What is Mobile Computing?
Mobile computing is a technology in which various information such as audio, video, etc. is transmitted through computer or other wireless device. In this, mobile devices are not physically connected among themselves.
Following are the main concepts of mobile computing-
- Mobile communication
- Mobile hardware
- Mobile software
Mobile communication is an infrastructure system in which the communication system runs continuously without any hindrance and reliability. Necessary protocols, services, bandwidth and portals are required to facilitate the communication system and in this stage the format of data is also ensured.
This includes mobile devices and device components that receive and access communication services. These devices include portable laptops, smartphones, tablets, personal digital assistants (PAD). All these devices are configured in full duplex, in which they are able to send and receive signals at the same time. To send a signal to a device in full duplex, one does not have to wait until the other device finishes sending the signal. It goes on continuously.
Mobile software is a program that runs on mobile hardware and works according to the characteristics and needs of the mobile application. We can also call it a mobile device engine.
In other words, it is the operating system of the mobile device. It is the main component of the mobile device that operates the device.
Mobile Computing Applications
- Airline and Railway Industries
Now the FCOM manuals of the airplane have been completely replaced with PDA and Tablet PCs. In addition, PDA or Tablet PCs are used for grading in simulator training. It helps the user to know the flight time table and access the ticket related information. The use of mobile computing also provides the facility of virtual checking for regular customers.
This technology facilitates the control of cargo and airline baggage. The process of bagging has been made faster and easier by mixing information directly from the database by scanning the barcode on the luggage using the mobile computing application.
- Transporting Industry
Information about real-time shipment of goods can be obtained using Computer Aided Dispatch (CAD). Customer service can be further enhanced with the help of real time tracking system technology. Apart from this, with the help of this technology, communication between fleet drivers and dispatch centers makes transportation easier. With the help of this technology, real time information of passengers at kiosks and bus stops can be detected.
- Manufacturing and Mining Industries
Mobile computing technology is used for “process monitoring” in the construction and mining industry. It can also be used in real time management of parts, tools, machines and goods.
Mobile computing applications are used to track orders, purchase verification and delivery confirmation.
- Banking and Financial Institutions
Various wireless banking services such as fund transfer, payment of bills, checking of account balance and other functions are done by smart phones or PDAs. Apart from this, handheld devices can also be connected to the ATM wirelessly via Bluetooth.
Advantages of Mobile Computing
Following are the major benefits of mobile computing:
- Location Flexibility
Through this, users are able to work by establishing a connection from anywhere, so that the user does not need to work at the same place, apart from this, the user can do many things at the same time.
- Time Saving
Many times our entire time is wasted during travel or when coming back from office, but now anyone can work from anywhere on mobile without accessing computer, accessing major documents. This will save time and unnecessary expenses.
- Enhanced Productivity
With the help of mobile computing, the user can work effectively efficiently from anywhere according to his convenience.
- Ease of Research
Users first had to go to different places for research and then search it back in the system. But now researchers can feed information on mobile during work. Apart from this, they do not need to go to different places for research, now researchers can do research work through communication medium like e-mail.
Mobile computing has made audio narrative video recording possible. The user can now easily access various information, movies, educational information, and now with the availability of high speed internet at a normal cost, entertainment content such as news, film documentaries, games, etc. are easily available for everyone. This was not possible before mobile computing.
- Ease of Doing Business
It is now easier to do business through secure internet connection. Adequate measures are being taken to authenticate the user to make the services accessible to other people from the security point of view. Seminars and meetings and other informational services can be conducted easily by video and voice conferencing, saving both travel time and expenses.
Disadvantage of Mobile Computing –
- Lack of connectivity
Mobile computing requires mobile network connectivity or WiFi connectivity such as –GPRS, 3G 4G. In the absence of connectivity it is impossible to access the internet. In today’s time, it is necessary to have good quality internet connectivity.
- Security concerns –
VPNs may be unsafe to sync a device for security. Apart from this, WiFi connectivity can also be at risk as personal data can be stolen by breaking WPA and WEP security.
- Power Consumption –
Mobile devices use batteries that do not last long, if there is no source of power to charge the battery in such a situation the device will shut down. Therefore, it is necessary to have electricity available everywhere.
