is a technology that allows the transmission of data, voice, and video via a computer or any other wireless-enabled device without having to be connected to a fixed physical link.
The introduction of mobile computing began in the 1970s with an early yet primitive attempt to provide data communication for commercial aircraft. Later this technology progressed rapidly and is now widely used in most parts of the world. This revolutionary step changed many aspects of our lives, including the way we communicate.
The mobile computing field focuses on complex mobile systems with application-specific requirements that demand high performance. It is a research field of computer systems, which are used on moving objects or on any other object or structure that cannot be stationary.
Long-term evolution (LTE) is a standard for high-speed wireless communication for devices like mobile phones and computer equipment.
This standard has been created by 3GPP and uses the frequency spectrum from 2 to 11 GHz. It offers much higher data rates than earlier standards, with up to 100 Mbit/s download speeds possible. To use such high speeds, you’ll need a compatible LTE-capable smartphone or modem.

role of mobile computing in Mobile Communication
The role of mobile computing has changed many aspects of our lives for example communication, entertainment, and commerce.
With the introduction of mobile communication, mobility is now possible to any individual through devices ranging from simple telephones to complex smartphones.
These days almost every modern phone supports mobile communication features which means that they can send text messages or make a phone call. Mobile communication devices have also become very popular among people of all ages.
also allows us to enjoy multimedia content such as songs and videos on the go. Such devices allow you to store and access your media library with ease, wherever you are. Moreover, they can also connect directly to televisions for sharing and watching content on a bigger screen.
Motorola was the first company that introduced phones in the early 1970s which had all these functions in one device.
Role of Mobile Computing in Mobile Hardware
Mobile hardware specializes in devices that are used on moving objects or on any other object or structure that cannot be stationary. They may be portable or wearable.
Portable devices must be small and light enough to carry around easily, but they also need to be powerful to perform complex tasks.
Wearable devices are worn on the body of its use for various purposes, such as medical devices which monitor a patient’s health or utility meters that monitor a building’s power usage.
Devices that are not portable have to be appropriately designed and made to stay close enough to their users for the wireless communication link to work properly.
Due to their size, these devices must also be able to run on low power, since they may not be able to access large power supplies.
The devices that make up these systems may consist of different components like input-output (I/O) interfaces, sensors, and actuators. I/O is the communication system between a computer and its peripherals such as printers, keyboards, or mice.
The devices that are used in mobile computing include :
- Mobile phones
Main principles of mobile computing
The main principles of mobile computing are −
Mobility is the ability to work remotely, that is with the worker being able to access information from different locations which may be within an office or outside. The worker must have access to all hardware supporting the application along with an ability to work with the application and data on different hardware.
Mobility is the key aspect of mobile software. It can be crucial for the certain case which involves life and death, such as being able to access medical records on a smartphone while being in an emergency or urgent patient care. Similarly, it can help to track machinery that cannot be stationary by using wireless devices that are attached to them.
The main idea of ubiquity is that all applications must be available for use from any location, whether it is at home, outside, in an office, or in transit. The worker should not need to be concerned about physical location when accessing information or working on tasks that require the use of an application.
Scalability is supported by virtualization technologies, where multiple operating systems are installed on a single machine creating the ability to run more than one software package at a time.
This allows users to run different versions of an application (eg Windows 7 and XP) without having to purchase separate hardware which supports each operating system separately.
Role of Mobile Computing
role of mobile computing in Mobile software: Mobile Software is any type of computer program which helps to execute specific tasks on different hardware such as PCs, smartphones, or tablets.
These programs help the user to perform tasks while being on the move rather than requiring them to be connected to a fixed network or workstation.
These applications may include :
Operating systems: A new class of operating systems called “Cloud Computing” has been designed for sending and retrieving data via the internet and also known as Cloud Operating Systems.
Limitations of mobile computing
The main drawback of the use of mobile computing is that it requires continuous connectivity to a network or wireless service provider, availability of high-speed networks, and access to the power source.
This limits its use especially in developing countries where people are not able to afford these services; furthermore, they also lack proper infrastructure for their operation. Another problem faced by users has decreased battery life due to heavy usage of wireless devices.
Due to these limitations, mobile computing cannot be used in all fields but it is the main area of focus for many companies which are involved in developing software for mobile devices including Apple, Google, and others.
They are constantly coming up with new ideas to increase the accuracy and usability of various applications that require the use of smartphones or tablets.
Security issues involved in mobile computing
mobile computing is a technology which helps workers to access data from anywhere. However, the one drawback of this type of connectivity is that it can create security issues.
The major security risk associated with mobile computing is the interception of data by malicious software or hackers who may use this information for illegal purposes. For example, if an important document is accessed from a mobile device by a stranger, they could use it for personal gain.
In order to prevent such issues, different forms of security software and authentication techniques have been introduced which make it difficult to access any data without the user’s permission. This helps to protect the entire system and ensure greater efficiency of mobile computing.
