Unit 5: Mobile Computing Introduction
(1) Mobile Computing:
Mobile Computing is a technology that provides an environment that enables users to
transmit data from one device to another device without the use of any physical link or
cables. In other words, mobile computing allows transmission of data, voice and video via a
computer or any other wireless-enabled device without being connected to a fixed physical
link. In this technology, data transmission is done wirelessly with the help of wireless
devices such as mobiles, laptops etc. This is only because of Mobile Computing technology
that you can access and transmit data from any remote locations without being present
there physically. Mobile computing technology provides a vast coverage diameter for
communication. It is one of the fastest and most reliable sectors of the computing
technology field. The concept of Mobile Computing can be divided into three parts:
o Mobile Communication
o Mobile Hardware
o Mobile Software
Mobile Communication:
Mobile Communication specifies a framework that is responsible for the working of mobile
computing technology. In this case, mobile communication refers to an infrastructure that
ensures seamless and reliable communication among wireless devices. This framework
ensures the consistency and reliability of communication between wireless devices. The
mobile communication framework consists of protocols, services, bandwidth, and portals
necessary to facilitate and support the stated services. These devices are responsible for
delivering a smooth communication process.
Mobile communication can be divided in the following four types:
1|P a ge
, Fixed and Wired: In Fixed and Wired configuration, the devices are fixed at a position, and
they are connected through a physical link to communicate with other devices. For
Example, Desktop Computer.
Fixed and Wireless: In Fixed and Wireless configuration, the devices are fixed at a position,
and they are connected through a wireless link to make communication with other devices.
For Example, Communication Towers, WiFi router.
Mobile and Wired: In Mobile and Wired configuration, some devices are wired, and some
are mobile. They altogether make communication with other devices. For Example, Laptops.
Mobile and Wireless: In Mobile and Wireless configuration, the devices can communicate
with each other irrespective of their position. They can also connect to any network without
the use of any wired device. For Example, WiFi Dongle.
Mobile Hardware:
Mobile hardware consists of mobile devices or device components that can be used to
receive or access the service of mobility. Examples of mobile hardware can be smart
phones, laptops, portable PCs, tablet PCs, Personal Digital Assistants, etc. These devices are
inbuilt with a receptor medium that can send and receive signals. These devices are capable
of operating in full-duplex. It means they can send and receive signals at the same time.
They don't have to wait until one device has finished communicating for the other device to
initiate communications.
Mobile Software:
Mobile software is the actual program that runs on the mobile hardware. It deals with the
characteristics and requirements of mobile applications. This is the engine of the mobile
