Future of Mobile Computing

The future of mobile computing seems to be on a rapid development, with manufacturers releasing new products all the time, and the aim of that is making the devices lighter in weight with bigger screens and more compatibility and speed of the devices.

With cloud computing becoming a service that people are preferring to use over saving files on their PC s or pen drives  due to system crashes and loss of data this i fast becoming the way to store files, even though there are some security concerns i am sure these will be addressed and solved in the near future.

 

User interfaces will also be changing and developed into more user friendly and will have the characteristics of what we used to see in the movies. The interfaces will probably become more natural. The ability of touch is taking over the conventional keyboard, so in the future the conventional keyboard might be the thing of the past.

Batteries are getting slightly better, but with all the faster processors and high end graphic cards, surely in the future they will have to work on making the battery last muh longer with all the high end components.

With the continuing evolution in wireless networks including WiMAX and LTE, it won’t be long before we can truly have a mobile cloud environment where anything and everything can be virtualized and simply passed onto mobile devices. You can greatly reduce the amount of power that laptops, smartphones and tablets require and therefore see some impressive battery life numbers.

Devices will come dependent on cloud storage therefore leaving out huge hard drives and other sorts of storage devices and will only be dependent on cloud storage. There reducing power usage.

Mobile Computing Devices

There are various types of mobile devices used for mobile computing. These are some examples of a few.

Laptops- Various types with different specifications for diffrent types of users.

Net book- small portable computer, designed mainly with Internet access in mind. Net books are low power, low weight and (usually) low cost.

GPS- Global Positioning System (GPS) is a navigation and precise-positioning tool

Tablet PC- portable, slim, internet-connected computers. They are bigger than smartphones but operate in a similar way with touchscreens and downloadable apps.

Smartphone-  a device that lets you make telephone calls, but also adds features that you might find on a personal digital assistant or a computer

Limatations of mobile computing

  • Insufficient bandwidth: Mobile Internet access is generally slower than direct cable connections, using technologies such as GPRS and EDGE, and more recently HSDPA and 3G networks. These networks are usually available within range of commercial cell phone towers. Higher speed LANs are inexpensive but have very limited range.
  • Security standards: When working mobile, one is dependent on public networks, requiring careful use of VPN. Security is a major concern while concerning the mobile computing standards on the fleet. One can easily attack the VPN through a huge number of networks interconnected through the line.
  • Power consumption: When a power outlet or portable generator is not available, mobile computers must rely entirely on battery power. Combined with the compact size of many mobile devices, this often means unusually expensive batteries must be used to obtain the necessary battery life.
  • Transmission interferences: Weather, terrain, and the range from the nearest signal point can all interfere with signal reception. Reception in tunnels, some buildings, and rural areas is often poor.
  • Potential health hazards: People who use mobile devices while driving are often distracted from driving and are thus assumed more likely to be involved in traffic accidents. (While this may seem obvious, there is considerable discussion about whether banning mobile device use while driving reduces accidents or not.) Cell phones may interfere with sensitive medical devices. Questions concerning mobile phone radiation and heath have been raised.
  • Human interface with device: Screens and keyboards tend to be small, which may make them hard to use. Alternate input methods such as speech or handwriting recognition require training.

Advantages and Disadvantages of Mobile Computing

Advantages:–

1- Increase in Productivity- Mobile devices can be used out in the field of various companies, therefore reducing the time and cost for clients and themselves.

2- Entertainment- Mobile devices can be used for entertainment purposes, for personal and even for presentations to people and clients.

3- Portability- this would be one of the main advantages of mobile computing, you are not restricted to one location in order for you to get jobs done or even access email on the go

4. Cloud Computing- This service is available for saving documents on a online server and being able to access them anytime and anywhere when you have a connection to the internet and can access these files on several mobile devices or even PCs at home. 

Disadvantages:–

  • quality of connectivity- as one of the disadvantages, mobile devices will need either WiFi connectivity or mobile network connectivity such as GPRS, 3G and in some countries even 4G connectivity  that is why this is a disadvantage because if you are not near any of these connections your access to the internet is very limited.
  • security concerns- Mobile VPNs are unsafe to connect to, and also syncing devices might also lead to security concerns. accessing a WiFi network can also be risky because WPA and WEP security can be bypassed easily.
  • Power Consumption- due to the use of batteries in these devices, these do not tend to last long, if in a situation where there is  no source of power for charging then that will certainly be a let down.

History of mobile computing

HISTORY OF MOBILE COMPUTING

The Idea of mobile computing has only been around since the 1990s. Since then, Mobile computing has evolved from two-way radios that use large antennas to communicate simple messages to three inch personal computers that can do almost everything a regular computer does. People can’t go to their local Starbucks and not see a laptop linked up to a hotspot Static network. This actually used to mean radio transmitters that operated on a stable base, usually with the help of large antennas. 2 way radios used by police officers were also considered mobile technology but now, it means people can connect wirelessly to the internet or to a private network almost anywhere. As long as a person has one of the devices capable of wirelessly accessing the internet, they are participating in mobile computing. Chances are, you have done it with a laptop computer or a personal digital assistant or PDA.So they decide to came up with an idea of portable devices These days, Pocket PCs are another way to conveniently access the internet on the earth devices that have been developed for mobile computing have taken over the wireless industry. This new type of communication is a very powerful tool for both businesses and personal use. The portable computer has change computing world confiered to hundred years’ back. from huge machines that could not do much more than word processing to tiny hand held device. It offers the opportunity to bring people together and give everyone access to a greater wealth of information and knowledge, and to share their knowledge with others.

 

WHY MOBILE COMPUTING
Mobile computing is all about portable and small computers, which includes PDAs (Personal Digital Assistants) like mobile phones, palmtops, laptops etc. In this growing technological world, people are much bound to work on computers and Internet. People are attracted towards mobile devices because of their major features such as-
Mobile computing can be defined as the ability to use technology that is not physically connected to any static network. Nowadays, most laptops and personal digital assistants(PDA) all have wireless cards or Bluetooth interfaces built into them for very Good mobile internet access.
