
We are going to see the evolution of the mobiles phones based in the previous concepts:
1. Graphene
Properties
- It can be 200 times more resistant than steel.
- It can have the similar hardness of the diamond.
- It is as flexible as plastic.
Thanks to these properties, this material will be used to:
a) Develop more sensitive tactile screens
b) Improve the extension (50%) of the life of batteries.
Chinese firms Moxi and Galapad have argued that the market is going to launch 30,000 devices made from this material.
These new devices will be sold for a price of around 360 euros, and they will come equipped with Android system.
2. Telephony 5g
3. Long battery life
If we compare this network with 4G-TLE, we can find that 5G is clearly superior than the 4G-LTE, which currently offers 75 Megabytes per second.
The 5G connection will allow the exchange of data at speeds of up to 1GB per second at a distance of up to two kilometers.
Samsung has been working a lot of time on 5G connections and they affirmed that the development of this network could be launched to the market from 2020.
It is estimated that by 2020 approximately 6,5 millions of people will use these mobile networks for data exchange, besides medical devices, electrodomestics...
Different research groups compete to be the first to get a long battery life. The following cases are the best known and closest to reality in the possible factors for the increasing the battery life:
Many research groups are working on incorporating transparent photovoltaic cells on mobile phones that could recharge the mobile in seconds.
But this would not be the only advantage, because the battery could last weeks.
Another branch of research is focused on the possibility to recharge batteries in a less hygienic, but much greener way: through urine.
The researchers cultured bacteria fiberglass in anodes, which were then inserted in ceramic cylinder, similar to a battery circuit. When urine passed through the cylinders, bacteria break down sugars and other chemicals present in the liquid, accumulating a small electrical charge.

PRESENT
We can notice new aspects on mobile phones like flexible screens or holograms. There are a lot of applications that make our lives easier every day in our mobile phones like:
- The weather
- Camera
- Lantern
- The news
- E-mail
PRESENT
Fenix
Fenix streamlines your Twitter experience. Pictures and video are automatically expanded and fit the width of your phone, swiping left brings up all your mentions, and left again your Activity Feed.
Avast - Mobile Phone and Antivirus
It scans all downloads and installations for hidden software and trojans, and protects you while you browse the web or use internet-enabled apps.
Opera MAX
It crunches down the size of images and videos, can speed up website load time, and typically saves you around a third to nearly half of your general data usage.
